Proposed EPA Renewable Fuel Standard for 2017 & Biomass-Based Diesel Volume for 2018

Renewable Fuel Standard

Summary of the Proposed EPA Renewable Fuel Standard The US Environmental Protection Agency (EPA) has proposed increases in the volume requirements of all kinds of biofuels in accordance with the Renewable Fuel Standard (RFS) program. These increased volumes will boost biofuel production and make ambitious expansion and growth possible in this sector. The volume requirements […]

Accurate MSW Disposal Estimates Needed to Reduce Landfill Gas Emissions

Reducing landfill gas emissions

A recent study conducted by a research team from Yale and the University of Florida has revealed that the amount of solid waste Americans are disposing in landfill gas emissions is more than double initial estimates. The study concludes that with more accurate waste disposal figures at hand, we can now set about reducing greenhouse […]

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 […]

Controlling Landfill Emissions Guidelines (Part 2)

Controlling landfill emissions

Summary of Proposed Updates to the Landfill Emission Guidelines for Existing Municipal Solid Waste Landfills Amendments to Landfill Emissions Thresholds The EPA is proposing to amend the emissions threshold that would require a landfill to install a landfill gas (LFG) collection and control system. For both active and new landfills, this would effectively reduce the […]

Controlling Landfill Gas Emissions (Part 1)

Landfill gas emissions fromMSW llandfill site

Proposed Updates to the Emission Guidelines for Existing Municipal Solid Waste Landfills In August 2015, the EPA updated their Emission Guidelines for existing municipal solid waste landfills in an effort to reduce greenhouse gas emissions (notably methane) released in landfill gas. In addition, it also proposed amendments for reducing GHG emissions from modified landfills as […]
