Abstract:
The demand for the reduction of food waste in Oman has been increased during recent years. The rapid development of economic growth is throwing impact on the work-of-art of the solid waste. Food waste is generated from residential, industrial, commercial, and institutional sectors. Due to growing population and increasing consumption, the amount of solid waste is increasing. In arid region of Oman, solid waste generation was 19,100 ton/d in 2005. Generation of solid waste is expected to reach 30,000 tons/d in 2020. The high food waste content in MSW leads to its separation for use in anaerobic treatment in the available highest sources of VFA 2.89 g/l and SCOD 1980 mg/l. Biogas and methane yield were recorded to a maximum of 1.364 l/g-CODremoved.d (r=0.87), 0.912 L/g-CODremoved.d (r=0.99) and average methane content of biogas was 69%. The reactor was fully acclimatized at 55oC and achieved stability with high removal efficiency of COD, biogas production and emission reduction of CO2 of 89%. Thus, at 55oC temperature and OLR of 12.5 g-COD/L.d with 8 d HRT support a maximum biogas production of 1.37 L/g-CODremoved.d.
