In many agricultural regions across the world, farmers began to notice a disturbing trend: declining soil fertility, fewer earthworms, and falling crop yields. The culprit wasn’t always visible until they looked closely.
Over the years, plastic mulch films had become a standard practice for conserving moisture and reducing weeds. But post-harvest cleanup revealed a problem: fragments of plastic were left behind, season after season. These remnants accumulated in the soil, impacting microbial life and overall soil health.
That’s when a growing number of farmers made the switch to compostable mulch films.
The change was immediate and measurable. Cleanup became easier. Plastic pollution disappeared. Soil health began to restore itself, with visible improvements in earthworm activity, soil texture, and water retention. Yields improved, and farms moved closer to meeting organic certification requirements without the burden of plastic contamination.
This isn’t just about innovation, it’s about regeneration. Across the world, farmers are closing the loop between sustainability and productivity with compostable mulch films that protect both crops and the land they grow on.
Closing the Loop: From Planting to Regeneration
Across agricultural communities, many farmers are rethinking the tools they use. One tool under growing scrutiny? Conventional plastic mulch film. Once valued for moisture retention and weed control, it’s now known to leave behind harmful residues that damage soil and increase cleanup costs1.
Bio-Plastobag’s compostable mulch films are changing that narrative. These plant-based, certified compostable films perform like plastic during the crop cycle but break down naturally after use, improving soil health and reducing pollution2.
What Is Mulch Film and Why Do Farmers Use It?
Mulch films are thin sheets laid over soil to:
- Suppress weed growth
- Retain moisture
- Regulate soil temperature
- Improve crop yield and quality
- Reduce pesticide and herbicide usage
Traditionally made from petroleum-based polyethylene, plastic mulch films are functional but not sustainable. After harvest, they leave behind residues that pollute the soil and require labor-intensive removal.
The Plastic Problem in Agriculture
Most mulch films in use today are non-biodegradable. Here’s what that means:
- Residues persist and degrade into microplastics
- Cleanup is costly and often incomplete
- Microplastics disrupt microbial balance and soil health
- Contaminated mulch films cannot be recycled easily
These lingering fragments can remain in the ground for centuries, silently degrading farmland.
Microplastics: The Silent Soil Killer
Studies show that microplastics:
- Alter soil porosity and texture
- Interfere with microbial ecosystems
- Lower water and nutrient retention
- Enter the food chain through crops and water sources
And once embedded in the soil, they are almost impossible to remove.
A Smarter Solution: Compostable Mulch Films
Key Benefits:
- Biodegrade fully within a season
- No post-harvest removal needed
- Improve soil biodiversity
- Leave no microplastics or toxins
- Lower labor and disposal costs
This solution supports circular farming: enrich soil, reduce waste, and close the loop.
How Bio-Plastobag Mulch Films Work
During Cultivation: Laid with standard mulch-laying equipment
Post-Harvest: Tilled back into the soil
Decomposition: Triggered by soil microbes, heat, and moisture
End Result: Converts into CO₂, water, and organic matter that nourish the soil11

Environmental and Economic Benefits
By switching to compostable mulch films, you:
- Eliminate plastic waste at the source
- Save on post-harvest cleanup
- Improve soil health season after season
- Align with plastic ban regulations
Enhance eligibility for organic certification and sustainability grants
Farmer-Friendly Economics
Though compostable films may have a slightly higher upfront cost, they provide long-term ROI:
- No cleanup labor or landfill fees
- Better soil yields over time
- Reduced need for herbicides and pesticides
- Opportunities for green subsidies and certifications17
FREQUENTLY ASKED QUESTIONS
1. How long do Bio-Plastobag’s compostable mulch films take to decompose?
Under optimal field or industrial composting conditions, our mulch films decompose within 90 to 180 days. Factors like temperature, humidity, soil activity, and UV exposure influence the rate of breakdown.
2. Can compostable mulch films be left in the soil after harvest?
Yes. One of the key advantages of Bio-Plastobag’s mulch films is that they can be plowed into the soil after harvest, where they decompose without leaving microplastics or toxic residues behind.
