US: The city council of Glenwood Springs in Colorado is aiming to implement single-haul refuse collection in order to eliminate the dumping of recyclables by 2023, local press has reported. A review of waste management practices found that the city has a recycling contamination rate of just 8%, yet 80% of waste sent to landfill consists of recyclable materials. Eagle County Recycle operates the city's waste management facility. The company says that it supplies waste cardboard for gypsum wallboard backing production in neighbouring Oklahoma.

Manager Jesse Masten said “The mill in Oklahoma that we send the cardboard to actually makes the paper backing for wallboard. Then, that paper backing is potentially sent back to the American Gypsum gypsum wallboard plant in Gypsum and used for the wallboard that they’re producing.”

US: CertainTeed has completed a US$1.3m upgrade to its Nashville wallboard plant in Arkansas to use recycled waste gypsum and paper. The plant will reuse 65,000t/yr of waste materials generated from the production process. The company plans to increase the amount of recycled materials in its gypsum wallboard in the future.

“In Nashville and at our manufacturing sites around the world, we remain laser-focused on reducing waste, reducing our consumption of natural resources, and increasing recycling and circularity throughout our value chain,” said Jay Bachmann, Vice President and General Manager of CertainTeed Gypsum.

US: The US Department of Energy has awarded CertainTeed its 2022 Better Project Award for the company’s installation of a 15,000t/yr production scrap paper recycling system at its Silver Grove, Kentucky, gypsum wallboard plant. The plant recycles ground paper and gypsum from the system in its gypsum wallboard production.

CertainTeed vice president environmental, social and governance North America and Saint-Gobain circular economy solutions managing director Dennis Wilson said "Our recycling technology in Silver Grove allows us to reduce our waste, reduce our consumption of natural resources and also reduce our production costs - all while continuing to produce the best gypsum wallboard product on the market.” Wilson continued “We will continue to look for ways to minimise our environmental footprint while striving to maximise our company's positive impact for our customers and the communities where we operate."

Hungary: Slovakia-based Stavmat Epitoanyag Kereskedelmi has produced its first batch of wallboard from recycled drinks cartons at its Kaposvar pilot plant in Somogy County. MTI – EcoNews has reported that the company plans to install two further production lines at the site by January 2023.

The full-scale plant will cost US$10.6m, employ 20 people and consume 50 – 70t/yr of waste drinks cartons. Stavmat Epitoanyag Kereskedelmi plans to establish a carton collection service across Southern Transdanubia. The present commissioning may lead to the establishment of a second, 10-line plant at a cost of US$21.2m.

Its production and sales volumes of gypsum wallboard increased by 19% to 2.43Bnm² and 18% to 2.38Bnm² respectively. It reported a gypsum wallboard production capacity utilisation rate of 78%. The group added that data from the Gypsum Building Materials Branch of China Building Materials Federation showed that national wallboard production capacity was 4.90Bnm²/yr and that production and sales were 3.51Bnm² in 2021.

Parent company CNBM separately reported that the group raised its average wallboard selling prices by 7%. It said it put up its prices in the reporting period due to high prices of coal, gypsum, paper and other raw materials. Internationally, the group said that a new wallboard plant in Tanzania had started operation in 2021 and that a new plant in Uzbekistan is still being built.

US: CertainTeed has installed new recycling technology at its Silver Grove, Kentucky, gypsum wallboard plant which will enable the facility to divert 15,000t/yr of production scrap paper from landfill. The technology grinds gypsum-contaminated paper into fine pieces for separation. The subsidiary of France-based Saint-Gobain says that it will then be able to reuse both paper and gypsum in its wallboard production at the plant.

CertainTeed’s gypsum general manager and vice president Jay Bachmann said “This project allows us to reduce our waste and reduce our production costs in Silver Grove while also empowering us to increase the efficiency of our use of natural resources.” He added “We will continue to look for ways to minimise our environmental footprint while maximising our company’s positive impact for our customers and the communities where we do business.”
