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

Anaerobic digestion of autoclaved and untreated food waste.
Anaerobic digestion of autoclaved (160°C, 6.2 bar) and untreated source segregated food waste (FW) was compared over 473 days in semi-continuously fed mesophilic reactors with trace elements supplementation, at organic loading rates (OLRs) of 2, 3, 4 and 6 kg volatile solids(VS)/m(3)d. Methane yields at all OLR were 5-10% higher for untreated FW (maximum 0.483±0.013 m(3) CH4/kg VS at 3 kg VS/m(...

Modeling and Removal of Hydrogen Sulfide from Biogas Produced by Anaerobic Digestion
Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...
