THE CIRCULAR ECONOMY: A CASE STUDY APPROACH CASE STUDY OF THE PRODUCTION OF METALLIZED BRIQUETS AND THEIR USE IN STEEL BLAST FURNACE

Abstract

Purpose: This article aims to bring information about the development and manufacture of metallic briquettes under the circular economy context. Method/design/approach: 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 and tripod of sustainability. Results and conclusion: The metallic briquettes are particularly profitable to use in pig iron production. They are inside circular economy context allow to conclude that use of these briquettes as a part of charge in steel blast furnaces is according with tripod of sustainability. Research implications: The research contributes to practical application of metallic briquettes derived from the agglomeration of co-products in the chain of production of pig iron. From the theoretical point of view, this work contributed to addressing the scarcity of research involving transformation of solid waste into briquettes as a part of charge in steel blast furnace. Originality/value: The results obtained in this study are innovative and relevant to the scientific community, in the context of the use of metallic briquettes as a part of charge in steel blast furnace. The potential performance of metallic briquettes inside circular economy context allow to conclude that use of these briquettes is according with tripod of sustainability.
