Summary

This review examines how insects and their gut microbes can break down plastic waste, covering species like mealworms and waxworms that can digest polyethylene and polystyrene. The bacteria living in insect guts are responsible for much of this plastic-degrading activity. Insect-based biodegradation could offer a scalable biological solution to reducing plastic pollution.

Plastic waste has recently been identified as one of the most serious environmental issues, affecting all life forms, natural habitats, and the economy, and is one of the most serious global environmental problems, second only to climate change. Seeking alternative environmentally sustainable options, such as biodegradation instead of conventional disposal, is critical in the face of this challenge. However, there is currently a lack of information about the mechanisms and efficacy of plastic biodegradation. From this perspective, this study aims to illustrate the negative environmental impacts of the plastic waste. It also addresses the role of insects and gut microbiota in the degradation of plastics, emphasizing the important role they will play in the future.
