There is currently significant interest in identifying solutions for dealing with plastic waste, and for the generation of new bio-derived plastics. The key aims of this project are to develop novel bio-catalytic methods to degrade plastics and use the fragments generated in synthetic applications. Also, to use new biological catalysts to convert chemical building blocks from sustainable biomass sources into polymer precursors. To achieve this, the PhD student will design and explore novel bio-catalysts for the degradation of plastics such as PET and screen reactions via colorimetric assays and analytical methods. Also, they will characterise the plastic degradation products formed and investigate biological chemistry, synthetic chemistry and synthetic biology methods to use the fragments formed. Furthermore, they will develop novel biological catalysts for use in reaction cascades to convert sugars from biomass into new polymer precursors to access new materials. This project falls within the catalysis, biological chemistry, synthetic biology and polymer materials EPSRC research themes.

目前，人们对寻找处理塑料废物和生产新型生物塑料的解决方案非常感兴趣。该项目的主要目标是开发新型生物催化方法来降解塑料并利用合成应用中产生的碎片。此外，使用新的生物催化剂将可持续生物质来源的化学构件转化为聚合物前体。为了实现这一目标，博士生将设计和探索用于降解 PET 等塑料的新型生物催化剂，并通过比色测定和分析方法筛选反应。此外，他们还将表征形成的塑料降解产物，并研究生物化学、合成化学和合成生物学方法以使用形成的碎片。此外，他们还将开发新型生物催化剂，用于级联反应，将生物质中的糖转化为新的聚合物前体，从而获得新材料。该项目属于催化、生物化学、合成生物学和高分子材料 EPSRC 研究主题。
