Avanços para o desenvolvimento sustentável da indústria de papel e celulose através do gerenciamento de seus resíduos

Abstract

Brazil is a highly efficient country for the production of cellulose, which is the basic raw material for the manufacture of paper. In recent years, the country has consolidated itself as the second largest pulp producer in the world and one of the ten largest paper producers. The search for higher quality products and the increasing production of paper and cellulose have resulted in a large amount of waste generated by the industries in this sector, which is an environmental and economic problem for our society. The correct destination of the waste must take into account multiple factors, such as the presence of heavy metals, physical and chemical properties of the pollutants and environmental restrictions. Whenever possible, the use of alternative methods of reusing these tailings is undoubtedly the best solution to be adopted. In this sense, waste can be used as an energy source and / or raw material for the production of other value-added products. Based on this issue, this monograph aims to address trends in improvements in waste management in the paper and cellulose industry, through the valuation of these in biorefineries integrated into factories for the production of biofuels and / or applications in other production processes.
