A 40-acre (160,000 m 2) landfill gas collection system with a flare designed for a 600 ft 3 /min extraction rate is estimated to cost $991,000 (approximately $24,000 per acre) with annual operation and maintenance costs of $166,000 per year at $2,250 per well, $4,500 per flare and $44,500 per year to operate the blower (2008). LMOP provides a ...
A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste.
Landfill gas monitoring is the process by which gases that are collected or released from landfills are electronically monitored. Landfill gas may be measured as it escapes the landfill ("Surface Monitoring") or may be measured as it is collected and redirected to a power plant or flare ("Collection System Monitoring").
Leachate Collection and Removal Systems - sit on top of the composite liner and removes leachate from the landfill for treatment and disposal. [ 5 ] Operating Practices - including the compacting and covering of waste frequently with several inches of soil to help reduce odor; control litter , insects and rodents ; and protect public health .
LoCI's system is designed to increase methane gas extraction from landfills. The software and hardware provide remote monitoring and control, versus historical practices, which require twice-monthly on-site monitoring and manual adjustments to extract the methane.
All modern landfill sites use a combination of impermeable liners several metres thick, geologically stable sites and collection systems to contain and capture this leachate. It can then be treated and evaporated. Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation.
The collection pipe network of a leachate collection system drains, collects, and transports leachate through the drainage layer to a collection sump where it is removed for treatment or disposal. The pipes also serve as drains within the drainage layer to minimize the mounding of leachate in the layer.
The gas collection system extracts gas from deep inside the landfill and burns it. In 2002, EPA installed micro-turbines which convert landfill gases into electricity for operating site systems. Environmentally friendly, the micro-turbines send their emissions towards the gas treatment system, destroying all contaminants.
