Biopolymer Innovation Award: Winners from Belgium, Brazil, and Germany

Biopolymer Innovation Award: Winners from Belgium, Brazil, and Germany

Brazil and Germany Bioplastics are conquering new areas of application, from construction to automotive industry. They help to minimize dependencies on oil and gas as well as the carbon footprint. And they are also becoming interesting alternatives in terms of price.

The winners of this year's BIOPOLYMER Innovation Awards, nominated by the jury, provide impressive evidence of those trends. During the award ceremony at the “BIOPOLYMER – Processing & Molding” congress on June 14, the winners from Belgium, Brazil, and Germany will exclusively present their innovations. Participants from all over the world can take part free of charge.

The abundance of high-quality applications from Belgium, Brazil, Holland, Italy and Germany was an exciting and demanding task for the jury of the BIOPOLYMER Innovation Awards this year again. After a multi-stage selection process, the jury nominated the following three companies as candidates for the main prize endowed with 2,000 euros (listed below in reverse alphabetical order of the company names):

• SachsenLeinen GmbH from Markkleeberg, Germany, developed a process for manufacturing unidirectional (UD) tapes from flax and hemp fibres and biobased plastics like PLA or PA. UD tapes are incorporated into moulded parts (e.g. of microcars, sports devices) to enable highly stable and resource-saving structures combined with effective vibration damping. The fibres, which are oriented in one direction, make it possible to "dose" stiffness and strength precisely in such components with minimal weight. The natural fibre reinforced UD tapes from SachsenLeinen can not only replace the usual glass fibre reinforced UD tapes made of polypropylene or other conventional plastics, but also set new price standards for natural fibre composite semi-finished products. The flax and hemp fibres grow in the region, the tapes can be recycled, thus reused as short fibre reinforced plastic. And depending on the used polymer they are biodegradable at the end of their lifespan.

• Home Eos SA from Farciennes in Belgium has developed a new type of biobased, biodegradable plastic: "stopsound" absorbs vibrations excellently, is naturally fire-retardant and heat-insulating. Its production requires up to eight times less energy than similar conventional plastics. The sound absorbing foam, which remains permanently elastic without plasticizers, solvents and classified chemicals, can be easily bonded to other materials. The material is used in vehicle construction as well as, for example, in floors, facades or in industrial noise protection. With the extensively certified bioplastic, classic petrochemical materials such as bitumen, PVC or EPDM can be replaced on a large scale in the future.

• Earth Renewable Technology (ERT) from Curitiba, Brazil, convinced the jury with a masterpiece in compounding technology which opens up new application possibilities for the world's most widely used biopolymer, polylactide (PLA). With its "Short Fibre Reinforced (SFRP) in FC 10130 biopolymer composite", the US company, which has been active in Brazil for four years, integrated PLA fibres into a PLA matrix. The resulting mono-material is not only extremely easy to recycle, but also gives significantly improved usage properties to PLA. According to ERT data, the elongation increases up to fifty times. Impact strength is quintupled, and the heat deflection temperature doubled. The barrier effect against water vapor increases up to twentyfold, that against oxygen up to fourfold. The technology can be used in injection moulding, extrusion processes and thermoforming.

During the award ceremony at the “BIOPOLYMER – Processing & Moulding” congress on June 14, the hand-made trophies will be presented to the victor, to the second and third placed applicants. The three winners will present their innovations and also be available to answer questions from the audience. AT
