Knauf France aims to use 35% recycled gypsum at Fos-sur-Mer gypsum wallboard plant

20 November 2024

France: Knauf France aims to use 35% recycled gypsum at its Fos-sur-Mer gypsum wallboard plant in Bouches-du-Rhône, with an interim target of 10% by 2025. The company inaugurated the 30Mm2/yr plant in March 2024. It is currently using its own offcuts in production, but has a dedicated silo in which to also store gypsum from other sources in future. The plant’s wallboard requires 15 – 20% less energy than is used at a ‘traditional’ Knauf plant through the use of a vertical mill and high-efficiency driers. Its water use is optimised by drawing it in batches.

Les Cahiers Techniques News has reported that general manager Christine Muscat said "The ramp-up is gradual and we are at a third of production capacity, which we plan to reach fully in the second half of 2025."
