working toward a food waste solution
We must commit
ourselves to take action on source reduction and food rescue and recovery, at all stages of the food supply chain.”
César Rafael Chávez
ith all the current focus on scrap import restrictions in China, as well as NAFTA negotiations between the U.S. and Canada which could have long-term effects on trade in steel, aluminum and a range of other goods and commodities, it is easy to forget about some of the other ongoing challenges affecting the recycling and waste management sector. This past spring, the Commission for Environmental Cooperation (CEC), based out of Montreal, released a comprehensive report on the state of food loss and waste in Canada, Mexico and the United States, developed through the CEC’s North American Initiative on Food Waste Reduction and Recovery. “Characterization and Management of Food Loss and Waste in North America” documents the adverse socioeconomic and environmental impacts of food loss and waste, and actions that the industrial, commercial, institutional, government and nongovernmental sectors can implement to mitigate these impacts. The report estimates that 168 million tonnes of food are wasted in North America each year, with Americans wasting 415 kilograms (915 pounds) per capita, Canadians 396 kilograms (873 pounds) per capita, and Mexicans 249 kilograms (549 pounds) per capita. With notable differences between the three countries, the report finds that the largest share of food loss and waste in North America – 67 million tonnes/ year – occurs at the consumer level. In addition, there are 52 million tonnes wasted at the industrial, commercial and institutional levels and 49 million
tonnes at the pre-harvest level. This loss of food waste represents a huge waste of social, economic and natural resources and has significant environmental impacts. The CEC report also provides an examination of the primary causes of the problem, focusing on overproduction, product damage, lack of standardized date labelling practices, lack of coldchain infrastructure, rigid food-grading specifications, and varying customer demand and market fluctuations. According to César Rafael Chávez, CEC executive director, “As we build a greater understanding about the impact of food loss and waste on our economy and environment, we must also commit ourselves to take action on source reduction and food rescue and recovery, at all stages of the food supply chain. “Our aim with this report is to establish a baseline and identify an array of tools and strategies that will enable each sector of the food supply chain to make reducing these losses a reality.” Distributors, retailers, food-rescue organizations and food service providers have a critical role to play in realizing solutions to the issue of food waste loss. As do recyclers. For those that recognize the fact that when it comes to food waste, there is a neverending supply of material, there is high demand for end product, and the technology and systems for its conversion to compost and energy is available and advancing rapidly a massive opportunity awaits.

UPFRONT MRF News
New mixed residential waste, single-stream MRF to manage growing tonnage in York, South Carolina Machinex has been awarded the bid to provide a new single-stream material recovery system for York County, South Carolina, which is planned to be operational as of July. This new system will allow the County to process the growing tonnage of residential recycling materials being generated in the surrounding area. Material is sourced from 16 collection and recycling centres located throughout the County, all of which will be processed at the new facility. The new MRF is designed to handle 10,000 to 15,000 tons per year of mixed single-stream materials, coming primarily from residential sources, with a limited amount from commercial generators. It features equipment including a Machinex MACH double-deck OCC screen designed to reduce wrapping and improve cardboard recovery, as well as a fines screen installed at the beginning of the process. A Machinex MACH Ballistic Separator was also installed, instead of a traditional disc screen, to separate fibre from contain-
Bandit Industries shifts to 100 percent employee ownership Bandit Industries owners Mike Morey Sr., Dianne Morey and Jerry Morey announced in June that they would sell 100 percent of the company to their employees in an employee stock ownership plan (ESOP). Under the ESOP, Bandit will retain its current leadership and key management personnel will remain in place. The announcement comes after two previous attempts to sell Bandit Industries – once to another manufacturer and once to a private investment firm. “We realized neither was a good fit for Bandit, so we made the decision to sell to our trusted employees,” said Dianne Morey. “It will be fun to watch our crew take it to the next level,” said Mike Morey Sr., who developed the very first Bandit chipper in 1983 and founded Bandit Industries. 10 Recycling Product News July/August 2018
ers. In addition, the facility’s new automated container-sorting line includes a PET optical sorter, a magnet and an eddy current separator. Finally, a Machinex II-ram baler was selected to complete the system. “The Machinex project management team did a great job of keeping the project moving along, and our interaction with their crews was excellent,” said Arthur Ligon, York County Government. “The startup personnel did a very good job training us on the system and helping our staff with all of the operational aspects.” “The County has been processing all of the recyclables collected from their 16 collection and recycling centres at a dual-stream facility that utilized nearly all manual labour,” said Rusty Angel, eastern region sales manager at Machinex. “We applaud the County for having the vision to build this new single-stream facility to process their material for many years to come. Machinex will be a great partner to help them meet the demands of their rapidly growing population.” Used oil recycling
Terrapure wins second Environmental Leader Award for used oil management For the second consecutive year, Terrapure Environmental has received an Environmental Leader Award for Product of the Year for its innovative circular-economy approach to managing used lubricating oil. The award was announced on May 16, 2018, at the Environmental Leader & Energy Manager Conference in Denver, Colorado. Terrapure collects used oil from various industries. Through its patented re-refining process, the company transforms waste oil into premium-quality base oils and lubricants. Terrapure’s North Vancouver facility (right) is the world’s first commercial-scale re-refinery
to use vacuum distillation and hydro-treating to recover base oil from used lubricating oil. The Environmental Leader Awards recognize excellence in products, services and projects that add significant value to energy, environmental and sustainability management efforts. Winners are awarded based on scores from a panel of distinguished judges with extensive experience in environmental management. “We see the value in waste and aim to recover as much of that value as possible,” said Ryan Reid, executive vice president of resource recovery, Terrapure Environmental. “Our oil recycling services pro-

vide a closed-loop solution for lubricants. We transform waste oil into valuable new base oils while preventing potentially hazardous used oil from entering and harming the natural environment.” Each year, Terrapure says they produce 32 million litres of new re-refined base oils and lubricants, which are virtually indistinguishable from those made from virgin crude oil. They are used in place of or in conjunction with virgin base oils. This not only avoids the need for over 10 million barrels of virgin crude oil, but also produces base oil with a significantly lower greenhouse gas intensity than that of traditional crude refining.
The Canadian Plastics Industry Association (CPIA) and the Chemistry Industry Association of Canada (CIAC) recently announced ambitious targets that underscore their members’ commitment to a future without plastic waste. Representing the broad plastics value chain in Canada, CPIA and CIAC and their members announced the following waste reduction targets: • A new aspirational goal of 100 percent of plastics packaging being reused, recycled, or recovered by 2040. • An aggressive interim goal of 100 percent of plastics packaging being recyclable or recoverable by 2030. “Plastics innovations are essential to increase living standards and improve overall sustainability via new products that design out waste, reduce food waste, support resource efficiency, conserve water and natural resources and reduce emissions,” said Carol Hochu, President and CEO of CPIA. “But it is a waste of precious resources for plastics to be used once and then landfilled.” Hochu adds that achieving the above goals will require significant investment across the value chain in new and upgraded infrastructure and improved packaging design. Success will also require widespread public participation in recycling and recovery programs along with changes to littering behaviour. “Industry has a role to play in designing materials and applications for greater recovery, reuse and recyclability, but addressing the issue of plastic waste will require actions from society as a whole and from all of us as individuals,” said Bob Masterson, President and CEO of CIAC. These aggressive targets put the Canadian plastics industry in line with PlasticsEurope and the American Chemistry Council, organizations which recently announced similar ambitions.

ISRI advocacy delivers on latest tariff measures
Hauling & Collection News
Autocar Trucks first to introduce new Cummins X12 engine to refuse market Autocar Trucks will be the first truck manufacturer to offer the new Cummins X12 engine to customers serving the refuse and recyclables industry. The X12 12-litre diesel engine has remarkably reduced weight, enabling haulers to handle more material and simultaneously lower their operating costs. Autocar will begin accepting orders in June for X12-powered ACX trucks, to be produced in October of this year, immediately after Cummins begins full U.S. production of the X12. Autocar will offer the X12 across all Class 8 severe-duty vocational applications. “Autocar is focused on bringing innovations to the market with real, tangible benefits to our customers,” said Jim Johnston, president of Autocar. “This new engine puts more cash in our customers’ pockets, plain and simple. We’re gratified that Cummins trusts us to bring the X12 engine to the refuse market first.”
According to Autocar, the new X12 engine outperforms all competitors from 11 to 13 litres due to its high power density. Haulers with the Autocar ACX and X12 engine will see a significant weight savings, compared to the previous 12-litre engine, with more payload available. The weight savings is achieved through an innovative sculpted block design, as well as weight reduction in the aftertreatment system, power takeoff and other components. The X12 also offers improved low-speed torque with similar horsepower ratings. Autocar says their integration of the X12 will also lower operating costs due to extended maintenance intervals, 25 percent fewer parts, and a six percent improvement in fuel economy due to enhanced engine efficiency and reduction of parasitic loss. The fuel savings alone equates to $10,800 over the life of a typical collection truck, at current diesel prices, according to Autocar.
12 Recycling Product News July/August 2018
As China and the U.S. continue to spar back and forth with new tariffs being imposed on key imports and goods, in mid-June the Trump Administration announced a final list of products from China that would be assessed a 25 percent import duty. Several key equipment parts imported from China for use in recycling operations were included on the initial list but were removed after pressure from the Institute of Scrap Recycling Industries (ISRI). The products which ended up not having tariffs imposed include some categories of electromechanical appliances, parts of trash compactors, flexible permanent magnets, electromagnetic couplings, clutches and brakes. ISRI also noted that because magnets are made from rare earth elements, the vast majority of which is mined in China, the recycling industry is dependent on Chinese sources for the majority of magnets required. “We are in the midst of global uncertainty when it comes to trade policies impacting the recycling industry,” said Robin Wiener, president of ISRI. “As policy changes continue to develop at a very fast pace, ISRI remains vigilant in advocating for recyclers and keeping members up to date on the most recent trade developments.” In comments to the Office of the U.S. Trade Representatives in May 2018, ISRI wrote: “In some cases, such as in auto shredding operations, shredder parts must be replaced daily. For most companies, such equipment turnover makes up a large percentage of their operating costs. “The vast majority of these parts – up 85 percent for crush and grind parts, for example – are supplied from China. Adding a 25 percent import tariff on these parts would irreparably harm the competitiveness of the U.S. recycling industry and risk recycling and manufacturing jobs due to lower output and thus, few inputs to metal production and fewer exports of recyclable materials.”

New consortium says Canada has opportunity to lead global change on plastics recycling Canadian plastics recycling veterans and entrepreneurs Tony Moucachen and Emmie Leung (right) have combined the significant market presence of their three extended plastics processing and recycling companies – Merlin Plastics Group, ReVital Polymers and Emterra Group – to launch North America's largest plastics recycling consortium – Circular Polymers Group (CPG). According to the new consortium, Canada has an opportunity to lead global change on how plastics are valued, used, recovered, reused and recycled, and the solutions are available domestically. In 2017, this group, which operates a
combined 38 multi-materials handling and recycling facilities in Canada and the U.S., collected and recycled well over 136 million kilograms of plastics from residential curbside recycling systems, beverage container deposit-return systems and the industrial, commercial and institutional (IC&I) sectors. This recycling activity is backed by $300 million of installed capital and supports 1,500 jobs that drive a growing circular economy for plastics. “While each of our companies will continue to do business individually, we’ll be working synergistically to offer our customers the combined knowledge of 75 years of recycling expertise, state-
of-the-art technology and solutionsoriented, strategic thinking,” said Tony Moucachen. “Circular Polymers Group is a consortium company that is truly greater than the sum of its parts.”

CARI names new chair
RePower South partners with BHS on wasteto-fuel revamp; SWANA awards Penn Waste South Carolina-based RePower South (RPS) has reached an agreement with the City of Montgomery, Alabama, to operate the City’s state-ofthe-art MRF. RPS will invest $12 million in the newly named City of Montgomery Recycling and Recovery Facility. RPS has partnered with Bulk Handling Systems (BHS) and Loesche Energy Systems to revamp the existing recycling system to also produce a low-carbon renewable fuel that will be sold to industry, cement and utility customers to replace coal in their production processes. The system will process 45 tons per hour of mixed waste to capture cardboard, metals, paper and plastics and produce fuel. New equipment joining the existing BHS screen, Nihot air and NRT optical sorting technologies, will include a primary reducer, two NRT optical sorters for fuel cleanup, a Loesche fuel system reducer and PAAL Dokon baler. In total, the system features 10 optical sorters, ensuring positive recovery of fibre and containers and removal of contamination from fuel. Also recently announced, the Solid Waste Association of North America (SWANA) has named Penn Waste as winner of the SWANA Silver Excellence Award in the Recycling Systems category. The award will be presented at the association’s annual conference, WASTECON, on August 22 in Nashville, Tennessee. Penn Waste is receiving the award for its York, Pennsylvania, 45-tph single-stream system retrofit (shown above). The 2017 retrofit, provided by BHS, boosted capacity 130 percent to 45 tons per hour. It also added NRT optical sorting technology and a Max-AI AQC robotic sorter (Autonomous Quality Control) to improve container recovery and purity. These improvements resulted in a facility with the capability to process 18,000 tons per month with more than 98 percent uptime and capturing 98 percent of recyclables. Penn Waste says that the company did not lose a single ton during the speedy retrofit and has since been running at 100 percent capacity with lower operating costs.

Materials Recovery for the Future research program to pilot curbside recycling of flexible plastic packaging The Materials Recovery for the Future (MRFF) research program, has entered into a new partnership with J.P. Mascaro & Sons to pilot single-stream curbside recycling of flexible plastic packaging (FPP) at its TotalRecycle materials recovery facility in Berks County, Pennsylvania. This will be the first pilot to demonstrate the technical and economic feasibility of recycling household FPP from municipal residential singlestream recycling programs. The MRFF collaborative consists of various large corporations involved in plastics product manufacturing, as well as plastics recycling industry associations and other stakeholders. “Our MRFF collaborative is excited to partner with J.P. Mascaro and demonstrate the recyclability of flexible plastic packaging,” said Steve Sikra, MRFF chairperson and associate director of global research and development for Procter & Gamble. “We are all committed to the success of this program and look forward to adding recycled flexible packaging into the circular economy.” FPP – which includes films,wraps, bags and pouches – is not widely recycled currently. This pilot is expected to generate data to help inform municipalities and the recycling industry on the most efficient and economical ways to recycle FPP, including converting used FPP materials into a bale that can be sold to a variety of end markets. According to Resource Recycling Systems (RRS) the recycling system consultancy which
conducts the MRFF research program, 12 billion pounds of FPP material is introduced into the market for consumer use every year, and it is the fastest growing form of packaging. RRS estimates TotalRecycle will produce 3,100 tons/year of highquality post-consumer FPP feedstock for various end-market uses that are being tested. Van Dyk Recycling Solutions is the equipment supplier on this project, and will be adding sorting equipment to Mascaro’s TotalRecycle facility that will target FPP out of the singlestream flow. The FPP will be identified and separated by advanced optical sorters, resulting in a new generation bale of FPP. The pilot program, scheduled for two years, will begin in late 2018 with the installation of the sorting equipment. After an initial testing period, TotalRecycle will begin accepting FPP for recycling from the municipal residents it serves. C
SWANA provides update on impact of China’s waste import restrictions In mid-June, the Solid Waste Association of North America (SWANA) issued an update for state and provincial environmental agencies on China’s waste import restrictions and their impact on recycling programs in North America. This update, the third in a series to agencies on the issue, provides an overview of the effect that the restrictions are having on the export of recyclables from the U.S. and Canada, including the increased movement of material to Southeast Asian countries and additional potential restrictions. “The deepening impact of China’s waste import restrictions is being felt in a growing number of communities,” said David Biderman, SWANA’s Executive Director and CEO. “In addition to the ban on certain materials and the
16 Recycling Product News July/August 2018
new stringent contamination standard, China temporarily halted pre-shipment inspections in May. Combined with new limitations by other Asian countries receiving more recyclables from the U.S., the result has been lower prices and continued uncertainty about the long-term sustainability of recycling programs. SWANA feels it is important to continue to update key stakeholders on this evolving situation.” SWANA has established a Recycling Task Force consisting of industry and municipal leaders and has led advocacy on Capitol Hill for recycling-related funding in the infrastructure bill. They also consult with associations and other organizations that support recycling and they have developed a China Waste Import Restrictions webpage of resources.
“For the past several decades, China has served as the end market for roughly a third of the world’s recyclables, and its new policy banning mixed plastics and mixed paper has created a global oversupply of paper on the world market,” said Susan Robinson, director of federal affairs for Waste Management and member of SWANA’s Recycling Task Force. “This supply and demand imbalance, combined with China’s new 0.5 percent contamination standard, has increased the quality requirements for recyclables, whether they are moving to domestic markets or to other alternative markets. Until new markets develop, stakeholders will need to work together to develop solutions that will support our local recycling programs.”

rail cars, barges and ship applications. The operating weight for the 850 M is 134,200 pounds (60,873 kg) while the R-HD unit on crawler tracks weighs in at approximately 146,300 pounds (66,360 kg). The 850 can also be fitted with one of several boom and stick configurations, providing a maximum reach of up to 69 feet (21 m). The new 850 E is also among the first models to feature the latest version of Sennebogen’s popular Maxcab operator station, designed to be longer and roomier than its previous iterations, and features joystick travel controls, eliminating the steering wheel, to ensure an unobstructed forward line of site. Dual cameras for rear and right-side visibility are also provided, and with innovative full-guarding on the upper deck, the 850 E provides a safe platform for technicians. As on previous Maxcab designs, the new version includes a sliding door and a catwalk with handrail for added safety.

New ThermoPRO granulators for thermoforming
Rapid Granulator has introduced a new range of granulators designed specifically for in-line processing of skeletal waste from sheet and film thermoforming lines. The new patent-pending ThermoPRO Series is available in various standard and low-built formats for handling scrap widths from 600 to 1,500 mm (24 to 60 inches) ThermoPRO machines combine features already proven on other Rapid granulators, including double-scissor cutting action, an “open hearted” design for fast production changeovers and ease of maintenance, a mineral composite base for high stability and low noise, with numerous other new elements that were tailormade to make thermoforming operations easier to run and more cost-effective. “Thermoforming companies live or die according to how well they handle and recycle their trim,” said Bengt Rimark, Rapid’s CEO based in Bredaryd, Sweden. “Skeletal waste can easily account for up to 30 to 40 percent of total throughput, so it is critical that the trimmed material is returned to the process as costeffectively as possible and with the highest quality possible. The savings that the converter can make are enormous.”

Morbark introduces 6400XT horizontal grinder Morbark, LLC recently debuted two new machines: the 6400XT Wood Hog Horizontal Grinder (shown here) along with a new 50/48X Whole Tree Drum Chipper. “Morbark listened closely to customers when we developed both the 6400XT Wood Hog and the 50/48X Drum Chipper,” said Michael Stanton, Morbark Director of Industrial Sales. “We took our previous proven design technology and added the features our customers want and the versatility they need when we created these highproduction units.” “The Model 6400XT is the newest model in Morbark’s next-generation platform of horizontal grinders,” said Stanton. “Industry demands for high-production mobile units that meet stringent logistic restrictions but remain economically viable were the leading drivers during the design phase.” The 6400XT includes many feature improvements present in the smaller 3400XT, introduced last year. The infeed bed is 24 inches (60.96 cm) longer than previous Morbark grinders in the 1,000-plus horsepower range and has sloped sides. This configuration improves operator sight lines for more efficient loading of material. Standard on the 6400XT is a removable infeed chain return floor, which allows excess material to fall away to minimize the wear on the floor, bed chain and inserts, particularly useful in land-clearing or other applications with dirty material. Also similar to the 3400XT is the focus on transportability. The 6400XT weighs in at less than 96,500 pounds (43,772 kg) and measures 11 feet 5-1/2 inches (3.49 m) wide with the standard Caterpillar 325L undercarriage with 600 mm double grousers, allowing the unit to be transported to nearly all domestic and international markets.

Beyond specs: The power of a machine demo
demo of Caterpillar material handler provides SA Recycling with the opportunity to be confident in their latest equipment investment by Keith Barker, Editor
On site at SA Recycling, Las Vegas, from left: David Brown, Jose Fuentes, Erasmo Hernandez and John Vega.
A Recycling operates over 70 scrap metal recycling yards in the U.S., including close to two dozen ferrous shredder operations. The company, started in Orange, California, has since grown as far north as Fresno, and east to Arizona and Texas. More recently, the company expanded to the U.S. southeast, into Alabama, Georgia and Tennessee. Originally, SA Recycling was Adams Steel; they merged with Sims about ten years ago to form “SA,” which stands for Sims-Adams. Directly following its display at ISRI 2018, held in Las Vegas in April, Caterpillar transferred their new MH3026 material handler directly from the show floor, at the Mandalay Bay Resort, to SA Recycling’s Western Yard, located in Las Vegas. The machine was there as a demo unit for one week and then moved to another SA Recycling yard in Decatur, Alabama. The company has since purchased the MH3026. While demos of this kind of heavy-duty machinery at scrapyards prior to purchase are not a common practice in the scrap recycling industry, it does happen from time to time and can be a very beneficial part of the process for buyers. Firstly, for this to happen local dealers need to have a machine available for demo purposes, which is generally not the case.
Vincent Migeotte, Caterpillar’s global product marketing and application consultant for specialty hydraulic excavators, agrees that with respect to demo units, it’s not normally common practice for dealers to have them available. But, he says this year is an exception for Caterpillar as the company realigns their line of material handlers for scrap and waste applications – specifically the models MH3024 and MH3026. “It’s important to demonstrate and document the right machine for the right application,” says Migeotte. “This is the reason why we purposely have MH3026 and MH3024 demonstration units in North America – for internal training, but also for on-site demonstration. “It helps us to document true performance of the unit at the scrapyard and in transfer stations, and have solid customer references and data from the field.” According to Frank J. Arriaga, account manager at Caterpillar, the MH3026 machine is a relatively new size for SA Recycling. “Historically, they have utilized slightly larger track machines,” says Arriaga. “After having experience with Cat’s line of MH3037, MH3049 and MH3059 material handling machines, and after learning about the specs of this new machine – the capacity of the grapple, its reach, and feaJuly/August 2018 www.recyclingproductnews.com
scrapyard equipment & operations tures including the cab riser and the fact that it’s on wheels – SA determined this model would be an excellent match for their feeder yards.” Arriaga says this is what “drove the demo” of the MH3026 for SA Recycling in Las Vegas, along with the fact that they had the unit available directly following ISRI 2018. The purpose-built MH3026 material handler features a 25,220- to 26,150-kg (55,601- to 57,651-pound) operating weight, depending on the configuration, and provides 126 kW (169 hp) net power, using a Cat C7.1 ACERT engine. “What they did in April with the demo of the MH3026, was to validate the machine for their operations,” continues Arriaga. “It is one thing to verify that all the specs look right, but it’s another thing to gauge operators in the seat and in the application, put it to work, and confirm that it will do what it needs to do.” He adds that SA Recycling is definitely no stranger to Caterpillar equipment. The two companies have a long-term relationship, built over the last decade, through Caterpillar dealers around North America, including Cashman Equipment, Quinn Company and Empire. Currently, SA Recycling operates a large number of Cat wheel loaders

During the test demo at their Western Yard, SA Recycling’s new MH3026, fitted with a one-yard Caterpillar four-tine grapple, was used primarily to unload trucks, move end-of-life vehicles, stockpile ferrous materials, and then sort and load materials for transfer to the shredder yard. and skid steers, as well as material handlers using grapples, and excavators fitted with mobile shears. “SA uses our 349 or 336 model excavators, mounted with Cat shears, to cut scrap,” explains Arriaga. “They also use Cat loaders, ranging from the 938 model all the way up to the 988, a fleet of series 262 and 246 skid steers, and they have experience with our material handling machines at their different yards.” According to Arriaga, even though SA Recycling knows Caterpillar equipment very well, any time a demo of new equipment is possible, it can be critical for the customer to have complete confidence that the specific machine is capable of completing the required tasks for their specific sites. “They can get a good understanding of the machine’s capabilities from our specifications,” he continues, “but nothing is better than actually having their operators and technicians on the machine at their site. “The demo at SA Recycling, Las Vegas, allowed them to feel comfortable with the capabilities and features
of the machine before making the final purchase decision.”
Test results tell the tale
David Brown, regional manager (Nevada) for S.A. Recycling, was the company’s lead on the April demo. In the Las Vegas region, Brown says they handle about 20,000 tons of ferrous and nonferrous scrap (including scrap autos) per month and operate one shredder. At the company’s Western Yard, on Western Avenue, Las Vegas, where they tested out the new Cat MH3026 material handler, they process about 1,500 tonnes of scrap per month. “It’s only about a four-acre yard, so we don’t need a larger machine,” says Brown. “The size of this one is perfect for that size yard. The mobility with its rubber tires, for getting around the yard, and around the pile, is great. “We had a Cat 330 excavator that had more than 30,000 hours on it,” he continues. “We needed a new machine for loading and unloading. The MH3026 is much quicker, more fuel-efficient and

Our operators appreciate the way this new machine travels around the yard, and the hydraulic system is quicker as well.” In addition, Brown says SA operators mentioned their appreciation for the MH3026 cab which, from an ergonomic perspective, is designed to be much more comfortable than cabs on previous Caterpillar machines. “Our operators also appreciated the custom-moulded seats and the joysticks, during the demo,” he says. “They liked the riser cab, and not having to climb up the crane. They were also impressed with all the MH3026 safety features, such as the extra camera on the operator’s right side. Previously, the operator’s view would be obstructed by the boom,” he said. Now, there’s a split-screen camera there so operators can see what’s on the other side of the boom. “Previously, this was a blind spot.”

It’s night and day compared to our old machine.” During the test demo at their Western Yard, the new MH3026, fitted with a one-yard Caterpillar four-tine grapple, was used primarily to unload trucks, move end-of-life vehicles, stockpile ferrous materials, and then sort and load materials for transfer to the shredder yard. “The MH3026 basically needed to handle loading and unloading for the entire ferrous side of the business at our Western Yard,” explains Brown, who

adds that it did the job very smoothly. “We also use a 1-1/2-yard grapple on the older 330 excavator,” (which is still very much in use) “but because of the way the new grapple is designed, our operators say they can grab more with the one-yard unit,” he said. Feedback received from operators during the demo was focused around the speed of the machine, as well as the safety features and comfort of the cab. According to Migeotte, top speed on the MH3026 is 12.4 mph, when the unit is
According to Migeotte, as with all Caterpillar machines, “Safety is not optional.” He says there are many safety features and devices embedded into the MH3026 to help enforce safe behaviour, in addition to the dual camera with standard split-screen. Another key safety feature, for example, is a seatbelt that has an indicator on the monitor as well as an audible alarm so that machine operation without a fastened safety belt can be reported via Product Link, Cat’s standard telematics system. “The cab will not move up or down unless the cab door is properly closed, and all our material handlers are fitted with boom and stick lowering check valves to prevent sudden front-end movement in case of hydraulic hose issues,” continues Migeotte. “Cab ingress also has been specifically well thought out on the MH3026, with three long access steps aligned with the cab entry and an additional integrated step directly below the cab door. “Also concerning cab ingress,”
Migeotte continues, “new with the 2018 edition is direct access when the upper carriage is not aligned with the chassis, through optional steps on the front and rear of the undercarriage.” With respect to safety features on the new generation of Caterpillar material handlers, Migeotte also points to antiskid plates on all walkways and steps, reducing slipping hazards, with handrails designed for three points of contact in any location on the machine, and a standard auto-lubrification system, exfactory, which also reduces the need for operators and mechanics to climb on the machine or reach to the end of the MH boom for proper lubrification. “For operator comfort, and for safety, sound levels (inside the cab and outside) have been drastically reduced on the MH3026 so that the operator can stay alert,” adds Migeotte. He additionally notes that Cat’s Product Link telematics is deeply integrated into their latest generation’s monitoring system and is specifically designed to take the guesswork out of managing the equipment. “The system tracks location, hours, fuel usage, idle time, and diagnostic codes and shares it with the site supervisor and the local dealership through VisionLink,” he says. “It helps users maximize efficiency, improve productivity, and lower operating costs, and it helps supervise safety procedures.” By having the chance to test the MH3026 material handler, before bringing it online at their Alabama yard, SA Recycling was provided with the opportunity to be confident that their investment would provide all of the safety and performance features they require. In Las Vegas, it very quickly proved to be the right fit for their feeder yards. “Demoing the latest edition of our product line allows not only the customer and operator to benefit from the latest development in production and safety features but also allows them to ensure the right size machine for the job is selected,” concludes Migeotte. “This is critical as quite often it means a reduction in ownership cost as we find out that a new model edition can do the job of a previous larger, heavier model.” RPN

Turning waste to
komptech Turners and screens key to success for one of Michigan’s largest suppliers of compost and mulch by keith barker, editor
liff Walkington is General Manager of Hammond Farms, where he’s been for 22 years. He took over from Lee Hammond Sr., whose son Lee Hammond Jr., the current assistant general manager, is now ready to take over the job. “I’ve been with the company since I was in school,” says Hammond Jr. “I was bagging product when I was ten.” According to Walkington, Lee Hammond Senior’s idea from the start was that Lansing, Michigan needed a “one-stop-shop” for all gardening products. “We never stopped developing along those lines,” he says, adding that “In the past few years organic waste has become more and more important.” Hammond Farms processes large volumes of green cuttings and compost, mixing it down to about 52,000 cubic yards of premium soil substrate, while also having products including paving and decorative stones on offer. Today the company puts out nearly 104,000 cubic yards of mulch, including 65,000 cubic yards of coloured mulch.
In addition to processing the biodegradable waste that they take in from the Lansing area, Hammond Farms needed to find the right recipe for composting an increasing amount of very damp material. “We experimented and tried out a lot of things,” Walkington says. “We used to mix the material with front loaders. That took two weeks. Now we do the same amount in three quarters of a day with a Topturn X63.” He says this investment, made at the end of 2016, has made their process much more economical. According to Kevin Yuncker, Komptech America’s representative for Hammond Farms, Komptech’s Topturn X63 is an ideal fit for their operation. “The X63 Topturn processes material in less than 10 percent of the time it takes a front end loader,” says Yuncker. “This significantly reduces labour and resources needed for compost rows and allows the operator time to take care of other projects on the yard. The X63 turns material slowly and mixes completely, while introducing oxygen into the pile. This reduces the overall time on the yard,

Walkington adds that spring is when Hammond Farms is at its busiest. Demand for all products starts to rise in late March, along with the temperature. “It peaks in late May,” he says. “Every-
thing starts to tail off after June.” Early on, he adds that large-volume customers like municipalities dominate their business, while later in the season, most sales are to individuals and home gardeners.
Screens key for Hammond farms
“At the beginning of spring we can’t make enough material,” continues Walkington. “Our two screeners run practically around the clock.” The screeners he’s talking about are star screens – a Komptech Multistar L3, and an XL3. The L3 is the older machine, with about six years at Hammond Farms, and over 5,000 operating hours under its belt.
Walkington first learned about Komptech screens at a mulch producer conference. A presentation about the benefits of star screening caught his attention. “Star screens make nice material and throughput is high,” says Walkington, adding “These screeners go far toward reducing shredding costs, because we only need to reshred the screen overflow.” After more than six years, Walkington also has nothing but praise for the relationship they have built with Komptech Americas. “If a minor problem does come up, they’re ready to listen,” he says, adding that he’s especially appreciative of his key contact person at Komptech Americas, Kevin Yuncker. Yuncker describes the model XL3 Multistar, which Hammond bought at the end of 2014, as a screen that produces a high-quality mulch from the primary grind. “The fuel consumption is less than two gallons per hour, at 300+ yards per hour, so there is a significant savings over re-grinding all of the mulch through a grinder at 40+ gallons per

hour,” explains Yuncker. “The Multistar is capable of going from a high-quality double-grind or high-quality triplegrind by pushing a button, as well as switching from 1-inch down to 3/8-inch in compost material.”
The future is green
Hammond Farms opened its fourth location at the start of 2018. The employee headcount is at 50 and there are plans to hire more. Designated successor, Lee Hammond Jr., says they are going to be marketing to areas farther away soon and expects continued growth. Still, while legal mandates are already very strict in Europe and Canada, the U.S. has barely started to regulate the composting industry. Walkington says they expect much more restrictive legislation down the road. “A few years ago five percent, by volume, of plastic was okay in finished compost,” he says. “Now it’s only one percent. And
Komptech’s Topturn X3 compost turner is designed to save time and produce a highquality product with low operating costs. we expect that to tighten up.” Of course, there is a good side to this. “More and more people are aware that to get a clean product, you need to do something about the waste at the source,” Walkington says. “We also know that we have a responsibility to educate the public. More and more schools and interested individuals come to visit us and tour
the plant,” he continues. “And that’s just the tip of the iceberg. The next generation needs to do better, and I’m sure they will.” He adds that he gets a lot of compliments from visitors. “People are really excited when they see our operation. We turn what looks like trash into a beautiful product.” You might even call it gold. RPN

wood waste: best practices
DISC SCREEN FUNDAMENTALS D By Paul JanzĂŠ
isc screens are versatile but simple machines, ideal for screening woody biomass, for recycling and waste-to-fuel applications. They provide good agitation, which is necessary for separating biomass particles that tend to knit together. They are designed to handle rocks and other large, heavy contaminants without undue damage, and are able to withstand a great deal of wear from abrasion. The disc screen consists of a series of driven shaft assemblies mounted in a frame. Each rotor shaft assembly has profiled discs mounted at regular spacings. The discs from one shaft interleave with those on the adjacent shafts, creating open areas between the discs and the shafts. In application, incoming material is fed onto one end of the screen, the shaft assemblies rotate, discs agitate the material and move it along the screen. Pieces of material that are smaller than the spacing between the discs and shaft assemblies fall through the screen, while pieces that are larger than the openings are conveyed along the top of the discs and pass over the end of the screen. Properly designed and constructed disc screens are rugged, typically running all year without major servicing. However, in case of required maintenance, the screen should be located in a system such that it can be bypassed or physically moved out of the process flow with minimal effort.
34 Recycling Product News July/August 2018
Disc Screen Sizing and Capacity
To properly size a disc screen, recyclers should consider the volume of incoming material, the material size distribution and the required product size. Disc screen capacity depends upon the percentage of screen open area, defined as the open area divided by the total screen footprint, and is a function of several factors: the number of rotor shaft assemblies; disc interface opening and slot length; disc thickness; shape of the disc screen profile; shaft/spacer collar diameter; screen width and length; and rotor speed. Disc screens should be sized such that under the maximum possible flow conditions, all the undersized material has passed through the screen with at least one to two rotors clear of the end of the screen. For width, at a minimum, disc screens should be somewhat wider than the feed conveyor. However, the most important factor for determining optimal screen width is the amount of material being delivered to the screen. For a given volume of material, a narrow screen will have a much deeper bed depth of material than will a wide screen and it will take much longer for the undersized material to percolate down through the bed. Conversely, it can be difficult to spread incoming material across the width of a wide screen. This can sometimes be done with deflector plates, but on very wide screens a distribu-
tion screw or similar device might be required. Our experience has determined an optimal nominal rotor speed of approximately 30-50 rpm for most woody biomass, depending upon disc and spacer collar outside diameters. Generally, increasing overall screen speed will increase the amount of material rejected over the end of the screen and have the effect of increasing screen capacity. Conversely, decreasing speed increases dwell time and increases the amount of material passing through the screen, but decreases capacity. Installing the screen on a slight incline or decline will also have an effect on dwell time, screening efficiency and capacity.
input and output
When handling biomass, it is generally best to have the screen in line with the feed conveyor, particularly where you have long pieces and big chunks of wood. Try to avoid turns of 90 degrees onto the screen, but if necessary, provide for extra height and a long, wide chute to prevent big pieces from jamming. Material should not drop directly on the top of the screen discs, as long thin pieces will dive straight through the screen. For infeed chutework, it should be designed to evenly spread the material across the width of the screen. Discharge chutework should be sufficiently steep such that fines will not build up in the valleys, and the screen should be high enough above the downstream equipment or a bunker to discharge with suitable chute angles. Finally, it should be noted that processing dry wood and bark through disc screens can be very dusty. Screens should be equipped with sealed covers and all components of a system, including conveyors, chutes and screens, should be properly enclosed and ventilated in order to keep a negative pressure inside the equipment, thereby minimizing fugitive dusting.

food waste management
the Dryclone Air Drying System provides energyefficient way to decrease moisture in food waste
ood waste continues to be a huge challenge in Canada, according to the March 2018 report of the Commission for Environmental Cooperation (CEC). According to the CEC report, 396 kilograms of food is lost or wasted per capita each year across the food supply chain in Canada. Longer-term solutions will need to involve legislative and behavioural changes – for industry and consumers. But what can be done about the problem right now? Food waste contains energy and nutrients, and with the right kind of
processing, it can be put to very good use. Moisture content is the biggest barrier to getting at food waste’s valuable attributes. Moisture typically makes up more than half the weight of food waste overall, adding significantly to transportation and disposal costs. Removing the moisture content will save on transportation and disposal costs and also make it easier to take advantage of the energy and nutrient content. Most of the moisture found in food waste is contained inside the cell structure. Up to now, there hasn’t been an energy-efficient way of getting rid of the moisture as conventional dryers can’t get to the moisture inside the cell structure.
The Dryclone System
Food waste can be reduced to lower than 15 percent moisture content after processing in the Dryclone Air Drying System. 36 Recycling Product News July/August 2018
The Dryclone Air Drying System, manufactured by Resource Converting, LLC (RCI), based out of Las Vegas, is engineered to remove the moisture inside the cell structure of all organic materials, including food waste. The Dryclone system (shown above) uses huge volumes of high-speed air to dry food waste and carry the moisture away, while aerodynamically pulverizing material to shear open the cell structure and remove moisture inside the cells. The Dryclone system can convert food waste with moisture content up to 75 percent, to total moisture content of 15 percent or less, depending on the characteristics of the waste. This results
in a weight reduction of between 30 and 70 percent, depending on the initial moisture content, with a corresponding reduction in transportation and disposal costs. With the moisture removed additional value can be derived from the energy and nutrition content. Once food waste has been processed in the Dryclone, it can be used in wasteto-energy processes. Food waste dried in the Dryclone has sufficient energy content to be a valuable addition to solid recovered fuel (SRF) and will also reduce overall ash percentage by weight. As an alternative output option, if food waste is separated at source and kept separate throughout the process, once it’s been processed in the Dryclone it can be used as an additive in animal feed or fertilizer. Drying food waste with the Dryclone unlocks the true potential of its energy or nutrition value, and by removing moisture content the weight of food waste is reduced significantly. This means transportation and disposal costs, including off-taker fees, will go down significantly. By using the right technology to create valuable end products, it can be cost-efficient to keep food waste out of landfills.

Breakthrough hydrolysis technology transforms food waste into organic fertilizer and biogas
n innovative Canadian technology targeting global markets has successfully completed commercial-scale processing of livestock carcass by-products into fertilizers and biogas at the Lethbridge Biogas biorefining plant. This new thermal hydrolysis and fractionation process transforms animal by-products and food waste, including inedible meat and bones, into safe, nutrient-rich products for organic fertilizer and biogas production. The new process has been certified by the Canadian Food Inspection Agency (CFIA) for the processing of Specified Risk Materials (SRM’s), and was adopted by the 178 member countries of the World Organization for Animal Health (OIE). It is approved for the destruction of all infectious microbiological pathogens and TSE agents
causing prion diseases such as BSE (Bovine Spongiform Encephalopathy) in cattle and CWD (Chronic Wasting Disease) in elk and deer. The process, which is unique in the world, utilizes high pressure and high temperature steam reactors, and provides an environmentally superior alternative to traditional rendering, incineration and landfilling of diseaserisk materials such as carcasses, while creating economic value from the hydrolyzed nutrient output materials. Names the “BIOTHYDRO” process, the new technology was invented by Dr. Erick Schmidt and was developed and privately funded by Biosphere Technologies lnc., involving scientists and engineers in Alberta and Edinburgh, Scotland, over a 20-year period. It has patent protection in over 20
countries and is designed to create two valuable streams. The process converts fractions of amino acids, fatty acids and digestible minerals into organic fertilizers, and secondly creates feedstocks for anaerobic digesters producing methane biogas. According to Biosphere Technologies, these applications will provide the emerging organic agriculture, gardening and medical marijuana sectors with needed alternatives to synthetic chemical fertilizers, and will serve regulated industrial demands for renewable natural gas and sustainable energy. Technology rights have been licensed to the Lethbridge Biogas facility, now in operation, and two other facilities. Negotiations have also commenced with agricultural groups in Europe, the U.S. and China.

and is led by co-chairs Bob Long, who is a councillor with the Township of Langley, B.C., and Lori Nikkel from Second Harvest. Key findings suggest more needs to be done to tackle food waste along the whole supply chain, to access business and marketing innovators to provide solutions to food waste, and to improve the entire food donation system. The updated Strategy, now called A Food Loss and Waste Strategy for Canada, recommends a coordinated national effort to halve food waste by 2030. A key theme of the strategy calls for a supply chain approach that would close the loop on food waste occurring during production, processing and distribution – before it even gets to consumers. “More than a third of the food Canada produces never gets eaten,” says Malcolm Brodie, Chair of the National Zero Waste Council. “Half of this waste occurs on the supply side and the rest at home. Though many food waste reduction activities are already underway, they are mostly happening in isolation from each other. We can achieve far greater success through collaboration and a unified vision for change.” The report takes into consideration the logistical challenges of Canada’s vast geography and sparse population centres, as well as the fact that most businesses involved in food production, distribution and retail operate on a relatively small scale. The report, broadly supported by a diverse range of stakeholders, recommends that the federal government actively support a national food loss and waste reduction target of 50 percent by 2030 and increased collaboration between government, businesses, retailers and community organizations. Other key recommendations include: introduction of new regulations clarifying “best before” labelling; improved inventory management at businesses and large institutions; upgraded food service tracking and distribution; removal of barriers to heighten recovery of leftover safe and nutritious food through gleaning and charitable networks; and the elimination of financial, legal and policy obstacles surrounding food donations. “This collaborative work by the National Zero Waste Council is critical in helping Canada join other global leaders in addressing food loss and waste,” says Cher Mereweather, executive director of Provision Coalition. The National Zero Waste Council also recently released new Guidelines for Food Donation in Canada and will be launching in late 2018 a national behaviour change campaign with local governments and retailers to help support change within our Canadian culture regarding food waste.

LFC Biodigester engineered to minimize disposal costs and environmental footprint
he LFC biodigester from San Jose, California-based Power Knot LLC is designed to provide on-site composting of solid food waste, automatically converting material into drain-safe waste water. Units provide odour-free operation, cut waste disposal costs, and continuous biodigestion allows food waste to be added at any time. The LFC-300 model (shown here) can digest up to 500 kg (1,200 pounds) of organic waste per day, including fruits, vegetables, raw and cooked meat, fish, cheese, bread, rice, and noodles. A range of available models offer capacities from 20 to 1,800 kg/day (45 to 4,000 pounds/day). These compact stainless steel biodigesters are intended for on-site installation at commercial or institutional food preparation and distribution facilities including restaurants, hotels, schools, supermarkets, hospitals, nursing homes, theme parks, corporations, military canteens, prisons, ships, island properties and food resellers. In the LFC biodigester, a horizontal agitator rotates slowly within a U-shaped vessel to maximize contact between solid food waste, bacteria, air, water and patented enzymes residing in porous plastic chips that remain in the vessel. The digestion process is aerobic and exothermic (it releases heat), raising the vessel temperature to about 42°C (108°F) which, along with automated infusions of hot and cold water, maximizes the rate of decomposition. Liquids resulting from biodigestion drain continuously through a screen along the bottom of the vessel, to an outlet and into any municipal drain. Since the grey water is rich in nutrients, it can also be plumbed into irrigation systems for lawns, shrubbery beds and crops. In addition, the LFC Biodigester features load cells supporting each corner. These transmit the weight of food waste, with an accuracy of ±1 percent, to a PLC which

food waste management
Freddie Mac moves toward green campus goal with JWC Monster food waste shredder
orporate campuses that house their own cafeterias need to deal with large volumes of discarded food; with that comes the challenge of how to store large volumes of bulky, heavy waste for disposal. Many corporations today are turning to volume reduction strategies using industrial shredders to cut organics to a particle size that can more efficiently be stored on site until it can be picked up. Freddie Mac, the well-known financial firm, has over 6,000 employees on the company’s campus daily. Their goal as a “green campus” was to compost around 145 tons of food annually and keep 900 tons of recycled material out of landfills annually. One of the company’s earlier programs was to institute the use of compostable to-go containers and utensils instead of plastics. The company’s manager of corporate food service & amenities, Guido Boers, noticed the high number of guests at the cafeteria dropping off their compostable used to-go containers with the remnants of lunch onto the tray return conveyor. All the debris returned was headed to the landfill instead of being diverted to composting. The bulky containers also took up massive amounts of space in dumpsters, driving up disposal costs. During an audit of Freddie Mac’s waste management procedures, it became clear to Boers and his team that something needed to be done to reduce the high volume of compostable to-go containers currently being landfilled.
the JWC Shredding Solution
After recognizing the problem of high-volume waste,
Boers and his team at Freddie Mac decided on a new strategy to shred down all the soiled containers to reduce their volume and then compost the organic debris. The challenge was finding the right piece of equipment to reduce the waste volume. “I was looking for a solution to grind up the compostable containers and I really hit a wall on what to do,” said Boers. “I had heard a little bit about JWC Environmental and knew that their grinders had been used in U.S. Navy vessels for food waste – so I figured their equipment had to be heavy-duty and reliable.” Boers reached out to JWC Environmental and was connected with Tom Smith, JWC’s National accounts manager. Smith suggested incorporating a JWC Monster Industrial 3-SHRED grinder into their waste reduction efforts to reduce the total volume. “Tom requested that we send sample containers and JWC could perform a grind test,” said Boers. “JWC ran the test at their facility and sent us a video of the results. The results were great.” Once the grinder was put in place the Freddie Mac food services group quickly saw the benefit. The 3-SHRED grinder was able to quickly reduce to-go containers to less than half the original volume. Boers now expects the kitchen to divert over 3,000 65-gallon bags of compostable materials annually from the solid waste stream. Thanks to their 3-SHRED food waste grinder, the food service program at Freddie Mac’s corporate campus is now running efficiently and has become “greener” and more productive. They met their goal of composting 145 tons of food and have kept 900 tons of recycled material out of landfills in the space of one year. This article was submitted on behalf of JWC Environmental.

efuse and recycling collection fleets are challenged every day by some of the most severe hauling environments. From residential locations to inner city streets to landfills, waste fleets must tackle challenging routes to get the job done. These harsh operating conditions can cause tires to wear more quickly which leads to frequent need for replacement; this has significant cost implications for fleets. This is where retreads come in.

est standards of quality are maintained throughout the retreading process, from buying tread rubber to getting retreads to market.
An efficient retread program starts with the right casing. Every tire casing is designed with specific performance attributes based on the application needs. Fleets need to start with a quality casing engineered with higher retreadability – one that is durable in high-scrub and short-haul environments and touts longer wear performance. Premium casings are engineered to work with quality retreads to capitalize on the unused potential of the casings once removed. Fleets which retread are simply ahead of the game. On average, refuse fleets can retread tire casings every three to six months and between two and three times per casing, which taps into extra mileage potential.
The retreading process has progressed over the last few years with the integration of advanced technology into both the inspection and product development processes. The modern retreading process

Any casing inconsistencies detected during initial inspection are repaired before a new tread is applied. After repair, the casing is retreaded through a multi-step process, which includes buffing (removal of any remaining tread) and curing of a new tread on the tire casing. Once complete, the casing is again inspected a final time before being returned to service. This proven process is robust and designed to ensure highquality retreaded tires.

Proactive maintenance and monitoring
A proper tire maintenance program is key to ensure reliable performance on the road and help prevent premature removal of tires and downtime. Refuse fleets that are proactive in their tire care best practices – consistently conducting pre- and post-trip inspections and regular yard checks, and routinely rotating tires and inspecting casings for road-related or operationally related damage – typically do a better job of caring for casings to ensure they can be retreaded in the future. Tracking performance is also critical to ensuring fleets get the most out of a tire and retread program. Fleets should look to partner with dealers that have capability to monitor and record retread performance, repair history, inventory and casing rejection information in real time. For example, Bandag’s tire management system, BASys, provides actionable insights to refuse fleets so they can make informed decisions about their tires. Knowing the integrity of casings and how many times they have been retreaded helps ensure assets are being used to their full potential and performance.
A trusted dealer network should be considered crucial in designing and maintaining a custom tire program tailored to meet the needs of a waste collection fleet. By understanding the business needs of a fleet, a dealer can ensure that the right tire is selected for the job and that a fleet’s tire assets are wellmaintained for long life and can be retreaded when needed.
The bottom line
There’s no doubt waste fleets have a unique set of tire needs to operate efficiently and profitably. Retreads can help fleets make mobility more efficient by capitalizing on tire performance potential, and by integrating technology into the retread process and proactive maintenance practices, waste and recycling fleets can be assured that retreads provide a reliable and profitable solution to get the job done.

Co-procesamiento de Tire Derived Fuel
for tdf M By Mike Hinsey, Granutech-Saturn Systems
ore than three decades into the tire recycling movement, the largest application for scrap tires remains the alternative fuels market. This is for good reason, as scrap tires are a tremendous resource of energy and iron. Major industries consuming tire-derived fuel (TDF) include cement producers, paper mills and energy utilities. To produce TDF, tires are first shredded into small chips. For cement plants, the steel is retained in the chips as it serves a useful purpose in the production of cement, reducing the volume of iron ore needed for addition into the mixture. For other fuel markets, the preference (or requirement) is for a smaller low-steel-content tire chip, since steel content can be detrimental, by reducing the energy value of TDF and causing havoc with the feed grates in the combustion unit. While TDF does not fit the traditional idea of what a biofuel is, by definition biofuels can come from “domestic and/or industrial wastes.” Numerous government and environmental studies from around the world have substantiated the energy benefits achieved with tire-derived fuel, while confirming emission levels comparable to other fossil fuels. Countries that are considered the model for environmental responsibility, such as Sweden, endorse, support and encourage the use of TDF. In April 2005, the U.S. EPA published the following statement: “Based on over 15 years of experience with more than 80 individual facilities, EPA recognizes that the use of tire-derived fuels is a viable alternative to the use of fossil fuels.” For cement plants, TDF provides an alternative fuel at a competitive cost compared to traditional fossil fuels. TDF has a higher thermal value than most forms of coal, while also containing around 15 percent iron content in the form of tire wire. TDF is supplied as a chip, achieved by shredding, grinding and screening, until meeting the required size, which is usually around 2 inches. In some cases, whole tires can be supplied to TDF producers, though there tends to be strict size requirements involved which eliminates the viability of many tires for this method of supply. For traditional energy customers, TDF with very low steel content is preferred. This is achieved through additional stages of shredding or grinding and by using magnets to separate the wire. This results in a fuel product with energy value around 14,000 BTU/ pound, about 40 percent higher than TDF with wire content. Industry has responded to the need for higher volumes of lowsteel TDF by introducing high-capacity grinders which achieve

To produce TDF, tires are first shredded, ground and screened into small chips. For some applications, steel is retained. For others, a smaller, low-steelcontent tire chip is more appropriate. steel separation much more efficiently than previously achieved simply by shredding. This increased capacity is helping to meet a demand that far exceeds supply in much of North America. Most scrap tire processors, given the choice, would much rather convert scrap tires into granulate and powder, yielding a far better return on their investment. However, the reality is that there is inadequate market demand for these granulates compared to the volume of scrap tires generated, necessitating the need in most regions to move more than 50 percent of tire volume into TDF markets. It is not simply a case of “producing the granulates and consumers will come.” One only needs to look at the province of Ontario, where there are no established markets or incentives to produce TDF. All program tires are converted to granulate, which has vastly oversupplied provincial needs, resulting in material travelling south into the U.S. where granulate oversupply and depressed prices impact tire processors in the Northeast, Great Lakes region, and areas much further south. Without TDF markets, many processors would struggle to survive. By establishing a large alternative fuel demand for TDF, scrap tires get diverted from dangerous tire piles and are kept out of landfills, while allowing processors the opportunity to make substantial investments in TDF and granulate-producing machinery.

focus on Fire safety
in the line of fire — technology’s role in
facing an epidemic
With the risks of fire increasing in the recycling and waste industry, advanced technical solutions can substantially reduce occurrence and mitigate cost of incidents
W By Ryan Fogelman
Although we have been
faced with facility fires in the waste and recycling industry for years, we are just now seeing the real extent of the problem.”
e have seen a spike in fires in the recycling industry in 2018, compared to previous years. March, April and May 2018 are now the highest months we have recorded for fire incidents at waste and recycling facilities. March 2018 could merely be an anomaly. But then came April, with 36 fires, and then May, with 38 fires reported – the highest number of fires in any month since I began reporting recycling and waste industry facility fires in 2015. There are multiple factors that are contributing to this increase. For example, there has been a large increase of lithiumion batteries into the waste stream. There has also been an increase of material stock in facilities, in part due to China’s recyclable materials import restrictions, as well as warmer/drier-than-usual weather compared to previous years. It should be noted as well that there has been an increase in reporting and public awareness of fire incidents in all industries. In the past 12 months, we have recorded 368 unique reported waste and recycling facility fire incidents in the U.S. and Canada. When you factor in my extremely conservative assumptions that we are under-reporting waste and recycling facility fires by about 5:1, we are looking at a reasonably estimated current number of fire incidents in the U.S. and Canada at approximately 1700+ yearly. In our industry, whether processing metals, plastics, waste, chemicals, C&D, paper, e-waste, rubber, organics or hazardous materials, we have numerous inherent spark-developing dangers. This includes the presence of a range of explosive and com-
48 Recycling Product News July/August 2018
bustible materials in mixed waste (hot loads), loader buckets scratching concrete, sparks from shredders and other large equipment, and large stockpiles of materials. There are things the industry can do to alleviate the risk, including improving basic housekeeping and staff/public education. We can also increase investment in the most up-to-date fire protection and suppression technology, which means going beyond the fire alarm and sprinkler.
Seasonal factors and hot loads
Seasonal factors are important to note. Since we have started tracking fire incidents at recycling facilities and scrapyards, we have recorded an increase in fire incidents during the summer’s warmer and drier months, as well as holiday spikes due to increased amount of materials being processed at the end of each calendar year. Industry expert Jim Emerson provides his theory of what can cause an increase in summertime hot loads – which are created by the mixing of a wide range of combustible and explosive materials, including charcoal, fireworks, fertilizers, chemicals, batteries and more, along with organics, in a given load of material. Emerson says that because many waste generators today are putting waste in plastic bags, often sealed, the mix of material in those bags creates what are essentially millions of mini compost ovens. “These bags sit there getting hotter and hotter,” says Emerson. “They get put into compactors, dumpsters and trucks, squeezing them closer and closer together, and there is an aerobic compost process in motion. The current system is bringing a lot of heat
sources close together, resulting in an ever-increasing heat feedback cycle. The temperatures have nowhere to go but up.” He adds that in summer, there is also generally more material in the waste stream from summer home improvement projects, including oil change rags, discarded paints, chemicals, aerosols, etc. When this mix of material is dumped on the tipping floor it is loosened up, says Emerson, just enough to allow the inflow of more oxygen, and increasing the possibility of material being hit with a spark from a loader bucket hitting the concrete, for example. “This is just what material needs at the moment it needs it, to convert into a deep-seated fire,” says Emerson.
The Lithium-Ion Battery factor
The increase in lithium-ion batteries in our waste stream has created the perfect storm for fire incidents. These batteries are becoming less expensive and more powerful, and are steadily increasing in number. This creates more potential fire hazard issues for the waste and recycling industry. According to Cameron Perks, a consultant for Industrial Minerals, “forecast demand for lithium-ion batteries is expected to increase up to seven-fold by 2024.” So, why do lithium-ion batteries have such potential to cause fires? According to Paul Shearing, a chemical engineer at the University College London, “Batteries can blow up or melt when internal electrical components short-circuit, when mechanical problems crop up after a fall or an accident, or when they are installed incorrectly.” Imagine the existing waste and recycling life cycle from trash to final separation. There are an infinite number of danger points where damage can occur to a tiny lithium-ion battery, increasing the risk of a mini explosion. So why don’t we just recycle all lithium-ion batteries? In practicality, they are so small that they can sneak into many places where they do not belong, and chances are high that the batteries are going to be damaged when being exposed to the “rough and tumble” environment of waste and recycling facilities. When these mini-explosions

equipment focus on fire focus: safety Handheld scrap analyzers poorly run operations. Some of the best operators in the industry are still victims of fire incidents. Why? The answer lies in the fact that most organizations focus the bulk of their operational and safety resources around the “Prevent” and “Mitigate” stages. They create processes and training programs that teach their employees how to use equipment and run their operations safely. Also, they train how to effectively deal with an emergency by finely balancing containment and response with employee and environmental protection. But how effective is the actual fire prevention and suppression system itself?

Layers of protection
So what happens when a fire incident occurs at a recycling operation? If it is caught and contained, everyone can breathe a collective sigh of relief. Alternatively, what happens if a fire occurs at a recycling operation and the fire gets out of control, causing significant damage? As an industry, for us to begin to solve the problem we are facing, we are wellserved to borrow an approach used by the chemical industry that looks at layers of protection to ensure the highest level of safety. From an article by Joy LePree published in Chemical Engineering Online, figure 1 (above) shows these layers of protection. The lowest two layers show the areas of prevention provided by the control system and operator intervention. The next two layers demonstrate where technology kicks in to prevent significant disaster from occurring. A typical “Active” protection layer consists of water sprinklers that are automatically set off when radiant heat passes 165 degrees. More often than not – they contain the fire. However, operations are temporarily offline. The cleanup process is sprung into action to restart the revenue-generating

operations of the business with the goal of having the shortest amount of downtime. Subsequent investigation begins as the management team starts to search for answers to what went wrong. Sometimes backroom discussions and finger-pointing might begin, typically concluding that a combination of the Operations and EH&S Departments at the organization need to develop better processes and training to avoid future incidents like the one that has occurred. The fact is that fire incidents that continue to plague the waste and recycling industry do not discriminate against
The fire rover system
Every fire incident has different costs, but outside of the obvious direct costs due to damaged equipment, building and materials, there are the indirect costs of downtime, insurance increases, fines, penalties, public exposure and more. Recently, a colleague of mine mentioned that in the case of a fire they experienced, their insurance premium increased from $150k per year to over $1M per year. They were also told that if they have another incident in the subsequent 24 months, their facility would be uninsurable. When it comes to using technology, most organizations use options that come standard with equipment, such as automatic sensors and shutoffs, along

with fire alarms, strobe lights and water sprinklers. For fire in industrial applications, this technology simply does not cut it. Developing standard operation and safety processes and procedures, while important, can only take a facility so far in lessening the risk of fires. An effective fire technology solution, such as the Fire Rover system, works diligently to provide a safety system that has the primary function of preventing incidents that may cause unplanned business interruption, property damages, pollution and/or injuries. A proper solution should be designed to detect an out-of-control process and take automatic action to ensure that the process and the plant are returned to a safe state. The solution should encompass a combination of proactive automated detection of excessive heat and its location; manual verification of the source of the abnormality; and on-site remotely operated coolant options to eliminate and contain the threat. The Fire Rover solution does all of this. It rapidly identifies fire in its incipient phase, alerts all forms of emergency response and initiates containment with coolant/pre-wetting options before the growth stage is realized. This leads to multiple benefits including improved employee and fire-fighting personnel safety, and because fire is detected in its earliest stage and is pre-wetted and cooled, it allows time to set up hoses, nozzles and connections to a water supply. Plus, heat buildup beneath structural elements is reduced along with smoke development. Additionally, the technology allows a fire service to locate the seat of the fire swiftly and surely. By using this kind of advanced fire detection and suppression system, fire footprint is exponentially reduced, preventing unplanned downtime, costly damage and safety hazards. The Fire Rover solution is a final layer of protection meant to compliment and function as part of the diligence and hard work that safety and operations teams have developed, maintained and worked to continuously improve upon. With Fire Rover technology, we have shifted the focus from containment of a major fire incident once underway, to early detection and cooling of a fire inci-
dent. This solution seamlessly integrates military-grade thermal detection (not IR, flame or smoke detection) with remote human verification and on-site remote targeted application of its cooling/wetting agent. The Fire Rover solution is currently installed in 100 waste and recycling facilities across the U.S. This solution
has extinguished over 78 fires in the past 12 months at the sites we protect. We are protecting assets including tipping floors, in-feeds, equipment, rubber feedstock, scrap metal, hazardous materials and more. The Fire Rover system typically Continued on page 60.

focus on Fire safety
managing gas, propane and other container hazards
Recently at a metal recycling facility a compressed gas cylinder exploded when it was cut with a metal shear. At a different facility, an explosion occurred when a vehicle ran over a plastic garbage bag. Workers didn’t know the bag contained a discarded propane tank. At another recycling facility, a propane tank exploded when it was inadvertently loaded into a shredder with a pile of scrap metal. The following is taken from a 2018 bulletin issued by WorkSafe BC and is meant to help employers identify hazards and reduce the risk of fire and explosions at recycling facilities.
ecycling facilities sometimes handle explosive or flammable containers such as household aerosol bottles, paint cans and propane tanks. The risk of fire or explosion is higher if these types of containers are crushed, compacted or shredded during the recycling process. Since workers are unlikely to know if containers hold any residual propellant or flammable or explosive substances, all such containers should be considered potentially hazardous.
What increases the risk of container fires and explosions?
Most incidents involve cutting, shearing, or compacting metal, especially when compressed gas containers are involved. For example, fires or explosions can occur when high-temperature tools, such as torches, are used to cut containers holding flammable substances. The contents can ignite and so can the paint on the containers. High-temperature tools can also produce sparks that may land on and ignite flammable materials nearby. Tanks and other containers may hold residual flammable or explosive substances when they are brought into recycling facilities. Workers may inadvertently miss a label indicating that a container may hold a flammable or explosive substance. In other cases, containers may be mislabelled or have no label, yet contain hazardous substances. The containers may be hidden inside garbage bags or in piles of other recycling, making them difficult to identify.
52 Recycling Product News July/August 2018
Tanks and other containers may hold flammable or explosive substances when they enter recycling facilities. Failure to remove these containers from the recycling process could result in fires or explosions when they are cut or compressed.
Reducing the risk
As an employer at a recycling facility, you can reduce the risk of fire due to container explosion by putting in place the following safe work practices: • Organize the worksite to isolate workers from potentially hazardous work processes, particularly metal shredding. • Develop and implement policies and controls to restrict or safely manage incoming pressurized containers. • Separate hazardous and flammable materials from all other materials as early as possible in the recycling process.
• Implement strict controls to prevent taking in items within bags or boxes. Employers should also provide sufficient time for workers to sort materials, train workers to recognize and respond to potential hazards, and ensure workers are provided with and use the necessary personal protective equipment (PPE) to protect them from workplace hazards. PPE should include conductive footwear and flame-resistant apparel when working with waste fuel. In addition, written procedures should be developed for workers to follow so they can safely deal with unknown substances whenever they are found. Other safe work practices that should be implemented to reduce the risk of fire due to container explosion include the following:
SAFETY TIPS: HANDLING COMPRESSED GAS CYLINDERS
• Improve safety in storage areas by eliminating ignition sources; taking steps to protect against possible collisions and spillage; and ensuring that a fire-suppression system is installed and firefighting equipment is available. •Ensure that containers used to sort and store incoming materials are suitable for flammable liquids. • Ensure that metal waste containers are bonded to grounded receiving containers to avoid buildup of static electricity. • Be aware of the potential for combustible dusts – including metal dusts – to accumulate. If combustible dust collects in a building or structure, or on machinery or equipment, it must be safely removed before built-up dust could cause a fire or explosion. • Segregate and monitor any contaminated soil and organic materials produced as by-products of recycling. Dispose of these materials as soon as possible in accordance with provincial requirements.
It is important to establish a written procedure for handling and storage of compressed gas cylinders. The procedure should include the following points: • Clearly mark cylinders “Full” or “Empty”; • Store cylinders upright, secured with a chain or strap, with valves closed and valve protective caps in place; • Keep cylinders away from combustible material, flames or ignition sources; • Avoid using greasy gloves when handling cylinders to prevent an explosion from the mixture of oxygen and petroleum-based lubricants; • Separate oxygen and fuel cylinders with a non-combustible barrier or store them 20 feet apart, and never near an exit; • Before processing any type of cylinder, make sure it is empty and that all pressure has been relieved; • Remove regulators before transporting cylinders; • Never transport cylinders with a magnet; • Hydraulic accumulators should only be dismantled by a hydraulic expert, and should NEVER be cut.

Solid waste industry fatality data for 2017 shows 18 percent increase In April, the Solid Waste Association of North America (SWANA) released its 2017 solid waste industry fatality data with 132 recorded fatalities – an 18 percent increase in total fatalities compared to 2016, with almost all incidents occurring in the U.S., rather than Canada. In 2017, the organization says there were 94 members of the public killed and 38 workers on the job, with over 75 percent of the incidents involving a private sector solid waste company. October 2017 had the most fatalities at 17, and no month in 2017 had fewer than eight. “I am disappointed in the waste industry’s safety performance in 2017 based on the fatality-related data that SWANA maintains,” said David Biderman, SWANA’s Executive Director and CEO. “There were an unacceptable number of preventable fatal incidents involving our trucks and equipment.”

The majority of deaths involving a member of the public occurred on the roadways, with 60 percent involving a solid waste vehicle and at least one other vehicle. Sixteen of these cases involved the other vehicle crossing into the lane of an oncoming waste vehicle. Ultimately, there were 94 thirdparty fatalities: 57 were drivers of or passengers in other vehicles, 23 were pedestrians, eight were bicyclists, four were motorcyclists and two occurred at disposal facilities. Of the 38 workers who died on the job in 2017, approximately 60 percent were killed during collection, 21 percent died at a landfill, with the remainder occurring at MRFs, transfer stations and other locations. In June, SWANA launched a new Hauler Safety Toolkit designed to bring together valuable resources into a usable, shareable format. The new toolkit is available from SWANA and is being handed out to solid waste haulers throughout North America at SWANA Hauler Safety Outreach events held regularly in Canada and the U.S.
Industry study points to broadband as top reversing safety solution
A recent study on industrial accident prevention has shown that broadband sound reversing alarms are nearly twice as effective than their tonal equivalents. The study, titled “Perceptions of Key Stakeholders Regarding the Utilization of Locatable Sound for the Prevention of Occupational Pedestrian Injuries and Fatalities” was conducted by Dr Rick Kilpatrick at the Indiana University of Pennsylvania, and is the first scientific study of broadband sound in the workplace. The quantitative research was undertaken in order to determine if the use of broadband sound reversing alarms improved workplace safety – compared to traditional tonal sound alarms – across a range of criteria, including audibility, propagation, frequency content and sound pressure maps. When respondents were presented with eight beneficial reversing alarm traits, broadband reversing alarms were selected by 61 percent of respondents as having more of these qualities, compared to the 33 percent of respondents who selected tonal reversing alarms. “Tonal alarms are common solutions to reversing compliance,” said Henry Morgan, CEO of Brigade Electronics Canada, a specialist in maneuvring safety solutions. “But they are non-directional, less safe and create significant noise pollution. Broadband sound mitigates all of the nuisances and dangers associated with tonal alarms and, as Rick’s research shows, is even more effective.”

lastword Reining in food waste Curbing the 40 percent loss of all food produced in canada to waste remains focus for compost Council – and should be the focus for all
by Susan Antler
We waste about 40 percent of all the food that is produced in Canada annually. . . with at least 75 percent of organic residuals still buried in landfills.” Susan Antler
ometimes when in the grocery store lineup waiting to check out, I look at my fellow shoppers, their filled carts, and wonder about our collective presumption that there will always be enough food to buy. Not whether we have the money to buy it, but rather will there be enough food, along with the variety and freshness, that we in the first world have come to expect? By now, we have all heard the estimates that collectively we waste about 40 percent of all the food that is produced in Canada annually. Martin Gooch of Value Chain Management presented these findings during the Compost Council of Canada’s recent webinar series, as well as at a past national conference. Gooch detailed the fact that food is wasted throughout the supply chain, with individuals (all of us) being the most careless with food waste, which is currently valued at a loss of about $31 billion annually. Even if one would say that a great deal of the work at our council and through our members benefits from the fact that there is food waste, the reality is that we are firmly on the side of not wanting food wasted in the first place. It’s a waste of tons of good finite resources
of all kinds, including time and effort, water, soil, air and energy. Thankfully there is some infrastructure across our country that can be used to effectively recycle organic resources, transforming them into products that can benefit both soil conditions and vitality. This infrastructure reality though is still not sufficient, with at least 75 percent of organic residuals continuing to end up being buried, and left to decay, in landfills, creating more greenhouse gas emissions – even with landfill gas capture technolo-
gies in place. To date, municipalities and private business have taken on most of the risk and financial responsibility to establish our existing organics recycling infrastructure. A system where brand owners contribute financially currently does not include organic residuals. In many cases, businesses can landfill their organics cheaper than sending them for recycling.

In addition, some existing funding programs have been

Turning this plan into a sustainable reality where food waste is minimized and the wise use of organic residuals are maximized should be a fundamental responsibility for us all.
We must work to give this vision and action plan every chance to succeed, otherwise we are all wasting our time and not owning up to our responsibility when it comes
to managing the food we produce and consume. Susan Antler is the executive director of the Compost Council of Canada.
