US: Boulder County has initiated action to terminate the operating licence of the Cemex cement plant near Lyons, Colorado, citing improper expansion of use. Dale Case, director of Boulder County Community Planning and Permitting, sent a notice to the company, motivated by a ‘significant’ rise in traffic. The letter said that the increased traffic created a need for new traffic construction and infrastructure, and requires a new access permit from the Colorado Department of Transportation (CDOT).

The plant has been operational since 1965, but faced changes in 1994 when Boulder County amended its land use code, necessitating special use approval for open mining at the Dowe Flats Quarry. The special use approval for the quarry expired on 30 September 2022, leading to termination of all mining operations and multiple complaints alleging the cement plant's non-compliance with county code and traffic congestion. A CDOT study revealed an increase in truck traffic since the quarry's closure, with daily trips increasing by 50% year-on-year.

Cemex now has a 30-day window to contest the director's determination, reduce plant use, or appeal to the Boulder County Board of Commissioners. The plant will continue operating under existing conditions until a final decision is reached.

US: Eagle Materials and Heidelberg Materials North America, through their joint venture Texas Lehigh Cement Company, will start up a new slag cement facility. The facility will be located in Houston, Texas and will start production in the summer of 2024. When completed, it will have a production capacity of 500,000t/yr. This is in addition to Texas Lehigh’s cement plant in Buda, Texas.

Brazil: Votorantim Cimentos has inaugurated its first unit in Brazil for Viter, its agricultural inputs business, and Verdera, its sustainable waste management business. Located in Itaperuçu, the unit comprises a new Verdera waste crushing plant and an agricultural limestone production line for Viter. This initiative is part of a US$785m investment programme.

Verdera's Itaperuçu facility has a capacity of 48,000t/yr, tripling its previous capability, and is equipped with technology for sustainable waste treatment. The waste processed at the plant will be converted into clean energy for cement production at Votorantim's plant in Rio Branco do Sul, using co-processing technology developed by Votorantim in Brazil in 1991. Viter's new line will increase agricultural limestone production in Paraná. The Itaperuçu plant, along with the existing Rio Branco do Sul unit, brings Viter's total capacity to 1.5Mt/yr of agricultural limestone in Paraná. The new plant features filters for emission control and utilises biomass as a renewable energy source.

US/Austria: RHI Magnesita (RHIM) plans to acquire Resco Group for US$430m. The acquisition of Resco will add fireclay and pyrophyllite-andalusite mining operations in the US to its existing magnesite and dolomite operations across Europe, the US, Brazil and China. Furthermore, RHIM aims to transfer ‘significant’ production volumes from non-US plants to Resco's US facilities. The completion of the acquisition is anticipated in the second half of 2024.
