It was previously installed at a production site in Germany. Dismantling is underway, with delivery to the plant in Paraguay scheduled for mid-2026.

Canada: Saint-Gobain subsidiary CertainTeed has concluded a year-long trial to increase the efficiency of CertainTeed 5/8 Type X gypsum wallboard production at its Winnipeg plant through recipe optimisation and technology upgrades.

It cut water usage by 1.09 million litres (3%), energy consumption by 25,000MWhr and CO₂ emissions by 5.6t year-on-year, while also increasing productivity by 5% year-on-year.

The producer now plans to roll out other water management initiatives based on the case study of the Winnipeg plant across its plants in Calgary, Montreal, Toronto and Vancouver.
