High quality gas sensor solutions for landfill - Waste and Recycling - Landfill
State-of-the-art systems enabling easy monitoring of CO2 and CH4 gases. A landfill site is a site for the disposal of waste materials by burial. Historically, landfills have been the most common method of organised waste disposal and remain so in many places around the world. Some landfills are also used for waste management purposes, such as the temporary storage, consolidation, and transfer, or processing of waste materials. Landfill gas is created by the action of microorganisms within a landfill. This includes the evaporation of volatile organic compounds, chemical reactions between waste components and microbial action. The emitted gas consists of 40-60% methane, and the rest mostly carbon dioxide. Trace amounts of other volatile organic compounds (mainly simple hydrocarbons) also compromise the remaining 1%.
Why is Landfill Gas Sensing necessary?
Legislation requires that landfill gas is safely removed to avoid a physical explosion due to the build-up of pressure beneath the cap. Safe disposal usually entails burning such as flare stacks, internal combustion engines or by processing to produce Methane gas fuel. For large sites with access to power distribution, infrastructure internal combustion engines are used to generate electricity which is fed into the local electricity grid.
Instead of escaping into the air, landfill gas can be captured, converted, and used as a renewable energy resource. Using landfill gas helps to reduce odours and other hazards associated with its emissions, and prevents methane from migrating into the atmosphere and contributing to local smog and global climate change.
All of the above safe disposal processes require the measurement of the Methane content (and in many cases the CO2 concentration). Edinburgh Sensors provide gas sensors for both Methane and CO2 that can be integrated into landfill gas processing systems enabling easy monitoring of these gases.
