Gypsum industry news

New Zealand: Winstone Wallboards has started despatching wallboard produced at its new Tauranga plant around New Zealand’s North Island. General manager David Thomas said that GIB wallboard products made in the new plant had achieved performance levels consistent with those of wallboard made in the company’s Auckland and Christchurch plants. Earlier in August 2023, Ross Taylor, the chief executive officer of Fletcher Building, Winstone Wallboards’ parent company, said that the Tauranga plant had commenced production. The site is scheduled to become fully operational by the end of October 2023.

Japan: Chiyoda-Ute will add its Chiba gypsum wallboard plant to its ‘green electricity’ mark scheme from September 2023. The certificate from Japan Natural Energy shows that products have been manufactured at a plant using electricity generated from a renewable source. The switch to using renewably-sourced electricity is expected to reduce CO₂ emissions at the Chiba plant by 3800t/yr.

New Zealand: Fletcher Building has managed to grow its earnings for its Building Products division in its 2023 financial year despite a weakened residential market in the second half of the year, poor weather and rising input costs. It noted that “substantial cost increases were absorbed on gypsum, paper, resin and freight, partially offset by lower utility costs from the drop in electricity prices.” It combated this through cost management and ‘pricing discipline.’ Revenue from the group’s Building Products division fell slightly to US$863m in the financial year to 30 June 2023 from US$873m in the same period in 2022. However, earnings before interest and taxation (EBIT) rose by 4% year-on-year to US$120m from US$115m.

Ross Taylor, the chief executive officer of Fletcher Building, said “Our US$240m investment in Winstone Wallboards GIB plasterboard manufacturing and distribution facility in Tauranga has now commenced production and will be fully operational by the end of October 2023. The new plant’s state-of-the-art technology delivers more production capacity allowing for product innovation and future growth.”

Overall the group’s revenue dropped slightly to US$5.07bn from US$5.08bn and EBIT dropped by 29% to US$298m from US$420m. The large drop in earnings was mainly attributed to additional costs allocated to the New Zealand International Convention Centre and Hobson Street Hotel project. Adjusted for significant items the group’s EBIT rose by 6% to US$477m from US$452m.

Germany: Knauf Gips has started an upgrade at its Iphofen gypsum wallboard plant to switch its use of synthetic gypsum to natural gypsum. The project is taking place to prepare the unit for the local phase out of coal-fired power plants by 2038 at the latest. Early work at the site has involved using a 700t crane to lift material over the Würzburg-Nuremberg railway line, during planned renovation to the transport link in late July 2023. The company described the cost of the upgrade as a “mid-double-digit million sum.”
