Abstract	O panorama estabelecido atualmente sobre as fontes renovaveis de energia sinaliza que sua relevância tem assumido um crescente papel na matriz energetica mundial, uma vez que as reservas de combustiveis fosseis - devido a grande demanda energetica - vem sofrendo drasticas reducoes e sua ampla utilizacao gera a necessidade de maior cuidado com as questoes ambientais. Entre as alternativas renovaveis de energia, o biodiesel mostra-se como uma alternativa altamente promissora. Biodiesel e uma fonte de energia renovavel, ou seja, um combustivel liquido, proveniente da biomassa, para veiculos automotores, cujas fontes mais frequentes sao oleos vegetais, gorduras animais e gorduras residuais, que devem passar pelos processos de transesterificacao, formacao de microemulsoes ou pirolise. A utilizacao de oleos residuais como materia prima tem se tornado muito interessante, pois alem do grande potencial energetico, a reciclagem destes traria beneficios tanto na vertente socio-economica como tambem em funcao do baixo custo da referida materia prima. Palavras-Chave: Biodiesel, Oleo Residual, Transesterificacao. Abstract On the current panorama for renewable energy signals that its relevance has increased in the global energy matrix, since the reserves of fossil fuels - due to the large demand for energy - have suffered drastic reductions and their widespread use makes concern for environmental issues necessary. Among the alternative renewable energy sources, biodiesel appears as a highly promising alternative. Biodiesel is a renewable energy source, that is to say a liquid fuel derived from biomass for the purpose of transport, whose sources are most commonly vegetable oils, animal fats and waste fats, which must undergo the process of transesterification, formation of microemulsions or pyrolysis. The use of waste oil as a raw material has become very appealing, because besides its potential for generating energy, recycling these has socio-economic benefits and the cost of the raw material is low.
