French company Air Liquide said it will build and operate its first US landfill biogas purification plant in Walnut, Mississippi.
The company has more than 50 biogas sites worldwide but none in the US to date.
The Air Liquide plant, which will convert methane emitted by decaying waste to renewable energy, will be located on a site owned by the Northeast Mississippi Solid Waste Management Authority and operated by solid waste company Waste Connections. The site receives about 350,000 tons of waste per year.
The company says its biogas purification technology, which involves its patented polymeric membranes, generates high-quality biomethane with a methane content between 95 percent and 99 percent.
Air Liquide expects to break ground on the project in the first quarter of 2017. The plant will initially 1,300 mmBTU of biogas per day, with the potential to expand capacity.
The company will also build a 4-mile pipeline that will feed the biogas into a natural gas pipeline in the area. Construction of this pipeline enable the town of Walnut to expand its utility services, Air Liquide says.
The announcement comes as the Obama administration’s methane emissions standards have spurred investment in new landfill-gas-to-energy plants. Just last month, Ameresco completed a 16-megawatt landfill-gas-to-energy project in Illinois.
In addition, the EPA’s Landfill Methane Outreach Program provides landfill owners and operators a suite of tools and technical resources to facilitate development of landfill gas energy projects.
These types of projects will likely increase as states such as California set their own strict methane emissions rules.
