Recovery of biogas from food waste using treated and untreated anaerobic digestion

Abstract Biogas is an environmentally friendly, clean, and low-cost renewable energy source. This alternate sustainable source can be used for heat, power, or fuel making it a good alternative energy. produced through anaerobic digestion of biodegradable organic materials without oxygen improved by performing thermal treatment. In this study, biogas was recovered using treated untreated food waste. The characterisation waste its suitability process studied total solids, volatile pH value, C/N ratio, following the APHA standard. in water bath at temperature 70 °C 45 minutes. Biochemical Methane Potential method conducted to determine production from digestion. were anaerobically digested mesophilic 37 speed 100 rpm 15 days. measured daily displacement method. 198.70 mL, meanwhile 185.50 mL. Treated showed slightly higher days 13.2 yield obtained 51.21 mL/g 47.80 every 1 g wet sample. study found that treatment helps degradation content digestion, which leads recovery.
