Gypsum industry news

India: The Central Salt Marine and Chemical Research Institute (CSMCRI) has standardised and internationally patented a novel process of converting discharge emanating from soda ash and salt-making units into value-added products, including the extraction of far more gypsum than previously possible.

"A novel cost-effective process that helps derive three times more gypsum from the distellar waste, emanating from soda ash and salt-making units, using the Solvay Process for production, has been standardised and granted a US patent," said Dr Pushpito Ghosh, director of CSMCRI, which is based at the Council of Scientific and Industrial Research (CSIR).

The new process has numerous process and environmental benefits for the processing of certain wastes, including the diversion of aqueous wastes from being dumped in the sea. It could also provide a new source of synthetic gypsum.

Germany: Scientists have observed tailor-made specialist micro-organisms directly 'feeding' on CO2-containing flue gases from lignite-fired power stations, in what is being described as a 'very promising' initial result of a research project run by RWE Power and Brain AG. The research may have interesting implications for the gypsum industry, which already uses desulphurised flue gas.

The joint project, which has been running since January 2010, aims to convert CO2 into biomass or directly into secondary raw materials with the help of micro-organisms bred to explore innovative CO2 conversion and synthesis pathways. The ultimate aims of the project are to produce industrially-usable products. These are likely to include insulation and construction materials.

"Our pioneering work in the search for biotechnological CO2 conversion solutions bears first fruit," said Dr Johannes Heithoff, head of research and development at RWE Power. "We continue to lead the efforts to protect the climate."

The work is being carried out at the Coal Innovation Centre located at the Niederaussem power plant, which hopes to produce scaleable solutions to reducing emissions from coal-fired power stations. If such solutions can be found, the gypsum industry may find that desulphurisation of flue-gas moves into competition with the production of insulation materials or other chemicals.

US: November 2011 saw more home starts in the US than any month since April 2010. The surge was reportedly led by an increase in multifamily units. The gypsum industry will be watching to see if the trend continues for December 2011, which might finally signify an upturn in demand for wallboard.

Starts increased by 9.3% to a 685,000 annual rate. Building permits, a sign for future construction, also climbed to a year-high. As well as multifamily homes, typified by apartments, demand for single-family-homes may also be increasing. A drop in house prices and low borrowing costs is thought to be the reason for the increase in demand.

"For months we've been flagging the strength in multifamily construction, but now we're starting to get signs that single-family is pulling itself off the canvas," said Brian Jones from Société Générale in New York.

North America: CertainTeed Gypsum, a Saint-Gobain subsidiary, has announced that UL Environment Inc. has completed its independent Environmental Claims Verification (ECV) process for products manufactured at five of its sites in North America. The company says that the move demonstrates a strong commitment to environmental responsibility and transparency.

UL Environment's ECV process has been completed for products manufactured at CertainTeed's Cody (Wyoming, US), Vancouver (British Columbia, Canada), Toronto (Ontario, Canada), Seattle (Washington, US), and Moundsville (West Virginia, US) manufacturing facilities. Specifically, UL Environment confirmed the pre- and post-consumer recycled content, origination of source materials (and adherence to ASTM D 3273 mould-resistance standards, if applicable) for 19 CertainTeed products. The validation process is currently underway for products manufactured at the company's remaining North American plants.

"CertainTeed has taken a unique approach by seeking validation for environmental product claims based on the specific plant in which they are manufactured," said Steve Wenc, president of UL Environment. "This demonstrates CertainTeed's commitment to providing detailed product information and an unprecedented level of transparency."

"Third party verification of environmental claims is a critical component of today's green building culture, as it provides independent evaluation and enhanced transparency," said John Donaldson, president of CertainTeed Gypsum. "CertainTeed has made significant strides in ensuring that building and design professionals have access to sustainable, high-performance gypsum products that help them to achieve their goals in the responsible development of our built environment."

Asia: Australian building material's group Boral has announced that it has completed its acquisition of Lafarge's interests in the two companies' former joint-venture Lafarge Boral Gypsum Asia. The business has been renamed Boral Gypsum Asia (BGA) and transition plans are in place for product branding in each country. BGA has performed to expectations since the acquisition was announced in August 2011.

The chief executive of Boral, Mark Selway, said, "We are delighted to be able to fully integrate BGA into our group. The continued growth of BGA is a strategic priority and we look forward to working with the management team and employees to develop and execute our plans for the future."
