Let’s work together

Some of the largest companies in the world today all have one thing in common. They were all founded by two people. A quick examination of the history of globally renowned organisations such as Apple, Google, Twitter, Microsoft, EBay and Yahoo, reveals that each of them had two different people at the helm. Some such as Steve Jobs and Steve Wozniak at Apple and Bill Gates and Paul Allen at Microsoft are famous. Others such as Evan Williams and Biz Stone at Twitter, and Ben Cohen and Jerry Greenfield of Ben and Jerry’s fame, less so. Each had different personalities and brought a variety of characteristics to the role. That magical dynamic helped ensure the international success for these companies. The glass industry has embraced the culture of partnership. Before glasstec there were a flurry of collaborations involving Bucher Emhart Glass, Tiama, Bottero, Iris Inspection Machines and Heye International. The reasons for the cooperations are varied but a general theme is the rise of digital glassmaking and automation. Each company believes a fully automated plant is only possible if technology suppliers work together. There is a huge amount of glassmaking knowledge contained within these individual companies Sharing this expertise will push the industry forward dramatically and help it compete against rival materials such as PET.

The plant (pictured) in Acatlán de Juárez, Guadalajara, Mexico was formerly opened on October 18, 2018. The aim of the Saverglass Mexico plant is to respond to the increasing trend for premiumisation in the drinks sector, for example: tequilas and mezcals in Mexico, fine wines and spirits in the United States and rums in the Caribbean. The plant is situated in the state of Jalisco, a few kilometres from the town of Tequila, and 40km from Guada-

lajara, the 2nd largest city in Mexico City. It is also near the ports of Manzanillo serving the Pacific Coast and Veracruz on the East Coast, and is also close to major roads and railways leading to the rest of the Americas. In its initial phase, the Saverglass Mexico plant will operate a furnace that is capable of producing 85,000 tonnes, or some 120 million bottles in two colours: Extra White flint and Antique glass. The construction project began in July 2017 and took 327 days to complete. The plant is profiled on page 8 of this issue of Glass International.

Shareholder urges O-I to sell European business A major O-I shareholder wants it to sell its European business. In a letter sent in mid September, hedge fund Atlantic Investment Management suggested O-I should sell the business and initiate a $1 billion share buyback programme to boost what the investor said was an undervalued share price. New York-based Atlantic owns a 5.93% share of O-I.

In response O-I said: “We take seriously the input of all our shareholders and O-I senior leadership has maintained an open and active dialogue with Atlantic for many years. “Our management team and Board of Directors are continually focused on ways to improve long-term value creation, and as with all shareholder input, we will consider

Atlantic’s perspectives in that context.” In the letter, Atlantic Investment President Alexander Roepers said the sale of the European operations could fetch up to $3.8 billion. That money could be used to cut O-I’s nearly $2 billion debt, reduce the exposure to currency fluctuations, and fund the stock buyback.

Forglass secures Ardagh and Krosno glassmakers orders

Tiama and Bottero deal

Tiama and Bottero have signed a partnership agreement for joint co-operation between the two groups. The agreement results from discussions conducted by managers from both companies from a technical and sales perspective. Tiama said strong synergies between the strategic visions of Bottero and Tiama were immediately established and the potential value of the technical cooperation in the glass container market was evident.

Glashütte Freital orders GEA’s BisCat technology

The works will be performed in the first half of 2019. Forglass will provide its own

equipment, including belt conveyors, bucket conveyors, vibrating chutes and diverters.

Wiegand-Glas chooses Tiama German container glassmaker Wiegand-Glas has invested in Tiama’s IQ Scan as a Manufacturing Execution System (MES) in its four facilities. The glassmaker has adopted the Tiama system to replace existing solution at its plant in Ernstthal. The project also includes several iAfis systems upgrades to Tiama IQ Scan in the three other plants in Steinbach am Wald, Großbreitenbach, and

Schleusingen. Wiegand-Glas started to use Afis technology in 1996. The company produces more than eight million glass containers for the beverage and food industries every day. The Tiama IQ Scan’s role is to collect data from all machinery involved in the glass process, including Tiama inspection machines, laboratory and mould shop. With its web design, all

actors of the glass plant can monitor their production lines, understand where the losses are coming from and can therefore increase their efficiency. The Tiama IQ range was designed to support glassmakers with real-time data, and allow access to relevant information required for the decision-making process. Wiegand-Glas and Tiama have cooperated for 25 years.

Cortex Glass introduces temperature monitoring system Cortex Glass has introduced BlankWatch, a temperature monitoring system. The glass supplier has developed a system in order to measure real time and continuously different temperatures at the blank side of an

IS-Machine. The BlankWatch system provides real time information about various temperatures, including left mould, right mould, neck ring, plunger and parison. It uses one small thermal camera per section. The tem-

perature measurements are precise and are exactly timed with IS-machine timing. Mould related temperature information is displayed in trend graphs together with the thermal images on an interactive Touch Screen.

German container glassmaker Glashütte Freital has ordered a compact plant for the cleaning of flue gases from melting furnaces. The glass manufacturer selected GEA’s BisCat technology thanks to its low space requirement and combination of several process steps in one reactor. “During my working life I was in touch with GEA several times and experienced them as a competent, reliable partner said Hans-Bernhard Führ, Glashütte Freital’s General Manager. The new furnace has a melting capacity of 150t/d. Commissioning alongside GEA’s emission control plant is expected in March 2019.

Reckmann in Mexico

German thermocouple producer Reckmann has appointed Graphite Glass as its Mexican partner. It means that, thanks to this partnership, Reckmann has a direct market presence in Mexico with a local service for its customers. Graphite Glass was founded in 2012, and has 25 years experience in the glass containers business in Central and South America. Reckmann has manufactured since 1970 and specialises in the production of thermocouples for the glass industry.

Polish glass production supplier Forglass has been selected to start a project with two glassmakers. Krosno Glass has chosen Forglass for cold furnace repair work that needs to be performed at its plant. The work will start in January and be completed by February. Krosno Glass is one of the largest manufacturers of glassware in Poland and an established supplier to more than 70 international markets. Ardagh Glass’s Germersheim plant has chosen Forglass to build a new cullet feeding line and to modernise its batch feeding line.

Saverglass inaugurates Mexican site




Saverglass inaugurated its Jalisco, Mexico facility recently. Glass International’s Ricardo Sanchez* attended the official opening of the $120 million facility which will make 100 million bottles a year.


averglass, the French producer and decorator of premium and premium plus glass bottles for wines and spirits, has officially opened its new production plant near Guadalajara, Mexico. The new $120 million plant has a single multicolour furnace capable of producing 85,000 tonnes and can produce 100 million bottles a year. It wants to be closer to the American market to reduce delivery times and continue with the excellence in service. The Saverglass CEO, Mr Loic Quentin of Gromard and its managing director Jean Marc Arrambourg, officially opened the new plant. The facility was built in less than a year and employed more than 300 collaborators from

cullet; a composition building of 536m2 and 37 metres high; silos that allow 15 days of production autonomy; a decorated building of 6700m2; a packing warehouse of 2700m2 and a warehouse of finished product of 22000m2 (with the possibility to extend to 50000m2). The furnace is a home-made design, as Mr. Arrambourg explained. “We made this oven, we designed it and we made the plans. It is 100% a work of Saverglass.” He added that the batch house was not made by them but they did design it. The factory follows all the environmental standards of existing plants. It does not use heavy metals and the acid etching process will leave water “as clean as the water that went in.” “We have a standard, which is a high level of quality, not only of service but also a quality of life for our people and the neighborhoods we live in. It’s important to us,” he added. The plant currently has one furnace, with the capacity to operate with a single or double gob, depending on the line. The facility has space to build more furnaces. The plant was supplied by a number of international technology suppliers. Italian group BDF Industries provided the four IS machines, furnace pressure and inversion valves as well as

6 plant with the region’s road and rail system. The decision to build the plant in Mexico specifically in Guadalajara - was due to the strategic location that allows Saverglass to have close proximity to the two coasts of the United States and also to Central America and the Caribbean, as well as being located just over one -hour from the town of Tequila. The location is key because it allows customers to be served by road or ship thanks to the highways that expedite deliveries in Texas and the southern states of the country and thanks to the Mexican ports of Manzanillo and Veracruz that allow shipping by sea. Construction work began in July 2017 and took 327 days to complete. The first bottle was produced on June 10 this year. Saverglass invested $120 million in the development of the plant that includes one multi-colour gas furnace; an administrative building with amenities (lockers and showers); an 8500m3 warehouse for raw materials and

7 batch charger stirrer mechanisms and contol instrumentation for the furnace and channels. BDF has supplied equipment to all five Saverglass plants around the world. Its Italian compatriots Zecchetti contributed the production lines and Emmeti supplied pallet equipment. French companies Iris and Tiama supplied the inspection machinery. There is a significant growth in the premium spirits sector in the Americas, since Mexico has the annual growth of close to 10%, while the whiskey and rum markets grow at an annual average of 5%, which would represent a demand for 150 million more bottles for the year 2021. These markets were already served by Saverglass from its plants in France and the United Arab Emirates. But it became clear that it was necessary to build a new plant in America to continue with the process of premiumisation in the region. The new plant will also speed up the delivery process because customers will receive the bottles faster due to its proximity.

Saverglass.indd 2

08/11/2018 14:41:49

Saverglass even thought of the geography of Mexico itself when it built the plant. The country has a tendency to suffer from earthquakes. To address this the company built a solid infrastructure that includes 20 piles and 700 columns to add firmness to the building. They also took into account the importance of industry 4.0 (digitalisation). Mr. Jean Marc Arrambourg pointed out that digitisation ‘is very important for Saverglass, because it affects all the traditional methods that guided its processes in the past, therefore it is important to use the appropriate technology and apply it to our production activities’. He added Saverglass uses digitalisation in a large part of its machines, even in the cooling area. An example of digitalisation is its system of operations planning (SOP) which allows customers to ensure that they will always have the amount of bottles they require. “The purpose is to deliver the right amount and the right quality at the same time. We can not risk the availability of our product because we want to ensure the satisfaction of our customers.” That is just one of the examples that distinguish Saverglass from the rest of the glass producers in the world and Mexico. Additionally, it has distinguished itself by focusing on the premium sector of bottles for wines and spirits. The Jalisco facility is capable of not only producing high-quality glass bottles made of extra flint glass for superior clarity and brilliance but antique coloured glass. Saverglass says the plant will even be able to offer decorations, such as hot stamping, screen printing, electrostatic coating, with acid etching and sandblasting which is just around the corner. Additionally, 50-60% of the glass used is recycled with the intent to find ways to use even more of it Quality is a factor that stands out in the French firm, as well as innovation and design. The factory in Mexico intends to continue with that legacy,

� BDF Industries supplied four IS machines to the plant.

which is why the 3,500 Saverglass customers can be sure that their products will continue with the high quality standards that distinguish the brand. Saverglass and its incessant tendency to innovate have created the Art and Touch system, which is intellectual property of the brand. Art and Touch allows you to design and decorate in 3D. The French producer is distinguished by its extra transparent glass bottles, for its clarity, brightness and texture when touching the bottle. Quality and reputation are backed up by the quality management programme, which is important because it guarantees customers that they will be able to receive the quantity of bottles they require. That is why Saverglass has ISO 22301 Certification of Business Continuity Management System, which distinguishes it from the competition because this guarantee is available in several plants, not just in one. Saverglass has a catalogue of 250 of its own designs of bottles for wines and spirits, and there is a unique proposal because they are producers and decorators of bottles, which adds value for their customers. This is an opportunity for small producers of wines or spirits because they can choose designs from the catalogue or request a new one. The Saverglass Mexico site enables the glassmaker to have a manufacturing presence on three continents and to sell within 80 countries to over 26,000 customers. The optimism prevails among the members of Saverglass because they predict to maintain the growth of 10% that they have had for more than 20 years. They have also thought about the construction of two more furnaces, although the question is not if they will do it, but when they will do it. �

US overview: The Silica Chronicles

What do US and Chinese trade tariffs mean for the glass industry? Richard McDonough examines the impact tariffs will have on several sectors. The article looks at aspects within several industries that either manufacture glass or use glass to produce or package products. on certain imports from China that were estimated to be valued at $200 billion. A total of 5,745 types of products were targeted with this additional tariff. To put into perspective the breadth of these tariffs, the list of tariffs is 194 pages in length. President Trump also announced that as of January 1, 2019, the additional tariffs will increase to 25%. These tariffs are in addition to two previous waves of 25% tariffs on imports from China implemented by the United States government; the two previous tariff actions involved products valued at approximately $50 billion. As each of those tariff actions were implemented by the United States

government, China then implemented tariffs on products imported from the United States into China. American tariffs now target an estimated $250 billion in imports from China. Chinese tariffs now target approximately $110 billion in imports from the United States. According to the Office of the United States Trade Representative, China has acted, adopted policies, and implemented practices ‘related to technology transfer, intellectual property and innovation [that] are unreasonable and discriminatory and burden or restrict United States commerce.’ Continued>>

trade situation that began earlier this year with the United States of America imposing broad-based tariffs on steel and aluminium to protect its military preparedness has evolved into a major trade war. Two of the major combatants are the United States and China. The European Union, Canada, and Mexico as well as a host of other nations are also affected. As one country decides to add a tariff to a specific product, another nation decides to add a tariff to another product of their choosing. In late Summer this year, President Donald Trump of the United States announced that as of September 24, 2018, an additional 10% tariff would be placed

Environment US overview: The Silica Chronicles

Businesses that produce glass as well as businesses that use glass to manufacture and package other products are affected to varying degrees by these tariffs. Companies that operate solely within one country’s borders and do not export their products to other nations may be largely unaffected by trade tariffs or, more likely, may not directly feel the impact of tariffs on their specific products. Indirectly, though, these same firms may find certain products required for their operations are now priced higher because of the tariffs. In turn, those ‘unaffected’ businesses may have to streamline operations to get better efficiencies and lower their costs, raise prices on their products to their customers, decide to accept lower profit margins, or do a combination of all three. Many businesses that operate globally have been directly affected by these trade tariffs. Some companies that manufacture glass as well as other businesses that use glass in producing or packaging their products have had to deal with the initial broad-based tariffs on aluminium and steel. While many businesses outside of the aluminium and steel industries were not directly affected with the initial broadbased tariffs, as additional tariffs have been added on specific types of products, the impact has been felt by many more firms. In many cases, the specific impacts of those additional tariffs have not yet been felt by businesses. But the concerns of business leaders are very real.

Welcomed Some within the glass industry have welcomed tariffs on glass products being imported into the US. While specific tariffs were being considered for inclusion in the third wave of tariffs by the United States government on imports from China, Mr. Paul Coulson, Chairman and CEO of Ardagh Group, spoke of the need for tariffs on glass containers. “The US glass market is being adversely impacted by a substantial rise in glass containers being imported from China and Mexico,” stated Mr. Coulson, according to a transcript by Seeking Alpha of the investors’ call meeting held by Ardagh Group on July 26, 2018. “We’ve previously noted the level of what we believe are effectively subsidised

import glass containers being sold into the North American glass market,” he continued. “And we welcome the recent inclusion of glass containers on the proposed list of Chinese-manufactured products to be subject to new importation tariffs…We view initiatives to ensure a level playing field and fairness and trade practices as essential to the long-term future of the North American Glass Packaging industry.” On September 18, 2018, the Glass Packaging Institute (GPI) issued its Statement on Tariffs for Chinese Food and Beverage Containers. This trade association represents businesses in the glass container industry in North America. “The Glass Packaging Institute testified and provided written comments in support of tariffs on Chinese glass

containers imported into the United States,” according to the Statement. “The request covered glass bottles and jars for the food, beverage and cosmetics industries.” “Considerable evidence exists that Chinese glass container manufacturers have been supported for decades by various government subsidies that lower the cost of their production,” the Statement continued. “In the US, the glass container industry supports a highly-skilled hourly workforce at 43 plants. Domestic glass container manufacturing companies also spend considerable capital to ensure compliance with air quality and other US regulations.” According to the GPI: “Tariffs on Chinese glass containers will help level the playing field for domestic glass container

manufacturers. US customers should not be significantly impacted by the tariffs since there is domestic latent capacity, and glass containers are imported into the US from other countries in addition to China.” “We are optimistic the tariffs may expand production of glass containers,” the Statement detailed. “The domestic glass container manufacturing companies will adjust production levels based upon customer demand. Opening of new, or restarting of closed plants, is at the discretion of the manufacturing companies.” The GPI stated that the volume of glass containers imported into the United States from China had increased by 40% during the past five years. During the same time period, the trade association indicated that domestic glass container manufacturing plants had their volume decrease by 8%. The Statement indicated that imports from China represented about half of all empty, unfilled glass containers imported into the United States from all other nations during 2017. A total of 11 glass container manufacturing plants closed in the United States between 2005 and 2018, according to the GPI. The trade association indicated that ‘these closures represent 20.3% of the domestic glass container footprint, leaving 43 plants in 21 states.’ Collectively, more than 3,650 people had been employed at those 11 plants, according to the trade association. “This represents roughly 25.4% of the industry’s current hourly workforce of 14,350,” it said. “Chinese glass container imports have placed additional pressure on domestic glass container production.”

Wine industry The wine industry is one of the largest purchasers of glass bottles in the United States. Exports of wine from the United States to other nations are critical to this industry. “United States wine exports, more than 90% of which are from California, were $992,784,153.00 from January through August of this year,” stated Ms. Gladys Horiuchi, Director of Media Relations of Wine Institute.

“This almost one billion dollars in wine exports represents an increase of 1.31% by value for the time period of January to August 2018 as compared to the $979,929,721.00 in wine exports during the same time period in 2017.” A total of 256,750,485 litres of wine was exported from the United States from January to August of 2018, according to Wine Institute. This was an increase of 0.62% from the 255,160,293 litres in volume of wine sales during the same time period in 2017. Wine Institute reports that the top 10 export markets for California wines are the European Union’s 28-member countries, Canada, Hong Kong, Japan, China, South Korea, Mexico, Singapore, the Philippines, and the Dominican Republic. According to Wine Institute, as of September 24, 2018, the new total tax and tariff rate, when compounded, will equal 79% on wines imported into China from the United States. Wine Institute indicated that this rate includes the 10% tariff on United States wine imports to China that that nation added in September. This tariff is in addition to, according to Wine Institute, a previous 15% tariff increase implemented by China in April 2018. These actions are in response to the United States government increasing tariffs on certain consumer goods from China, according to Wine Institute. “China continues to be an important market for California wines, but tariffs put our products at a price disadvantage,” stated Mr. Robert ‘Bobby’ Koch, President and CEO of Wine Institute. “We will continue our full slate of promotional activities in China to engage Chinese consumers who are increasingly attracted to California wines. We are confident that the popularity of California wines will continue to grow.” Tariffs are also affecting American businesses that need to package their wines in glass bottles. A number of the wine growers in California have had long-standing practices that minimise the impact of tariffs on glass products. One such business is G3 Enterprises of Modesto, California. “From sand and soda ash to limestone and cullet, Gallo Glass sources all of its major raw materials within the State of California,” according

to G3 Enterprises. Groth Vineyards & Winery of Napa, California, is a customer of G3 Enterprises. “My single largest supplier of glass bottles is the Gallo family,” said Ms. Suzanne Groth, President and CEO of Groth Vineyards & Winery. “Their G3 Enterprises is committed to sourcing 100% of the materials from California, a key factor in my purchasing their product.”

Uncertainty Beyond the wine industry, other industries that utilise glass bottles are also looking at potential impacts from tariffs implemented in this trade war. The spirits industry is one such industry. Brown-Forman Corporation includes a number of whiskey and scotch brands, among other products, in its fold. In July

“Corning Inc. is not experiencing a material impact from tariffs as we manufacture most of our products close to our customers, thereby limiting our exposure to tariffs on cross-border trade,” stated Mr. Dan Collins, Vice President of Corporate Communications for Corning Inc. “These new Chinese tariffs create an immaterial additional tariff exposure to Corning.” Corning’s Gorilla Glass is a type of glass product that is used on a variety of mobile consumer devices such as smartphones, tablets and watches. The company has manufactured Corning Gorilla Glass for use on the iPhone since Apple introduced this smartphone in 2007. Overall, through the years, Corning has provided the glass for six billion devices from 45 brands worldwide, according to the firm. Mr. Collins concluded: “We continue to refine our calculations, identify any potential mitigating actions, and assess any potential competitive advantage gained from the tariffs. We remain hopeful that China and the United States will be able to resolve these trade disputes quickly and tariffs implemented by both countries will be removed.”

2018, China enacted a 25% additional tariff on whiskies imported from the United States. Mr. Lawson Whiting, the Chief Operating Officer and incoming Chief Executive Officer of Brown-Forman Corporation, stated in a news release dated August 29, 2018, that: “There remains significant uncertainty around the duration of recently enacted tariffs, but we have been encouraged by the resilience of our business model as we are working to minimise short-term disruption and maintain our top-line momentum.” The impact of tariffs on glass, as well as other products, has been limited for some businesses. Part of that limited impact is because some businesses have chosen to place manufacturing facilities in a number of countries based on customer needs within those nations.

Leaders within the National Glass Association, which includes businesses in the architectural and window and door glass industries, discussed the issue of tariffs at its recent Glazing Executives Forum in Las Vegas on September 12, 2018. Mr. Connor Lokar, an economist with ITR Economics, was one of the speakers at the forum. Mr. Lokar stated: “Tariffs could be a threat to the business cycle growth…The idea we can do this without a cost is just not a reality. Prices are going to increase…That is really going to be a pressure point for the global economy.” Others within the building industries that use glass have also expressed concern about price increases due to tariffs. During 2018, the Window & Door Manufacturers Association has strived to stop the implementation of tariffs on a number of products used by manufacturers of residential and commercial doors, windows, and skylights in the United States.

While tariffs were not implemented on some of the products initially targeted by the United States government, a number of products used in these industries are now subject to tariffs when imported into the US. Among the glass products imported from China now subject to additional tariffs are toughened (tempered) safety glass, glass multiple walled insulating units, and a variety of products made of pressed or moulded glass. These products are used extensively within the building industries. “The sourcing of material from responsible vendors in China has been a significant benefit of manufacturers in the United States directly or indirectly involved in the manufacturing of windows, doors, and skylights,” stated Mr. Michael O’Brien, President & CEO of the Window & Door Manufacturers Association. “In certain cases, product offerings are simply not viable at domestic production rates and/or costing. “By imposing a tariff on the products listed… manufacturers will likely need to raise prices on finished goods to compensate for the additional costs,” he continued. “The ripple effect of this action will be felt by manufacturers and consumers alike, as finished goods would likely be more expensive. “Furthermore, the possible price increases could result in decreased sales volume, which would negatively impact employment across the United States.” In the next few months, if nothing changes, the tariffs implemented by both the United States of America and China will likely impact the producers of glass as well as industries that use glass in a range of products as well as for packaging. The full extent of that impact is something that is not yet certain. Many business leaders in the glass industry are hopeful that this trade war will end before extensive negative impacts are felt by both producers and customers alike. When President Donald Trump of the United States announced the new wave of tariffs on $200 billion worth of imports from China, he ended his statement with the following wording: “Hopefully, this trade situation will be resolved, in the end, by myself and President Xi of China, for whom I have great respect and affection.” �

Waste gas analysis in glassmaking Sorg’s Dr. Hartmut Hegeler discusses the development of a CO measuring system for glass furnaces. It has been implemented in a factory-suitable design. He states the measurements are reliable and can be easily integrated in the workflow of a furnace operator.


he waste gas analysis in the connection between waste gas filter and chimney has been standard in the glass industry for years. The measurements primarily concentrate on the acquisition of nitrogen oxides (NOx) to optimise the combustion process and as evidence for the authorities. The acquisition of residual oxygen and carbon monoxide at this measuring point makes no sense. Despite small dust load and low

waste gas temperature after the filter unit, the maintenance cost for the assurance of a reliable waste gas measurement is relatively high (Fig 1).

The Sorg approach The stable minimisation of nitrogen oxides (NOx) in the thermic process of a glass melting furnace can be reached by control-technological measures such as CO control, in addition to others. With

the so-called CO control the control loop is closed by means of measured values of the waste gas analysis. The residual oxygen in the nearstoichiometric area moves at the limit of the measurement accuracy. The CO signal shows a much larger change in this area and is thus rather suitable for monitoring or trimming the fuel/oxidants relation. Continued>>

The near-stoichiometric operation is known to have a significant impact on NOx formation and emission – another reason to use near-stoichiometric combustion. The graphic shows an example of the connection (HC stands for unburned) (Figs 2 and 3).

Implementation Sorg relocates the measuring point for the waste gas analysis close to the process.

Switching valves

This enables the acquisition of nitrogen oxide (NOx), residual oxygen (O2) and carbon monoxide (CO) (Fig 4). Despite the high dust load and the extremely high waste gas temperature within the regenerator chamber, the assurance of a reliable waste gas measurement is possible. The assurance of the longterm reliable measurement requires specific knowledge as well as the careful selection of the applied components. Here, special attention was paid to the fact that suitable equipment is used for operation at the melting furnace and that the maintenance and cleaning effort fit in with the factory operation. The waste gas is exhausted in the regenerator chamber and brought to the cooler via heated tubes and measurement gas probes with ceramic filter elements (Fig 5). The 2/2-way switching valves are controlled by the regenerative reversing so that the waste gas of the withdrawing side is brought to the waste gas analysis via sample gas pump and coalescence filter. By means of a bypass gas flow, which is displayed adjustable on a flow

metre, the reaction time of the waste gas analysis can be reduced. The measuring arrangement has been tested over a long period (Fig 6). The sample gas is filtered and heated. The ceramic filters need to be cleaned every two to four weeks, depending on the dust load of the waste gas. The time required for cleaning is less than 10 - 15 minutes per sensor (Figs 7, 8 and 9).

Measurement evaluation The actual values NOx, CO, and O2 of the analysis technology are available to the controller units as a 4-20mA signal and are displayed dynamically in the furnace picture of the PLC. The measured value trend can be configured as desired. The control structure of the furnace combustion process is important. The CO measured value is averaged as a 4-20mA signal in the PLC system and fed into the ratio controller as the actual value.

ďż˝ Fig 9. Measurement protocol.

ďż˝ Fig 10. Measurement protocol 2. The CO signal trims the target value of the non-adjustable gas/air ratio in adjustable limits. Disturbances are thus identified and eliminated. The combustion process is optimised near-stoichiometrically. This is the prerequisite for low energy consumption and minimal NOx emissions. Target value deviations can be provided arbitrarily with alarm signals. Thus, the furnace operation is facilitated and the process is made transparent (Figs 9 and 10).


To control the combustion process in glass melting furnaces more transparently and effectively, Sorg further developed the CO measuring at glass melting furnaces and also implemented it in a factory-suitable design. The measurements are reliable; the maintenance costs are manageable and can be integrated into the workflow of the furnace operator without any problem. The operator will thus be provided with an instrument that replaces the previous NOx measurement with a much more sensitive procedure. Thereby, he has the opportunity to optimally operate the melting furnace regarding emissions and energy consumption. ďż˝

Events review: Phoenix Award

Phoenix Award celebrates Oliver The 48th recipient of the Phoenix Glass Person of the Year Award, Oliver Wiegand, was handed the award at a glittering reception recently.


embers of the glass industry’s Phoenix Committee celebrated the achievements of Oliver Wiegand, joint CEO of WiegandGlas at a reception in his honour. Mr Wiegand is the 48th recipient of the Phoenix Glass Person of the Year award. He was presented with the award at a black tie reception held in Konstanz, Germany. The Phoenix Committee, made up of a number of glass technology suppliers, nominated Mr Wiegand for his work in bringing the glass industry forward. The committee highlighted his commitment to new technology and his openness to work with suppliers. During his acceptance speech, Mr Wiegand said he felt like he had won an Oscar. He said: “There is one little difference between this and an Oscar. You can receive an Oscar many times in your career but you only receive one Phoenix Award in your lifetime.” He thanked his wife, father Konrad, and cousin Nikolaus - who is also a joint owner of WiegandGlas - for their support. He said: “Nikolaus is the second most important person in my life and who I sometimes spend more time with than my wife. We are of different characters and whenever we discuss a decision he comes from a different direction to me. I really appreciate his opinion and the trust we have together.” He also praised two colleagues for their loyalty and dedication to Wiegand-Glas: Karl-Heinz Mann, Head of Forming and Burkhard Zipfel, a retired Plant Manager. Wiegand-Glas operates four container glassmaking plants in south east Germany and two glass recycling facilities. It manufactures eight million items a day and employs 2000 people. Mr Wiegand’s family has had connections to the glass industry for 448 years and started production of glass in 1540 in central Germany. Mr Wiegand took over the joint ownership of Wiegand-Glas in 1997 with his cousin Nikolaus. Since then he has also been chairman of International Partners in Glass Research (IPGR), Vice President of Germany’s BV Glas association

This year’s Phoenix Committee Chairman, Graham Womersley, of Pennine Industrial Equipment, said an unprecedented seven past recipients were also in attendance. “We never had that before. It is great credit to Oliver and his standing in the industry that so many have travelled from so far to be here tonight. “I can say with confidence that the recipient of the 2018 Phoenix Award through his forward thinking, vision and willingness to embrace new technologies is not only shaping the European container glass industry but the global glass container industry by helping to move glass forward in a greener, more sustainable way.” He added: “We’re here tonight to recognise Oliver’s pioneering attitude towards glass production, research and development of new technologies. “The industry has benefited greatly from his openness to work with suppliers to trial and develop new technologies. “Wiegand-Glas was the first container plant to install and prove NIS machines, cullet and batch pre-heaters and gob assist technologies. “His furnace technology means WiegandGlas has some of the cleanest and most efficient furnaces in the container industry. The use of batch and cullet pre-heaters mean that the energy consumption is below 3MJ/mt of glass. “Not only are Oliver and his family leaders in glass container production, his desire to embrace new technologies has led the Wiegand group to become a world leader in glass recycling.

� Main picture: Mr Wiegand with this year’s Phoenix Committee members.

� Right: A total of 98 guests attended the event.

“Everyone in this room knows how important this is not only to the industry but for the protection and preservation of the planet. One of the first cullet recycling plants was installed in 1970 by the Wiegand family. Oliver has been involved in the drive to install the latest technologies and it now provides some of the best processed glass in the world. This enables the Wiegand-Glas group to run a green glass container furnace at 97% cullet with a CSP reject level below 0.7. “Approximately 80-95% of Wiegand glass containers are manufactured from Wiegand-Glas cullet where I’m told the industry standard is 63%. “Another great leap forward is that there is now a research programme which includes the upcycling of dust from the cullet recycling plant to create additional new glass products. This is at the forefront of recycling. Not only does he believe in the advancement in container glass development in his own group, but Wiegand-Glas under his leadership provides technical support to more than 100 glass plants around the world. “I’m sure you’ll agree that Oliver Wiegand is a most worthy and much deserved recipient of the 2018 glass person of the year.” � An interview with Mr Wiegand appeared in the June 2018 issue of Glass International, page 12.

glasstec: exhibitors give their feedback

More than 42,000 people attended the glasstec in Düsseldorf in October. Glass International spoke to some of the exhibitors for their thoughts on the event.


ig data and digital glassmaking were among the themes at the glasstec event. glasstec exhibitors said they were happy with the amount and the high quality of the visitors, although some commented that numbers seemed down compared to previous shows. Tiama’s Marketing and Communication Manager, Ursula Baudry, said the show had been a great success for the French company. “It has been a really interesting experience for us. We introduced a new concept called YOUniverse and we were happy to see the pride of our team and

then the interest our customers showed towards this concept. “Youniverse is our way of describing the smart factory. It provides users with business intelligence possibilities through five areas of expertise: intelligence, monitoring, traceability, inspection and service. “Basically customers got the chance to discover this Younivese for the first time when they stepped into our booth and entered the Tiama Youniverse.” The booth included Tiama machines, virtual experiences and a huge screen where the Youniverse concept was introduced. Continuing the digital theme, Sorg together with its partner Borton Lawson, demonstrated a virtual reality environment which allowed booth visitors to explore a melting furnace, based on a Gallo Glass furnace in Modesto, California. Fred Aker, Sorg’s Sales Director, pictured next page, bottom right, said: “The digital world has become a trend and the leveraging of data and making more use of it will definitely become more commonplace in the future. “Visitors who used the virtual reality set up were impressed and they were surprised to know it was built using existing Inventor data.” He added: “It’s been a very good show, it was great from out of the gates. Tuesdays have traditionally been slow but it was busy from the very beginning.” Another popular stand was the Glass Technology Continued>>

they are generally satisfied. The general feeling is that 2019 will be a good year in the container glass industry.” Mexican engineering company FAMA was exhibiting at glasstec for the first time. Its Sales and Marketing Director, Luis Zertuche, reported a successful event. He said visitors from around the globe had attended the Mexican company’s booth. The group had launched a new full servo machine which had attracted a lot of curiosity. “FAMA was formed 75 years ago but was dedicated to the container business unit of Vitro. But now we are more open to the market and we have a strategy to start penetrating the globe. “Our strategic plans see FAMA as a global supplier and global solutions provider for the container glass sector.” Kinga Horodek, Assistant to the CEO at Forglass, said it was the third time the batch and furnaces company had exhibited at the event. “It’s been far better because now people are finding us rather than us finding companies. We’re more established as a major player within the European industry now. “Since the last glasstec we have grown as a company. We have more staff, new designs and technology. The company philosophy is to give good service and we use all our own people, there are no sub contractors. We also use all our own equipment and fabricate it in Poland. “It’s been a successful four days because we had lots of arranged meetings but also lots of meetings with new clients.”

Services booth in Hall 14, which highlighted the virtual reality project it has partnered with tech start up VRMT. Even late on the last day of the event, visitors were still waiting to try the virtual programme. VRMT’s Tony Pawinski said: “We have some really good interest from machine suppliers and customer alike. We had some fabulous comments, several people said it was the best industry-change product they had ever seen at glasstec.” Simon Parkinson, of the UK’s Parkinson-Spencer Refractories, said they had welcomed visitors from all around the world. He said “It’s been a successful show for us and we have seen most of the customers we wanted to see. It’s been busy, on a par with previous glasstec’s I have been to and there have been a few prospects that have come out of it. It’s also good to catch up with other colleagues in the industry.” Marc Meersschaut, futronic sales executive, pictured centre this page, said: “Everyone is here and everyone can exhibit their new technologies. It is also an excellent opportunity to meet customers and reinforce good relationships. “We had a successful trade fair. For the first time, we received orders at the fair. “We have had visitors from everywhere: South and Central America, USA, Europe of course and a lot from Asia, but very few from Africa. The visitors have been high quality people who can decide. “There have been technical people and people who work in the glass factories who want to learn about new technologies. “I have spoken to a lot of people at the show and

Events review: glasstec

The next glasstec will be held in two years time between October 20 to 23, 2020 in Düsseldorf.

Mark Foerch, Sales Manager, Temperature Sensing at BASF, was highlighting the synergies between BASF and the Chemetall organisation, after BASF acquired the company two years ago. He said “It’s been a good show and we have had meetings with specialised people. We have had a lot of interest in the new temperature sensor designs. We can show how we can optimise their cost ownership and give them better longevity on the thermocouples that they currently use.” Italian vacuum pump and compressors manufacturer, Pneumofore, highlighted the benefits of its Rotary Vane technology and in particular its UV50 vacuum pump. “The response from visitors to glasstec was consistently positive, with many high-level conversations with both new and consolidated international customers, which indicate significant collaborations as we approach 2019.” �

glasstec visitor numbers rise 4.47% More than 42,000 visitors attended this year’s glasstec. More than 70% of trade visitors travelled to Düsseldorf from abroad. Trade delegates travelled from 120 countries to visit the 1280 exhibitors

in the nine halls at the Messe Düsseldorf.

The overall number of visitors was a 4.47% increase from the 2016 edition, when 40,200 people attended. It is 2.3% fewer visitiors than the 2014 and 2012 editions when 43,000 people attended each event. The high proportion of executives from top management (more than 70% of visitors came from this decision-making level) underlined the quality of the fair. The range of products and services was also reflected in the conference programmes and special shows. Exhibitors reported promising new contacts and concluded good to very good business deals. The favourable situation in the industry was also reflected by the positive atmosphere in the halls. Wolfram N. Diener, operative Managing Director at Messe Düsseldorf, said: “No other trade event can present such a plethora of forward-looking solutions, products and applications. This is also appreciated by the constantly rising proportion of international visitors.” Egbert Wenninger, Chairman of the Board of VDMA’s Glass Technology Forum and Chairman of the glasstec advisory board, said: “Many high-level specialist discussions that looked likely to lead to orders were held with visitors to the fair. “Machine manufacturers were clearly focused on the issues of digitisation and networked production. “Digitisation has reached the glass industry. Many exhibitors are working intensively at developing future-proof products.” Dr. Johann Overath, Director General of Bundesverband Glasindustrie, said: “Glass is a trend and this year’s glasstec has made this perfectly clear again. “The industry keeps moving and the current upswing evidences that the millennia-old history of the material that is glass continues with amazing innovations.” The next glasstec will be held in two years time between October 20 to 23, 2020 in Düsseldorf.

he conference organised by BV Glas discussed market trends and focussed on ‘The Environmental and Climate Policy in Germany & Europe’, as well as ‘Challenges, Opportunities and Risks for the Glass Industry.’ Dr Johann Overath, BV Glas Director General, was the keynote speaker with a presentation titled ‘Markets – Facts and Figures’. The German glass industry is booming, he stated. In the first six months of 2018, the sector experienced a soaring growth in revenue. This reflects the stable economic upswing and high foreign demand for German glass. He said: “We represent the economic and environmental policy interests of the glass industry in Germany, including container, flat, special glass, glass fibres, tableware, processers and water glass. “In 2017, the total revenue was €9.7 billion, which was 2.6% more compared to 2016. The glass imports in the EU in

2017 were 68%. EU glass production experienced a 2.3% increase in 2017 compared to 2016.” BV Glas is involved in environmental policy, climate policy, energy policy, product policy affairs and standardisation. The glass industry revenue in 2017 included: 15.1% production of special glass and technical glass, 10.1% glass fibres, 5.1% tableware glass, 19.7% container glass, 39.7% flat glass finishing and 10.4% flat glass manufacture. He said: “In terms of imports, the top three most significant countries of origin of foreign glass goods in 2017 were China at 11.2% of total imports, the USA at 9.3% of total imports and Poland at 8.7% in total imports.” He concluded: “Glass is a product that has an inherent circular economy. It is a permanent material. A high recycling rate underlines the sustainability of glass. The glass industry contributes to the circular

economy mind-set by optimising the consumption of resources such as energy, water and bench material. “Projects that have already been implemented show the extent to which heat recovery can be used.”

Emissions trading The next speaker was Christiane Nelles BV Glas Energy and Climate Policy Advisor, who focused on ‘EU Emissions Trading: Post 2020’. She discussed ‘What can Companies Expect in the Future?’ She said: “The European Emissions Trading Scheme (ETS) is a cap and trade system. For example, Company A sells permits and Company B buys permits. The EU has a cap on the total amount of certain greenhouse gases that can be emitted.”

In terms of carbon leakage, some sectors covered by the EU ETS need a high share of allowances to safeguard their competitiveness. For this, Carbon Leakage (CL) protection is a crucial aspect. She continued: “CO2 prices are are already rising due to an expected shortage. Even if you receive certificates from your authorities the amount of the so called free allocation will decline due to reduced benchmark costs and your costs for EUETS will rise. But CO2 included prices in the electricity will hit the industry with full force. “Other than a few energy intensive sectors, the glass industry is not included in the EU-ETS electricity compensation scheme. Therefore indirect costs will be much higher than direct costs.” Mr Overath followed this up by discussing ‘Best Practice: Energy Saving in the Glass Industry with Energy Efficiency Networks (EENs)’. The glass industry has been consistently optimising the energy efficiency of its production processes for many years. “The Energy Efficiency Networks Initiative is a nationwide agreement between the German government and German industry associations. BV Glas joined on 3rd December 2014. Since then, five EENs have been established.” The minimum requirements for EENs include five -15 companies exchanging ideas and experience over two - three years to jointly increase energy efficiency. The networks’ goal is for companies to achieve an increase in energy efficiency over the long term, which will potentially result in a noticeable reduction in energy costs. Another requirement includes a network being initiated by a network facilitator

and the participating companies being supported by advice from qualified energy consultants. The stakeholders are a network facilitator and moderator, such as BV Glas. “In terms of an energy consultancy service, the BV Glas EENs include Multisector Rennsteig Energie. The technologies covered at the network meeting include compressed air, fans and pumps. This year, the network GlasNET 2.0 won an award from the German government for successfully participating in the Energy Efficiency Networks Initiative. It was a great success for the glass industry. “We have also presented two initiatives to save CO2 energy. The German government paid tribute to the enterprises in the network for their efforts to improve energy efficiency and tap into their knowhow transfer potential.”

Circular economy Sheryl Webersberger, Product Policy Advisor, highlighted the ‘Circular Economy Package – the Implications for the Glass Industry’. Ms Webersberger said: “There are two processes addressing industrial manufacturing and lifestyle. “A circular economy addresses processes. This is a closed looped system as opposed to a linear economy. Based on the principle of take, make, use and throw away. A circular economy is a regenerative economy. There is a glass contribution to a circular economy – glass can be regarded as an inert and permanent material.” The closed loop includes disposable glass containers and returnable glass bottles. The rule of thumb is that 10% cullet saves 3% energy.

She concluded: “The properties of glass meet all the requiremets to have two closed loops in place. With one loop glass packaging priovides re-use solutions in order to prevent waste. In Germany we have reuse systems in place particularly for the beer and mineral water segments. With the second loop glass packaging is recylced into new glass packaging, where high glass recycling rates have already been achieved. Therefore glass is truly a circular economy material.” The programme of events also included a one-day conference organised by the glass division of the German Mechanical Engineering Industry Association (VDMA). The conference was themed Crosslinked Production and new Technologies and was split into two sessions – the morning was dedicated to hollow glass and the afternoon to flat glass. There were six speakers in the morning session. Speakers were Dr Markus Schoisswohl of MSC who spoke about Future Processes in glass production and high end finishing, Zippe’s Joachim Ullrich who discussed Digital Glass Batch Production, Erik Muijsenberg of Glass Service, Dr Thomas Bewer of Bucher Emhart Glass, Harald Zimmermann of Verallia and Markus Frank of Horn Glass Industries. �

Environment Recycling: Oman project

Sultanate of Oman to build Middle East’s first glass recycling plant Glass International’s Sheena Adesilu spoke to two of the men behind the project, Sheikh Hilal Humad Al Hasani and Ramesh Mani, to find out more. � Sheikh Hilal Humad Al Hasani (right) and Ramesh Mani (left)

than 90,000 tonnes of glass thrown into the landfills in Oman per annum and an average of about 4000 tonnes a day being dumped into the landfills between Oman, UAE and Qatar. “The demand for glass within the GCC is perceived to have a consisten growth of 5% each years for the past few years. There is no efficient and organised glass recycling system within the GCC in operation and Oman is going to be the first to cater to a varied range of glass manufacturers within the GCC and Asia.” The PEIE, which comes under the partonage of the Ministry of Commerce and Industry of Oman, hopes to solve the recycling problem. With this project, the annual savings in terms costs of raw materials, natural gas and furnace life expansion by using ready to use processed glass cullet from NGRC could save Omani glass manufacturers a substantial amount and reduce their batch costs by over 30%. The plant is expected to be in operation by the end of 2019. The aim is to meet the needs of all the major glass manufacturers on a day-to-day basis within the GCC, Asia and capacity permitting, globally. Mr Mani also specified that the project is the first step and the groups are

investigating multiple recycling projects such as PET, plastic, paper, rubber and metal. The owners also plan to have the project at multiple locations within and outside the Sultanate. Sheikh Hilal and Mr Mani welcomed new potential investors for the second phase of the project. Mr Mani, said: “The credit for this project goes to Sheikh Hilal Humad Al Hasani who has supported my project plans with his support, encouragement and most importantly infrastructure. “He has facilitated with his wide contacts getting the right and likeminded investors for this project from the Government and private sectors. So without him, this project would not have been possible.” The benefits of glass recycling include for every tonne of cullet replaces 1.2 tonnes of raw materials and melting recycled glass uses 10% less energy. Statistically, glass recycling has saved 350,000 tonnes of CO in the UK and reduces emissions by 50%. In addition, there are a lot of uses for glass cullet.

he first glass recycling plant within the Middle East is to be built in Phase 7 in the Sohar Industrial estate, Sultanate of Oman. The project will be named the National Glass Recycling Co (NGRC). NGRC will be the first such facility open within the Gulf Cooperation Council (GCC) group of countries. It will have a 650t/day capacity and be fully automated. The glass recycling plant is particularly designed to meet the needs of varied glass manufacturers within the GCC region, such as container, float, sheet and perfume glass in terms of specifications, volumes and pricing. The plant is a project exclusively promoted by Mr. Ramesh Mani, a well known professional in the glass industry for 32 years in the GCC. The factory has investors from the Omani Government and private sectors. Glass Scan Technologies, Dubai is the Exclusive Technology Provider for the project. The project is supported by Sheikh Hilal Humad Al Hasani, CEO - PEIE and Chairman - Shumookh Investments and comes under the patronage of the Ministry of Commerce and Industry, Sultanate of Oman. NRGC is headed by Mr Mani, Managing Partner at Glass Scan Technologies, Chief Promoter and Managing Partner of Glass Recycling Technologies in the Middle East, within the GCC and in the capacity of CEO and Managing Investor Partner. During an address to delegates at glasstec, Sheikh Hilal Humad Al Hasani provided a presentation about the project which included a video of the facility. He welcomed new investors to the Sultanate, which is the most stable economy within the GCC. In his presentation Mr Mani said 2.4 million tonnes of glass is used and dumped annually in the GCC. “It is high time that we in the Middle East looked at it seriously and addressed it. Currently, we have more

Recycling glass can reduce emissions and the production of raw materials, as well as extend furnace lifetimes by at least two years. Glass Scan Technologies was founded in 2013 to start the glass recycling business. Two senior executives who are involved in the project include Dieter Olschewski, the CEO of Glass Scan Technologies and German company cibite, and André Ommer, the Vice President of Glass Scan Technologies and managing owner of the glassglobal Group. Mr Olschewski is an electrical engineer with a specialisation in mechatronics and spectroscopy. He is also the owner of the patent for the measurement of transparency within the glass. Mr Ommer is an engineer with a specialisation in glass technology. He is responsible for the development of the

recycling project, from the collection of waste glass until the sales of the processed cullet. The plant will use German technology, which has already been successfully tried and tested internationally. The NGRC has already secured longterm import agreements for broken glass, for example raw materials and export sales agreements with glass manufacturers. This has ensured the pre-booking of the capacities well in advance. Mr Mani’s presentation highlighted the importance of recycled glass being uncontaminated. Automated technology can achieve this on a consistent basis as the margin of error in the glass industry is zero. He added: “The benefits of glass recycling are many: glass can be recycled over and over and the quality must be

good with no contamination. “Recycled glass has to be colour sorted. Segregated, free of contamination for the glass remanufacture. If you have a greenish tinge coming out of contamination in the jar, then it is impossible to fill a product range like mayonnaise, which is white in colour. “You could end up having a greenish tinge, which looks like fungus and the product could end up being rejected and face a product recall from the market. Therefore, the process, the equipment and the technology that we’ve selected must be the best in the business, which it is.” �

Company profile: VRMT

The man bringing VR to glassmaking The Virtual Reality Machine Training (VRMT) booth at the recent glasstec was one of the most popular, with people queuing to enter the stand late into the last day. Greg Morris spoke to the company’s co-founder Tony Pawinski, who discusses how he hopes VR can transform IS operator training. early version and agreed access to its factory while Tony and Mark agreed to develop the NNPB process to mirror Beatson’s needs. Beatson Clark has remained a pivotal customer and a case study of its experiences with the VR is provided below. After several meetings with British Glass the UK association declared an interest in the project. In February 2018 VRMT was formed with Tony, Mark and British Glass’s commercial arm, Glass Technology Services (GTS), as shareholders. A news story about the technology attracted a record amount of hits to the Glass International social media site. At the recent glasstec event delegates were still queuing to use the technology on the last day of the show.

The concept The aim of the company is to digitise IS training globally. VRMT has used Oculus Rift to view the hot end in a virtual manner. The aim is to give companies a training tool that can be used to demonstrate general principles in Health and Safety around an IS machine as well as training new staff. The system is also targeted at experienced operators who can benefit from a ‘train the trainer’ principle. The system is being constantly updated thanks to feedback from Tony’s industry contacts. “I can only give Mark credit for his programming skills, each week I saw it I was impressed by something. An example is the ability to cut the machine in half to provide the wow factor. It allows the complexity of bottle manufacturing to be demonstrated in a unique manner. “At first he didn’t think he could do it but he

he lightbulb moment came at the glasstec event in 2016. While working at the trade show, Tony Pawinski saw the power of Virtual Reality and how delegates reacted to it. It immediately struck him how important the technology could be for a glassmaker and for IS training in particular. “I saw the response, and straight away it was obvious that this could be something for a glassworks. “It was clear this type of technology had huge potential especially for IS education. “Having worked all my life in a glass factory at every level, it was clear how hugely helpful it would be to train people in a safe environment and allow them to understand the glass process.” Tony personally had no previous experience of VR but had worked on various projects with a freelance design engineer, Mark Henshaw, for the past 20 years. Mark had never seen an IS machine before but, in Tony’s opinion, he was a world class design engineer capable of producing the work required for the various disciplines required for VR coding. In March 2017 the pair set about building an IS machine in the virtual world. Tony supplied drawings, videos and used his array of contacts from more than 32 years in the glass industry to provide Mark with the intricate details of an IS machine. “We spent a long time ensuring that all the actual movements of an IS machine were independent so that we could eventually make the application function like the real thing,” Tony said. In December 2017, Rotherham, UK-based container glassmaker Beatson Clark bought an

worked and worked on it and then a few weeks later at one of our weekly meetings he had done it.” The machine originally just had one section but has now increased to three sections and an independent training section. The VR programme allows an operator to do a mixture of walking and teleporting to other areas of the factory such as the lehr and feeder. Such has been the interest that the ‘plant’ now includes five Tiama machines, after the pair secured funding from the French inspection company to display its branding. Some of the functions available are the ability to swab one or all of the sections against a recordable training course. It also included the Blow Bow and NNPB processes and has the ability to split the section in half. Up to four people anywhere in the world can use the system at any one time - an important feature for glassworks with several sites.

an apprentice engineer for the UK’s Allied Glass in 1980. He worked for the container glassmaker for 32 years and in that time worked his way up to the become Head of Engineering. He worked on a variety of projects around the globe, which included project engineering in the cold end, furnace installations and IS machine installations. “I have a lot to thank Allied for. It was thanks to them that I travelled around the world buying machinery and gained an awful lot of knowledge about glassmaking. I have got nothing but respect for them and they have been a major part of me understanding all aspects of glass bottle plants. They have played a major part in my life and I made a lot of friends there.” The company also enabled him to gain a Bachelor of Engineering degree with first class honours in Electronic Engineering from Leeds Metropolitan University at the age of 50, eight years ago. As time wore on he decided he wanted a lifestyle change and to enjoy more time with wife Heather and the five children they have had between them. After a short spell working for Asmech Systems he took on a consultancy role for Leeds-based Talos Packaging, a company which provides bespoke machinery for glassworks. “I worked with Mark on a simple Virtual Reality application to promote a machine at glasstec for Talos. With my industry knowledge and Mark’s passion and experience for design and coding VR, we decided to try and re-create a working IS machine. Working at a glass plant has given me the understanding of how difficult it is to teach engineers and production staff in the art of glassmaking in a safe and standardised forum.” The decision to leave Allied and to take more control of his life has been the right one. “I love my working life now. The glass industry people are a unique bunch and I feel I have a chance to make a mark, that I’ve got something that the industry will use forever. “Everyone who has seen it so far has gone ‘wow’. That’s a great feeling. “While Mark and I have driven this to where it is, glass people have reinforced the idea, they’ll suggest things and I’ll go and discuss it with other people in the industry. It’s right to build up a picture of what the industry wants rather than just one person’s picture. “I genuinely believe we have a tool to set standards in the industry. Traditionally, the industry would lose a person’s glassmaking knowledge on the day they retired. There are people who have worked for years in the industry who have and can put their ideas into this machine, so their ideas will live on forever. “This is an opportunity to digitise people’s knowledge, which will improve the glass industry’s efficiency as a whole.” �

Case study: Beatson Clark

� Beatson Clark employee Karen Scholey using the VR training system.

Beatson Clark has been using the equipment to train new recruits to operate IS production machines. The UK container glassmaker has been working with VRMT to develop a training system to help staff understand more about the glassmaking process. Trevor Phillips, Production and Engineering Director at Beatson Clark, discusses how it was used by his colleague, Karen Scholey, a buyer at the glassmaker. “I was interested to see how quickly someone could learn, from having no knowledge of the forming process at all to being able to explain how it works without any help. Karen Scholey, our buyer, volunteered. “Firstly I showed her our real single-section training machine and various pieces of mould equipment. I then asked Karen questions about the section and found that she could not remember what we had talked about. “Then she went onto the virtual machine and I took her through the programme so that she could actually see the forming process. I then slowed the section down to a quarter of its normal speed and talked her through what was happening. “We spent 45 minutes on the VR machine, after which Karen could write down what was happening step by step. She also explained when re-heat times started and ended and could quite easily identify each piece of mould equipment. “A week later I asked Karen to take me through the process again, which she did with ease. She said that she simply visualised the section again, like recalling a film or TV programme she had watched, and she could still explain what was happening and why.”

Environment glasstec review: Excelsius

Excelsius unveils Robur Roosh German hot services group Excelsius collaborated with parent company Robur to unveil a new logo at glasstec. Sheena Adesilu spoke to senior executives.


xcelsius, the German hot services specialist, has collaborated with the Robur group to create a new logo, the Robur Roosh. This new corporate identity is a symbol of Excelsius and the group itself. It represents safety of service, quality, dedication and partnership. Frank Schwarzenau, Managing Director at Excelsius, said: “The new look is to show our customers that Excelsius is getting stronger, more in demand on the market, receiving a lot of backing from the Robur group and that Excelsius is not standing alone. We will be in the position to serve our clients as they are used to be served.” Robur aims to increase the potential of Excelsius, while still maintaining the same service. With the industrial services provider behind it, Excelsius is now part of a group, instead of existing as a small company on its own. Excelsius will maintain the same business ethic, but with it will now be able to grow and expand. Excelsius and Robur both believe that the partnership will be beneficial. Daniel Beringer, Managing Partner at Robur, said: “Throughout the group, it was a consensus of opinion that a logo required renewal to represent more of a group appearance. It was decided that, instead of making a logo change, we would rather consider that it was an award of a Roosh or a stamp of approval from the Robur group that they purchased good quality companies. “So the Roosh and the R added to our name is a stamp to say that the company is good enough to be in our group. Because we buy what we perceive to be good quality and effective middle-standing companies, which is why we took a shine to Excelsius and went through the process of buying it. I think that Excelsius is a very good company. We recognise that this would be of value to the company to give it the stamp of approval, rather than enforce a logo.” It was a six-month process to choose the logo. The decision was made one

year ago after Excelsius joined the Robur group. The final decision of the new look, the Roosh, required many discussions and revisions. The logo was changed because the Robur group is made up of 16 companies with different logo designs and looks. Both companies wanted to

show the outside world that the Robur group was united. It was necessary to make a change so that the logo of each Robur group partner looked the same. Mr Schwarzenau continued: “It was clear that the group needed to make some changes. With 16 companies and every company looking different, it did not reflect that the companies were part of one group. “So the 16 companies in the group have worked together to produce a package to define synergies, such as clients, sites and services and personnel within the group. In order to show that personnel from different group companies working at the same locations would be identified as being from the same group, the look of each needed to be changed. Following the change it is clear that each group company remains an individual company, but with a unified identity.” Excelsius aims to grow within the glass market with the support of Robur, as well as to increase its service and maintain its excellent quality. Mr Beringer continued: “We aquired Excelsius because it is a good quality company. Furthermore with our strategy being to seek out the best of high end specialist companies we found Excelsius fitted the bill for what we wanted. “What we’re buying is good companies that can provide good, different types of services to people. It was a good message to send to people internally, that there was an expectation for each other to be seen as partners – to break down barriers between all the companies in the group and bring them all into a unified look which they can share.” �

Environment Smart manufacturing

The role of partnerships on the road to smart plant success Mark Ziegler* discusses the recent collaboration between Heye International and Bucher Emhart Glass.


he fully automated manufacturing plant has become an important longterm objective for the international glass container industry. Although several technology suppliers are targeting individual initiatives, Heye International and Bucher Emhart Glass see the importance and challenge of future digitisation and automation solutions and therefore decided to collaborate in selected technical areas. Bucher Emhart and Heye share the same beliefs about the value of supplier partnerships, contending that a fully automated plant is only possible when suppliers work together. Both companies offer solutions for hot end and cold end operations and are expected to lead the process of integration within the plant. Information management is a key element of their respective initiatives. Both companies recognise the need for data integration, which is relevant from two different perspectives: (1) Total data integration in the entire value chain from manufacturer to consumer and (2) data integration to manage the automated manufacturing process. By placing a unique identifier on the container, the glass plant, brand owner and even the consumer have access to all data relating to manufacturing conditions and quality data of each food or drink container, including further treatment through transport to shelf. As a result, full traceability becomes

a reality. For high value products in particular, this is already a demand but it is quite possible that mass products will also come up with this demand too. For all products, counterfeiting can be reduced and marketing campaigns are possible.

A second important target is to improve and automate processes within the glass manufacturing process itself, delivering the vertical integration of information at a single facility. Combining all relevant plant information, including hot end, cold end and quality data, will open opportunities for process guidance, process control and automation, which is currently unthinkable. At the end, there will be an enormous gain in quality and process efficiency. The transparency of all quality data will be another benefit for manufacturer and filler. Both companies hold a number of patents, relevant to the development and implementation of important solutions on the road to the smart, fully automated glass plant. They agree that the only

way to reach important milestones on the smart road is via collaboration. Nevertheless, Heye and Bucher Emhart are continuing to market their solutions independently. A recent development is an agreement to share one of the most important patents in the field of data integration and production process automation. Under the terms of this agreement, Heye International grants Bucher Emhart Glass a royalty for its patent EP 2 114 834 B1, which secures the possibility to attach all production information and inspection results to an individual glass container and to return this information to the forming process. This patent permits the automatic adjustment of IS machines based on container-specific data, irrespective of whether this information is generated at the hot end or at the cold end or at the laboratory. Fully automated, complete container tracking solutions, the base for a glass container production process, are now close to becoming a reality. Dirk PÜrtner, President of Heye International and Martin Jetter, President of Bucher Emhart Glass are convinced of their companies’ ability to offer a wide range of new automation solutions for the smart glass plant of the future. �

The 42nd edition of the annual Asian Federation of Glass Manufacturers glass conference took place at Sheraton Mustika Yogyakarta in Indonesia. Sheena Adesilu reports. through with tariffs on $200 billion of Chinese imports, which were proposed in July. In Thai, we say, ‘let them fight or the end dies.’ But I believe, glass people will not die, because it can be recycled. I hope that you will have a good time during the conference.” Senior executives were introduced at the opening ceremony including: Harris Hendraka, the Chairman of the Organising Committee of the 42nd AFGM Conference; Worawit Sureesarakorn, the Secretary General of AFGM; Chai Kungfee, the Chairman of the Glass Manufacturers Associations of Malaysia; Emmanuel Alcantara, the Chairman of the Glass Manufacturers Federation of the Philippines; Chartchai Panichewa, the Chairman of the Glass Manufacturers Federation of Thai Industry and Tran Quoc Thai, the Chairman of the Vietnam Glass Association.

Indonesian Glass Manufacturers Association Henry Susanto, the Chairman of the Indonesian Glass Manufacturers Association, said: “The glass industry in Indonesia, as is many other manufacturing sectors, is facing a hard time. High-energy prices, competition from other countries and other types of materials and protectionism are some of the challenges that the industry is facing. “But I believe, that the glass industry will keep on growing and prosper. Glass is good for the future, as it doesn’t leave environmental damages or pollution. The theme of the 42nd Asean Glass Conference is ‘The Colourful World of Glass’. The glass world is colourful, big and lively. Glass is a material that we use in daily activities. From the mobile Continued>>


ore than 220 people attended this year’s AFGM conference, which was held in Yogyakarta, Indonesia and hosted by The Indonesia Glass Manufacturers Association (IGMA). This year’s theme was ‘The Colourful World of Glass: Shaping the Future and Breakthroughs to Excellence.’ The four-day event included a technical conference, an opening ceremony full of razzmatazz, and plenty of networking opportunities. AFGM Chairman, Mr Viwat Supatham, told the opening ceremony: “It is another year of reunion of glass people from around the world. It is in traditional AFGM history that we have been united. Even today we are all in a time of change or disruptive change. The current trade war between the USA and China is putting pressure on the world economy. It is uncertain whether the USA will follow

phone screen that we carry everyday, to containers and bottles, to the glass windows in the houses and offices we live and work in.” “Let us walk together to make this glass world grow even bigger and stronger. To achieve this, glass experts will need to create a new sense of application of glass, on top of creating stronger and lighter glass. This includes creating easy transported and safer glass to store any type of material. The industry also needs to find ways to reduce the cost of processing and manufacturing the product. Let us walk together to show that glass is the best material to use in all kinds of industries, by the glass industry and the public.” The current trade war between the USA and China is putting pressure on the world economy. The tensions among two of the biggest world economies have created a ‘challenging peril’. Protectionism is growing, which means that the main flow of goods into the international market is creating high inflation and slowing workload. A lot of countries are suffering from region to region. Mr Susanto hopes that the dispute can finally be solved for mutual benefit. However, this trade war does not affect the economy of South East Asia as much as the other regions of the world.

rating for the ease of doing business, Indonesia’s world rank has improved from 91 in 2016 to 72 in 2017 among 190 countries. This makes Indonesia recognised as one of the top markets, positioned above India, Brazil and the Philippines.” Based on the global competitiveness records of 2017-2018, Indonesia’s competitiveness index is under the world rank of 36 among 137 countries or at least from 31 in 2016-2017. To make an investment in Indonesia effective, the government also offers various discount incentives such as tax holiday, tax allowance and import duty extension. Tax holiday is valid for eight types of industries and glass investment between five to 15 years. Tax allowance and tax export addresses industries with a practical workforce. In addition, the import duty facility addresses the needs of imported machines, equipment and production. In July 2018, the government launched an online single submission system to simplify the licensing process by synchronising the licensing permits. Mr Dwiwahjono continued: “South East Asia has evolved from an agricultural society to one of the fastest growing regions in the world within the span of a century. One of the main drivers of its

growth is low-cost manufacturing. Its cheap export has provided the region with the necessary income to develop rapidly. However, in the past two decades, the world has seen the meteoritic rise of China as a manufacturing giant. You would struggle to find any boots that were not made in China. The aim is to maintain our position as a low-cost manufacturing plant.” The Asia-Pacific region accounts for more than 50% of global demand. The region is also expected to see the fastest change throughout 2018, as it benefits from the presence of the three fastest growing nations in the world. This includes Indonesia, Thailand and Vietnam. This will increase the amount of glass in Asia, creating more highrise buildings and modern architecture in the region. The current installation capacity of 10 million tonnes per year will be insufficient in the next few years. This will be the ultimate goal for the glass industry within the region: to protect its market by increasing capacity and improving efficiency. In the first segment of the 2018, Indonesia’s national economy grew 5.3%. Among all sectors, manufacturing remains the key sector of the Asian economy, which contributes to approximately 20% to national GDP. Mr Dwiwahjono concluded: “South East Asia needs to look at regional technology related to Industry 4.0. It will lead us to the current era that we are living in. The technology associated with it often includes Artificial Intelligence, block chain, quantum computing, biotechnology and more. “Indonesia, the largest economy in South East Asia, has embraced the Industry 4.0 transformation, by announcing the policy of making Industry 4.0 a priority to implement a number of strategies and Continued>>

Mr Dwiwahjono said: “The Department of Indonesia has been actively promoting economic policy as an effort to pave the way for new investments. This includes the economic techniques, simplification of processes and in particular, business licensing. Based on the latest biannual

train the new generation. To achieve this goal, this collaborative step needs to involve holistic orders. This includes the harmonistic region association of industry, academics and regional partnership. I certainly hope that we can gain more perspectives in order to move the glass industry into digitalisation and move forwards. “Together, we can open the global market to the whole picture of our glass industry.”

Prof. John Parker

Hot stuff Prof John Parker discusses various ways radioactivity has been used in the glass industry.


ne way to convert minerals to an amorphous state is by radiation damage. This process occurs naturally and gives so-called metamict products. A little damage only causes local effects, but ultimately radiation can destroy the mineral’s regular crystalline structure. Zircon minerals, where the zirconium ions may be partially substituted by uranium or thorium, often display this effect and can become completely amorphous. An amorphous state is not strictly synonymous with the glassy state in that the products do not necessarily show a glass transition from solid to liquid on heating. Nevertheless, this process is often quoted as an example of a natural event creating glass. A popular type of glassware in the late 19th and early 20th century was Vaseline Glass. One of its characteristics was its translucency, a result of deliberately induced microcrystallinity; which gave rise to weak light scattering and the name linked the appearance of the glass to that of a well-known petroleum product. Their characteristic colour was a yellowish green caused by adding uranium as the colouring agent. Uranium was allegedly used by the Romans to make yellow glasses and pitchblende ores (uraniumrich) was used by Bohemian glassmakers to colour glass in the Middle Ages, which were unearthed by silver miners in the Czech Republic. The uranium content makes these glasses radioactive and a Geiger counter may confirm the pedigree of antique Vaseline Glasses although radioactivity levels are low. However, a much better diagnosis is to check for the intense greenish fluorescence, which is created under (black) UV light. Their popularity with collectors is no doubt in part because they are now only produced by a few specialist manufacturers. Uranium is a heavy element with the

atomic number of 92 - it’s 20 times more abundant in the earth’s crust than silver. Its complex electronic structure results in multiple oxidation states of up to 6+ and a rich absorption spectrum, giving doped glasses their characteristic colours and accounts for their fluorescence. Normally it dissolves in glass in the 3+ state although other oxidation states giving different colours have been stabilised and used, particularly by the ceramics industry for their glazes. Another application of radioactive elements in the glass industry in the first half of the 20th century was to determine the flow pattern of glass through the furnace by measuring residence times. The batch would be spiked with a known quantity of a radioactive material and the time it took to travel through the furnace was measured by the radioactivity of the resulting glass. Such experiments showed that the furnace neither gave a plug flow with all the radioactivity reappearing after a single time, nor was it a perfect mixer with an immediate response which then slowly decayed over time. Rather a complex distribution of residence times was found with an average residence time of around a day, but with some glass short-circuiting through the system to give a residence time of six to eight hours. Such experiments were used to validate early model studies of flow patterns. Another application in melting technology was the use of radiation for glass level monitoring in the forehearth. A radioactive source of gamma rays such as Co60 was placed on one side of a forehearth with a detector opposite it. This radiation was partially absorbed by the refractories but enough was transmitted to be measurable. The radiation reaching the detector was influenced by the quantity of glass in its path and therefore it offered a sensitive

method of measuring glass level, vital for the control of gob weight. Such methods have been overtaken by other approaches in recent decades because of: the high costs of replacing the radioactive sources and their disposal after use; the expensive detector systems; and the precautions that had to be in place to prevent a risk of exposure to personnel. Indeed radioactivity is normally frowned upon because of its damaging effect on human tissue but this issue has been turned on its head to provide a means of destroying cancerous tissues. Prof Delbert Day from the USA has developed radioactive glass beads only microns in diameter to treat patients with inoperable liver cancer. At more than 200 sites globally, affected patients are having such beads injected into the main arteries leading to their livers, which destroy unwanted malignant cells without damaging healthy ones. Glass is also coming to the aid of the nuclear industry by providing a solution to waste disposal. An appropriate mix of glass formers is added to active solid wastes which can be melted at moderate temperatures and cast into steel containers to trap the radioactive elements in ‘solution’. These glasses, typically based on borosilicates, must dissolve large quantities of multicomponent waste and be stable over many millennia. They are buried in selected deep mines where geologists expect dry conditions to be maintained. Metamictisation is not expected as an issue, since they are already glassy! �

Technical Topics

John Henderson Henderson Technology

Lighting Glass John Henderson discusses how lighting in glass has changed over the centuries to become more efficient.


have previously written on the subject of glass used in lighting in 2013 and 2016. These articles considered the glass in the general context of lighting with reference to some specific light sources. Many would consider lighting glass as a niche market now and looked at comparatively with the sales of containers, flat glass and glass fibres/wool it would be a hard argument to refute. Glass has been used in association with light from early in its discovery and certainly as a protection for a light source as soon as it could be manipulated into shapes with some translucency and transparency. Oil and kerosene (paraffin) lamps preceded gas mantle lamps, which in turn preceded electric lamps. Recent energy efficiency legislation has seen the virtual demise of the incandescent lamp and the next target is a halogen lamp. However, it would seem that lighting glass is not dead yet as some market reports are assessing the global penetration of LED based lighting into traditional markets as approaching 60% by 2020. The figures are only projections based on historical data and assumptions about growth and value but it would seem that a revolution, arguably equivalent to that of the incandescent lamp in the early 1900’s, is taking place. Why does this impact on more traditional lighting glass? The poor energy efficiency of the standard incandescent lamp prompted significant research at the end of the 19th century and throughout the 20th into improved light sources and this gave us the fluorescent and compact fluorescent, quartz halogen, low and high

pressure sodium, mercury vapour and others. Although better than incandescent to varying degrees all these other sources had drawbacks that made it difficult for them to fully penetrate all the markets that incandescent lamps had. The development of LED’s and in particular those which gave a white light without a high heat output gave an impetus to their use in mainstream lighting markets. LED’s do generate some heat and need a heat dissipation system to counteract premature aging and to stop them burning out but the combination of colour temperature controlled white light (although the colour rendering index is not as good as halogen or incandescent) and more than 100 lumens per watt has seen their use grow exponentially. Recent technical advances are now reporting over 200 lumens per watt and potentially 300 lumens per watt, showing that the future for LED’s looks bright (pardon the rather obvious pun). One of the most attractive but functional forms of LED lighting is a glass envelope with a simulated filament inside it made up of LED sources. This change is seen in the consumer, commercial and industrial sectors and the key element for the glass industry is the use of a glass envelope or reflector in the lamp assembly. There is a real potential for growth for those glassmakers who have the capability to manufacture hollow glass, press the ubiquitous 50mm parabolic reflector or draw tubing as all these forms are used to protect the ‘filament’ in modern commercial LED lighting.

Many LED lights are packaged in translucent plastic but they generally do not have the 360o light output of glass packaged ones. Also the trend to have decorative light bulbs, some mimicking some of the original Edison designs and some being polyhedron based designs, with lower colour temperature output (orange – red) rely on the prefect transparency of glass to allow the ‘filaments’ to be visible. What constitutes a lighting glass? For most general incandescent lighting a basic soda lime silica glass was good enough for the protective envelope with a typical expansion coefficient of 95 and a soda content of 15 to 17% depending on whether it was for machine or hand manufacture. A vital characteristic for the lamp maker was the electrical resistivity, which had to be high enough to cope with mains voltages at the high temperatures these lamps ran at. The resistivity was usually boosted by having around 1% potash in the glass as part of the alkali content. The glass that carried the leads and filament would have to have a higher electrical resistivity as it was directly in contact with the wires so a 30% lead glass of about 92 expansions was used. Fortunately LED lamps do not run anywhere as hot as incandescent lamps so more basic soda lime silica glasses can be used for the components (and, dare I say it, some use plastic!) �
