UK: Material Evolution has secured a venture debt facility from HSBC Innovation Banking UK to support the development and scaling of its ‘ultra-low CO₂’ cement technology.

The producer uses alkali fusion and AI-powered design to manufacture its MevoCem product, which the company says reduces CO₂ emissions by up to 85% compared to ordinary Portland cement. The venture debt facility will reportedly be used to help ‘grow the company’s commercial traction’, according to a press release.

Spain: Molins has received permits from the Generalitat de Catalunya to begin operating an auxiliary hydrogen generation facility at its Sant Vicenç dels Horts cement plant in Barcelona.

The producer will install a hydrogen production module based on water electrolysis, using water from subway catchments. The system includes osmosis treatment to purify the water prior to splitting it into hydrogen and oxygen using renewable electricity. The hydrogen will be consumed directly as fuel in the clinker kiln, replacing part of the petcoke currently used to reduce CO₂ emissions.

Molins forecasts hydrogen consumption of 305t/yr and expects to cut CO₂ emissions by 3600t/yr. The company said the project supports its Sustainability Roadmap 2030, which targets a 20% reduction in emissions by 2030 compared to 2020.

Vietnam: The government will allocate greenhouse gas emission quotas to cement and steel plants and thermal power facilities by 31 December 2025, following a new decree issued on 9 June 2025, which takes effect on 1 August 2025. These facilities will receive quotas during the 2025–2026 period. The Ministry of Agriculture and Environment, in coordination with the ministries of industry and trade and construction, will lead the pilot proposal process and submit total allowable emissions to the prime minister for approval. Quotas for each plant must be finalised by the end of 2025. From 2027, ministries will propose lists of facilities and quotas for 2027–2028 and 2029–2030, with submissions due by 30 June of the first year of each period. The Ministry of Agriculture and Environment will allocate quotas by 31 October annually once approved.

Quotas will be based on emission intensity per unit of product, industry growth targets and each facility’s potential to reduce emissions. Facilities may trade quotas and carbon credits on the national market. The decree also revises rules on trading, borrowing, transferring and surrendering quotas. Facilities must surrender quotas equal to verified emissions, minus carbon credit offsets, by 31 December following each compliance period. Penalties and future deductions will apply to those who fail.

US: Ozinga has broken ground on a 1Mt/yr alternative cement grinding plant in East Chicago, Indiana. The plant is equipped with a Gebr. Pfeiffer MVR5300-C6 vertical roller mill. It will produce ASTM C989-compliant slag cement and other blended cements. When operational in 2026, it will be the largest of its kind in North America, and avoid 700,000t/yr of CO₂ emissions from conventional cement production. Its location offers strategic rail, road and shipping access to large markets in the US and Canada.

East Chicago Mayor Anthony Copeland welcomed an anticipated 150 new jobs resulting from construction and subsequent operations at the plant.

India: During the fourth quarter of the 2025 financial year (which ended on 31 March 2025), premium products constituted 16% of Shree Cement’s sales mix, up from 12% one year previously. During the period, the company further diversified its offering with the launch of two new premium cements, Bangur Marble Portland slag cement and Extra White Portland slag cement, in Bihar, Jharkhand and West Bengal. Both products are designed for maximum brightness and smoothness within their category of CEM-II Portland slag cements. The company says that its growing portfolio helped it to increase its full-year financial realisation per tonne by 5% year-on-year.

Business Today News has reported that managing director Neeraj Akhoury said "In the 2025 financial year, 74% of our cement output was blended, avoiding over 7.2Mt of CO₂ emissions."

Shree Cement crossed 60% consumption of energy from renewable sources in May 2025, Construction World News has reported. It has 582MW of installed renewable power capacity and is currently in the process of building a 1MW battery storage system at one of its cement plants in India.

UK: Holcim UK will roll out Fuelre4m’s Re4mx fuel reforming technology across more than 200 sites nationwide, following three years of testing that the company says improved fuel efficiency and helped reduce emissions across operations.

Holcim UK supply chain director Edern Lalanne said “This agreement is the result of meticulous testing, collaboration and operational learning. We have seen consistent results with Re4mx across a wide range of use cases, and it aligns directly with our commitment to sustainable innovation and operational excellence. This is about measurable outcomes, not promises, and Fuelre4m has delivered both the data and the support to back it up. This is part of our mission to make sustainable construction a reality and continues our journey to achieve net-zero by 2050.”

Re4mx will be delivered in pre-measured containers and dosed directly into on-site fuel systems. Holcim says that the rollout has been designed for ease, speed and zero disruption to infrastructure or workflows. Manufacturing is underway, with shipments to the UK beginning once production is complete. From there, Re4mx will be distributed site-by-site across Holcim’s network, through Fuelre4m’s VIRDIS (Virtual Distribution) system, in preparation for full dosing from 1 September 2025.

France: Ecocem will invest €170m to build four new production lines for its ACT low-carbon cement technology in Fos-sur-Mer and Dunkirk. This follows a €50m investment at Ecocem’s Dunkirk facility to deliver its first production line. The additional manufacturing capacity will come online between 2028 and 2030. At full capacity, ACT production in France will reach 1.9Mt/yr, reducing CO₂ emissions by 800,000t/yr and creating 60 jobs. The French government has reportedly committed to working closely with Ecocem to identify operational and financial solutions to accelerate and deliver the expansion.

Ghana: CBI Ghana and joint venture partner Heidelberg Materials have commissioned the ‘world’s largest’ calcined clay plant in Ghana, according to an announcement by the German producer. The plant has a capacity of 400,000t/yr of calcined clay and uses local raw materials to reduce reliance on imported clinker.

Hakan Gurdal, member of the managing board of Heidelberg Materials, said “Based on calcined clay technology, we can now extend our offering of innovative, high-quality cement products, while reducing CO₂ emissions and utilising the rich local resources. The project has created over 300 local jobs."

Spain: A local cement manufacturer will integrate ‘green’ hydrogen into its production process using a 2MW Neptune II electrolyser from Uk-based supplier ITM Power, according to H2 View news. The electrolyser will supply hydrogen to be co-fired with natural gas in the cement kiln, expected to reduce CO₂ emissions. The method was previously demonstrated in 2021, when Hanson UK (now Heidelberg Materials) and MPA trialled hydrogen co-firing in cement production. It will be the first time that ITM has deployed the system in the cement industry.

Oman: Raysut Cement is reactivating a partnership with China's Sinoma Overseas Development to launch Oman's first waste heat recovery (WHR) power plant at its Salalah site, according to the Oman Daily Observer. The groundwork for the 9MW facility was originally laid in 2018. Once operational, the facility is expected to reduce the plant’s reliance on national grid power by up to 30% and reduce CO₂ emissions by more than 50,000t/yr. Engineering design and site preparations are expected to be revisited before the end of 2025.
