A solar‐biogas system was designed to dry food more efficiently than with solar energy alone. Processed papaya waste was anaerobically fermented to produce methane to augment solar energy for food drying. A gas with a minimum of 50% methane was produced at a rate of 0.38 liter methane per liter of digester volume per day with an organic loading rate of 1.60g of total volatile solids in the waste per liter of digester liquid volume per day in a once‐through system. Results indicate technical feasibility.
