Global agriculture relies heavily on polyethylene (PE) mulch films, with millions of tons applied annually to boost productivity. However, this reliance has come at a staggering environmental and financial cost. Conservative estimates indicate that residual rates of traditional film reach 5-10% annually, leading to long-term accumulation that triggers severe soil compaction, disrupts microbial ecosystems, and interferes with crop root development. This “White Pollution” does not just stay in the field—it fragments into microplastics that infiltrate the global food chain.
For modern growers and enterprises, the burden is two-fold:
- Economic Drain: Traditional films demand intensive manual labor for post-harvest collection and disposal, significantly inflating operational costs.
- Regulatory Pressure: With tightening global “plastic bans” and ambitious carbon neutrality targets, conventional plastics are becoming a liability rather than an asset.
Is there a solution that maintains high crop yields while eliminating the need for removal? Imagine a mulch film or seedling pot that, after its functional life, can be simply plowed into the soil to undergo complete, natural biodegradation—leaving behind only water, CO2, and nutrient-rich biomass. This is the promise of PHA (Polyhydroxyalkanoates): the ultimate bridge between agricultural profitability and ecological integrity.
What is PHA? Why It's the Ultimate Solution for Soil-Biodegradable Agriculture
PHA (Polyhydroxyalkanoates) is a class of high-performance biopolyesters synthesized by microorganisms through the fermentation of renewable resources like plant oils and sugars. As a 100% bio-based material, PHA is not just a plastic substitute—it is a biological nutrient.
What truly sets PHA apart is its “All-Environment Biodegradability.” Unlike PLA (which remains largely intact in soil without industrial composting temperatures), PHA is recognized as “food” by indigenous soil microbes. It undergoes complete metabolic conversion into CO₂, water, and biomass within weeks to months, depending on film thickness and local climate. It is currently the only material that guarantees true, residue-free degradation in both soil and marine environments.
Comparative Performance: Why PHA Leads the Market
To understand why PHA is the premium choice for sustainable agriculture, we must compare it with existing materials:
| Material Type | Degradation Conditions | Soil Degradation Speed | Agricultural Suitability | Primary Drawback |
| Traditional PE | Non-degradable | Decades to centuries | Low (Requires removal) | Severe “White Pollution” |
| PLA | Industrial Composting | Extremely slow in soil | Limited | Leaves residues in nature |
| PBAT | Specific microbial conditions | Moderate to Good | Common but variable | Mechanical limitations; potential residue |
| Our PHA | Natural Soil/Water | Weeks to Months | Excellent (Premium) | None; Fully integrates into soil |

Key Advantages of PHA in Agricultural Mulch Film Applications
Agronomic Performance & Yield Optimization
Our PHA resins enable the production of films that increase soil temperatures by 5-10°C and reduce irrigation needs by 20-30%. Meta-analyses confirm that crops under PHA mulch achieve yields and quality comparable to—and sometimes exceeding—traditional PE, ensuring early harvests and premium market entry.
"Zero-Labor" Economics
The “Zero-Burden” model eliminates the costly post-harvest recovery phase. By allowing direct plowing of residues, farmers save $10–$25 per acre in labor and disposal fees, while preventing plastic fragments from tangling in machinery or causing soil compaction.
The Science of Sustainability: Beyond Just Biodegradation
This is where PHA truly stands alone as the “Ultimate Solution”:
- Complete Elimination of “White Pollution”: Unlike oxo-fragmentable plastics, PHA undergoes 100% microbial mineralization. It doesn’t just break into pieces; it vanishes entirely.
- Active Carbon Sequestration: Derived from renewable biomass, PHA serves as a carbon source for beneficial soil microbes. It supports global “Carbon Neutrality” goals by returning atmospheric carbon back into the soil ecosystem.
- Total Bio-Safety: Our material is 100% bio-compatible and non-toxic to soil fauna, microbiota, and root systems, ensuring long-term land viability and supporting Green/Organic Certifications.
Proven Success Across High-Value Crops
Engineered for versatility, our resins provide a competitive edge in:
- Vegetables & Fruits: Strawberries, watermelons, peppers, and tomatoes.

PHA Biodegradable Seedling Pots: Seamless Transplant with Zero Pollution
Beyond mulch films, PHA resin technology is transforming the nursery sector through direct-plant seedling containers. Traditional plastic pots are a logistical and environmental burden: they generate massive plastic waste and often trigger transplant shock when root systems are disturbed during removal. PHA containers provide an elegant, “one-touch” solution: plant the pot, save the plant.
Seamless Growth & Near-100% Survival Rates
Engineered for “Root-Through” performance, our PHA resins allow for the entire pot to be planted directly into the soil.
- Total Root Integrity: Seedlings remain undisturbed, eliminating the risk of transplant shock and ensuring vigorous early-stage growth.
- Enhanced Survivability: By preserving the complex root structure, farmers see a dramatic increase in survival rates, especially for delicate or high-value varieties.
Natural Degradation & Soil Enrichment
Once buried, the PHA pot is naturally colonized by soil microbes. The pot walls are calibrated to remain sturdy during the nursery phase but become porous and fully biodegrade into water, CO₂, and organic biomass once in the ground. Instead of creating a waste-disposal crisis, the container becomes a soil amendment, promoting healthy microbial activity around the root zone.
ersatile Solutions for High-Value Agriculture
Our PHA resin grades are specifically formulated to meet the nursery requirements of diverse sectors:
- Food & Cash Crops: High-value vegetables, peppers, and strawberries.
- Industrial Forestry: Rapid reforestation and commercial timber nurseries.
- Perennial Crops: Coffee, fruit trees, and ornamental floriculture.
“The combination of PHA mulch film with PHA seedling pots creates a fully integrated, zero-waste growing system. From the nursery to the final harvest, the grower manages a biology-based process rather than a waste-management crisis.
