India: Holcim has agreed to sell its Indian business to industry, energy and ports conglomerate Adani Group for US$6.37bn. The assets consist of a 63% stake in Ambuja Cement, which in turn owns 50% of ACC, and a 4.5% direct stake in ACC.

ACC and Ambuja Cement employ 10,700 people and operate 31 cement plants in India. The deal will make Adani Group India’s second-largest cement producer.

Chair Gautam Adani said "With Holcim's global leadership in sustainability, we are acquiring some of the most efficient building materials operations in India, powered with clean technologies like heat recovery systems. We recognise that Ambuja and ACC operations are energy intensive and therefore, when combined with our renewable power generation capabilities, we gain a big head start in the decarbonisation journey that is a must for Indian industry."

Holcim says that its focus is now on expanding its solutions and products business. Reuters News has reported that the group plans to put the proceeds of the assets’ sale towards lower-carbon acquisitions. Its Indian operations contributed 26% of group CO₂ emissions.

CEO Jan Jenisch said "We will always make cement, but we will decarbonise cement.” He added “We are happy to build up other segments like building solutions and products."

UK: Hanson has signed a memorandum of understanding with Shell to work together to explore opportunities that help the construction industry’s transition to net zero emissions.

Huaxin Cement’s Huangshi subsidiary put together its application based around a waste heat recovery project. It then worked with the Bank of Communications and the People's Bank of China. The cement producer says that its other subsidiaries are now working on similar applications.

Vietnam: ThyssenKrupp Industrial Solutions Vietnam (TISV) and the Vietnam Institute of Building Materials (VIBM) have signed a memorandum of understanding on cooperation between both parties on the research and application of new technologies towards reducing the CO₂ emissions of cement production. At the signing ceremony, Lukas Schoeneck, the chief executive officer of TISV confirmed his commitment to collaborate with VIBM, under the guidance of the Deputy Minister of Construction Nguyen Van Sinh. The parties now plan to identify a lighthouse project that will use alternative fuels in response to an increase in the global price of coal.

Pham Van Bac, Head of the Building Material Division at the Ministry of Construction, said that Vietnam is implementing the a strategy for the development of building materials for the period 2021 - 2030, with a vision to 2050. The plan for the cement industry is to limit the use of natural resources, reduce greenhouse gas emissions and save energy while promoting the maximum use of waste streams from industries and domestic sources as raw materials in cement production.

World: The Global Cement and Concrete Association (GCCA) has named its first six startups to receive backing under the inaugural Innovandi Open Challenge. The startups have partnered with GCCA members to help increase cement’s sustainability towards achieving net zero CO₂ concrete production by 2050. This will lead to the formation of six consortia to further test, develop and deploy their new technologies.

Carbon capture, utilisation and storage (CCUS) startups CarbonOrO, MOF Technologies and Saipem, all based in Europe, are among the participants. GCCA members are currently involved in dozens of pilot projects and aim to have 10 industrial-scale carbon capture plants installed by 2030. Other startups Carbon Upcycling Technologies and Fortera, from Canada and the US respectively, use captured CO₂ to produce low-carbon cement and cementitious materials, while UK-based Coomtech has developed a low-cost drying technology using turbulent air.

GCCA CEO Thomas Guillot said “It’s a proud moment to see the industry coming together to support such innovative start-ups on their journey. Our member companies were greatly impressed by their ambition to be a key part of the climate solution. The programme is another big step forward towards unlocking innovation to help us achieve our net zero goal.” He continued “As the need for resilient and sustainable communities to support a growing global population becomes more pressing , cement and concrete will be essential to providing the infrastructure and buildings that society needs. Achieving net zero concrete relies on a number of different groups playing their part, and as an industry we’re looking outwards as well as inwards, to see how start-ups like these can support our goals.”

Mexico: Cemex intends for its Vertua products to account for over half of all of its cement and concrete sales by 2025.
