Louisiana waste disposal district recognized for biogas project
The U.S. EPA 2012 Landfill Methane Outreach Program has awarded the St. Landry (La.) Solid Waste Disposal District the Project of the Year Award for using compressed landfill gas to power 13 vehicles in the St. Landry Parish sheriff department’s fleet.
To convert the landfill gas into transportation-grade fuel, the biogas is fed through a conditioning system manufactured by BioCNG LLC. The system utilizes sulfa and carbon treatments to remove hydrogen sulfide, siloxane and other volatile organic compounds. The gas is then sent through a series of filters and membranes to remove carbon and particulates before being chilled and compressed for use in compressed natural gas equipped vehicles.
