French industrial gases company Air Liquide SA (EPA:AI) last week said it will build its first landfill gas to renewable natural gas purification plant in the US.
The facility will be located at the Northeast Mississippi Landfill in the city of Walnut, Mississippi and will produce enough renewable energy to heat an estimated 4,500 homes per year. It will employ Air Liquide's gas separation membrane technology to purify the methane emitted by waste decay and make it suitable for use.
The company will be responsible for the design, construction and operation of the plant. It will also build a 4-mile (6.4 km) pipeline that will feed the biogas into a natural gas pipeline in the area.
Construction on the plant is expected to start in the first quarter of 2017. Initial capacity is planned to be 1,300 mmBTU a day, with plans for expansion.
The landfill site is owned by the Northeast Mississippi Solid Waste Management Authority and is operated by solid waste company Waste Connections Inc.
