This project aims to design enzymes that can be embedded into polyethylene, and later activated by the elevated temperatures of a compost heap, to depolymerise the plastic to small molecules. There are no good options available for the controlled decomposition of polyethylene waste at present, and instead researchers have focussed on solutions that rely on modifications to the underlying chemistry of the backbone and or collection to a central facility. Our approach would result in an in-built decomposition that does not require collection and recycling in a central facility. Since it is based on a depolymerisation mechanism it does not result in the production of harmful, partially disintegrated microplastics.

该项目旨在设计可以嵌入聚乙烯中的酶，然后通过堆肥堆的高温激活，将塑料解聚成小分子。目前没有好的选择可用于控制聚乙烯废物的分解，相反，研究人员将重点放在依赖于对主干的基础化学进行修改和/或收集到中央设施的解决方案上。我们的方法将导致内置分解，不需要在中央设施中收集和回收。由于它基于解聚机制，因此不会产生有害的、部分分解的微塑料。
