Gypsum industry news

Australia: Minotaur has signed a conditional sale agreement on its gypsum deposit at Lake Purdilla on Eyre Peninsula in South Australia. Minotaur will receive US$4.8m in cash for the project, which is 5-15km south of Streaky Bay. The project has a target of 50-60Mt of gypsum. The sale is subject to the unnamed buyer conducting and being satisfied with a study into a port or trans-shipment of the gypsum, plus government transfer approvals.

Minotaur managing director Andrew Woskett said that the sale was part of the company's strategy to divest from industrial minerals and concentrate on copper, nickel and gold. "We've been trying to lighten our exposure to industrial minerals," said Woskett. "That's been proceeding for some time." The sale, which is scheduled to be completed by May 2015, would deliver more than the book value of the project. Earlier studies found that engineering work on a port was viable, but there were now more options, including barging and containerisation.

US: Harrison Gypsum LLC, a producer of gypsum and plaster products, has acquired the Gravel Company LLC, a producer of aggregate materials for the construction industry. Both companies are based in the US. The acquisition will allow Harrison Gypsum to expand its operations in the Eagle Ford region in South Texas.

US: Louisville's Charah Inc uses by-product gypsum from a local coal plant to make a fertiliser, SUL4R-PLUS, which is used by domestic and international farmers. Charah has now announced plans to expand its operations as demand grows.

In April 2013, Charah opened a US$14m plant at Mill Creek Generating Station in Louisville to produce SUL4R-PLUS after recognising a market for it in the agricultural industry. The sulphur content in local soil has fallen significantly in recent years as high-yield farming has pulled more of it out of the ground.

Charah gets gypsum powder from the Mill Creek facility and makes it into fertiliser pellets using several additives. It then sells the pellets to distributors. SUL4R-PLUS is now used in several states, including Texas, Wisconsin, Florida and other countries, including Canada and the Dominican Republic.

Due to its popularity, company officials have stated that they plan to expand operations with the introduction of a second production line at the Mill Creek production facility. In the future, it could also build production lines at other power plants it works with around the country.

UK: Cuddy Recycling Ltd, a start up company that is supported by the Welsh Government, plans to invest Euro1.49m to create the first wood, wallboard and gypsum recycling centre in South Wales. It will create 22 jobs.

Backed by Euro285,000 from the Welsh Economic Growth Fund, the purpose-built centre will be based on the former Wern Works site in Briton Ferry, Neath Port Talbot which, subject to planning, will be partially demolished and redeveloped. The new centre will process and recycle demolition aggregate from construction and demolition projects across Wales, as well as waste timber and wallboard from the construction industry and civil amenity sites.

It aims to provide a green alternative to landfill with waste timber used for animal bedding, panel board manufacture and biomass fuel, with the option of introducing a garden mulch product at a later date.

Aggregates will be sorted for reuse in construction companies. Wallboard will, where possible, be taken back to wallboard manufacture, or the gypsum recycled as a soil conditioner for agricultural purposes. There is also potential for use as a cement additive.

"This project supports two of our key economic sectors, providing a specific service for the construction sector while the new business will operate in the energy and environment industry, one of the fastest growing sectors in the Welsh economy with waste management - the largest sub sector," said economy minister Edwina Hart. "Companies working in this area are not only making a significant contribution in terms of job creation and financial impact, but by reducing waste to landfill they are helping us achieve recycling targets and ensure that we create a sustainable environment for future generations. The proposed new centre will provide an important facility to deal with construction and demolition waste and I am pleased to support this new start up through the Economic Growth Fund."

Canada: CertainTeed Gypsum is reportedly looking at opening a new gypsum mine near Canal Flats. The company currently mines at its Elkhorn Quarry West property near Windermere, which is projected to have between seven and 12 years of gypsum reserves left. The new mine, called the Kootenay West Mine, is projected to employ around 18 people, including drivers. The project start date for the new mine is 2017.
