BIODIESEL PRODUCING INDUSTRIES: CORRECT DESTINATION FOR EFFLUENTS THROUGH THE IMPLEMENTATION OF CLEANER PRODUCTION POLICIES (P + L)

Abstract

Among the current biofuels, biodiesel stands out for the increase in demand in recent years and this situation is a consequence of many advantages, mainly in relation to the environment. In every industrial process, there is the formation of by-products and residues that can become possible environmental contaminants, it would not be different in the production of biodiesel. Among the waste generated in this process, the effluents appear in a prominent place and this massive production ends up generating a large volume. Such effluents present in their composition glycerin, alcohol, traces of the catalyst among others, which prevent its disposal in rivers and soils. In order to carry out the treatment of effluents with the objective of inserting them within the current environmental legislation, producers have encountered many operational, economic and environmental problems. The objective was to present a possible means of mitigating the problem of the destination to be given to the effluent generated by the production of biodiesel, introducing the proposal of cleaner production policies and applying a solution of reuse to the effluents. Adding it to glycerin, which consists of a by-product of low commercial value generated in the production of biodiesel. It is necessary to highlight that the realization of this mixture causes an increase in the volume of glycerin. The results obtained throughout the research showed the feasibility, since there was a considerable decrease in the polluting factors involved in the analyzes.
