Bio-diesel-Production from Used Cooking Oil: Alternative Energy and Production Cost and Benefit for Community Enterprises.

Abstract

Biodiesel is an alternative energy that can be produced from used cooking oil in the communities in Thailand and it is economically important because it was used to instead of Bio-diesel, especially in agriculture and transportation sector. Therefore, aims of research were to analyze and explore the production cost and return on production of renewable bio-diesel from used oil that were suitable for small manufacturers  at community level. The population – based study was selecting the specific sample 13 of community enterprises which was capacity for 205 liter per day. Questionnaires were tool for this research that based on validity of 0.81. Data analysis is used by Payback Period, Net Present Value and Internal Rate of Return. The project of 3 years and 9.50 percent discount rate which were computed. The result found that the project was valid at paybackperiod of 1 year and 10 months21days, netpresent value of 70,720 Baht and 29.85 % of internal rate ofreturn whereas B/C ratio was 1.02,which also indicated that project was economically valid.
