Raw material for biodiesel production. Valorization of used edible oil

Abstract

Biofuel’s production is a topical domain for researchers due to the relevance that it is winning every day. This, because of the increase in the petroleum price and the environmental advantages. Biodiesel is a promising way to reduce the environmental degradation by increasing pollutants including greenhouse gas emissions (fossil CO2, nitrogen and sulfur oxides). Biodiesel price is directly related to the cost of the used raw materials (70-95 % of the total biodiesel cost). In this context, the purpose of this paper is to study the different renewable resources which can be used as raw material for biodiesel production to emphasize the possibility of the use of edible used oils. The special attention is paid to optimization of biodiesel production from used edible oil by trans esterification reaction.
