چکیده
Abstract To alleviate pollution and promote clean energy production, food waste can be used to produce methane through anaerobic digestion (AD). In this study, wheat straw was biochar (BC) magnetic (MB) as additives for AD of waste. MB2.5% BC2.5% led the highest production. The main action mechanism in change environmental factors upon stimulating microorganisms rapidly metabolize volatile fatty acids. stimulation microbial function increased abundance methanogenesis pathways. Methanosarcina most dominant archaea four modules, community changed more clearly with time than treatment. This study is innovative finding effectiveness BC MB treatments attributed especially treatment retained its advantage until later stage process.

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(...
متن کاملAnaerobic Digestion of Vegetable Waste
Fruit and vegetable wastes are produced in large quantities in Iran, and constitute a source of nuisance in municipal landfills. The objective of this study was to optimize the applications of anaerobic digestion for the treatment of municipal organic wastes. We studied the effect of organic loading rates on anaerobic digestion of vegetable wastes. The complete-mix, pilot-scale digester with wo...
