Gypsum industry news

Vietnam: David Victor Thomas, general director of Knauf Vietnam, has announced that Thuan Hung Building Materials Co, based in Tien Giang Province, will be the first distributor of Knauf's gypsum wallboard in the region.

Knauf has imported its products to Vietnam since late 2013. The company was licensed to build a wallboard factory in the city of Haiphong in 2013 and its products will be launched in 2015.

USA: A new study highlights the top reasons that crop growers apply gypsum to cropland. The research cites increased yields, valuable sulphur fertility and soil quality improvements as key benefits of gypsum use, contributing to positive financial returns. The study involved an extensive review of published scientific literature, in-depth interviews with several long-time gypsum users and a survey of US farmers.

"On average, gypsum users received US$1.68 in return for every US$1 invested in gypsum. In addition, gypsum significantly improved the productivity of their soil," said Marvin Batte, professor emeritus of The Ohio State University. "Many gypsum users experienced even higher returns. Plus, there were significant environmental benefits as well."

"Returns were highest for alfalfa where users experienced dramatic increases in yield," said Batte. "In alfalfa, returns per dollar of gypsum cost were often 5:1 or higher. In corn, returns were 2:1 or higher. Alfalfa is a crop with a high sulphur requirement and gypsum supplies sulphur in the sulphate form, which is readily available to plants, unlike elemental sulphur that must be converted to a usable form," said Ron Chamberlain, lead agronomist for Gypsoil. The value of sulphur in gypsum is more than US$16/acre (24281m²) for a 6t alfalfa yield and more than US$5/acre for a 200-bushel corn crop. Producers also found that gypsum improved the effectiveness and efficiency of other plant nutrients, including nitrogen, phosphorus and potassium.

While increased yield and improved fertility were among the easiest benefits to measure, improved soil quality was viewed by many, especially long-time gypsum users, as the most important benefit. The most valuable soil improvement benefits included improved plant rooting, improved seedling emergence, increased soil water retention, reduced runoff and improved absorption of nutrients. Enhanced soil biological activity was also noted.

Germany: Saint-Gobain has been certified for the seventh time in a row as a top employer in Germany for its outstanding employee offerings, by the Netherlands-based Top Employers Institute, which recognises leading employers around the world.

The participating companies were SG Glass, SG Sekurit, SG Performance Plastics Pampus, SG Weber, SG Isover and SG Informations Systems. The best results were achieved in the categories 'secondary benefits' and 'culture management,' in which Saint-Gobain was among the top 10 of the 125 certified companies. Furthermore, the companies named above achieved the Top Employers Europe 2014 certification, as they had also been certified in various countries in Europe.

Reinhard Runte, HR director of Saint-Gobain in Germany and Austria and HR managing director for SG Glass Deutschland, accepted the award in the name of all participating companies on 6 March 2014 in Dusseldorf. "I am very happy about receiving this award again and also a little proud as it shows that, despite the increasing standards set by the Institute, we could improve our performance."
