The present document examined the costs of the cottonseed oil to biodiesel transforming process and the returns from the byproducts using the microwave transesterification, a key technology in the development of biodiesel production. Capital expenditures and variable costs are part of biodiesel conversion costs. Initial investments in equipment are subject to capital investment, and variable costs including chemical, labour, fuel, electricity, and recurring cost of maintenance. The processing estimated has been measured for a daily output of 500 liters. In the report, clean cottonseed oil as feedstock was recommended. The operating time of the plant was also 8 hours, and transport, insurance and tax expenditure is 15 percent. The conversion cost of processing biodiesel with microwave assisted process was estimated to be around INR 3.35/ liter, so that INR 73.35/liter of pure biodiesel. This paper would indeed be useful for the purposes of research and development on biodiesel with microwave assistance.
