Joy of work

“HAPPINESS IS A STATE where a person does not hanker after the past nor expect things to be better in the future but is happy with what he or she has right now.” This is how “happiness professor” Markku Ojanen described happiness in the Helsingin Sanomat newspaper last year. I’m sure none of you is surprised to hear that enjoying your work and being happy when working increases productivity. We think this is such an important topic that we decided to dedicate this issue of The Bridge to happiness at work. In the upper secondary school my mind was mainly occupied by topics not fit to print in the current #metoo atmosphere, or trying to figure out how to score beer while underage, but it was also the time I took my first steps towards a working career under the influence of John Grisham’s books. Grisham broke through with a number of novels idolising young professionals dedicated to their careers. Excessively long working days seemed something worth striving for, promising automatic earthly wealth. Money was the measure of success. Money was happiness. Well, I have learned the hard way that life does not always pan out like in books, which actually is a good thing, as Grisham’s books *spoiler* rarely have a happy ending. Whilst visiting Mietoinen, I talked about the subject with Maarit, our laboratory technician. She crystallised it all by saying “I have been here for almost forty years now. I think that means I have been enjoying my work.” There is endless potential in joy of work. If you are happy, it tends to make other people happy as well. It is not only about quality or improved performance. When you are happy, you talk about your work more freely. And when you talk about things, the information conveyed creates new ideas and innovations. We spend more than half of our awake time working or travelling to or from work. –

Life is surely easier if you enjoy that time.

You do not need to be any kind of a professor to understand that work plays a big role in all the feeling of happiness experienced between 8:00 am and 4:00 pm. And it is not all down to the salary; there are many small things. Some of them you do not come to think about right away. According to a recent study reported by The Telegraph, a 20 minute increase in commute time is as bad as a 19 per cent pay cut for job satisfaction. Things that feel meaningless have a negative effect on satisfaction. Needless work sucks. Therefore, you might think, it must be rewarding to do important things, right? Let us stop here for a moment.

We can definitely say that there is a good vibe in Chemigate. It is a precious and essential resource for us, difficult to define and fragile, even. I have tried to figure out ways to develop it further, both on my own and with various groups. Let us now get back to the conclusion presented in the previous paragraph about how it is rewarding to do important things. It is not always self-evident to us what it is that is so critically important in our own work. The great gurus talk about work that is in line with strategy. Galunic and Hermreck reveal in Harvard Business Review that the strategy is best accepted in companies where senior managers themselves go through the strategy with the personnel. In other words, the role of the company’s top management is even more significant than that of the immediate supervisors. This is how we do things at Chemigate, but there is surely still room for improvement. In any case, management always has a major role when talking about job satisfaction. In the words of the famed management guru Peter Drucker: “A bad manager can take a good staff and destroy it, causing the best employees to flee and the remainder to lose all motivation.” Let this be a reminder of the responsibility bestowed on all supervisors, one that might be larger than it would appear at first glance. We also wish that this issue of our magazine will bring happiness and joy to its readers.

POWERPARK (established in 2000)

VISITORS: 400,000–500,000 a year

BACKGROUND: In the middle of the plains of Finnish Ostrobothnia stands the extraordinary PowerPark, one of the biggest stars in the rural travel business. Here, local entrepreneurship has made unbelievable visions come true. The amusement park is the brainchild of one man, Jorma Lillbacka, who envisioned it based on ideas from his trips around the world.

DISTANCES TO POWERPARK:: Chemigate, Lapua 35 km Seinäjoki 55 km Vaasa 76 km Tampere 230 km Oulu 282 km Kuopio 335 km Turku 390 km Helsinki 404 km In the summer, you can get to PowerPark by train. The train stops at the Alahärmä station with a bus connection to the amusement park.

4 CHEMIGATE THE BRIDGE 2018

OPENING HOURS: The opening of the park will be celebrated on the last Saturday of April 2018. The park is open to visitors on certain days in May and every day from the 2nd of June to the 12th August 2018. After that, the park will be open on Saturdays until the 1st September, the date of the celebration of the end of the season.


FAMOUS RIDES: Ranked as the 10th best wooden roller coaster in the world, Thunderbird is PowerPark’s pride and favourite year after year. It offers an incredibly smooth ride through the tight bends and up- and downhills. Junker offers the wildest roller coaster ride in Northern Europe. It accelerates the riders from 0 to 100 km/h in only 1.9 seconds. Compare that to an F1 car, for which it takes more than two seconds to reach the same speed.

“Responsibility is essential

– we encourage our suppliers to develop” When forest industry company UPM selects suppliers, there are many criteria to be met. According to Petri Riihinen, who works in Paper Raw Material Sourcing, factors relating to responsibility are essential, since long-term success is created by means of responsible and ethical practices. Suppliers are part of the value chain UPM has more than 25,000 suppliers worldwide. All suppliers are part of UPM’s value chain, as purchasing plays a significant role in ensuring the efficiency and profitability of operations. UPM purchases various products, materials and services. Examples of these are the company’s main raw materials, such as wood, pulp, energy and recycled paper, as well as other direct and indirect material acquisitions, e.g. chemicals supplied by Chemigate. – “Chemigate is an important supplier for us in Finland. The business relationship is based on persistent and constructive collaboration,” says Petri Riihinen from UPM. Riihinen works in Paper Raw Material Sourcing as the Category Manager in Binders. He works together with suppliers from Finland, the rest of Europe, Asia, China and the US, among others. Having worked for UPM for seven years, Riihinen says that the longest supplier relationships have lasted several decades. – “UPM signs long-term partnership agreements with its key suppliers based on mutual commitment and openness. The secret of smooth collaboration is always trust between people,” Riihinen sums it up.

Extensive responsibility activities are now required from companies The UPM Supplier and Third Party Code defines the minimum level of performance that UPM requires from all of its suppliers and third party intermediaries. UPM assesses suppliers using clearly defined selection and monitoring processes: strategic suitability, service selection, product and service quality and availability as well as sustainable

operations are important criteria when selecting and assessing suppliers. UPM’s most critical terms and conditions for suppliers have to do with responsibility. – “We believe that responsible and ethical practices create long-term value for both UPM and its stakeholders. UPM has

recorded its commitment to integrity in its Code of Conduct. Our leading principle is that we do not compromise our standards of integrity under any circumstances, and we expect the same from our suppliers and third party intermediaries.” Riihinen points out that responsibility includes a lot more today than it did 10–20


years ago. For example, occupational safety, anti-corruption issues and work conditions are stipulated by law. – “The requirement level has clearly gone up. We have been forced to turn down suppliers due to responsibility issues even on larger scale. A significant proportion of suppliers in the world belong to those that we cannot use.”

”The requirement level has clearly gone up”, says Petri Riihinen.

Supplier relationships involve constant development UPM makes global and, if necessary, supplier-specific assessments of the social, financial and environmental risks involved in the company’s operations. On the basis of risk assessments and deficiencies observed, the company conducts supplier audits, for instance. When a deviation is detected in the chain, UPM requires the supplier to take corrective measures and commit to improving the situation. Deficiencies can also be dealt with using UPM’s development plan. – “The purpose of the development plan is to take the supplier to a better level. This is common and normal – we have yet to see a supplier with no room for development. It is always possible to do things better, and this also applies to us at UPM,” Riihinen says. If a supplier does not commit to developing its operations or correcting its deficiencies, the supplier relationship has to be terminated.

– “Sometimes, the operating environment or companies’ priorities change so much that we can’t continue the relationship. This happens every once in a while. A handful of relationships are terminated every year.”

Providing added value will be increasingly important The purchase process and the buyer’s role have changed in recent years. Riihinen says that while the key focus of the paper business has been on costs and capital management, he believes that the role of suppliers will be highlighted in providing added value, in particular. – “There was a time when everyone was only interested in quality and availability. Today, we are looking for technologies to reduce the overall costs and find new opportunities to add value,” Riihinen says. For example, replacing plastics is something for which new technologies are needed and sought, now and in the future. ®

”UPM has recorded its commitment to integrity in its Code of Conduct. Our leading principle is that we do not compromise our standards of integrity under any circumstances.” A good supplier …provides and delivers solutions to meet the client’s needs. For example, technologies. …follows an efficient operating model. This guarantees quality, availability and commercial competitiveness. …relies on long-term operating principles. The philosophy of continuous improvement: responsibility, ethical principles and safety ensure staff commitment, thereby securing the future.

FiberLaboratory and Chemigate find each other In the heart of Savonia, Savonlinna, just a stone’s throw away from the historic Olavinlinna Castle, is FiberLaboratory, a research unit of South-Eastern Finland University of Applied Sciences (XAMK). The unit conducts research related to paper and pulp manufacture, future forest biorefineries and environmental technology processes. In addition, FiberLaboratory offers laboratory- and factory-scale test run operations for actors in the field.

From the outset, FIBERLABORATORY has studied the wet-end chemistry of paper machines, particularly concentrating on chemical feeding and mixing in co-operation with equipment manufacturers, paper manufacturers and chemical suppliers. Several successful research projects have been carried out in this field. Starch is a chemical that has always played a key role in these projects, and related research was given a boost about four years ago when we started collaborating more closely with Chemigate. Chemigate took part in FiberLaboratory’s Reaktek research project, which aimed to make the use of conventional chemicals more efficient and determine how process conditions and chemical dosing locations can be used to adjust and optimise the distribution of materials in products. A key part in this is played by the flash mixing technology developed by Wetend Technologies, which enables the dosing of chemicals very close to web formation. The project involved developing laboratory technology that would better correspond to practical plant processes in terms

of hydrodynamic forces to which chemicals are subjected and the mixing of chemicals. With the development of test equipment, we studied the effect of the above factors on the action of starch, for example. Some observations made during the project (see the figures): - Current laboratory equipment cannot produce shear forces as great as those occurring in practice in feeding chemicals and process equipment, especially pressure screens. - The starch dosing location and shear forces in feed have a significant impact on the action of the chemical. Figure 2 shows a comparison of the effects of the starch dosing location and the chemical feeding equipment, i.e. hydrodynamics, on retention. In laboratory tests, the injection speed of chemicals could be increased with new equipment solutions, bringing the situation closer to practice. The dosing solutions had a clear effect on the retention generated by starch. The research and development work continues in a new research project called Pure, which also involves Chemigate. The

Pure project is based on the requirements that quick and efficient mixing processes place on pure and reactive raw materials. In addition to corresponding mixing conditions, a significant improvement in this is the continuous starch cooking equipment purchased for FiberLaboratory, thanks to which starch can be cooked in conditions closer to factory conditions. This is particularly essential when comparing the functionality of various starch qualities. Together, FiberLaboratory and Chemigate want to investigate the interaction of chemicals and problems relating to the use of starch and make the use of starch products more efficient. In addition, laboratory conditions are further developed to bring them closer to practice. In addition to basic research, the test facilities developed are also utilised in service research, meaning that FiberLaboratory can be contacted to order tests concerning the functionality of chemicals used in short circulation. The laboratory also has special equipment for studying the action of chemicals. ÂŽ

Chemigate’s Joni Väärikkälä creates chainsaw art

There might be a bear living inside that tree Nature’s own aesthetics and charm may inspire many kinds of creativity. Living in Mynämäki, Finland, Joni Väärikkälä finds inspiration for his art in trees. There may be a bear living in some trees and a forest bird in others. Joni’s creative tool is not a painter’s brush but rather a chainsaw.

Joni has been carving wood for over 20 years. “On my journeys around Lapland, I saw a wide variety of wood art and was inspired to try it out myself. Using a chainsaw felt natural, as I live on a large farm and I am accustomed to cutting firewood.” Joni says that his sculptures are often inspired by the shape of each piece of wood. “I guess I see a character inside the wood. The piece of wood itself has a great influence – its shape and form provide a framework for the sculpture.” Joni has been working at the Chemigate´s Mietoinen plant since 1986, and he worked in Raisio before that. His positions have included those of a process operator and shift supervisor. With his partial retirement at the beginning of the year, he now has more time for chainsaw art.

Hundreds of sculptures

Wood sculptures are often inspired by the shape of the piece of wood to be carved. All in all, Joni Väärikkälä has created hundreds of sculptures in the past 20 years.

Joni says that he learned the skill through practice. “At the beginning, I sketched some models on paper, but this is really about learning through trial and error. I no longer sketch anything in advance. All my work shows my style of doing things.” Joni always uses a chainsaw for creating his wood sculptures, and their colouring is a combination of controlled burning and tar. The sizes of the sculptures vary from a few dozen centimetres to about two metres. Joni uses various kinds of saws, the smallest of which has a special carving blade that can be used for smaller details. “Sculpting a bear usually starts from the head by first sawing the general shape. When I sculpt a bird, I usually start by narrowing the piece of wood to get the shape right. Birds also need to be filed a bit during the finishing stage, but bears or other larger sculptures do not require tools other than the saw.” While the majority of the sculptures are created using spruce wood, aspen has also proved to be a good material. “It is fairly soft and doesn’t necessarily crack as badly as spruce.” In the course of his career, Joni has made hundreds of sculptures. Some of them have been specially commissioned. “Sculpting a bear may easily take a couple of days, depending on the size. Larger sculptures make it necessary to use scaffolding, which increases the degree of difficulty. With the help of a crane I can lift quite large pieces of wood.” ®

Sustainable competitiveness Promoting sustainable development involves taking care of the sufficiency of natural resources, the environment and the well-being of people. It shows in all our operations, bringing sustainable competitiveness for both us and our customers.

Chemigate provides its customers with products originating from nature. Starchbased products, such as binding agents and coatings for the paper industry, are an ecologically sustainable option for replacing oil-based raw materials. “We are also a member of the Chemical Industry Federation of Finland and develop our responsibility on the basis of shared goals. We want to act as part of our customers’ responsible delivery chain,” says Chemigate’s product safety expert Raija Savolainen. Common areas of responsibility in the chemical industry include the sustainable use of natural resources, safety of production and products, occupational well-being

and transparent communications to interest groups. Companies in the field systematically work to promote responsibility by taking part in the Responsible Care programme.

Responsible functionality Chemigate bears responsibility for its production chain by taking sustainable operations and production safety into account right from the product development stage. In the paper and board industry, Chemigate’s modified starch-based products have several positive environmental impacts. The carbon footprint of bio-based polymers is much smaller than that of synthetic polymers.

Chemigate’s starch-based water treatment products replace synthetic flocculants and inorganic coagulants in wastewater and sludge treatment. At the wet end, cationic starches efficiently adhere to anionic fibres, thereby significantly reducing the wastewater loads and energy consumption of paper machines. The process is boosted and raw material efficiency improved by liquid cationic, anionic and amphoteric fixatives, runnability and strength polymers. In coating, starch is also increasingly replacing synthetic chemical products.

Purely Finnish and responsibly international The starch production chain is a good example of the chemical industry’s circular economy and bioeconomy, where the processes are efficient in terms of materials and friendly to the environment. Chemigate’s modern dry modification plant in Lapua enables modified starch production with a significantly lower energy consumption and wastewater volume than the wet modification process. What comes to Chemigate’s main raw materials, native barley and potato starches are sourced directly from domestic partners. Indeed, they are clearly among the best on the market in terms of purity and responsibility. Thousands of Finnish farmers are employed in growing barley and starch potatoes. Native wheat starch is purchased from several different sources, all of them responsible European suppliers.

Chemigate goes through its responsible operating model together with every supplier.

14 CHEMIGATE THE BRIDGE 2018

Before making a native starch sourcing decision, Chemigate goes through its responsible operating model together with the supplier. If something needs to be improved, we will do this together. This is always the case, regardless of whether we are dealing with Finnish barley or Thai tapioca.

Towards a more responsible future Responsibility is part of modern business, and reporting obligations have increased in large corporations in particular. Many companies are reporting environmental, human rights, human resources and interest group issues relevant to their operations as well as their ethical practices. “Chemigate is also increasingly being contacted for details concerning our operations, raw materials and products that help our customers verify and develop responsibility in their production chains,”

Raija Savolainen says. Last year, we received queries from 23 different customer companies regarding PSR (product safety and regulation) issues, but we were also more and more often asked about quality, sustainable development and responsibility issues and their management. In total, Chemigate sent out about 130 responses. Recently, Chemigate has especially invested in development of safety onsite.. Safety training has been provided on production sites, and employees are encouraged to actively develop the work environment and practices in an even safer direction. A resource assessment performed some time ago also resulted in establishing a completely new QEHS position. One nice example of occupational well-being is Chemigate’s traditional Maineteko award, which is given out three times a year, allowing all Chemigate employees to nominate colleagues who deserve recognition for positive actions, expertise or promoting good team spirit. ®

We conducted a quick poll among Chemigate employees on their coffee break and, as you might have guessed, happiness at work is a personal experience. We all experience it! It is when you immerse yourself in your work so that you achieve the flow state. You forget that you are working. It happens to me every day. I have nice colleagues and interesting assignments. Kati

You need to feel that you are doing something important. I often work alone in the laboratory, so all social contacts during the day matter to me. Therefore, I was happily surprised to discover that my colleagues had prepared me a birthday card with a Kismet chocolate bar in it. Maarit

You must take care of business, but not be too serious about it. Happiness at work gives you strength. When you work in the same place for a long time, your appreciation of your colleagues and also customer relationships may evolve into something deeper, even friendship. Elise

To be happy at work, you need a happy and relaxed atmosphere as well as humour. I love to go to work. Things like a successful test run of a new product, for example, bring a smile to my face. Jani

It means that I’m happy to go to work in the morning. Variety of work is important so that you do not get stuck in routines. Humour brings joy every day; I like to hear good stories. Juha

Softer tissue for your tabletops and skin

Soft but strong Softness and strength are the two main attributes in tissue paper that a consumer finds desirable. Unfortunately, these two are, to a degree, mutually exclusive. The way producers tackle the dilemma is that they set the strength to an adequate level and then maximise softness. However, whatever gets you away from this balancing act, i.e. whatever you can do to increase softness without losing strength, is worth the effort What makes the task of increasing softness more complex is that the perception of softness in itself is difficult to define. What humans consider softness is a mix of physical and sensory properties as well as what our brains have previously learnt to associate with something soft. Softness and strength can be influenced by a number of factors and operations on and before the paper machine.

16 CHEMIGATE THE BRIDGE 2018

• Choice of fibres Whether the tissue is made from virgin or recycled fibres impacts strength as well as what the softwood to hardwood ratio in the virgin pulp is. • Layering of fibres Two- to three-layer headboxes are common in the tissue industry. Both the number of plies and the plies in which hardwood is used have an impact on softness. It makes sense for the producer to have the soft ply on the surface and the ply with the strength potential on the inside. • Formation Bad formation has a negative impact on strength. • Creping While creping is essential for most tissue because of what it does to softness, it does break hydrogen bonds and thus has a poor impact on strength. • Chemical softeners While these are easy to use for adding softness, they typically do not add strength.

The solution is PrimeBOND PrimeBOND products are multifunctional starch-based polymers designed to improve both process runnability and end product quality. They improve properties like retention, drainage, formation, strength, bulk and dusting. PrimeBOND is supplied as ready-to-use liquid. A major part of the work done by Chemigate in tissue relates to improvement of softness. Many of our customers define the softness target, and we focus on it together by optimising different parameters and using PrimeBOND. PrimeBOND gives us the possibility to improve softness by increasing mechanical strength parameters. By adding PrimeBOND, we have the possibility to increase softness by: - Adjusting the ratio of softwood in pulp - The reduction of refining energy - The replacement of other non-elastic chemical additives (PAM, PEI, CMC, etc.) ®

In shape Around the time you read this magazine, we will already know which workplace team has worked the most actively this spring to keep in shape. This year, the fifth exercise campaign organised by Chemigate for its personnel and interest groups involves 16 teams – a total of about 150 active people. The competition originally pre-dates Chemigate, dating back to 2000. That year, Raisio Chemicals and Rhodia established a joint venture, Latexia, and the amount of work shot through the roof. As the number of sick days started increasing and time spent exercising was on the decline, people around a coffee table on the second floor of the chemicals building decided to start activating each other. An Excel spreadsheet was printed out and put on the table, requiring everyone to exercise at least twice a week and at least half an hour at a time. The threshold was suitably low in order for the challenge to start working, and after some initial grumbling, the entire floor was actively involved. Good ideas tend to grow. Before long, the concept started gaining popularity around other coffee tables. Challenges were thrown around, and eventually partners outside the company also started asking what the exercise campaign was all about. In its current form, the campaign has become an eagerly anticipated part of Chemigate’s occupational well-being activities each spring and is also supported and sponsored by the management. – “Our goal is to encourage everyone to exercise a bit more and slightly more regularly,” says Maisa Kantola, Chemigate’s Marketing & Product Manager, who is the primus motor of the campaign. “We are particularly delighted to have people getting involved who have not been exercising regularly before.”

– “The campaign is built on joy, playfulness and voluntariness. The competition between the teams and the slight peer pressure involved provide an additional boost and strengthen self-discipline. The progress made, or the number of exercises performed, can now also be followed directly online.” People have even started asking about the competition every year. There are true stories about changed lifestyles and increased well-being, team spirit and happiness at work. ®

The happy horn blower

Have you heard about a birch bark horn that changes owners at the darkest time of the year and bears the engraved names of all its previous holders? Unlike many other legends, this story is true. It is a company tradition at Chemigate in which the horn is ceremoniously handed over to the new owner by the previous holder. The recipient of the horn is jointly decided by the three previous holders, often for some specific merit. However, the decision may also involve a slight irony, which is not necessarily even voiced. This year, the fine piece of handicraft adorns my own desk. For me, it is a source of joy and pride, recognition for myself and my work. The birch bark horn has been passed around Chemigate ever since the company was established. Chemigate received the horn upon its separation from BASF in 2010. However, the item itself is much older, seeing that it currently bears the names of 21 holders. So, the horn dates back to more than 20 years ago. It is said that the tradition started at Raisio Chemicals’ Christmas lunch in

20 CHEMIGATE THE BRIDGE 2018

1997, when the management team assembled in a private room at the Marina hotel and ran into an itinerant handicraft seller.

“Communicator of the Year” As usual at Christmas time, events and achievements of the past year were vividly discussed. It emerged that a member of the management team had, on the quiet and all my himself, created a Two Horn Blowers rather hefty environmental report for the company. Even though the report was good and highly useful, the managing director at the time must have been slightly annoyed by not having known what his subordinate was up to. And since he did not want to complain publicly, he ingeniously named his

subordinate “Communicator of the Year” and gave him the birch bark horn he had just purchased from the artisan as a symbolic gesture. Initially, the horn was probably just a joke. It only became a tradition after being

reincarnated. Rumour has it that this particular “Horn Blower of the Year” had earlier promised his wife that he would clean about four kilos of Baltic herring – as was customary for the family before Christmas – immediately after returning home. Right

PAPER RECEIPTS – FORGET THEM!

after lunch, that is. According to a normal or even slightly extended lunch practice, this probably means around 3 pm, and his wife must also have had something like this in mind. But it is sometimes difficult to estimate the time, especially when you are having fun. And when you have received a special award for your work, even if it was meant to be a bit ironic, you simply have to celebrate the occasion.

So, it must have been getting late when the happy horn blower arrived home, where his wife was “eagerly” expecting him. He proudly presented his wife with his new instrument and the good news. Apparently, she was not quite as impressed, and the waiting had made her tired and not so empathetic. She grabbed the horn, knocked him on the head with it and retorted, “No reason to blow your horn now.” As the reader can probably deduce from this, the instrument on my desk is not exactly the original one. When the story of the original horn’s fate got around, the managing director said that it had naturally been meant as an annually awarded trophy. And since finding a similar horn proved slightly challenging before the rise of the Internet, the trophy was awarded as a virtual version the following year. The more concrete reincarnation took place about a year later. After being passed around the ranks of Raisio Chemicals, Ciba and BASF, the horn finally found its way home and now annually adorns the desk of a merited Chemigate employee. ®

Petit Fours

Visit by biotechnology students

Kati Haapaniemi started at Chemigate Lapua

Some merry representatives from the Bioner student organization (technology students from the Tampere University of Technology) visited Chemigate on a frigid March Tuesday. They were acquainted with Chemigate’s production and product portfolio as well as with the local pizza. Since modern students are used to a demanding and competitive environment we decided to organize a test for them. The winners were Samuli, Matias, Vili and Olga. Congratulations!

Kati Haapaniemi started working for Chemigate Oy at the beginning of January. She acts as a substitute for Tuire during Tuire’s maternity and care leave until the end of 2019 and beyond, if necessary. Kati will work at the Lapua site, and her main area of responsibility is to take care of the order desk. Kati has worked for the company previously during the summers of 2012 and 2013, performing similar tasks. In her spare time, Kati studies economics at the University of Vaasa.

Audits by SCA and Saint-Gobain Shaoxia Wang – top specialist as a trainee 36-year-old Shaoxia Wang, DSc (Tech), started a six-month trainee period at Chemigate late last year. Born in China, Shaoxia studied at Åbo Akademi, completing the degrees of MSc (Tech) and DSc (Tech). Shaoxia specialises in the surface properties of paper and their characterisation. At Chemigate, Shaoxia is mainly involved in projects related to grain starch chemistry and analytics.

Various interest groups visited our production plants last year. We particularly welcome audits by customers. In addition to indicating an interest in our operations, they signal an opportunity for longerterm collaboration. All the feedback we receive from audits is valuable and helps us to develop further. Customers who visited our Lapua plant for an audit included SCA and Saint-Gobain. Pictured are some key persons from Saint-Gobain’s central purchasing unit and Kirkkonummi gypsum board plant.

Tom and Mikko – 100 years of life experience

Getting to know Finnamyl’s potato flour mill

More experience (and years!). This year will see the 50th birthday of Tom Lundin (18 March 2018) and Mikko Nieminen (24 November 2018) from Chemigate’s sales team. Chemigate congratulates both of them! Can you believe they are turning 50?

Chemigate’s Mietoinen unit started its Christmas party last year by visiting Finnamyl Ltd’s Kokemäki potato flour mill, which provides some of the raw material used by Chemigate. Even though the mill was part of the same company throughout the Raisio years, not everyone was familiar with the place. With excellent guidance by Production Manager Tauno Henttinen, this was soon remedied and the visitors became familiarised with the mill and its processes.

30th anniversary of the Mietoinen cationization plant Chemigate’s cationization chemical production plant in Mietoinen had its 30th anniversary in 2016. This occasion was celebrated in March 2018, “slightly late”, during an ice hockey game between TPS and HIFK. By the way, did you know that Raisio Group’s first steps in the chemical business were originally taken in Mietoinen? Mietoinen hosted an old dairy building where the first paper latex products were manufactured in 1971. Later on, several other products for the paper industry, such as AKD sizes, were produced on the same premises.
