Finland: Betolar has signed a cooperation agreement with concrete producer Consolis Parma to develop reduced-CO2 hollow concrete slabs. The development process will implement Betolar's Geoprime binder into Consolis Parma's concrete production. Consolis Parma is committed to halving its CO2 emissions between 2021 and 2035.
Consolis Parma's Technology Director Juha Rämö said “The use of alternative new binder combinations and additives that ensure the efficiency of the manufacturing process are key factors in achieving our climate goals. We are actively seeking new channels to address these challenges. The cooperation with Betolar is an important new partnership for us."

Europe/India: Finland-based Betolar has secured EU-wide and Indian patents for a new waste-based alternative concrete produced without cement and capable of storing energy. Betolar said that the material, which is already patented in Finland, is especially suited for use in renewable energy infrastructure, where it can provide a storage solution for dealing with short-term peaks. Chief commercial officer Ville Voipio said that the company will now seek to establish a partnership for commercialisation of its new alternative building material.
Betolar produces and markets the Geoprime additive used to produce cement-free concrete from supplementary cementitious materials, including ground granulated blast furnace slag (GGBFS), in regions that include India and the EU.

US: Harsco Corporation has changed its name to Enviri Corporation. It says that the new name and brand identity reflect its transformation since the late 2010s into a company that provides services to manage, recycle and reuse waste and by-product materials across many industries. Its subsidiaries - Harsco Environmental, Clean Earth and Harsco Rail - will continue to operate under their existing names as divisions of Enviri.
Nick Grasberger, chair and chief executive officer of Enviri Corporation, said “As we considered where we are today, how our business has evolved and our commitment to the environment, it is important to have a name and brand identity that align with this image.”

71% of German slag recycled in cement production in 2022

26 May 2023
Germany: Building materials research institute FEhS-Institute says that cement producers used 7.9Mt of German ground granulated blast furnace slag (GGBFS) in cement production in 2022. This corresponds to 71% of the 11.1Mt of slag produced by the domestic iron and steel industries during the year. Other applications for the slag included aggregates production (3.1Mt - 28%) and internal recycling at the refinery (500,000t - 4.5%).
Managing director Thomas Reiche said "Unlike recycled materials, iron mill slags are already high-quality and climate-friendly secondary raw materials in their 'first life.' For decades they have made an important contribution to a sustainable recycling economy in Germany. To ensure that this can continue in the future after the transformation of the steel industry, we have been researching new slags together with our partners since 2013 - for example, with the Direct Reduction Of Iron Ore Electric Furnace Slag and Save CO2 projects to develop Blast Furnace Slag 2.0."
