Although fossil-based plastic products have caused severe environmental burdens, biotechnologies based on the mechanism of plastic biodegradation offer feasible approaches for the degradation, recycling, and valorization of plastic waste to alleviate environmental challenges. Recent advances in biotechnology-based biodegradation and the recycling and valorization of plastic waste provide feasible solutions for tackling the plastic waste dilemma.
Although fossil-based plastic products have many attractive characteristics, their production has led to severe environmental burdens that require immediate solutions. Despite these plastics being non-natural chemical compounds, they can be degraded and metabolized by some microorganisms, which suggests the potential application of biotechnologies based on the mechanism of plastic biodegradation. In this context, microbe-based strategies for the degradation, recycling, and valorization of plastic waste offer a feasible approach for alleviating environmental challenges created by the accumulation of plastic waste. This Minireview highlights recent advances in the biotechnology-based biodegradation of both traditional polymers and bio-based plastics, focusing on the mechanisms of biodegradation. From an application perspective, this Minireview also summarizes recent progress in the recycling and valorization of plastic waste, which are feasible solutions for tackling the plastic waste dilemma.
