Solar Flow Digester liquid biofertilizer

Premium Liquid BioFertilizer

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:

  • Improve soil health
  • Enhance disease resistance
  • Stimulate plant growth

It's a biological input that feeds the crop and the soil ecosystem behind it.

Reduce fertilizer costs by 100%

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.
