What is biodegradable plastic mulch film and how does it benefit sustainable agriculture?
Biodegradable plastic mulch film is an environmentally friendly alternative to traditional polyethylene mulch films used in agriculture. Made from natural polymers like starch, polylactic acid (PLA), or other compostable materials, these films serve the same purpose as conventional plastic mulch — suppressing weeds, conserving soil moisture, regulating temperature, and improving crop yield — but with the added advantage of breaking down naturally in the soil after use.
One of the key benefits of biodegradable mulch film is that it eliminates the need for post-harvest removal and disposal, which can be labor-intensive and costly with standard plastic films. Over time, the biodegradable film decomposes through microbial activity, converting into water, carbon dioxide, and organic matter, thereby enriching the soil rather than polluting it.
For farmers practicing sustainable agriculture, biodegradable mulch film aligns with eco-conscious goals, reduces plastic waste in fields, and helps meet government regulations concerning single-use plastics. It’s particularly useful in organic farming and in regions with strict environmental policies. Though typically more expensive upfront than traditional plastic mulch, the savings in labor and disposal costs — combined with the environmental benefits — make it a cost-effective long-term investment.
