Previous issue date: 2013-03-26 / The Life Cycle Assessment (LCA) of biodiesel pilot production from frying oil was performed. The scope includes from the collection stage of frying oil, extraction and processing of raw materials, to the production of biodiesel. The functional unit chosen was the production of 300kg of biodiesel. For comparative assessment of the current structure of the unit was developed alternative scenarios derived from the original version of the unit. The categories of impact selected for this evaluation were potential of climate change, ozone depletion, acidification and terrestrial depletion of fossil resources. Was visualized that variations of scenarios may result to impacts avoided and minimization of material use. Can be observed that the simple addition of alternative processes can collaborate with increase of emissions and variations of scenarios interchange internal values of Life Cycle Assessment and the final results may conceal what is happening during the process. Finally, this work brings ways to minimize the impacts of producing unit of biodiesel, basing choices on results and numerical expressions, in addition to environmental criteria. / Nesse trabalho foi realizado a Avalia??o do Ciclo de Vida (ACV) de Unidade Piloto de Produ??o de Biodiesel a parti de ?leo de fritura. O escopo integra desde a etapa de coleta de ?leo de fritura, extra??o e beneficiamento de insumos, at? a produ??o do biodiesel. A unidade funcional escolhida foi a produ??o de 300kg de biodiesel. Para avalia??o comparativa da atual estrutura da unidade foi elaborado cen?rios alternativos derivados da vers?o original da unidade. As categorias de impacto selecionadas para essa avalia??o foram Potenciais de Mudan?as Clim?ticas, Deple??o do Oz?nio, Acidifica??o Terrestre e Deple??o de Recursos F?sseis. Visualizou-se que as varia??es dos cen?rios podem acarretar em impactos evitados e minimiza??o de uso de materiais. P?de-se observar tamb?m que a simples adi??o de processos alternativos pode colaborar com aumento das emiss?es. Tamb?m se p?de notar que as varia??es de cen?rios alteram valores internos da Avalia??o do Ciclo de Vida e que os resultados finais podem esconder o que est? acontecendo durante o processo. Com isso esse trabalho traz formas de minimizar os impactos da unidade produtora de biodiesel, embasando as escolhas em resultados e express?es num?ricas, al?m de crit?rios ambientais.
