St. Landry Parish Landfill
St. Landry Parish, LA


St. Landry Parish Solid Waste District implemented a BioCNG system that can produce 250 gallons of gasoline equivalent (GGE) of CNG per day at less than half the cost of gasoline. The biogas-based fuel is used to power St Landry Parish Sheriff’s Department cars, light duty trucks and a light duty van, and the solid waste district’s utility trucks. As part of the project, the Sheriff’s Department committed to converting twelve of its vehicles to bi-fuel capability, and added a passenger van fueled solely on CNG.

The fuel is produced from 50 scfm of biogas containing 55 to 58 percent methane. The system was expanded in 2015 to include development of a primary/satellite fueling system concept.  The primary site included an additional BioCNG system capable of providing and additional 640 GGE of BioCNG per day for on-site fueling.  Also located at the primary site is a natural gas transport trailer that transports BioCNG to an off-site (satellite) fueling station.  The additional fuel is sold to a large refuse hauling company for use in its fleet of 10 CNG refuse trucks.

In January 2013, the St. Landry Solid Waste Disposal District received the federal Environmental Protection Agency’s 2012 LMOP Project of the Year Award, the second such honor given to the innovative BioCNG system.
