Commercial waste hauler Republic Services has added 14 compressed natural gas (CNG) vehicles to its fleet serving the Puget Sound area of Washington, bringing the total number of CNG trucks in that area to 109, the company has announced.

The CNG trucks replace older diesel-powered trucks operated by Republic. Each new CNG solid waste and recycling truck reduces carbon emissions by as much as 80 percent in comparison with older, diesel-powered trucks, according to the U.S. Environmental Protection Agency.

"We have a long-standing commitment to reducing carbon emissions locally, and our employees are proud to continue to make a difference with our latest CNG fleet deployment," said Mike Huycke, a Republic area president.

Republic installed a CNG fueling station in Bellevue in 2010 and recently expanded its CNG truck capacity at the station. 

Republic Services operates a fleet of more than 2,200 CNG vehicles and 38 natural gas fueling stations nationwide. Approximately 50 percent of all Republic vehicles purchased in 2014 run on CNG.
