【 摘 要 】

In India kitchen waste is the largest component of the waste stream by weight. A major constituent of kitchen waste is Waste Fried Oil (WFO). After repeatedly frying waste fried oil is not suitable for human consumption. Everyday several litres of WFO are drained and dumped untreated. To meet growing energy needs resulting from demand and diminishing supply, alternate energy source "Bio-fuel" are receiving more attention. In addition, the increasing global concern has caused to focus on oxygenated fuels because of the environmental pollution from diesel engines. High viscosity and poor volatility are the major limitations of WFO for direct utilization as a fuel in diesel engines. Direct synthesis via transesterification of WFO will yield biodiesel. The general aim of this paper is to evaluate the assumed sustainability of waste fried oil from kitchen for biodiesel production and use. Biodiesel was produced from WFO using transesterification process with KOH as catalyst. Various properties of the biodiesel thus developed are evaluated and compared in relation to that of mineral diesel. Cost of production of biodiesel (WFOME) from WFO is also presented. The transesterification process output included 85 % of methyl ester (biodiesel), 9 % of glycerine, and 6 % of recovered methanol. WFOME properties were as per the ASTM specifications. The cost of biodiesel produced from WFO has been 65 % of the cost of subsidized mineral diesel.
