Frequently Asked Questions

An anaerobic digester breaks down organic waste (like kitchen scraps, yard waste, and farm manure) in an oxygen-free environment. Bacteria naturally convert the waste into biogas (methane and carbon dioxide) and nutrient-rich liquid biofertilizer. The biogas can be used for heating or electricity, while the biofertilizer can be applied directly to lawns, gardens, or fields.

The Nova 275 model, our most popular unit for homes and small farms, is typically $4,000 including professional installation. This price is before any applicable Federal/State incentives.

Solar Flow digesters are designed for fully automated, hands-off operation. Most units require less than 1 hour of maintenance per month, which includes checking the system and occasionally adding beneficial bacteria. There's no daily feeding schedule—the system handles organic waste automatically.

Solar Flow digesters accept a wide variety of organic materials. Approved inputs include: kitchen scraps (vegetable peels, fruit scraps, coffee grounds, eggshells, bread, grains, and cooked rice/pasta), yard waste (grass clippings, leaves, plant trimmings), and farm waste (animal manure from herbivores like cows, horses, goats, and poultry).

The Nova 275 produces a maximum of 547 gallons of liquid biofertilizer per year. This is enough to fertilize up to 43,560 square feet of lawn, garden, or farmland per year. The biofertilizer is nutrient-rich and can be applied directly through irrigation systems or sprayed onto soil.

Most customers see a payback period of 4-5 years, depending on their current fertilizer, energy, and waste disposal costs. With Federal/State incentives and annual savings of $1,000+ on fertilizer, energy, and waste fees, the return on investment is substantial.

Yes, professional installation is included in the purchase price. Our team will assess your property, prepare the site, and install the digester properly. The unit requires outdoor space of approximately 4' x 13' and access to a standard electrical outlet.

Absolutely! Solar Flow digesters are specifically designed for Pacific Northwest conditions. The insulated units maintain optimal temperatures year-round, even during Washington winters, and the system continues producing biogas and biofertilizer in all seasons.
