Upgrading landfill gas (LFG) offers several significant benefits – both environmental and financial. The primary component of landfill gas is methane (CH4), which is a potent greenhouse gas with a much higher global warming potential than carbon dioxide (CO2) over a shorter timeframe. By upgrading landfill gas and converting methane into biomethane, emissions of methane are significantly reduced – helping to mitigate climate change while also aligning with emissions reduction goals.

In addition, upgraded landfill gas, or biomethane, is a renewable energy source. It can replace fossil fuels like natural gas, diesel, or gasoline in various applications including heating, electricity generation, and transportation. Using biomethane reduces the reliance on non-renewable resources and decreases carbon emissions associated with traditional energy sources. It also has value in energy markets and can be sold as a renewable natural gas (RNG) to utilities, industries, and even used as vehicle fuel. This creates revenue streams for landfill operators, making waste management more economically sustainable.

BIOFerm Solutions for Landfills

Dry Digester

Divert an organic waste stream from your facility to an anaerobic digester to increase biogas yields.

Gas Upgrading

Utilize BIOFerm’s 1-Stage or 2-Stage Pressure Swing Adsorption (PSA) system to efficiently process your high nitrogen landfill gas (LFG).

Activated Carbon

Our specialized activated carbons were developed for the biogas industry to remove hydrogen sulfide (H2S) & volatile organic compounds (VOC).

Featured project – Gas Upgrading

BIOFerm installed the first 2-Stage Pressure Swing Adsorption (PSA) gas upgrading plant in North America for the Dane County Landfill to generate renewable natural gas (RNG) for clean transportation fuel.

Previously, the Dane County Landfill generated electricity with the gas collected from the breakdown of garbage and organic waste. However, this facility enables the county to convert its landfill gas into vehicle fuel, thereby eliminating thousands of tons of carbon emissions.
