EPA Takes Steps to Reduce Methane Emissions from Landfills

Capturing methane emissions from landfills key to reducing climate warming

Early this year, the US Environmental Protection Agency implemented a rule introduced in 2016 by the Obama administration that lowers the threshold at which landfills are required to install methane collection systems. The implementation of the rule will require an additional 93 landfills across the country to install landfill gas collection systems and will help to curb […]

Methane from Manure: Could Farms be Power Plants of the Future

Methane from manure biogas projects reduce greenhouse gas emissions

Livestock farms could provide an abundant supply of renewable energy through methane from manure projects. Farm manure, already widely used in biogas projects, could provide a  readily available and renewable source of energy that would reduce greenhouse gas (GHG) emissions responsible for global warming and climate change. When manure and other organic matter breaks down, […]

Anaerobic Digestion of Wastewater Sludge: A Primer

Anaerobic digesters at Black River wastewater treatment plant

Anaerobic digestion is the most commonly used method of wastewater sludge treatment, where the primary aim is to break down the sludge in order to minimize the volume that is left for disposal. During this process the organic matter is decomposed by anaerobic bacteria in an oxygen-free environment, producing carbon dioxide and methane gases and […]

EPA Introduces Landfill Methane Outreach Program

Landfill Methane Outreach Program hopes to expand landfill mthane capture initiatives across the country.

    The EPA has launched the Landfill Methane Outreach Program (LMOP), a voluntary program that encourages waste managers and other stakeholders in the landfill industry to reduce methane emissions from landfill sites. Rather than being released into the atmosphere as a potent greenhouse gas, Landfill Methane Outreach Program promotes the recovery of landfill gas, […]

Size, Capacity of Landfill Sumps & Leachate Pumps

Leachate pumps and sumps

In a previous series of articles we covered various aspects of landfill design, including landfill layout, configuration and slope design; landfill liner systems; and leachate collection systems. In this article we are going to focus on the leachate drainage system and the landfill sumps and leachate pumps that are used within the collection system. Leachate […]
