Abstract
Circular Economy in EAF Process: How to Make It Sustainable with Zero Waste Project in Ferriere Nord
Highlights
At a distance of 20 years since "Zero Waste" project started, we can state that all secondary materials have been reviewed and re-evaluated in a circular economy perspective
The new developed materials replace natural ones that otherwise should be extracted from mines or quarries: basalt, porphyry, limestone, iron ore, zinc and lead minerals are replaced with products obtained from slags of Electric Arc Furnace (EAF) and ladle furnace (LF), from EAF dust, from iron scale and refractories
In this paper we describe our experience in the transformation of our business from a linear economy to a circular one related to slags, dusts, iron scale and spent refractories
Summary
At a distance of 20 years since "Zero Waste" project started, we can state that all secondary materials have been reviewed and re-evaluated in a circular economy perspective. The new developed materials replace natural ones that otherwise should be extracted from mines or quarries: basalt, porphyry, limestone, iron ore, zinc and lead minerals are replaced with products obtained from slags of EAF and LF, from EAF dust, from iron scale and refractories. We established an important and stable relation with many users of these new products, creating a network that trusts on regular availability and quality of them. In this paper we describe our experience in the transformation of our business from a linear economy to a circular one related to slags, dusts, iron scale and spent refractories
