Waste Management Liquefied Natural Gas Trucks

The Fleet Test and Evaluation team worked with Waste Management to study the engine design of five liquefied natural gas (LNG) trucks manufactured by Mack and equipped with E7G engines. The evaluation, which was conducted between November 1998 and May 2000, focused on the cost, maintenance, operational, and emissions characteristics of LNG in heavy-duty trucking applications at the company's Washington, Pennsylvania, facility.

Headquartered in Houston, Texas, Waste Management boasts more than 350 collection operations and 300-plus transfer stations. It also has several waste-to-energy plants, recycling facilities, and landfill gas projects.

The results of this study are featured in Waste Management's LNG Truck Fleet Alternative Fuel Truck Evaluation Project: Final Results.
