Chicago-based Trillium CNG has struck an agreement with the Monterey Regional Waste Management District in California to build, own and operate a compressed natural gas (CNG) fueling station for the district’s refuse trucks.

A groundbreaking is set for April, and completion of the fueling facilities is slated for the end of July. The facilities would be built at the Monterey Regional Environmental Park and eventually use landfill gas that has been treated and compressed.

The new CNG station would provide time-fill posts to handle the waste district’s 50 CNG refuse trucks currently in operation as well as a fast-fill dispenser that can be made available to other local city/county fleets, a spokesperson said.

The facilities would be expandable to accommodate up to 100 CNG vehicles in the district’s fleet when it is fully converted.

By mid-2016, the waste district plans to extrude methane gas produced at the nearby Monterey Peninsula Landfill and convert the recovered gas to CNG. Trucks would start and end their day at the site, according to Tim Flanagan, the waste district’s assistant general manager.

“It’s really sort of a perfect closed loop resulting in negative carbon impact,” Flanagan said.

Trillium President Mary Boettcher called the Monterey undertaking “an innovative and environmentally advanced project.”
