In addition to (MSW), commercial and industrial offensive smells and smouldering providing high-efficiency, reliable gas engines we combine (C&I) wastes and other fires, the gas must be continuously biodegradable waste streams. extracted under controlled conditions. this with the expertise and resources to deliver unbeatable Depending upon the landfill design Perforated tubes are drilled into the product support. and its management, as well as landfill body and interconnected by waste composition, compaction, a pipework system. Using a blower, Whether your requirement is for the supply of a single gas moisture and several other factors, the gas is sucked from the landfill. engine generator or a complete turnkey power generation thousands of landfills are available A well-designed gas collection facility, we can meet that need. Our ability to add value by worldwide to collect and utilise this system will flexibly capture the gas valuable source from various spots and handful high offering an end-to-end service, from initial proposal to for power generation. If landfill gas is temperatures, leachate, condensates reliable long-term maintenance, has led to us becoming a allowed to escape to atmosphere, and air content – thus ensuring a multi-national company with operations in ten countries methane contained within it is a cost-efficient collection as well as across the globe. Our company prides itself on integrity, powerful greenhouse gas, 21 times stable gas quality. Several delivering only the highest quality products whilst providing more so than carbon dioxide. companies specialise in a reliable accountable localised service.
