NeoCem is a pioneering French company developing low-carbon binders through a patented flash calcination process that transforms construction-site clay into a Portland cement alternative — reducing CO₂ emissions by up to 90% compared to conventional cement production.
NeoCem’s new design, a pioneering company in low-carbon solutions, is revolutionizing the construction industry. Thanks to its patented flash calcination process, it transforms construction-site clay into low-carbon binders, enabling a CO₂ emissions reduction of up to 90% compared to traditional Portland cement.
To bring this vision to life, NeoCem ensures a robust and optimized treatment chain: from clay collection to final processing, thanks to specialized handling, mixing, and dosing equipment, in partnership with WAM to implement a solid and streamlined industrial chain.
The first industrial unit in Saint-Maximin (Oise) will be operational starting in 2025, capable of producing up to 200,000 tonnes of flash-calcined clay per year and avoiding 150,000 tonnes of CO₂ annually.
Why screw conveyors
The screw conveyor solution proved to be the best option, being a closed system with no dispersion into the environment and no contamination from moisture (the clay will need to be stored in a silo).
Additionally, cascading screw conveyors proved more advantageous and cost-effective than pneumatic transport, since no dedusting system is required.
The project confirms WAM’s ability to contribute to the emerging low-carbon construction materials sector, where reliable and contained bulk handling is a critical process requirement.
