Continuous monitoring of landfill gas

Guidance on monitoring landfill gas surface emissions

Landfill Gas Monitoring Network - Development of Wireless Sensor Network Platforms

A wireless sensor network has been developed for the application of landfill gas monitoring, specifically sensing methane, carbon dioxide and extraction pressure. This collaborative work with the Irish Environmental Protection Agency has been motivated by the need to reduce greenhouse gas emissions as well as aiming to improve landfill gas management and utilisation. This paper describes the pr...

Remote Real-Time Monitoring of Subsurface Landfill Gas Migration

The cost of monitoring greenhouse gas emissions from landfill sites is of major concern for regulatory authorities. The current monitoring procedure is recognised as labour intensive, requiring agency inspectors to physically travel to perimeter borehole wells in rough terrain and manually measure gas concentration levels with expensive hand-held instrumentation. In this article we present a co...

Beneficial Use of Landfill Gas

1 page only) With regulatory and environmental pressure toward control of landfill gas (LFG) management of collected LFG has become a significant issue. At a minimum, collected LFG must be flared for control of methane and nonmethane organic compounds. Beneficial reuse of LFG as an alternative to combustion has tremendous potential at most landfills. Issues facing reuse of LFG include gas compo...

EMERGING TECHNOLOGIES Continuous Intravascular Blood Gas Monitoring

N AVERAGE adult at rest consumes approximately A 100 million trillion molecules of oxygen per second; with virtually no capacity for oxygen storage, cessation of oxygen delivery quickly results in irreversible cellular damage. The human cardiopulmonary system functions remarkably well in healthy individuals, maintaining the mitochondrial oxygen tension (greater than 1 mmHg) required for aerobic...
