Abstract:

Waste Cooking Oil (WCO) is one of the most available renewable energy sources to produce Solid Alcohol Bio-Fuel (SABF) and biodiesel. The objective of this work is to carry the energy and cost analyses of biodiesel and SABF generation from Supernatant Waste Cooking Oil (S-WCO) and Bottom Waste Cooking Oil (B-WCO) from catering facilities in Iran, respectively. The total energy input/energy output for SABF and biodiesel, respectively, were 31.73/37.18 MJ/L and 34.269/42.161 MJ/L, with the most contribution of B-WCO/ S-WCO (78.78/73.573%), pursued by machinery (19.76/18.297%) and ethanol/methanol (0.684/7.467%). The energy ratio for SABF and biodiesel were 1.172 and 1.23, respectively. The renewable energy/nonrenewable energy inputs forms for SABF and biodiesel included 25.07/6.66 MJ/L (or 79/21%) and 25.28/ 8.986 MJ/L (or 73.78/26.22%) of total energy input, respectively. The total cost and revenue for SABF vs. biodiesel were 1.31 vs. 1.35 $/L and 5.62 vs. 2.481 $/L, respectively. The gross return, net return, benefit to cost ratio and productivity SABF vs. biodiesel generation were 4.324 vs. 1.458 $/L, 4.311 vs. 1.132 $/L, 4.294 vs. 1.839 (dimensionless) and 0.782 vs. 0.845 kg/$, respectively. Hence, concerning energy consumption for industrial production, urbanization and the existence of new energy consumption businesses such as the Bitcoin network, B-WCO and S-WCO can be used as a renewable feedstock for energy production such as SABF and biodiesel.
