Summary

This review examines the environmental impact of agricultural plastic mulch film, which has led to significant microplastic accumulation in farm soils worldwide. Researchers evaluate various catalytic upcycling technologies including photocatalysis and thermocatalysis that can convert waste mulch into useful hydrocarbon resources with near-complete efficiency. The study also assesses the progress and remaining challenges of biodegradable mulch alternatives for sustainable agriculture.

Agricultural plastic mulch film, valued for its superior heat insulation and moisture retention, is widely used globally but has led to significant microplastic accumulation in soils, threatening agricultural ecosystems. This paper reviews its development and environmental impact, focusing on recycling and upcycling technologies, particularly catalytic recovery methods (with nearly 100% conversion efficiency) such as photocatalysis, thermocatalysis, and photothermal catalysis. It analyzes technical challenges and future directions in upcycling, emphasizing the role of catalysis in converting waste plastic mulch into hydrocarbon resources. This paper also evaluates the progress and challenges of biodegradable alternatives. By offering scientific insights and innovative approaches, it aims to reduce plastic mulch pollution, enhance resource utilization, and promote sustainable agriculture.
