Achieving Waste & Emissions Reduction Goals on University of Richmond Campus: The Biodigester Approach
This project proposes the installation of a small-scale anaerobic digester (biodigester). This is a reactor that breaks down biodegradable organic waste producing biogas. Food waste is considered one of the most efficient for producing biogas of typical biodigester feedstocks (Poschl, 2010). The UR Dining Hall produces 614 lbs of food waste per day to be used as feedstock, with landscaping scraps available for additional feed. The University boiler plant is capable of using biogas for heat production, making the plant a suitable destination for the digester's waste output. The digester may allow for waste diversion and greenhouse gas (GHG) emissions reductions while also saving money on transportation and natural gas.
