     food and yard wastes are available year round at low cost and have the potential to complement each other for ss-ad. the goal of this study was to determine optimal feedstock/effluent (f/e) and food waste/yard waste mixing ratios for optimal biogas production. co-digestion of yard and food waste was carried out at f/e ratios of 1, 2, and 3. for each f/e ratio, food waste percentages of 0%, 10%, and 20%, based on dry volatile solids, were evaluated. results showed increased methane yields and volumetric productivities as the percentage of food waste was increased to 10% and 20% of the substrate at f/e ratios of 2 and 1, respectively. this study showed that co-digestion of food waste with yard waste at specific ratios can improve digester operating characteristics and end performance metrics over ss-ad of yard waste alone.
