BIODEGRADABLE POLYMER-COATED CRF TECHNOLOGY*
Next-generation eco-friendly coating derived from bio-based polymers that fully degrades naturally in soil without leaving synthetic microplastic residues.
TECHNOLOGY OVERVIEW
Driven by global sustainability targets and strict microplastic regulations, Kingenta is pioneering the research and pilot-scale development of Biodegradable Polymer-Coated Controlled-Release Fertilizer (CRF) technology. Led by the National Engineering Technology Research Center for SCRF, this initiative targets 100% soil bio-degradability while maintaining precise nutrient release control.
REVOLUTIONIZING SUSTAINABLE COATING MATERIALS
Traditional polymer-coated fertilizers rely on synthetic elastomeric polymers that take decades to breakdown, contributing to microplastic accumulation in agricultural soils. Kingenta's dedicated R&D team is breaking material boundaries by converting renewable, bio-based raw materials into fully degradable coating membranes.
By overcoming historic challenges such as cellulose agglomeration and premature moisture burst, Kingenta's proprietary molecular microporous modification technology regulates film formation to deliver temperature-synchronized release alongside complete environmental safety.
3 CORE BIO-DEGRADABLE MATERIAL PATHWAYS
Proprietary material innovations currently undergoing advanced laboratory and pilot-scale verification.
Bio-Based Polyurethane Materials
Developed using proprietary renewable plant-oil and agricultural-residue chemistry. Composite reinforcement techniques eliminate film tearing while providing superhydrophobic moisture barriers.
Bio-Degradable Plant-Starch Polymers
Derived from fermented plant starches, these coating membranes provide rigid structural encapsulation during crop growth and naturally decompose into harmless water and carbon dioxide under soil microbial action.
Degradable Polyester Polymers
Formulated with a proprietary blend of biodegradable macromolecular polyesters. Film-forming mechanisms are optimized to match nitrogen release curves with field crop uptake requirements.
KEY ADVANTAGES & SUSTAINABILITY BENEFITS
Targeted environmental and agronomic performance expected upon full commercialization.
Zero Microplastic Soil Residue
100% soil bio-degradability eliminates long-term synthetic polymer accumulation in arable lands.
Renewable Carbon-Neutral Feedstocks
Utilizes agricultural by-products (plant oils, straw, and cellulose), reducing reliance on petroleum-based polymers.
Microporous Controlled Release
Molecular microporous modification prevents early burst release, preserving temperature-regulated diffusion.
EU Bio-Degradability Compliance
Engineered to satisfy future European Union and international environmental regulations regarding microplastic bans.
Non-Toxic Microbial Degradation
Membrane breakdown products produce natural organic intermediates that nourish soil microbial ecosystems.
Crop-Specific Longevity Matching
Configurable for 30 to 180+ days release profiles tailored for broad-acre cereals, vegetables, and fruit crops.
