Extreme Cold Climate Solar Aided Anerobic Digestion of Organic Waste for Pathogen Removal and Energy Production

View Case Study

Summary

The United States Government is testing the feasibility of anaerobic digestion for sanitation in remote Alaskan Communities where piped systems are not sustainable. Reseachers are exploring the development of a solar augmented anaerobic digester to turn fecal matter, along with cardboard and other waste products from the community, into energy in the form of biomethane gas. Four digesters are being constructed using different insulation and the results from this pilot are expected in 2026.
