TO 55 Steel production residues
Jernkontoret's technical area 55, Steel production residues is where companies and institutes interested in research into residual products collaborate.

Parallel with iron and steel products, other materials also are produced which originate in the steel production processes. This takes the form of almost two million tonnes of material (2024), e.g. slag and oxide scale, whereof about:
- 54 % is used externally, e.g. sold as various products
- 27 % recirculated internally
- 19 % becomes landfill waste
Residual products is the collective term for by-products, material for internal circulation, recycling and waste. This term has no legal signification but is one way of summarising everything that arises in addition to the production of steel.
Committee meetings are arranged 3–4 times per year at Jernkontoret or at member companies.

Objectives and purpose of the activity
Goals for technical area 55:
-
To identify potential applications for metallic residual products from steel and metal production in the Nordic countries.
-
To promote the development of new and existing by-products originating from metallic and mineral residual products.
How we work:
-
Increase knowledge of the materials’ properties and value.
-
Prioritise, initiate, and run R&D projects within the field.
-
Promote networking and serve as a forum for knowledge exchange.
-
Monitor technological developments, relevant legislation, and standardization.
How does one become a member of the technical area?
The committee of the technical area decides on acceptance of new members. You are welcome to contact the technical area’s Research Manager if you are interested in participating or if you have questions about activities, membership fees etc.
