Gypsum industry news

US: American Gypsum has received a licence from the Eagle County Board of Commissioners for the expansion of its 336ha Eagle County opencast gypsum mine near Gypsum, Colorado by 12% to 376ha. The Vail Daily newspaper has reported that the expansion will secure the company’s nearby gypsum wallboard plant’s raw material supply until 2046.

Plant manager Chuck Zaruba said “As the state continues to grow, we are an essential product for that to occur.” He added that the producer’s local operations provide more than 100 year-round jobs.

US: CertainTeed plans to establish a new gypsum logistics facility in Jacksonville, Florida. The Saint-Gobain subsidiary plans to integrate a terminal dock operation on the St Johns River with environmental restoration of the riverside at an additional cost of US$70m. The site previously belonged to Kerr-McGee Chemical Corporation until 1978.Construction is due to begin in 2022 and reach completion before 2025. Once operational, the dock will be equipped with a bulkhead, a conveyor, an unloading ramp, truck staging areas and a small office. The site will employ an estimated 32 people.

Vice president and general managerJay Bachmann “We are deeply grateful to the City of Jacksonville for their support of our new logistics facility on the St Johns River, and we look forward to continuing our partnership with Greenfield to ensure the responsible stewardship of this Superfund site.” He added “This project will return a heavily contaminated Superfund site to productive use, creating dozens of full-time jobs and strengthening our company’s ability to serve our customers.”

US: The US Geological Survey (USGS) has reported a 13% year-on-year increase in national calcined gypsum production in the first half of 2021 to 9.57Mt from 8.5Mt in the first half of 2020. The country’s gypsum mines produced 10.1Mt of natural gypsum, down by 3.8% from 10.48Mt in 2021. Synthetic gypsum production remained in line with first-half 2020 levels at 7.2Mt. In total, the US exported 17,900t of natural and synthetic gypsum, up by 8.2% from 16,600t. It exported 49,000t of calcined gypsum, up by 10% from 44,500t.

In the second quarter of 2021, the US exported gypsum wallboard to 29 other countries. Volumes totalled 19Mm2, up by 40% year-on-year. Canada accounted for 95% of gypsum wallboard exports. The US imported 20.9Mm2 of gypsum wallboard during the quarter, up by 54% year-on-year. All imports came from Mexico and Canada, of which Mexico supplied 16.7Mm2 (85%).

UK: British Gypsum has signed the Building a Safer Future (BSF) charter as part of its wider commitment to raise building standards across the construction industry and provide transparency to its customers. The charter comprises five commitments that require registered signatories to put building safety first. The commitments include spearheading change and being the voice of building safety within the industry, being transparent in sharing key information with residents, clients, contractors and other stakeholders, and making safety a key factor when selecting construction partners.

Marketing director Stacey Temprell said “We recognise that becoming a registered signatory of the BSF charter is an important first step towards achieving the culture and behavioural change required in relation to the charter’s objectives around building safety. In confirming our support as a registered signatory, we will now be working to ensure that we embed the principles of the charter into our organisation’s activities.” Temprell added “In addition to signing the Building a Safer Future charter, we are making further improvements to ensure our product and system performance data is always up to date and accurate, so joining like-minded businesses in signing the Charter is a great way for us to demonstrate our commitment to this shift in building standards and put safety first.”

Canada: Dalhousie University, in collaboration with the Canada and US joint Gypsum Association and Divert NS, has entered Phase 2 of its research project into uses of construction and demolition waste gypsum in concrete. The research, continuing until September 2023, will test the durability of various concrete mixes containing gypsum powder recycled from waste drywall. It will examine 81 specimens under three environmental exposures and three exposure durations. The team will use the results to understand the performance and environmental benefits of concrete containing recycled gypsum over the life of a structures. Study leader and Canada research chair in sustainable infrastructure Pedram Sadeghian said that Phase 1 of the study had demonstrated that gypsum could be a viable supplementary cementing material when combined with fly ash in concrete.

Sadeghain said “Our research group aims to study the durability of concrete containing recycled gypsum by monitoring compressive strength and potential expansion after exposure to selected environmental conditions, such as moisture and salt particle penetration, that are common to concrete structures exposed to the environment.”

Gypsum Association executive director Stephen Meima said “The gypsum industry is committed to landfill diversion of construction and demolition gypsum panel waste, and Professor Sadeghian’s work demonstrates that waste gypsum panels may have value beyond their service life in buildings and homes.”
