Application AutomotiveNews Compostable horticultural pot SelfEco, LLC is a manufacturer of earth-friendly gardening and catering products in Minneapolis-Saint Paul, Minnesota, USA. Their mission is to develop and manufacture compostable products made from plant-based plastics that will not be placed in landfills after use. SelfEco approached Green Dot Bioplastics (Cottonwood Falls, Kansas, USA) to develop a horticultural pot to add to their current gardening line that could compost once planted. Their current line only offered horticultural pots with nutrients and they wished to have a similar one without nutrients for third and fourth generation growers. Danny Mishek, President of SelfEco emphasized that the company advocates the manufacturing of compostable products because organic and plant-based materials can be used to solve a variety of environmental issues, such as adding nutrients to farmlands. SelfEco’s desire to develop an Earth-friendly and compostable horticultural pot without nutrients led them to seek out a partnership with Green Dot Bioplastics. There were three unique challenges the team faced while developing the final material because the horticultural pots: • Needed to retain an aesthetically pleasing look while also composting within a standard timeframe • Contained pull tabs that needed to cleanly break away • Had to maintain the integrity of their shape while on shelves but be able to compost once planted Due to these unique challenges, Green Dot Bioplastics needed to develop a customized formulation that differed from SelfEco’s original one. In regard to the first challenge, Mishek said the current pot would fade and discolor before it broke down and retailers were apprehensive about its retail appeal. Additionally, the pull tabs presented a unique challenge because the material needed a balance between its rigidity and ductility. Lastly, the material had to retain the shape of the horticultural pots while on store shelves and during handling but still break down once planted. The Green Dot Bioplastics team closely worked with the SelfEco team to develop an appropriate material that could address all these challenges while aligning with SelfEco’s mission. Green Dot Bioplastics was ultimately able to meet the aforementioned challenges and developed a final material that managed to exhibit the required characteristics. MT | Mass balanced EPS food packaging BASF’s customer Schaumaplast GmbH & Co.KG, an internationally active manufacturer of molded parts made from particle foams, is now offering packaging made from biomass-balanced Styropor ® . The Styropor MB used is the first EPS (expandable polystyrene) on the market to be produced using BASF’s biomass balance approach. Following special calculatory allocation philosophy, the TÜV SÜD-certified method can be used to replace the fossil resources needed to manufacture Styropor entirely with renewable resources right at the start of the production process. In a similar way to feeding green electricity into the power grid, the biomass balance concept incorporates renewable resources in the existing production processes. Each biomass balance product thus helps to conserve fossil resources and reduce greenhouse gas emissions. The formulation and quality of Styropor MB is unchanged compared to its fossil counterpart. “We are proud to be the first packaging manufacturer to launch a product made from biomass-balanced Styropor on the market. It is an innovation that scores points for its environmental impact without losing the foam’s tried-and-tested technical properties,” explains Bernhard Hauck, managing director at Schaumaplast in Reilingen, Germany. Schaumaplast is thus able to meet the high sustainability requirements of its customer: The young start-up company GmbH & Co. KG sends ice cream right across Germany fresh and with excellent thermal insulation in Styropor packaging. “Our quality ice cream is now delivered in high-quality packaging that is not only very good at keeping the product cool, but also helps the environment and climate by using renewable raw materials,” adds Ralf Schulze, co-founder and managing director of in Beeskow, Germany.

Application Automotive News Front grill of Mazda CX-5 Mitsubishi Chemical Corporation (MCC: Head office in Chiyoda-ku, Tokyo) has developed jointly with Mazda Motor Corporation (Hiroshima, Japan) a new grade of biobased engineering plastic DURABIO that can be applied to large automotive exterior components. The new grade has been adopted for the front grill of the Mazda CX-5. The biobased engineering plastic Durabio is made from isosorbide deriving from renewable plants. The material features superior properties compared to general biobased engineering plastics in terms of impact resistance, heat resistance and weathering, among other aspects. It also has good color-capability and, simply by adding pigments, creates a mirror-like smooth surface and deep color tone surpassing painted products with similar properties. Furthermore, its hard surface and resistance to scratch eliminates the need for any coating process, enabling reduction in volatile organic compound (VOC) emissions during manufacture. Capitalizing on these features, Durabio has being adopted for pillars and other exterior design components in addition to interior components, thus enhancing a broad range of applications in the automotive sector. The new grade of Durabio exhibits a good, balanced combination of superior resistance to impact and weathering and better formability due to improvement in resin composition compared with properties of conventional grades, thereby making it possible to apply the new product to the front grill and other large exterior components. The new grade is expected to be adopted for future models launched by Mazda following the CX-5. MCC will continue to accelerate R&D on Durabio to expand applications not just for automotive interior components but also for larger exterior design components, thus contributing to the production of environment-friendly motor vehicles. MT Biobased label With the EcoSource label, CCL Label is introducing a labelling solution that consists of components with up to 94% biobased share. Instead of using fossil raw materials its components are made from renewable resources. The processability and clarity of the chosen bioplastics and bio-based adhesives are claimed to guarantee secure performance and premium appearance. The label is suitable for PET and glass bottles alike (Source: PETplanet insider 10/17) MT bioplastics MAGAZINE [01/18] Vol. 13 29
