PRODUCTION OF BIODIESEL FROM WASTE MATERIALS

Abstract

The aim of this paper is to study the different processes of production of biodiesel from waste materials. Now a day the use of conventional fuels is increasing and these fuels are known for major cause of air pollution by the emission of carbon dioxide, particulate matter, sulfur dioxide and other harmful gasses.  On the other hand the sources of conventional fuels are very less and the price of conventional fuel is increasing day by day hence to minimize all these study resulting in alternative methods for the production of biodiesel.  The study conclude that the biodiesel  can be obtain from waste cooking oil and waste plastic by the process of transesterification  and  pyrolysis respectively. The process of transesterification is to convert the oils and fats into biodiesel with the help of different catalysts such as KOH and NaOH. The pyrolysis process is breaking of hydrocarbon chain of plastic into hydrocarbon chain of petroleum product by heating on high temperature of about 300°C in the absence of oxygen.
