France: Cemex France and Ecocem have signed a deal to collaborate on the development of reduced-CO₂ concrete development at 10 Cemex France ready-mix concrete batching plants. The partnership will explore methods that include the use of supplementary cementitious materials in place of clinker. Cemex hopes that the collaboration will help to realise its goal of a 55% CO₂ emissions reduction across its European operations by 2030.

Cemex Western Europe vice president materials and Cemex France president Michel Andre said “Cemex continues to reinforce its commitment to advancing the sustainability agenda with the announcement of this extended partnership with Ecocem. We know that if we are to achieve our global ambition of operating as a net-zero business by 2050 we must prioritise exploring innovation and new technologies with like-minded companies who share our dedication to leading the industry’s transition to a lower carbon and circular economy.”

Spain: Cemex España has received clearance from the Balearic Islands Environmental Commission (CMAIB) to import up to 10,000t/yr of granulated blast furnace slag (GBFS) to Majorca. Ultima Hora Online News has reported that the producer will substitute some of the limestone used in the plant's cement production with the material.

Waste management company Tirme previously handled the Lloseta cement plant's slag supply.

US: Charah has opened a slag grinding plant at the Port of Coeymans near Albany, New York. The unit uses the company’s proprietary process to grind granulated blast furnace slag (GBFS) to create supplementary cementitious materials (SCMs). The site is accessible by ship, truck and rail and will sell materials to concrete producers in the northeast of the country.

The new plant will also produce slag cement that is marketed under the MultiCem brand. Slag cement will be distributed throughout Charah Solutions’ MultiSource materials network, a nationwide distribution system of more than 30 sourcing locations that provide ready mix concrete (RMX) producers and other customers SCMs, including fly ash and slag cement.
