UK/Spain: Fermacell has officially opened a new 12MM2/yr gypsum fibreboard plant near Santander in Spain. The Euro30m plant is intended to target growing market demand and increase the company's supply to its European distribution network.

"Increasing market demand and additional sales potential are the main reasons for expanding the production of gypsum fibreboards and the opening of the new factory. Our international sales offices are faced with extensive utilisation of existing factories and the new Spanish plant will improve supply to the UK and other large construction markets across Europe," said Fermacell UK general manager, Gary Carter.

Kazakhstan: Zhambylgypsum plans to start a gypsum production line in the Zhambyl region by the end of 2015, according to the ADM Kazakhstan Capital Restructuring Fund.

"This will be the first such facility in the post-Soviet era. The plant will produce 600t/day of gypsum and 15m3/hr of fluff perlite, 7t/hr of calcite flour and 30t/hr of dry mortar," said Zhambylgypsum head Kaynarbek Kusayynov.

ADM Kazakhstan Capital Restructuring Fund, part of Kazyna Capital Management, provided funds for the project, in particular for the expansion of production capacities and purchase of gypsum calcination equipment. ADM KCRF was set up in 2010 with capital standing at US$100m. Its main investors are the European Bank for Reconstruction and Development and JSC Kazyna Capital Management.

US: Carbon monoxide (CO) from external sources can easily penetrate gypsum wallboard according to a study published in the Journal of the American Medical Association by Neil B Hampson, James R Holm and Todd G Courtney of the Virginia Mason Centre for Hyperbaric Medicine. The study is believed to be the first to examine the ability of CO to diffuse through gypsum wallboard.

In the study, a plexiglas chamber divided by various configurations of gypsum wallboard was used to determine whether CO diffuses across wallboard. Wallboard of various thicknesses were used. CO test gas was infused into the chamber and then CO concentrations were measured once per minute in each chamber for 24 hours. The authors sought to determine how rapidly a concentration of CO toxic to humans would be reached in the non-infused chamber and whether diffusion would then continue. The researchers found that CO diffused across single-layer gypsum wallboard of two thicknesses, double-layer wallboard and painted double-layer wallboard.

"Gypsum's permeability to CO is due to its porosity. The ability of CO to diffuse across gypsum wallboard may explain at least some instances of CO poisoning in contiguous residences. Exempting residences without internal CO sources from the legislation mandating CO alarms may put people in multifamily dwellings at risk for unintentional CO poisoning," said the study. Carbon monoxide poisoning causes about 500 accidental deaths annually in the US.
