Resumo
In three years of operation, the waste stock achieved critical levels. All specific waste generations were larger than applications, making the scenario critical in the short term. With the aim of transforming the organization into a more sustainable company, with waste consumption greater than generation, projects were developed to reduce generations by increasing process yields and, projects were developed to optimize the applications of waste now generated. The results of the implemented projects positioned the organization as a national benchmark in terms of metallic yield between the Blast Furnace and Continuous Casting, favoring a reduction in waste generation by up to 30%. Innovative applications for scrap and aggregates were also developed, either recycling to the process and reducing costs, or in several different external industries. Finally, the equalization between generation and application allowed the reduction or even elimination of stocks of all classes existing inside the Plant.
