The numbers behind the mission.
Every roll of Coffee Kelp BioMulch is a direct intervention against plastic pollution, water scarcity, and organic waste. Here's what that means in measurable terms.
40% of US cropland is at desertification risk.
Soil moisture loss is the silent driver. We're building the solution.
Closing the loop on coffee waste.
The global coffee industry produces over 8 million tons of spent grounds per year. When landfilled, these grounds decompose anaerobically — releasing methane, a greenhouse gas 28× more potent than CO₂ over a 100-year horizon. Coffee Kelp BioMulch diverts this stream entirely, converting a liability into a functional agricultural input.
Every drop counts in a drying world.
Agriculture accounts for 70% of global freshwater withdrawals. Soil moisture loss from evaporation is one of the largest inefficiencies in dryland and irrigated farming alike. Our biocomposite film's hygroscopic kelp-alginate matrix creates a moisture-buffering layer at the soil surface, reducing irrigation demand and extending the interval between watering events.
No microplastics. No landfill. No residue.
Conventional LDPE mulch film is rated for single-season use but persists in soil for 400+ years. Fragments accumulate in topsoil, enter the food chain, and contaminate compost streams. Coffee Kelp BioMulch degrades to CO₂, water, and biomass within 6–8 weeks of soil incorporation — leaving behind nitrogen, potassium, and phosphorus as a soil amendment.
Mulch that feeds the soil it covers.
As the film biodegrades, spent coffee grounds release nitrogen (2.1% by weight), potassium, and phosphorus — functioning as a slow-release fertilizer. Kelp-derived alginates improve soil aggregate stability and cation exchange capacity. Fields treated with Coffee Kelp BioMulch receive both the protective benefits of mulch and a measurable soil amendment in a single application.
Side by side
Coffee Kelp BioMulch vs. conventional LDPE film.
| Attribute | Coffee Kelp BioMulch | Conventional LDPE |
|---|---|---|
| End-of-life | Fully biodegrades in 6–8 weeks | Landfill or field fragmentation |
| Microplastics | Zero | Accumulates in topsoil for centuries |
| Soil amendment | N, K, P release on degradation | None |
| Moisture retention | 63% reduction in evaporation | ~55% reduction (no buffering) |
| Feedstock | 100% waste-stream inputs | Virgin fossil-derived polymer |
| Carbon footprint | Net negative (waste diversion) | Positive (fossil extraction + landfill) |
