Utilization of organic sludge in metal industry - OSMet S2

Reference number
Coordinator Swerim AB - Swerim AB, LULEÅ
Funding from Vinnova SEK 10 000 000
Project duration May 2017 - February 2020
Status Ongoing
Venture Challenge-driven innovation - Phase 2 Collaboration

Purpose and goal

Metal and pulp&paper are two largest industrial sectors in Sweden, where the severe environmental concerns such as CO2 emission and residues to landfill arise rapidly and seriously. OSMet project aims to use sludges from pulp&paper, which contain valuable components (carbon and lime), for various metallurgical applications to mitigate theirs climate change, and at the same time to reduce the waste amount to landfill for the pulp&paper industry in a sustainable way. Pilot and industrial trials will be performed to test the newly developed technical solutions.

Expected results and effects

Our target in this project is to replace 5% of fossil fuels, limestone and lime, which are traditionally used metallurgical processes such as blast furnace, cupola furnace and EAF with pulp&paper sludges. The collaborative project will develop solutions with the positive economic potential, and it is expected that the amount of CO2 reduction and reduced sludge to landfill can be up to 270 kton and 350 kton per year with high efficiency by using less fossil fuels (coke and coal) and lime-containing materials.

Planned approach and implementation

The project starts in May 2017, within two years the development work will be conducted both on pilot scale and industrial scale in various production processes within the metal- and pulp&paper industry, to evaluate the methods. The project is coordinated and led by Swerea MEFOS, and other partners are KTH, Outokumpu Stainless, SCA Obbola, SP Processum, SSAB Special Steel, SSAB Merox, Stora Enso, Swedish University of Agricultural Sciences, Swerea IVF and Volvo Powertrain.
