A Biorrefinaria Experimental de Resíduos Sólidos Orgânicos (BERSO) do Departamento de Energia Nuclear da Universidade Federal de Pernambuco (UFPE) produz biodiesel a partir de rejeitos de óleos e gorduras de cozinha produzidos na própria Universidade. Esse tipo de produção do biodiesel aparece como uma alternativa para a produção do biocombustível a partir de utilização de rejeitos. Entretanto, essa produção de biodiesel gera um subproduto, a glicerina bruta, em quantidade aproximada de 10% por litro do biocombustível obtido. Essa alta produção de resíduos traz problemas ambientais se a glicerina bruta for descartada no ambiente sem os devidos cuidados. Entretanto, o aproveitamento desse resíduo exige intensa purificação prévia, que acaba onerando o processo. Neste trabalho, é apresentado um processo simplificado de purificação da glicerina bruta que permitiu aumentar o teor de glicerol inicial, melhorando a viabilidade do processo de purificação. Desta maneira, o reaproveitamento tem o intuito de corroborar com a consolidação do processo sustentável para obtenção do biocombustível pela BERSO fazendo uso do subproduto obtido, o glicerol, que através de um processo de purificação e refinamento da fase bruta gera-se matéria-prima com teor de pureza acima de 80%.

Simple Purification Process of Waste Glycerol from Berso-Ufpe Biorefinary Biodiesel Production: A Sustainable Practice
A B S T R A C T
Experimental Biorefinery of Solid Organic Waste (BERSO) of Nuclear Energy Department of Federal University of Pernambuco (UFPE) produces biodiesel from waste of oils and fats produced at University. This type of biodiesel production appears as an alternative for the production of biofuel from the use of waste. However, this biodiesel production generates a by-product, crude glycerin, in an approximate amount of 10% per liter of the biofuel obtained. This high production of waste brings environmental problems if crude glycerin is discarded into the environment without due care. However, the use of this residue requires intense prior purification, which ends up burdening the process. In this work,a simplified process of purification of crude glycerin is presented, which allowed to increase the initial glycerol content, improving the viability of the purification process. In this way, the reuse is intended to corroborate the consolidation of the sustainable process for obtaining biofuel by BERSO making use of the by-product obtained, glycerol, which through a process of purification and refinement of the crude phase generates raw material with purity content above 80%.
