Cameroon: Cimpor has inaugurated its new plant in Kribi, Cameroon. Following investments in Côte d'Ivoire, Cimpor embarked on this greenfield project in February 2020, integrating the ‘world's first’ operational flash calcined clay production line, launched on 29 October 2023.

Cimpor Cameroun now has an output of 1.2Mt/yr of cement and 0.4Mt/yr of calcined clay. Cimpor's calcined clay production technology - ‘deOHclay’ – reportedly saves up to 80% in CO₂ emissions, up to 35% in electricity consumption and up to 40% in thermal energy consumption per tonne. Compared to a plant with a similar capacity, this technology could reduce CO₂ emissions by around 0.2Mt/yr, according to the company. The new plant will reduce the country’s dependence on imports to meet local cement needs.

Mexico: Regenera, a subsidiary of Cemex, has launched a pilot project at its Broquers Ambiental plant in Querétaro to transform the city’s organic waste into alternative fuel using a drying process known as ‘biosecado’. This initiative makes Querétaro the first zero waste municipality in Mexico, according to the company. The plant now processes almost 90% of the municipality’s waste, transforming over 8000t monthly into biomass to reduce the amount of material sent to landfill.

Vice president of urban solutions at Cemex Mexico, Antonio Balmori, said "This project that we started today at our Broquers Ambiental plant excites me very much because it will take the city of Querétaro to the next level in waste management, where we will seek to take advantage of 100% of the urban solid waste generated in the municipality."

France: Irish cement producer Ecocem plans to industrialise a new technology that will be implemented at its Dunkirk site in northern France by 2025. The technology, called ACT, replaces clinker with limestone filler to reportedly reduce the carbon footprint of cement by 70% compared to the average French cement.

The company is relying on public funding from Bpifrance, the Hauts-de-France region and the urban community of Dunkirk.

US: Holcim US in Missouri will receive US$1.37m from President Biden's Inflation Reduction Act to support the reduction of climate pollution in manufacturing construction materials, as announced by the US Environmental Protection Agency (EPA). The grant is part of a broader effort to reduce emissions from the manufacturing industry and will aid Holcim's Environmental Product Declaration Accelerator Project.

EPA Region 7 Administrator, Meg McCollister, said "We commend Holcim for its work in advancing sustainable practices to reduce carbon emissions here in the Heartland and across our nation. Its innovative approach, supported by this grant, advances climate-friendly practices and sustainability in one of our nation's most important industries."

Canada: Minister of Environment and Climate Change, Steven Guilbeault, announced the reinvestment of up to US$1.6m from industrial pollution pricing proceeds into a new emissions reduction project at St Marys Cement in St Marys, Ontario. This initiative will involve the installation of a new kiln utilising low-carbon fuels, including discarded plastics, to reduce the use of carbon-intensive fuels used in the manufacturing process by up to 30%. The project aims for a reduction of over 39,900t of greenhouse gas emissions by 2030, according to Foreign Affairs news.

Denmark: Aalborg Portland, a Danish cement firm, has completed testing for its second carbon capture pilot plant and will now undergo further trials in Romania and Greece, according to M-Brain News. This plant is a key component of the EU-subsidised ConsenCUS project.

A spokesperson for Aalborg Portland said "This experience offers preliminary knowledge ahead of establishing a full-scale CO₂ capture facility, and we are also contributing to the progression of this area where we, within the ConsenCUS collaboration, have verified the existence of multiple potential technologies for CO₂ capture."

US: Vineyard Offshore has agreed to buy 2000t of cement from Sublime Systems, a Massachusetts startup planning a US$150m ‘carbon-free’ cement plant in the city. The cement will be used for turbine platforms and onshore civil works within the Vineyard Wind 2 project, aiming to reduce its carbon footprint. This agreement is contingent on the project's selection in upcoming solicitations.

Germany: Cemex Deutschland has partnered with recycling service provider Alba to construct a new biochar production facility at its Rüdersdorf cement plant in Brandenburg. Named ALCE, the project will utilise biogenic waste to produce biochar, aiming to reduce greenhouse gas emissions from cement production. This initiative is part of the Carbon Neutral Alliance, targeting carbon neutral cement production at Rüdersdorf by 2030.

South Korea: South Korean cement manufacturers recently convened at an event hosted by the Korea Cement Association and the Korea Industry Alliance Forum to discuss how to achieve carbon neutrality. The industry currently faces financial challenges in upgrading equipment due to low cement prices. However, it has achieved a 20% decrease in greenhouse gas emissions per tonne of cement since 2014, aided by the use of alternative fuels and investment in energy efficiency. The Korean government now requires that greenhouse gases be cut by 12% by 2023 from 2018 levels by 53% by 2050.

The industry currently uses post-consumer plastics as fuels instead of fossil fuels and incorporates byproducts from other industries, like sludge. However, some environmental groups have labelled cement made from industrial byproducts as ‘garbage cement’ claiming it contains hexavalent chromium levels more than four times the EU’s allowable limits. The use of plastics as alternative fuel has also sparked complaints from local waste collection and incineration companies, who argue that cement companies are taking away their business.

Professor Kim Jin-man from Kongju National University said "We also need to focus on developing high-performance clinker, advanced chemical admixtures for concrete, and accelerators that shorten concrete curing times."

Croatia: Holcim Croatia's €237m 'KOdeCO' project has been declared a strategic investment by Croatia. This will reportedly make Holcim the first producer of carbon-neutral cement in Croatia and one of the first in Europe, according to a press release by the company.

In January 2024, Holcim Croatia began implementing the carbon capture and storage project at the cement plant in Koromačno, signing a contract with the European Climate, Infrastructure, and Environment Executive Agency and securing a grant from the EU Innovation Fund totalling €117m. The project will reduce annual CO₂ emissions by 367,000t/yr.
