US: Oakland, California-based cleantech startup Brimstone has received a US Department of Energy grant worth up to US$189m to establish a plant with a capacity of 80,000t/yr of ‘green’ cement and 20,000t/yr of smelter-grade alumina, according to the San Francisco Business Times. The grant will be paid out in instalments and requires matching funds from new investments, loans and other sources.

The US$378m facility, which is still in the site selection phase, will be located near an existing quarry in order to mine calcium silicate rocks.

CEO Cody Finke said “We’re exclusively looking at brownfield sites. The goal is to build our own plant while utilising existing quarries to ensure a sustainable and economically viable operation.”

Brimstone plans to begin pilot operations in 2025 and aims to have the plant fully operational by the end of the decade. The company is currently testing its decarbonised cement with potential customers from its Oakland research and development facility.

US: The Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management has announced US$101m in funding for five projects to establish carbon capture, removal, and conversion test centres for cement plants and power facilities. The test centres aim to cost-effectively research and evaluate technologies to capture and convert CO₂ into products from utility and industrial sources, or by removing CO₂ from the atmosphere. The initiative aims to reduce CO₂ emissions, promote sustainable technologies and create job opportunities.

Notable projects include the University of Illinois in Urbana, which plans to design a test centre to evaluate carbon management technologies for the cement industry, and Holcim US, which intends to establish a Cement Carbon Management Innovation Centre at its Hagerstown facility in Maryland.

Brad Crabtree, assistant secretary for Fossil Energy and Carbon Management, said “Carbon management technologies such as carbon capture can significantly reduce emissions from fossil energy use and key industrial processes, like cement production. By investing in test centres, we are helping reduce barriers to commercial-scale deployment of carbon capture, conversion and removal technologies that will ultimately help reduce pollution and create jobs.”

US/France: Hoffmann Green Cement Technologies has extended its licensing agreement with Hoffmann Green USA, signed in July 2024, to cover 25 states in the eastern United States. This has triggered an additional entry fee of €8m, following the €2m already received. The agreement grants industrial and technological transfer rights and exclusivity in the expanded territory. It includes fixed and variable royalties based on sales of Hoffmann Green cements. Hoffmann Green USA may also sub-license units in these territories, with discussions currently underway with potential sub-licensees.

Philippines: Aboitiz Upgrade Solar (AUSI), a joint venture between Aboitiz Power and Upgrade Energy Philippines, is building a ground-mounted solar facility at Republic Cement’s Norzagaray plant in Bulacan, according to The Philippine Star. Under the power purchase agreement, AUSI will fund and operate the project, while Republic Cement will exclusively purchase the generated power.

The facility is set to be completed in the second half of 2025, with capacity and project costs undisclosed.

Egypt: Misr Beni Suef Cement has signed a contract worth nearly US$6m with solar energy supplier IRSC, in cooperation with JINKO and HUAWEI, to establish a solar power plant at its site in Beni Suef Governorate.

The project aims to increase the company’s use of clean energy and reduce the environmental impact of its industrial operations. The capacity of the facility has not been disclosed.

China: CBMI Construction has officially launched a flash calcination clay project in Tangshan, Hebei province. Karen Scrivener, head of the Laboratory of Construction Materials at the School of Engineering at the Ecole polytechnique fédérale de Lausanne (EPFL), attended the event. Scrivener is a prominent researcher and advocate for LC3 (limestone calcined clay cement).

CBMI’s other clay projects around the world as a contractor include the SPL Calcined Clay Project in France, the CIZ Calcined Clay Project (rotary calciner) in the Czech Republic, the Guayaquil Calcined Clay Project in Ecuador and the Ivory Coast Calcined Clay Project (flash calciner).

US: Titan America, the US subsidiary of Titan Cement, has filed a registration statement for its proposed initial public offering (IPO) with the Securities and Exchange Commission. The company plans to list shares on the New York Stock Exchange (NYSE), including both primary and secondary sales, aiming to raise up to an estimated US$500m, subject to market conditions.

India: JSW Cement has received regulatory approval from the Securities and Exchange Board of India (SEBI) to proceed with its initial public offering (IPO) after a four-month hold-up since September 2024. The IPO includes a fresh issue of shares worth US$230m and an offer for sale by three shareholders, Apollo Global Management, Synergy Capital and State Bank of India (SBI), worth US$230m combined.

Proceeds from the fresh issue will include US$92.3m for a new cement unit in Nagaur, Rajasthan, and US$83m for debt repayment.

Switzerland: Cement deliveries declined by 4.6% year-on-year to 3.6Mt in 2024, impacted by slow economic recovery, uncertainty and high energy prices, according to industry association Cemsuisse.

However, the fourth quarter of 2024 showed a 2.1% year-on-year increase in deliveries to 0.89Mt, reportedly driven by declining inflation and low interest rates, with Cemsuisse stating that it is ‘cautiously optimistic’ about 2025. The proportion of cement types with reduced clinker content rose to almost 97% from just under 96% in 2023. The proportion of cement transported by rail fell slightly to 37.4% from 37.6% in 2023.

Iraq: Iraq’s largest cement plant in Kirkuk has resumed operations after a shutdown in November 2024 due to environmental non-compliance and an issued fine of US$343,000. Upgrades include a new dust control system and pollution monitoring equipment. Residents of nearby Lailan have previously protested against the plant, stating that the pollution caused adverse health effects and poisoned local crops, according to Intellinews. Following inspections, the factory now reportedly meets relevant pollutant standards.
