Regulatory News:
Hoffmann Green Cement Technologies (ISIN: FR0013451044, Ticker: ALHGR) ("Hoffmann Green Cement" or the "Company"), an industrial player committed to the decarbonation of the construction sector that designs and markets innovative clinker-free cements, today 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.
A partnership to promote the circular economy and decarbonization
This approach reflects the desire of two industries to reduce their environmental impact through innovation and cross-sector synergy. This initiative is a continuation of Norske Skog Golbey's waste recovery and CO2 capture initiatives, aimed at transforming the by-products of its business into valuable co-products for the benefit of other industries. This collaboration also confirms Hoffmann Green's ability to constantly innovate, integrating alternative raw materials and doing so without compromising on the quality of its 0% clinker cements to decarbonize the construction sector.
Following on from this partnership, Norske Skog Golbey will provide Hoffmann Green with a regular supply of fly ash, thus materializing a sustainable collaboration between the two companies.
Julien BLANCHARD and David HOFFMANN, Co-founders of Hoffmann Green Cement Technologies, say: "We are very pleased to have signed this partnership with Norske Skog Golbey, with whom we share the same conviction: the circular economy is a concrete response to the challenges of our time. This partnership demonstrates that cooperation between industries is a fantastic vector for environmental innovation. It also illustrates Hoffmann Green's determination to pursue the excellent environmental performance of its 0% clinker cements through its high added-value Research Development capabilities."
Martine BORTOLOTTI, Responsable Energie/Fluides, Qualité, Environnement et RSE de Norske Skog Golbey, added: "Transforming our waste into resources is central to our environmental strategy. This project demonstrates that, through R&D and industrial synergies, we can build an industrial model that is sober, resilient and sustainable."
