Automated anaerobic digesters for Washington lawns, gardens, and farms. Reduce or eliminate fertilizer, energy, and disposal fees.
Designed specifically for Pacific Northwest conditions, our automated systems turn your waste into a valuable asset.
Biofertilizer from anaerobic digestion naturally carries an average NPK profile of 3‑1‑5, but its value goes far beyond nutrients. Research shows that AD‑derived biofertilizers:
It's a biological input that feeds the crop and the soil ecosystem behind it.
Apply liquid biofertilizer directly through your irrigation system—no heavy lifting, no spreaders, and no extra field labor.
Turn kitchen scraps, yard waste, and farm manure into clean biogas for heating, cooking, and electricity generation.
Our anaerobic digesters use natural bacterial processes to break down organic matter in an oxygen-free environment, producing two valuable outputs.
Feed kitchen scraps, animal manure, crop residues, and yard waste into the digester inlet—no sorting required.
Microorganisms digest the material in a heated, oxygen-free tank over 15-30 days, producing methane-rich biogas.
Biogas flows to your generator, boiler, or stove—providing renewable energy for your home or farm operations.
The biofertilizer is a pathogen-free, soil ammendment that provides soil pH, disease resistance, and plant growth benefits.
Real savings from turning waste into valuable resources.

Potential value generated from your waste
After your system pays for itself, enjoy decades of free energy and biofertilizer production. Plus, take advantage of federal and state renewable energy incentives to reduce your upfront investment.
Our digesters are specifically designed for the unique needs of homesteads and small farms in the Pacific Northwest.
Transform your kitchen scraps into a premium lawn and garden soil amendment. Stop buying fertilizer and create the healthiest lawn on your block.
Process animal manure and crop waste into biogas for heating greenhouses or powering equipment, plus liquid biofertilizer for fields.
Create certified organic biofertilizer from crop residues and maintain sustainability certifications while reducing input costs.
We'll analyze your waste streams, nutrient, and energy needs at no cost
Every SolarFlow digester prevents methane emissions from entering the atmosphere while creating renewable energy and closing nutrient loops.
"SolarFlow was founded on the belief that small farms and homeowners deserve access to affordable, regenerative technologies that reduce waste, improve plant growth, and support long‑term environmental and economic resilience."
