可生物降解和可堆肥的塑料，特别是那些基于农业可再生资源的塑料，是一项重要的创新。这种创新为未来的技术提供了巨大的推动力。欧盟委员会第十二总司提出了欧洲生物降解塑料的大量就业机会和> 100万吨/年的潜在市场。基于淀粉的生物塑料利用了天然聚合以及原材料和工艺技术的可用性。热塑性淀粉TPS（R）和TPS（R）与疏水性生物可降解聚合物的共混物正在BIOTEC（R）的研究和生产计划中。最新的开发成果是反应复合工艺技术，以连续挤出工艺生产TPS（R）衍生物和淀粉酯。TPS（R）生物塑料颗粒BIOPLAST的应用是薄膜挤出和注塑成型。BIOFLEX薄膜具有机械性能，如PE薄膜不透明到透明，可印刷，可密封，可收缩，可着色。BIOFLEX对蒸汽具有渗透性，对氧气具有良好的阻隔性。BIOFLEX可以与传统箔相同的方式使用，例如用于垃圾袋，购物袋，包装，食品包装网，尿布，农业或技术用途。根据DIN 54900标准，TPS（R）生物塑料完全可生物降解和堆肥。这种生物塑料技术的创新是可持续发展的一个很好的例子，这意味着负责任地使用现有的自然资源和生产过程，考虑到环境方面和自然循环。(C)1998年爱思唯尔科学有限公司。All rights reserved.
Biodegradable and compostable plastics, especially those based on renewable resources from the agricultural industry, are an essential innovation. This innovation offers substantial impulses for the future technologies. A lot of jobs and a potential market of > 1 million tonnes/year for biodegradable plastics in Europe is proposed by the EU Commission Directorate General XII. Bioplastics based on starch use the benefits of natural polymerization and the availability of raw material and process technology. Thermoplastic starch TPS(R) and blends of TPS(R) with hydrophobic biodegradable polymers are in the BIOTEC(R) research and production program. Latest development results are reaction-compounding process technologies to produce TPS(R) derivatives and starchesters in a continuous extrusion process. Applications for TPS(R) bioplastic granules BIOPLAST are film extrusion and injection moulding. The BIOFLEX film has mechanical properties, such as PE films are opaque to transparent, printable, sealable, shrinkable and can be colourized. BIOFLEX is permeable to vapour and has good barrier properties to oxygen. BIOFLEX can be used in the same way as conventional foils, for instance for garbage sacks, shopping bags, packing up, nets for food packaging, diapers, agricultural or technical uses. According to DIN 54900, TPS(R) bioplastics are completely biodegradable and compostable. The innovation of this bioplastic technology is an excellent example for a sustainable development, which means the responsible use of available natural resources and production processes that take environmental aspects and natural circulations into consideration.
