Abstract [en]

A description is given on the practice in the Steel Plant of SSAB Tunnplåt AB in Luleå and on the progress in recirculation of residuals and decreasing environmental impact. An extensive study on greenhouse gas in steel production up to slabs was carried out by SSAB during the years 2000-2002. Present and new processes and possible alternatives were studied, as well as the effect of the product programme. Different emission alternatives were studied using global calculation (SSAB + CHP plant). Conclusions on long-term and shortterm possibilities were discussed. Major efforts have been made to develop the process integration technology. In Sweden, this has been realised within a national programme for the total process industry (steel, pulp and paper, petrochemicals, food). There are synergies, as the optimisation problem itself is relatively similar independent of industry sector. Similar efforts are made in other Scandinavian countries and a joint Scandinavian programme has been carried out. Discussions on ore-based vs. scrap-based metallurgy are often based on the assumption that these roads are alternatives to each other. This is not the case; instead, ore-based metallurgy is the first step in a series of subsequent life cycles, and both roads are necessary to carry out the "cycle of cycles". The philosophy of this is discussed. The Scandinavian climate makes the use of residual heat energy for district heating and cooling economically important and a part of energy/sustainability considerations. Significant R&D efforts are and have been made to increase recirculation. Two programmes/ centres of excellence in this field are described.
