Gypsum industry news

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.”

Canada: The Gypsum Association has partnered with Divert NS to support research at Dalhousie University into the use of recycled gypsum from construction waste in concrete production. Dalhousie University previously demonstrated that gypsum could be a viable supplementary cementitious material when combined with fly ash in concrete. In this second phase of research, the team aims to expand on the work to optimise concrete production methods and product quality.

Canada research chair in sustainable infrastructure Pedram Sadeghian said “As durability is important for construction materials, our research group at Dalhousie University aims to study the durability of concrete containing recycled gypsum by monitoring the compressive strength and potential expansion after exposure to selected environmental conditions such as moisture and salt particle penetration that are common for concrete structures exposed to the environment.”

Gypsum Association executive director Stephen Meima said “We are very pleased to join Divert NS in supporting research that may improve numerous environmental outcomes. 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.”

Canada: The Canadian Gypsum Company (CGC) has temporarily closed part of its wallboard plant in Hagarsville in Ontario due to a coronavirus outbreak amongst its employees. Around half of the 250-strong workforce at the site has been sent home, according to the Norfolk & Tillsonburg News. The plant’s mine has also been closed. The company said it had acted "out of an abundance of caution" and it is working with local health services.

Spain: Saint-Gobain Placo has sent its first load of gypsum for 2021 to Montréal in Canada. The shipment consisted of 80,000t of natural gypsum from the company’s Almería quarry. It said that it previously expanded port facilities at Almería to facilitate shipments of this kind. It added that the shipment ‘consolidates the Almería-Montréal trade route,’ supporting the positioning of the Port of Almería as a strategic axis in international maritime trade.

Canada: ScoZinc says that it has increased the gypsum resources at its Scotia mine project in Nova Scotia following a mineral resource estimate. The site has total measured and indicated gypsum mineral resources of 5.18Mt at a grade of 91.8%. Further inferred gypsum resources of 0.79Mt have been recorded at a grade of 91%. The company says that the project has a mining recovery rate of 95% and a cost of US$2/t for gypsum.

Canada: US-based GMS has acquired DL Building Materials. The company distributes gypsum wallboard and other building products to western Quebec and eastern Ontario via two locations in Gatineau, Quebec, and Kingston, Ontario. Founder Richard Davis, general manager Shana Davis and the existing DL management will continue to lead the business. The acquired locations will continue to operate under the DL brand. No value for the acquisition has been disclosed.

France: Saint-Gobain’s says its sales for June 2020 rose by 3.7% on a like-for-like basis as markets recovered from the effects of the coronavirus pandemic. Its sales fell by 12.3% year-on-year on a like-for-like basis to Euro17.8bn in the first half of 2020 from Euro21.7bn in the same period in 2019. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) decreased by 32.4% to Euro1.64bn from Euro2.42bn.

“In a macroeconomic and health environment which remains affected by uncertainties, our earnings growth in June and outlook for the third quarter suggest that our operating income for second-half 2020 will improve significantly on first-half 2020,” said Pierre-André de Chalendar, chairman and chief executive officer (CEO) of Saint-Gobain. He added that the group’s portfolio of products, including those in energy-efficiency and renovation markets, positioned it to benefit from national and European stimulus plans supporting energy saving initiatives.

The group noted a 19.2% year-on-year sales decrease in the second quarter of 2020 due to the coronavirus pandemic, with very different situations between countries and markets. Most of its business segments reported growth in June 2020 with the exception of Asia-Pacific, where the Indian market held the division back. Gypsum sales helped deliver ‘robust growth’ in the US and Canada in June 2020. Strong growth in gypsum was reported in Brazil for the first half of 2020. Chinese sales in gypsum benefitted in the second quarter of 2020 from a new plaster plant, which originally opened in 2019, reaching full production capacity. The group’s High Performance Solutions division reported positive trends from its external thermal insulation solutions (ETICS) products in the second quarter of 2020.

Canada: CertainTeed Canada plans to close its McAdam gypsum wallboard plant in New Brunswick by the end of February 2021. It said that the decision was made after ‘an extensive review of our business,’ according to the Canadian Broadcasting Corporation (CBC). 50 employees are expected to lose their jobs, although the subsidiary of France-based Saint-Gobain says it will try to find roles at other CertainTeed and Saint-Gobain plants for them.
Production will stop at the unit at the end of August 2020. The plant will then continue using inventory until February 2021 with a skeleton staff. The plant was reported to be operating at 22 – 25% production capacity. The closure has been blamed on a decline for wallboard products in the Atlantic Canada region and elsewhere.

Canada: Red Moon Resources says it has restarted production for the season at its Ace mine in western Newfoundland. Overall production at the site in 2020 is expected to be less than in 2019 due to disruption to both operations and markets caused by coronavirus. The situation is expected to stabalise in 2021. The company mined 0.16Mt of gypsum and anhydrite from the site in 2019.

France: Saint-Gobain says that its overall group activity fell to 60% of 2019 levels in April 2020 due to the effects of the coronavirus pandemic. Since then its level of activity surpassed 80% ‘at comparable working days, with large variations by market and country,’ according to Regulatory News Service. The group expects a ‘challenging’ second quarter 2020 before a recovery in the second half of the year. It continues to preserve cash and reduce costs.

In Europe the group reported that, by the end of May 2020, Nordic countries had almost reached 2019 levels. Germany and Eastern Europe were still seeing activity levels below those of 2019. The UK has seen activity levels progress by around 10%/week since a low point in mid-April 2020 when activity were at a ‘virtual standstill’, reaching around 70% of 2019 levels in the last week of May 2020.

In the group’s Middle East & Africa region activity levels surpassed 50% of 2019 levels since a low in mid-April 2020. In France, activity in distribution came close to the 2019 level in the last week of May 2020, but with big differences by region and brand. Spain and Italy are picking up gradually, but remain below the average level of the region. The Netherlands remains close to a normal level of activity, while the Middle East and Africa remain impacted to varying degrees.

North America has reported a ‘contrasting situation state by state,’ but has shown improvement since the low point of mid-April 2020. Activity in May 2020 moved closer to 2019 levels due to ‘significant’ volumes in exterior solutions and a rebound in gypsum volumes. In Latin America, despite the health situation remaining difficult, activity is picking up week after week, from 40% in mid-April 2020 to around 80% in May 2020 with a ramp-up in Brazil.

In Asia-Pacific sales have now reached 2019 levels following the gradual restart of all its production sites in China in March 2020. India remains ‘severely’ disrupted with the restart dependent on the relaxing of confinement measures. The situation is varied across South-East Asia with a rebound in Vietnam where activity has surpassed 2019 levels, but disruptions still relatively significant in Thailand and neighbouring countries.
