Geomembrane Technologies custom-designs, fabricates and installs gas collection covers to capture biogas from the anaerobic digestion process. The biogas can be converted to generate process heat or electricity, helping offset energy costs. They fit tanks and lagoons of all sizes. These durable, gastight covers collect biogas while containing foul odors from wastewater treatment. The covers are also safe to walk on, and the insulated option provides additional buoyancy and helps maintain consistent temperatures. The cover also helps minimize greenhouse gases. They are constructed with high-quality, specialized material and last upward of 20 years. 855-484-4630; www.gticovers.com
