India: The National Green Tribunal (NGT) has directed the Haryana State Pollution Control Board (HSPCB) to collect details of all ready-mix concrete plants in Haryana and verify whether they are complying with environmental norms. The NGT also directed the HSPCB to take action against any non-compliant plants.

The Tribune newspaper has reported that a joint committee including the HSPCB and local district magistrate previously found 21 ready-mix concrete plants operating in violation of environmental regulations near Dadlana, Panipat.

US: Urban Mining Industries has completed deliveries of its Pozzotive ground glass pozzolan binder for JPMorgan Chase’s global headquarters in New York. The company produced the binder from post-consumer glass feedstocks at its Beacon Falls plant, and supplied it to SRM Concrete for mixing at its Long Island City ready-mix concrete plant. The building contains 39,700m³ of concrete featuring Pozzotive binder in place of 40% of its cement content.

Contractor Severud Associates said "This innovative use of recycled glass instead of ordinary Portland cement not only saved over 5000t of embodied carbon and diverted more than 29 million glass bottles from landfills, it also enhanced the strength of the concrete."

US: Maschmeyer Concrete subsidiary Redwing Materials has appointed Gebr. Pfeiffer to build a slag grinding plant at Port Redwing in Tampa, Florida, according to S&P Global Commodity Insights. When operational in early 2027, the plant will produce ground granulated blast furnace slag to replace cement in concrete production. It will use Gebr. Pfeiffer’s ready2grind grinding system with a four-roller MVR vertical roller mill, designed to withstand Florida's coastal weather.

UK: Holcim UK has demonstrated a new low CO₂ cement formulation made from recycled concrete fines (RCF) in a cross-industry trial funded by Innovate UK and led by the Materials Processing Institute (MPI). Beginning in September 2024 and concluding in December 2025, the project brings together industry bodies, engineers and researchers to develop an RCF-based cement as a lower-carbon alternative to ordinary Portland cement. The producer poured a demonstrative batch of ready-mix concrete using the new formulation at its Whetstone plant in Leicestershire. The concrete used CEM II cement, with RCF replacing 20% of clinker without compromising production feasibility. The cement will undergo further testing and certification before it can be written into the revised British Standards for concrete in 2027. Holcim said that plans are already in place to source RCF from its waste management partner, and the waste stream will be put back into production at its new cement plant in Tilbury, expected to be operational from late 2026.
