Structurally engineered cellulose-based mulch film with enhanced hydrophobicity and strength for green agriculture
This paper develops a cellulose-based mulch film coated with starch and a silane compound to mimic the strength and water resistance of conventional plastic agricultural film, achieving a water contact angle of 128 degrees (up from 16 degrees for untreated cellulose) and complete biodegradation in soil within 56 days. Unlike polyethylene mulch films that fragment into persistent microplastics in farmland, this material decomposes within a crop growing cycle, offering a practical biodegradable alternative for agriculture.
Are biodegradable mulch films a sustainable solution to microplastic mulch film pollution? A biogeochemical perspective
This review asks whether biodegradable mulch films are truly a sustainable alternative to conventional plastic films used in agriculture. Researchers found that biodegradable microplastics may actually accumulate more readily in soil than traditional microplastics because they require specific conditions to fully break down. The study warns that biodegradable films could alter soil carbon and nitrogen cycling, microbial communities, and greenhouse gas emissions in ways not yet fully understood.

Biodegradable Film Mulching Increases Soil Carbon Sequestration and Microbial Network Complexity in a Long-Term Field Study
Scientists studied biodegradable plastic mulch (the plastic sheeting farmers use to cover soil) and found it helps soil store more carbon and support healthier microbial communities compared to regular plastic mulch. However, the biodegradable plastic still breaks down into microplastics in the soil, raising questions about long-term environmental effects. This matters because while biodegradable farm plastics may help fight climate change by storing carbon, we still need to understand how the microplastics they leave behind might affect our food system.
Biodegradable Plastic Mulch Films: Impacts on Soil Microbial Communities and Ecosystem Functions
