CertainTeed Canada gains approval for Antrim gypsum mine in Nova Scotia
Canada: CertainTeed Canada has received environmental assessment approval from the Nova Scotia Department of Environment and Climate Change for its Antrim Gypsum Project in Halifax County, Nova Scotia. It can now move to the project’s permitting phase and toward construction beginning in 2026.
The subsidiary of France-based Saint-Gobain intends to establish operations in Nova Scotia, where eastern North America’s only known major source of gypsum is located. The company will then strengthen its ability to supply its wallboard plants in eastern Canada and the US with locally mined gypsum.
CertainTeed Canada also recently completed construction on its Kootenay West Mine in British Columbia, which is now operational at full capacity with plans to develop a new railway to connect better to other units in western Canada. The company is also reopening its Amaranth Mine in Manitoba to serve central Canada. These efforts are in addition to a partnership with New West Gypsum to recycle and reuse wallboard in production in Alberta, British Columbia, Manitoba, Ontario and Quebec, which has led to over 1Mt of wallboard being recycled and reused at the Vancouver plant alone.
Knauf France aims to use 35% recycled gypsum at Fos-sur-Mer gypsum wallboard plant
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."
