Hoffmann Green Cement and Norske Skog Golbey transform paper ash and recycle it into resources for the manufacture of 0% clinker cement

Hoffmann Green announces the signing of a strategic partnership with Norske Skog Golbey, a key player in the recycled fiber paper industry and France’s leading paper recycler. This innovative, cross-sector collaboration aims to integrate ash from the paper-making process into the production of Hoffmann Green’s 0% clinker cement. This process marks a new step towards the decarbonization of industrial sectors and enables residual resources to be optimized.

When paper ash becomes a co-product in the production of carbon-free cement

Since January 2024, teams from Norske Skog Golbey and Hoffmann Green Cement have been combining their expertise to convert a by-product of the paper-making process: ash from the incineration of paper production residues. After several phases of laboratory testing and then in real-life conditions, the results have proved conclusive. In May 2025, the shipping of a tanker full of ash validated the use of this new material on an industrial scale in the formulation of Hoffmann Green’s 0% cement clinker, paving the way for its deployment on future construction sites.
