Gypsum industry news

France: Etex subsidiary Siniat plans to install a new boiler, fired by either solid recovered fuel (SRF) or waste wood, at its Auneuil gypsum wallboard plant in Oise Department. The producer expects this to reduce the plant's gas consumption by 20%. The L'Usine Nouvelle newspaper has reported that the project is part of a planned Euro30m sustainability overhaul of equipment at the plant before 2026. Siniat recently brought the Auneuil plant back online following the installation of a new Euro15m dryer in early 2023, which increased wallboard drying times by 10% and reduced gas consumption by 20%. The producer said that this has eliminated 5900t/yr of CO₂ emissions.

From the remaining Euro3m of its allotted budget for sustainability upgrades, Siniat will build a gypsum recycling plant at the Auneuil gypsum wallboard plant. It currently receives its recycled gypsum from Ritleng Revalorisations' gypsum recycling plant in Rohr, Bas-Rhin Department. Currently, natural gypsum from the Le Pin-Villeparisis and Montmorency mines accounts for 40 - 60% of the Auneuil plant' gypsum consumption.

US: The US gypsum wallboard industry produced 623Mm² of gypsum wallboard during the first quarter of 2023, down by 1% year-on-year and by 1.2% quarter-on-quarter. The industry exported 20.1Mm² of gypsum wallboard in the quarter under review, corresponding to 19% year-on-year growth. Canada received 19Mm² of the product, 94% of total exports for the quarter.

United States Geological Survey (USGS) data show 4% year-on-year growth in US gypsum wallboard imports. The country imported 23Mm² during the year, 20.9Mm² (91%) of it from Mexico and 1.84Mm² (8%) from Canada. Total calcined gypsum consumption was 4.66Mt in the US in the first quarter of 2023, up by 9.9% year-on-year from 4.24Mt in the first quarter of 2022.

New Zealand: Winstone Wallboards says that it successfully started a test run on the new production line at its new Tauriko gypsum wallboard plant in mid-May 2023. In a statement general manager David Thomas said “The team successfully put ‘slurry on paper’ and ran board down the line and, beyond our initial plan, through the dryer.” He added the company was confident that it would be producing wallboard in the second half of 2023.

Japan: Chiyoda-Ute is preparing to launch a gypsum board product, Chiyoda Circular Gypsum Board, from June 2023 that uses 100% recycled gypsum. The company says it is the first product of its kind in the world to use 100% waste gypsum board collected from construction sites. Manufacturing will also be carbon neutral through the use of wood chips to heat the plant’s boiler and electricity supplied from renewable sources.

Japan: Yoshino Gypsum has developed a new gypsum wallboard fixing method called ‘Smart JG’ that uses adhesive and a magnet. It is intended to replace the usual installation method using power tools, screws and nails. The Smart JG method uses a special tape-like solid adhesive ‘JG02’ and a special tool ‘Super Mag Chuck’ to fix boards to the iron base and layer them. Notably, this new approach does not use screws and does not have staple marks on the surface of the board allowing for more decorative applications. This method is also quieter as power tools are not used. The patent for ‘Smart JG’ is currently pending.
