Starch-based compounds are 100 percent biodegradable and compostable. Their properties and processing parameters can be compared to those of commodity plastics with the result that they can also serve as substitutes or extend their fields of application while offering an acceptable price level.
Starch compounds (Bioplast GS 902 and GS 902/P), manufactured by Biotech, can be processed without problems on classic injection molding equipment. The material has comparable properties to those of polypropylene, but its softening point is somewhat lower. The processing temperature is approximately 180 to 190C. The first uses are disposable shells, CD packaging, and grave-light covers.
