ESTUDO DO IMPACTO DO USO DE LODO DE TANQUES DE VINHAÇA SOBRE A QUALIDADE DAS ÁGUAS SUPERFICIAIS

Abstract

Brazil has stood out as one of the key countries in the global energy transition, playing a crucial role in preserving water resources and water quality in its territory. The country is also one of the largest producers of sugar cane in the world, a vital raw material for the production of ethanol, biomass, energy, sugar and other products. The sugar-energy sector, in addition to producing sustainable products, generates by-products and waste that, if not correctly used or managed, can cause environmental and social impacts. This study aims to analyze the environmentally appropriate disposal of sludge from cleaning vinasse tanks and its possible impacts on water courses in the region where this sludge is distributed. To carry out the work, 34 parameters were evaluated, including physical, microbiological and chemical. , obtained over four years of monitoring at eight surface water collection points. For data analysis, statistical techniques were used for comparison, classification and grouping by similarity and literature review of other studies already carried out on the topic. Thus, this study sought to evaluate whether the applications of vinasse tank sludge to the soil, through its long-term incorporation, are capable of causing cumulative effects on the parameters that evaluate the quality of surface waters in streams and rivers close to the areas that receive the application of this byproduct.
