The Local Municipality of Madibeng this week denied claims that a contractor was appointed on a contract of almost R3 million at the landfill site in De Kroon without a tender being issued. Gundle Geosynthetics (Gauteng, South Africa) was appointed directly, the council has said, in order to guarantee expert work at the environmentally sensitive site. While local contractors may be upset about not having the work, they must understand that most geosynthetic types require careful handling and experience. They must not be confused with earthworks.

This interest in rubber-based liners for SAG milling flies in the face of the previous belief that a SAG mill, using large-diameter grinding media, was just too tough an environment for rubber. But synthetic and natural rubbers are moving from secondary liner status to primary liners in grinding applications at mines. A Canadian company claims to have supplied liners to more than 300 mills around the world. Learn more here.;

The battle against global warming may turn out to be a boon for a California industry long targeted by environmentalists -- dairies. Green engineering is taking off in agriculture with the help of technologies such as methane-harvesting digesters with geosynthetic covers. David Albers, president of the 2,800-cow Vintage Dairy in western Fresno County, is also part of BioEnergy Solutions, a company utilizing geomembrane covers for power-converting systems. They are hoping to raise money to create a network of 40 dairies plugged into the grid. Learn more here.;

Geomembrane barriers are essential to many applications and industries, but they do not perform as designed unless their highly-engineered panels are properly welded. Welding requires care and precision, and the longer it takes to secure a barrier, the more expensive the installation becomes. Demtech's latest wedge welder, the Pro-Wedge 3XL, is the most advanced wedge welder on the market, combining exceptional safety and accuracy with what is by far the fastest welding speed available. With its longer wedge and greater heating power, it is 3 times faster, even for the most challenging geomembrane installations. Read more.
