Abstract: Use of petro diesel as a fuel in diesel engine not only generates power but also gives out harmful gases which have negative effect on breathing air quality. Most of the countries of the world do not have crude oil reservoirs and hence importing crude oil from foreign countries to meet their energy requirements. To reduce the dependence on import of crude oil, many alternative fuels have found out. Biodiesel is considered as a best alternative fuel for conventional diesel oil because it is renewable in nature. Edible, inedible vegetable oil, animal waste fat and restaurant waste cooking oil are used for the production of biodiesel. Presently, biodiesel is not considered as economically viable option because it is costlier than conventional diesel oil. However, the price of biodiesel can be reduced by using low cost sources such as animal waste fat and restaurant waste cooking oil. İn this paper, an attempt has made to review the research that has already been carried out in methods for biodiesel production from animal waste fat. This paper also reviews the biodiesel specifications provided by different nations.

Keywords - Biodiesel, Animal waste fat, diesel oil, restaurant waste cooking oil.
