Enforced Carbonation Reactor Commissioned by Heidelberg Materials

We are proud to share a significant technological breakthrough within the Carbon4Minerals project: our partners at Heidelberg Materials have successfully commissioned the first continuous-mode enforced carbonation plant at the Górażdże cement plant in Poland.

This facility represents a milestone in the transition from laboratory innovation to full industrial implementation of CO₂ mineralisation technology. At the heart of the plant is the ReConcrete process, an innovative method for transforming recycled concrete paste (RCP) into a low-carbon supplementary cementitious material, while capturing CO₂ directly from cement kiln flue gases without the need for prior gas purification or CO₂ separation. Find out more about the reactor here.

One of the most impactful aspects of this technology is its potential to reduce up to 1,000 kg of CO₂ per tonne of RCP processed. In the coming months, Heidelberg Materials and Carbon4Minerals partners will focus on testing, optimisation, and material validation—further enhancing carbonation efficiency and advancing the development of next-generation composite cements.

This commissioning embodies Carbon4Minerals’ goal: to turn industrial residues into climate-positive resources through practical innovation and cross-sector collaboration.
