Review of Landfill Surface Emissions Monitoring - WR0604

Description
Methane has a high global warming potential and is the principal component of the gas generated from the biodegradation of organic wastes in landfill. The methane in landfill gas releases are estimated to make a significant, and avoidable, contribution to the UK’s reported emissions of Greenhouse gases under the Kyoto Protocol. Landfill operators are required under their permit to quantify emissions of methane through the surface of the landfill cap.

The current Guidance issued by the Environment Agency (based on research by the Department of the Environment in 1995) recommends the use of flux boxes to quantify the emissions from capped areas. Since the 1990s, new techniques have been developed, but they have not been standardised or independently evaluated for their suitability or practicality on UK landfill sites. This project aimed to review the methods for estimating the pattern of fluxes of gases across the surface of a landfill and their variations with time.
Objective
The general aim of the project is:

- To review the methods for estimating the pattern of fluxes of gases across the surface of a landfill and their variations with time, i.e. spatial and temporal variation in emissions.

The review considers techniques which have the potential for monitoring landfill emissions; to look at the various regulatory needs, and to assess each method against these regulatory requirements for their suitability, ease of use, potential problems and costs. The review has identified the most suitable techniques which have potential for use in the UK.
