The Future of Mulch Is Already in Your Coffee Grounds.
Coffee Kelp BioMulch transforms two of the world's most abundant waste streams — spent coffee grounds and sea kelp — into a 100% plastic-free, biodegradable soil cover that saves water, enriches soil, and never ends up in a landfill.
The Problem
The numbers demand action.
of spent coffee grounds sent to landfill annually — releasing methane and CO₂ into the atmosphere.
of US land area is at risk for desertification. Efficient soil cover is no longer optional.
of water lost per field area annually in California alone through soil evaporation.
Patent Pending
Twin-Screw Extrusion
The Innovation
A Film That Feeds the Soil While It Protects It.
Coffee Kelp BioMulch is manufactured via a patent-pending twin-screw hot extrusion process — producing a biodegradable film and mulch particles with mechanical strength and moisture resistance previously unachievable without plastics or rubber.
- 100% plastic-free and rubber-free — no microplastic contamination
- Patent-pending twin-screw extrusion process for superior mechanical properties
- Acts as a slow-release fertilizer — no removal needed between crops
- Deployable by spreading, spraying, or falling-film coating
How It Works
Waste In. Fertility Out.
Source the Waste Streams
Sea kelp (marine brown algae) harvested from coastal ecosystems. Spent coffee grounds diverted from landfills — over 2 million tons generated annually in the US and Canada alone.
Twin-Screw Extrusion
Biomass is processed via hot twin-screw extrusion — a patent-pending thermoforming method that creates a hybrid hydrophobic/hydrophilic mesh with exceptional strength and moisture resistance.
Biodegradable Film & Particles
The result: a film or mulch particles that cover soil, reduce evaporation, suppress weeds, and biodegrade into slow-release fertilizer — eliminating costly removal and landfill disposal.
The Ingredients
Two Waste Streams. One Breakthrough.
Marine Brown Algae
Sea Kelp
Widely available in coastal ecosystems worldwide, sea kelp provides the structural backbone of the BioMulch matrix. Its natural biocomposite fibrils deliver mechanical reinforcement without any synthetic additives.
Agricultural Waste Diverted
Spent Coffee Grounds
Over 2 million tons generated annually in the US and Canada. Starbucks alone generates ~90,000 tons per year in the US. Globally, 6–8 million tons are produced yearly — the vast majority sent to landfills where they release methane and CO₂.
Every field. Every crop. Zero plastic.
