Several concurrent developments are shaping the future of plastics. A transition to a sustainable plastics system requires not only a shift to fossil-free feedstock and energy to produce the carbon-neutral building blocks for polymers used in plastics, but also a rational design of the polymers with both desired material properties for functionality and features facilitating their recyclability. Biotechnology has an important role in producing polymer building blocks from renewable feedstocks, and also shows potential for recycling of polymers. Here, we present strategies for improving the performance and recyclability of the polymers, for enhancing degradability to monomers, and for improving chemical recyclability by designing polymers with different chemical functionalities.

设计用于塑料的生物基可回收聚合物。

几项并发的发展正在塑造塑料的未来。向可持续塑料体系的过渡不仅需要转变为不含化石的原料和能源，以生产用于塑料的聚合物的碳中和性砌块，而且还需要对聚合物进行合理的设计，同时兼顾功能和特性所需的材料特性。促进其可回收性。生物技术在利用可再生原料生产聚合物构件方面发挥着重要作用，并且还显示出聚合物回收的潜力。在这里，我们提出了通过设计具有不同化学官能度的聚合物来改善聚合物的性能和可回收性，增强对单体的降解性以及改善化学可回收性的策略。
