| Abstract |
Plastics are commonly used in daily life and various industries, generating massive quantities of plastic wastes and causing severe environmental concerns. Thus, the upcycling of plastic wastes into valuable products has recently emerged as an option for addressing the plastic-induced environmental crisis. Since (i) the discovery of plastic-eating species and (ii) the discovery of an enzyme that hydrolyzes polyethylene terephthalate (PET), one of the most commonly used synthetic polymers that is remarkably persistent in the environment, the enzymatic and/or microbial degradation of plastic wastes and the catabolism of plastic monomers have been intensively studied. In this review, we focus on recent advances and key barriers in the biotechnological upcycling of plastic wastes. We also given an overview of the microbial degradation of plastic wastes. Specifically, recent research on the biodegradation of plastics via PET hydrolase (PETase) as a representative plastic-degrading enzyme is dis-cussed. Additionally, this review covers (i) the microbial conversion of plastic monomers from mainly PET and polyurethane (PU) and (ii) the chemobiological upcycling of plastic wastes. Ultimately, this review provides insight into the development of viable biotechnological plastic upcycling systems and contributes to the con-struction of plastic-based circular carbon economies. |
