France: The Scientific and Technical Center for Building (CSTB) has certified Hoffmann Green Cement Technologies’ clinkerless H-UKR alkali-activated slag cement for structural use in buildings of all types. BusinessWire News has reported that the certification confirms the product’s safety, sustainability, lifespan and performance in conformity with Eurocode 2 and Eurocode 8 design standards.

Co-founders Julien Blanchard and David Hoffmann said “In the midst of ongoing frenetic communication regarding carbon neutrality, Hoffmann Green Cement is as usual endeavouring to back its announcements with verified and evaluated elements. The granting of these evaluations further objectifies the quality of our cement, notably with the awarding of a lifespan of 100 years. In this regard, we would like to thank the CSTB’s teams for drafting this unprecedented technical appraisal and our own teams who are working tirelessly on seeking innovative decarbonised solutions to preserve tomorrow’s world.”

South Korea: Continental New Materials has awarded a granulated blast furnace slag (GBFS) supply contract to steel producer POSCO. Continental New Materials applies technology developed at the Ulsan National Institute of Science Technology (UNIST) to produce clinker-free cement.

POSCO's hot rolled and wire rod marketing manager Kim Dae-Up said "We will continue to provide support so that POSCO's steel by-products can become eco-friendly cement materials and contribute further to carbon reduction."

France: ArcelorMittal has discussed the role of slag in the circular economy at a recent media event in Paris. Alan Knight, head of corporate responsibility, described how steel plays a key role in the circular economy, at a time when the European Union is debating its Circular Economy Package, which includes revised legislative proposals on waste. He detailed a number of projects at ArcelorMittal that are using waste created during the steelmaking process including turning steelmaking slag into agricultural fertiliser as well as making bioethanol to fuel aeroplanes from waste gases created during the steelmaking process.

“At ArcelorMittal we are active in being involved in a number of different partnerships that look to more fully utilise and exploit the potential from re-using by-products and waste gases. We are fully supportive of the concept of carbon capture and utilisation and convinced that this offers an important long-term opportunity for the reduction of CO₂,” said Knight.

Key topics discussed at the event included the effects of Chinese steelmaking overcapacity upon the European industry. David Clarke, ArcelorMittal’s head of strategy and chief technology officer, said that imports of steel are effectively ‘swallowing’ up a slow increase in European steel consumption since the market crash in 2009. However, Europe Flat Products chief executive officer Geert Van Poelvoorde added that the European steel industry could prosper under the right legislative framework.
