Gypsum industry news

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.

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.”

Germany: Knauf Gips has partnered with Canada-based lithium hydroxide producer Rock Tech Lithium and waste management company Papenburg Entsorgung Ost to found the Institute for Technologies and Economics of Lithium (ITEL) at Halle (Saale) in Saxony-Anhalt. The institute aims to develop an inter-sector, CO2-neutral recycling economy for lithium in Germany. This will include the use of gypsum from lithium hydroxide production in gypsum wallboard production. ITEL has appointed Martin Luther University Halle-Wittenberg academics Ulrich Blum and Ralf Wehrspohn as its managing directors.

ITEL said “The switch to electromobility will make Germany the central location for battery production in Europe and thus also for the production of the crucial precursor lithium hydroxide. The reduction and reuse of the by-products generated during the refinement of lithium is the focus of the institute's work. Another focus is research into new production steps to optimise by-product value creation.”
