Foundation Building Materials’ sales fall

15 May 2020

US: Gypsum wallboard distributor Foundation Building Materials reports that sales of wallboard fell slightly to US$202m in the first quarter of 2020.

Gypsum Association releases environmental product declaration type X North American wallboard

15 May 2020

US: The Gypsum Association (GA) has released a revised and updated environmental product declaration (EPD) for 5/8” (1.5875cm) type X North American gypsum boards. Following the standards set in the association’s recently revised product category rules (PCR) for North American gypsum panel products, the EPD provides environmental performance information addressing energy consumption, water consumption, global warming, waste, air emissions and other metrics related to production.

“The Gypsum Association has an ongoing commitment to environmental stewardship. The development and release of this new ISO 21930 compliant, Type III, cradle-to-shipping gate EPD, demonstrates our member companies’ efforts to transparently report environmental impacts as a means of contributing to sustainable design and construction,” said Steve Meima, Leadership in Energy and Environmental Design (LEED) Green Association, executive director of the GA.

Type X gypsum board is commonly installed in commercial, institutional and multifamily/mixed-use facilities. Where fire resistance ratings are required, type X gypsum board is typically specified. The GA has also produced an EPD for glass mat gypsum panel products that will be updated in 2021 under the new PCR.

Talbot works on pilot with South African coal mine to remove gypsum from waste water

15 May 2020

South Africa: Waster water specialist Talbot is working with a coal producer in the Highveld region to remove gypsum generated as a by-product of its mine water purification process.

As part of a pilot project conducted in March 2020, a hydraulic filter press was used to dewater the solids, dry and press them into briquette form for transportation to end-use customers. The remaining filtrate was directed to an evaporation dam before returning to site processes via a blend line. Talbot says it reduced the waste solids from 84 - 2900mg/l and demonstrated that the technology would extract gypsum at a rate of 100kg/hr on a full-scale site operation. Previously the company has used this method on behalf of a South African platinum producer where the recovery of precious metals from a wastewater stream using the same technology.
