可完全生物降解材料PHA及其产业化

聚羟基烷酸酯PHA是一种新型的可完全生物降解的热塑性塑料,具有生物相容性、生物可降解性、压电性以及良好的使用与加工性能,其基本性能与聚丙烯相似,可在传统塑料加工机械上进行拉丝、模压、热注塑加工成型,可代替绝大部分石油基塑料原料,广泛应用于农业、环保、生物化工、微电材料、能源、医药、医用材料等领域。近年来,PHA在美国、德国等国已得到初步产业化应用,但成本过高,尚未进入规模化生产。意可曼公司以世界领先的基因工程菌种构造法,采用生物发酵技术合成PHA,突破了PHA产业化高成本与产品性能单一的技术瓶颈,性能优异,且其降解速度可根据不同的应用需要,由其共聚物的组分来控制,降解后最终产物进入碳的生物循环,构成完整的绿色循环经济体系。

Full-biodegradable material PHA and its industrialization

Polyhydroxyalkanoates(PHA)is a new kind of full-biodegradable thermoplastic,with charaeteristics of bio-compatibility,biodegradable,piezoelectric,and good performance of utility and processing.PHA holds the basic properties similar to polypropylene,and can be processed in drawing,molding,thermal plastics processing,etc.by conventional machine.Its applications areas include agriculture,biochemical,micro-electronic,energy,Medicine,Medical,etc. In recent years,PHA had received initial industrial applications in some countries such as American and German.but PHA didn't come into large-scale industrialization because of the high cost.Now Ecomann has produced PHA via formation with world-leading industrial genetic engineer(IGE)technologies and the first production line with an output of 5,000 ton/year PHA has been successfully running.Ecomann's products have lower cost and excellent performance.Its degradable rate varies to meet different application needs by ways of the co-component control. Then its final product comes into carbon biological cycle and thus constitutes a complete green circular economy.
