Abstract Summary

The metal industry is facing environmental regulations leading to more and more efficient off-gas systems. These off-gas systems generate additional by-products in the form of dusts and sludge. The “Go-4-0” project has for objective to agglomerate by-products from different sectors in view of their recycling in the production of FeMn alloys.

Full Abstract

The metal industry is facing ever stringent environmental regulations leading to more and more efficient off-gas systems. These new off-gas systems generate additional by-products in the form of dusts and sludge. At the same time, the quality and scarcity of raw materials is becoming a real issue and metal producers have to maximize their resource efficiency in order to maintain their competitiveness. Therefore, a cross-sectoral consortium has been built in the frame of an EIT Raw Materials project “Go-4-0”. Its objective is to agglomerate by-products from different sectors in view of their recycling in the production of FeMn alloys . The Go-4-0 project is focused on market specifications (product, use, value) and on the technological and economic viability of the proposed recycling chain. Each step of the Go-4-0 project aims at minimizing the importance of OPEX and CAPEX for the innovative industrialization solution that will be found out. In 2016, a first market study was performed to define the best mix in terms of economic value versus process feasibility.
Laboratories results have been carried out. Several binders have been tested and optimized in order to minimize the cost of cold pre-processing while providing the required mechanical properties. Several tests have been compared in order to determine the best recycling route. The final feasibility assessment will be done in 2019 during a semi-industrial campaign using a 600 kW Smelting Arc Furnace.
