Comparison of high-solids to liquid anaerobic co-digestion of food waste and green waste
(2014) In Bioresource Technology 154. p.215-221- Abstract
- Co-digestion of food waste and green waste was conducted with six feedstock mixing ratios to evaluate biogas production. Increasing the food waste percentage in the feedstock resulted in an increased methane yield, while shorter retention time was achieved by increasing the green waste percentage. Food waste/green waste ratio of 40:60 was determined as preferred ratio for optimal biogas production. About 90% of methane yield was obtained after 24.5 days of digestion, with total methane yield of 272.1 mL/g VS. Based the preferred ratio, effect of total solids (TS) content on co-digestion of food waste and green waste was evaluated over a TS range of 5–25%. Results showed that methane yields from high-solids anaerobic digestion (15–20% TS)... (More)

Results showed that methane yields from high-solids anaerobic digestion (15–20% TS) were higher than the output of liquid anaerobic digestion (5–10% TS), while methanogenesis was inhibited by further increasing the TS content to 25%. The inhibition may be caused by organic overloading and excess ammonia. (Less)
