Microbial biotechnologies for plastic degradation, depolymerization, and valorisation represent a burgeoning field with significant potential for addressing the global plastic waste crisis. The use of microbial processes to enzymatically degrade plastics offers a promising solution to the persistent problem of plastic pollution. Current research has demonstrated that microbial catalysts can break down recalcitrant plastic polymers into manageable and recyclable degradation products. This approach not only provides an eco-friendly alternative to traditional plastic disposal methods but also aligns with the principles of a circular economy by potentially transforming waste into valuable resources. Despite these advancements, there remain substantial gaps in our understanding of the mechanistic details of microbial depolymerization and the scalability of these bioprocesses. Addressing these gaps is crucial for the development of sustainable and economically viable plastic waste management strategies.

This research topic aims to advance the field of microbial technologies for plastic degradation by fostering fundamental and applied research. The primary objectives include elucidating the mechanistic details of microbial depolymerization of recalcitrant plastics and evaluating the potential for scaling up well-understood bioprocesses. Specific questions to be addressed include: What are the key enzymes and microbial pathways involved in plastic degradation? How can these processes be optimized for industrial-scale applications? What are the techno-economic and environmental impacts of implementing these microbial technologies on a large scale? By answering these questions, the research aims to contribute to the development of innovative, sustainable, and economically viable solutions for plastic waste management.
