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.
Australia: Woodside Energy and Cemex have invested US$6.7m in Melbourne-based KC8 Capture Technologies to support its efforts in achieving net zero emissions via carbon capture and storage.
KC8 is partnering with Cement Australia to construct a commercial demonstration plant in Gladstone, Queensland, aiming to capture 15t/day of CO₂. A partnership with Cemex aims to capture over 100t/day of CO₂ at one of its major plants. Additionally, KC8 plans a commercial pilot at the US Department of Energy’s National Carbon Capture Centre to capture 10-15t/day of CO₂ from natural gas combustion flue gas. The initiative has also secured US$6m from Low Emission Technology Australia and US$11.26m from the US government.
Executive director Greg Ross said "The funds will be used to expand KC8’s team and expedite deployment of its technology into hard-to-abate industries, such as cement – through a number of key projects."
Thailand: Siam Cement Group has awarded JGC Corporation the pre-feasibility study for a carbon capture and utilisation (CCU) facility at a cement plant in Thailand. The study will determine the technology license, assess the required production capacity for CO₂ capture facilities and evaluate the economic feasibility of constructing a CCU facility, which will capture and convert CO₂ from SCG's cement plant emissions into new chemical products.
Germany: Alcemy, manufacturer of low-carbon ‘Cem X’ cement, has raised US$10m to scale up its cement decarbonisation solution. The funding round will support research and development and Alcemy's entry into new markets, including the US, in 2024.
CEO Leopold Spenner said "With this additional nearly US$10m in funding and support from Norrsken VC, in addition to our first-round investors, we're paving the way to a low-carbon construction industry, one project at a time."
Global: Lhyfe and Fives have signed a memorandum of understanding to provide a decarbonised solution for the cement industry, covering everything from hydrogen production to combustion. This initiative is designed to accelerate the energy transition by enabling the use of hydrogen in process industries without the need to modify existing equipment.
Lhyfe will produce and supply green hydrogen, while Fives will offer optimised and safe solutions for its use in industrial combustion processes, including cement production.
Global: Titan Group and Sinoma CBMI have signed a Memorandum of Understanding (MoU) to collaborate on new business opportunities and technological innovations, focusing on decarbonising and digitising cement manufacturing.
Chair of the Titan Group executive committee, Marcel Cobuz, said "Our partnership with Sinoma will enhance our Green Growth Strategy 2026, benefiting both companies and advancing efficiencies across various fronts. Together, we are transforming the building materials sector towards a net zero future."
The MoU extends the collaboration beyond their initial joint venture on Titan's cement plant in Albania, exploring further advancements in low-carbon fuel and cooler technologies, virtual cement applications, digital logistics and carbon capture solutions.
