US: CertainTeed Corp has reduced energy consumption by 15% and water usage by 24% over the past four years, according to a release. In addition, it has decreased the amount of waste going to landfills from its facilities by 33%.

"Our world-class team of employees at CertainTeed play a pivotal role in increasing the sustainability of our operations," said Chris Altmansberger, vice president of operations support and process sustainability at CertainTeed. "Through our collective efforts, we have established a strong culture of respect for the environment that will continue to help preserve and protect the communities in which we live and work."

During 2010 and 2011 approximately 6000 CertainTeed employees received various types of sustainability training, which has helped drive energy, water and waste reductions. Additionally, more than 30 plants have achieved ISO 14001 certification.

"Our increased emphasis on sustainability has helped us identify and implement critical initiatives that reduce water and energy use as well as divert waste from landfills," said Altmansberger. "We have learned that even simple modifications can have a big impact."

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.

Saudi Arabia: National Gypsum Company (NGCO) has announced that its net income fell by 44% in the financial year ending 31 December 2011 compared to 2010. The company reported an income of US$14m in 2010 compared to US$7.9m in 2011.

Gross profit in 2011 fell by 37%, to US$11m from US$17m in 2010. Income from operations declined by 42% in 2011 to US$8.2m from US$14m in 2010.

For the fourth quarter of 2011 net income fell by 48% compared to the same quarter in 2010, dropping from US$2.1m to US$1.1m. Net income fell by 3% in the fourth quarter of 2011 compared to the third quarter of 2011. Gross profit for the fourth quarter fell by 34% compared to 2010, falling from US$3.3m to US$2.2m. Income from operations for the fourth quarter fell by 38% compared to 2010, dropping from US$2.6m to US$1.6m

NGCO has attributed the reason for these decreases to net income, gross profit and income from operation to increased competition.

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.
