Christian Pfeiffer collaborates with Heidelberg Materials
on the #Carbon4Minerals project to pioneer sustainable
cement production
Christian Pfeiffer Maschinenfabrik GmbH is proud to announce its collaboration with Heidelberg Materials on the groundbreaking #Carbon4Minerals project, aimed at converting CO₂ into value-added building products. This innovative venture, funded by the EU Horizon Europe research and innovation programme (Grant Agreement No. 101091870), will span from January 2023 to December 2026.
As a key participant in this EU-funded research project, Christian Pfeiffer will contribute its expertise to an industrial wpilot plant focused on upscaling enforced carbonation technology. The project involves the mineralization of CO2 in flue gases from clinker production, utilizing Recycled Concrete Paste/Powder (RCP). This process allows for the creation of new low-CO2 composite cements, effectively closing the CO2 cycle in cement production.
The installation site for this industrial pilot is located in Poland, symbolically significant as it is associated with Christian Pfeiffer as a supplier for one of the largest cement grinding units in Europe. The pilot plant will process Recycled Concrete Powder (RCP) at a throughput rate of 1.5 t/a, featuring a Reaction Rotary Drum and Bag Filter. The dimensions of the drum are ø 1.6 x 5.0 m, with a special focus on design flexibility, airtightness, and a moist environment.
The delivery of the plant is scheduled for the summer of 2024. Christian Pfeiffer’s quick understanding of the project needs and their corresponding design has proven instrumental in the swift progress of the collaboration.
The #Carbon4Minerals project is a pioneering effort to address the CO2 footprint in cement production. The Heidelberg Materials and Christian Pfeiffer collaboration aims to set the stage for future replication on a larger scale and in different locations, marking a significant step towards sustainable and environmentally responsible cement manufacturing.
Christian Pfeiffer’s contribution involves delivering the Reaction Rotary Drum and Bag Filter in preassembled condition, providing mechanical engineering expertise, and supervising the erection and commissioning process. The innovative aspects of the solution include the flexibility of the rotary drum for various scenarios, allowing for the optimum RCP reaction. Notably, the design features possible drum enlargement, interchangeable internals, and the displacement of drum chambers.
This collaboration showcases the commitment of Christian Pfeiffer and Heidelberg Materials to spearhead innovations in the cement industry, paving the way for a greener and more sustainable future.
