Application News Bioplastic housing for grain mill Until recently, the housings of the high-quality corundumceramic stone grinders of Wolfgang Mock (Darmstadt, Germany) were made of wood. Mock grinders make up about 70 % of all household mills sold and place the company prominently among European market leaders. The newest Mockmills come dressed in a Tecnaro housing, as announced in a recent press release dressed up in flowery words. Two models are encased in a stylish housing made of Tecnaro’s ARBOBLEND ® . Wolfgang Mock points out: “We have never used housing made of petroleum-based plastics for our mills.” It would not have suited the company philosophy. Now, the use of Tecnaro’s moulded wood also makes it easier to produce larger quantities of mills. The injection molding process allows for more streamlined, hence economical and faster production. This is how the Darmstadt-based family-run company is approaching the market, and the high-quality mills have received a warm welcome in markets across Europe and in the USA. The new Wolfgang Mock GmbH has the ambition to far exceed the 15,000 mills sold in one of the best years by his earlier company KoMo GmbH. And Wolfgang Mock is confident when he considers his decision to base his latest mills on the cooperation with Tecnaro. MT | Horticultural pots Using biopolymers for horticultural applications is something that makes eminent sense. At least, Growfun thinks so. Netherlands-based Growfun produces biodegradable horticultural pots from starchbased bio-based resin produced by Rodenburg Biopolymers in Oosterhout. Offering a sustainable alternative for fossil fuels, the company uses starch obtained from waste from the potato industry. According to Jan Blankestijn, managing director of Grofun, the company chose to collaborate with Rodenburg Biopolymers because of their expertise in that specific development area. “Based on their know-how, and in close collaboration with them we can develop a specific and high-quality product,” he said. Growfun is a flexible and innovative company that cooperates with customers and partners working with high-quality plastic products. The company invests considerable time and money in R & D, and, together with the University of Wageningen explores new technologies that they can apply to themes such as the circular economy. “Innovation plays a major role in both technology and design at Growfun, but only by investing continuously therein can we serve our customers quickly, expertly and professionally.” Growfun’s customers are national and international growers, exporters and retailers who demand a flexible, responsive supplier, for whom quality is an absolute given. MT Soybean oil enhances tire performance The Goodyear Tire & Rubber Company (Acron, Ohio, USA) is harvesting some unique seeds of innovation as it introduces a new tire technology with support from the United Soybean Board (USB). The first commercial use of a new soybean oil-based rubber compound is helping Goodyear enhance tire performance in dry, wet and winter conditions. A Goodyear team of scientists and engineers created a tread compound, or formulation, using soybean oil, which is naturally derived, cost-effective, carbon-neutral and renewable. “Goodyear’s legacy of innovation drives us to continue to apply new technology solutions, developing superior performing tires that meet consumer demands,” said Eric Mizner, Goodyear’s director of global materials science. By employing soybean oil in tires, Goodyear found a new way to help keep the rubber compound pliable in changing temperatures, a key performance achievement in maintaining and enhancing the vehicle’s grip on the road surface. Goodyear’s tests have shown rubber made with soybean oil mixes more easily in the silicareinforced compounds used in manufacturing certain tires. This also improves manufacturing efficiency and reduces energy consumption. Goodyear cooperated on the project with the USB, a group of farmer-directors who oversee the investments of a checkoff program on behalf of all U.S. soybean farmers. The USB provided some funding support for the development of Goodyear’s soybean oil application in tires. The commercialization of soybean oil in tires as the latest technology breakthrough by Goodyear builds on the company’s other recent innovations, such as the use of silica derived from rice husk ash.

Application News Compostable meat tray for organic meat In collaboration with Promessa (Deventer, The Netherlands) several members of the supermarket chain SuperUnie (including Coop and Poiesz) as well as EkoPlaza will switch to completely compostable and renewable meat trays by Bio4Pack to package organic meat. The tray, transparent film, label and absorption pad will all be biobased and compostable according to EN 134342, as well as indistinguishable from traditional meat packaging. “This is the first meat tray in the entire world which is completely compostable in accordance with the strict EN-13432 norm,” says Patrick Gerritsen from Bio4Pack. “Therefore, the tray may be labelled with the Seedling logo and can be thrown in the bin for organic waste after use. The tray and film are made of PLA, which is made from sugar cane. The impact of these trays on the environment is considerably less than traditional trays, as the resources are renewable. This means that no fossil resources are used at all. The absorption pad is made of cellulose and the Bio4Life label, including glue and ink, is completely compostable as well.” Bio4Pack started development of this organic tray back in 2006, and managed to keep its costs only a fraction higher than those of a traditional plastic tray. “It was quite a challenge. PLA is more fragile than other types of plastic, which means you have to add approved impact additives to the mix. In addition, the material must have good barrier properties and the packaging should be able to be mechanically processed with ease. However, the green colour was the biggest hurdle,” according to Patrick Gerritsen. An added benefit for retailers is that they will have to pay virtually no packaging tax for them. MT Organic soil conditioner bags The Montgomery County Department of Environmental Protection (DEP) has taken another step to protect the environment in Montgomery County (Maryland, USA) . DEP will partner with Braskem’s I’m Green polyethylene (PE) and ProAmpac’s Trinity Packaging Division to provide packaging for Leafgro ® , which is the County’s composted soil enrichment product. The new wrapping is a sustainable resource made from sugarcane. “I have made the commitment to improving the County’s environment a priority for my administration,” said County Executive Ike Leggett. “Adopting this more environmentallyresponsible packaging product reflects this commitment, as well demonstrating the County’s embrace of the Governor’s Sustainable Materials Management Policy, which seeks ‘an updated and more holistic materials management approach… to ensure continuous environmental improvement. I commend the Department of Environmental Protection and the Division of Solid Waste Services for their leadership in achieving this important accomplishment.”MT bioplastics MAGAZINE [06/17] Vol. 12 41
