How It Works: From Waste to Wealth

Our anaerobic digesters use natural bacterial processes to break down organic matter in an oxygen-free environment, producing two valuable outputs.

1

Add Organic Waste

Feed kitchen scraps, animal manure, crop residues, and yard waste into the digester inlet—no sorting required.

2

Bacteria Break It Down

Microorganisms digest the material in a heated, oxygen-free tank over 15-30 days, producing methane-rich biogas.

3

Capture Clean Energy

Biogas flows to your generator, boiler, or stove—providing renewable energy for your home or farm operations.

4

Harvest Premium BioFertilizer

The biofertilizer is a pathogen-free, soil ammendment that provides soil pH, disease resistance, and plant growth benefits.

Environmental Impact

Make a Real Difference for Our Planet

Every Solar Flow digester prevents tons of methane emissions from entering the atmosphere while creating renewable energy and closing nutrient loops.

Reduce CO2 Emissions

Prevent 1,000 pounds of CO2 equivalent annually—equal to planting 25 trees each year.

Protect Waterways

Prevent nutrient runoff and groundwater contamination from improperly stored manure.

Close the Loop

Keep nutrients on your property instead of sending them to landfills—true circular economy.

"We're not just selling equipment—we're building a community of environmental stewards who prove that sustainability and profitability can go hand in hand."
