Landfill Gas


Landfill Gas

Landfill gas is created during the anaerobic decomposition of organic substances in municipal solid waste (MSW), commercial and industrial (C&I) wastes and other biodegradable waste streams. Depending upon the landfill design and its management, as well as waste composition, compaction, moisture and several other factors, thousands of landfills are available worldwide to collect and utilise this valuable renewable energy source for power generation. If landfill gas is allowed to escape to atmosphere, methane contained within it is a powerful greenhouse gas, 21times more so than carbon dioxide. Therefore, its prevention of escape to atmosphere and its utilisation as a renewable fuel source is a win-win situation.

Benefits of Landfill Gas Power

— Production of renewable power
— Avoidance of greenhouse gas emissions
— Cost effective, proven technology

Landfill Gas Collection

For a landfill restoration that prevents greenhouse gas from migrating into the atmosphere while avoiding offensive smells and smouldering fires, the gas must be continuously extracted under controlled conditions. Perforated tubes are drilled into the landfill body and interconnected by a pipework system. Using a blower, the gas is sucked from the landfill.

A well-designed gas collection system will flexibly capture the gas from various spots and handle high temperatures, leachate, condensates and air content – thus ensuring a cost-efficient collection as well as stable gas quality. Several engineering companies specialise in this field and offer their services on a worldwide basis.
