Produção e avaliação energética de biocombustível sólido a partir de resíduos orgânicos provenientes de indústria de revestimentos

Abstract

With the country's productive capacity growing exponentially in the past years, urge to find sustainable ways of producing, since most industries in Brazil use fossil fuels for power generation. Studies on the use of renewable sourcesas a sustainable alternative to replace these fuelsis broad and delivers solutions to the socio-environmental problems as it shows business opportunities and reduction of production costs. The present work aimed to reuse residues generatedby a brown ware industry, such as pallet wood, cardboard and sugarcane bagasse,for the production of solid biofuel through the briquetting process.The residues were divided into five formulations and subjected to compression,under the pressing conditions at 5 ton for 10 minutes in a hydraulic press. After the production of the briquettes, mechanical and immediate analyzes were realizedin order to characterize the biofuel obtainedto determine their energy viability. As to the Higher Calorific Value of 19,94 MJ/kg, 17,56 MJ/kg, 18,62 MJ/kg were found, respectively for the granulometrically characterized formulations 1,2 and 3, 19,14 MJ/kg and 18,64 MJ/kgfor the two formulations without treatment to reduce their particles sizes. In general, the five characterized briquettes proved to be potential energy generators, in different applications. The briquette 1 obtained the best results taking into account the analyzes, showing potential for use in thermal energy conversion processes, showcasing that there is energetic potential through to reuse of industrial organic residues for solid fuels production.
