Biodegradable Mulch Gains Ground Across US Fields

Farms test new mulch films as manufacturers race to cut waste and steady supply chains

14 Nov 2025

American growers are reassessing the use of plastic mulch, giving early attention to soil-biodegradable films that promise lower waste without disrupting tight production cycles. Adoption remains limited, but interest has grown as farms seek alternatives to conventional polyethylene and face stricter disposal rules.

Initial field trials indicate that newer films can match the performance of standard mulch in certain soils and climates. Results vary widely, however, as biological activity, weather and farm practices influence how well the material works. Rising removal costs have pushed many growers to focus on operational fit rather than symbolism.

Producers of biodegradable film see an opening in the US market. Houston Poly has begun domestic production and plans to increase capacity, while BASF is refining polymers designed to break down more consistently under American conditions. Analysts say the coordination among suppliers, researchers and growers resembles earlier periods of rapid agricultural technology adoption.

External pressure has also sharpened interest. Supply chain disruptions exposed the sector’s reliance on imported polyethylene mulch, while retailers and consumers have asked tougher questions about environmental impact across food supply chains. Biodegradable films appeal to farms seeking to reduce plastic waste and limit dependence on overseas shipments.

Obstacles remain significant. Cold soils can slow decomposition, and residue may persist if conditions are not favourable. Organic certification rules differ across states and regions, creating uncertainty for farms that depend on that label. Prices remain higher than for conventional mulch, although some of the premium can be offset by lower removal and disposal costs. Large-scale deployment is still rare, and many growers want data from multiple regions before making long-term decisions.

A market outlook released this summer projected strong global growth and highlighted rising US interest. Momentum is building, but the shift is at an early stage.

If the trend continues, biodegradable mulch could influence how US farms manage plastic and strengthen domestic supply chains. For now, growers, manufacturers and policymakers are watching to see whether the technology can deliver consistent results.
