法国Carbios公司于2015年12月3日宣布,开发了一种酶法过程,可允许基于商业产品的无定形聚对苯二甲酸乙二醇酯(PET)100%解聚成其原始的单体:精对苯二甲酸(PTA)和乙二醇。该工艺过程使用高选择性的酶,省去了分类步骤,并提供了100%循环利用率的前景。PET被广泛用于生产塑料瓶和其他包装,然而传统的实施PET废物回收的技术对其它聚合物和杂质污染非常敏感,并且导致产生较低质量的二次产品。此 Carbios, France, announced on December 3, 2015 that an enzymatic process was developed that would allow 100% depolymerization of amorphous polyethylene terephthalate (PET) based commercial products into their original monomers: fine Terephthalic acid (PTA) and ethylene glycol. The process uses highly selective enzymes, eliminating the need for sorting steps and providing a promise of 100% recycle. PET is widely used in the production of plastic bottles and other packaging, however the traditional techniques for implementing PET waste recycling are very sensitive to other polymer and impurity contamination and result in lower quality secondary products. this
