Possibilidades e limitações para utilização de resíduos de couro na produção de pasta de celulose: uma revisão bibliográfica

Abstract

This work highlights the importance of finding effective methods to deal with solid waste in the leather processing industry. By evaluating the possibility of using leather waste in the production of cellulose pulp, considering the significant amount generated in Brazil, one of the main producers and exporters of leather globally, the path is opened for innovative and sustainable solutions. A thorough analysis of articles and patents in this field allows us to understand the feasibility of incorporating leather waste in the production of cellulose pulp, even considering the presence of Chromium VI, a polluting compound. The issue of adequate disposal of this waste, still limited in Brazil, highlights the urgency in addressing the associated environmental risks and impacts. Therefore, an innovative approach is proposed to reuse leather waste from tanneries and footwear industries, aiming not only at sustainability, but also at economic viability. The theoretical research carried out serves as a basis for future practical investigations, focused on effective processing techniques and the effects on the quality of cellulosic pulp. The development of innovative technologies to produce pulp from leather waste not only strengthens the sustainability of the paper and leather industries, but also brings significant economic, environmental and social benefits. With a keen eye on innovation and sustainability, these industrial sectors are transforming to meet the demands of the modern world.
