Heidelberg Materials intends to build a unique and innovative carbon capture unit at its Antoing plant. The so-called Anthemis project (standing for: Antoing Heidelberg Materials Emissions Integrated Solution).

More than 800.000 tons of CO₂ will be captured every year when fully entering in operation around the end of this decade. Heidelberg Materials Antoing will therefore produce clinker (the raw material used to manufacture cement) with a near-zero CO₂ footprint through carbon sequestration.

Thanks to Anthemis, Heidelberg Materials will be able to provide more than 15 million tons of near-zero CO₂ cement to the construction market during the first ten years of the project operation.

Climate change: we're part of the solution

To prevent global climate change, we need to reduce CO₂ emissions. CCS - Carbon Capture & Storage - is a strategic technology for decarbonizing sectors that inevitably emit large quantities of CO₂.

The Anthemis project is an essential contribution to Belgium's transition to net zero greenhouse gas emissions. It is perfectly in line with the carbon-neutral objectives that Europe wants to achieve by 2050.

  • Decarbonization: a driver for sustainable industrial development?

    With 40% of industrial emissions in Wallonia, the cement sector is at the heart of climate challenges. Transitioning to a low-carbon model is no longer optional — it is a necessity. As a pioneer on the path to sustainability, Heidelberg Materials Benelux recently brought together influential voices to reflect collectively on the future of our industry.

    ANTHEMIS carbon capture project reaches a new milestone

    In the first half of 2025, Heidelberg Materials Benelux will submit a permit application for the early renewal of its current operating permit and the construction of a CO₂ capture unit at its clinker plant in Antoing. In this context, a prior information meeting was held on 21 November 2024. The meeting gave Heidelberg Materials Antoing managers the opportunity to explain the clinker production process (the raw material used to make cement) to local residents, and also to present its ANTHEMIS carbon capture project. This information evening also gave the public the opportunity to share their observations and suggestions, or to propose alternatives that could be considered by the company.

    CCS: an essential technology for the transition to net-zero emissions

    The clinker plant in Antoing was the scene of an exceptional event bringing together three major players: Heidelberg Materials, Fluxys and Equinor. By creating a value chain for the capture, transport and sequestration of CO₂ (CCS), these companies are working together to put in place an innovative solution to one of the biggest challenges of our time: climate change.

  • Heidelberg Materials in Belgium teams up with Fluxys Belgium for CO₂ transport infrastructure project

    The cement activity of Heidelberg Materials in Belgium aims to implement the Anthemis project in its Antoing cement plant to meet its carbon emission reduction targets. It is pleased to team up with Fluxys Belgium in order to create a CO₂ value chain. The partners have just signed an expression of interest underlining the cement company's willingness to have access to and use of the CO₂ transport backbone project proposed by the Belgian gas transport infrastructure operator.
