Biodegradable Mulch Film Additive
report_problem Problem Statement
Polyethylene mulch film is used on millions of hectares globally for weed suppression and soil moisture retention but creates massive disposal problems. Existing biodegradable mulch films (PLA, PBAT blends) degrade too quickly or too slowly depending on climate, and often fragment into microplastics before fully mineralizing. An additive using naturally-derived compounds could tune degradation rate to match growing season length.

flag Success Criteria
Film maintains ≥80% tensile strength through 90-day growing season, achieves >90% disintegration by mass within 24 months in field soil per EN 17033, produces <10 fragments >1mm per gram of original film, and shows no ecotoxicity per OECD 208
precision_manufacturing Equipment Needed
Blown film extrusion line (lab or pilot scale), outdoor field plot access, universal testing machine, soil sampling equipment, stereomicroscope for fragment counting, ZnCl2 density separation setup for microplastic analysis, weather station for field site, PBAT resin
