Economia circular: estudo de caso da produção de briquetes metalizados e sua utilização na fabricação de ferro gusa

Abstract

This article aims to bring information about the development and manufacture of metallic briquettes, a product derived from the agglomeration of ore fines and melt shop sludge (solid waste), also known as co-products, and to understand how significant its contribution is in the chain of production of pig iron, what are the relevant factors through which the briquette adds economic value and sustainability for the sector, what is the relationship between this transformation of solid waste into briquettes and the tripod of sustainability. The methodology used will be the case study descriptive category, in which we have: the description, through the expertise of a metallic briquettes Brazilian company, the local context, according to current legislation in Brazil, information on the cost-benefit ratio of briquettes in steel production, and putting an end to the international scene with regard to the so-called circular economy, which addresses the environmental aspects of activities in heavy industry with a view to reducing CO2 gas emissions into the atmosphere. The potential performance of metallic briquettes inside
