Compressed Natural Gas (CNG) Waste Equipment Works in the Waste Industry

Proud of its progressive, green-thinking culture, Seattle ranks among the best U.S. cities for the size of its carbon footprint. Forbes magazine calls Seattle one of the country’s cleanest, most environmentally commit­ted cities.

Based in Seattle, CleanScapes is a municipal solid waste con-tractor that demonstrates its commitment to environmental protection in a big way.

Since April 2009, each morning, 40 brightly-colored CleanScapes waste equipment vehicles fan out across the central and north­eastern sections of the city to serve 64,000 residential and commercial customers. This CleanScapes fleet is powered by clean-burning compressed natural gas (CNG).

To support its new CNG fleet, CleanScapes turned to Clean Energy to design, build and maintain a new time-fill station equipped with 40 state-of-the-art CNG fuel dispensers, one for each truck. CleanScapes also contracts with Clean Energy for the fleet’s CNG fuel supply.


Achieving a clean, green operating profile was an important goal in the com­pany’s choice of a CNG fleet. CleanScapes President Chris Martin said, “Seattle is a national leader in greenhouse gas emissions reduction. After careful analysis we determined that a CNG fleet would bring significant environ­mental benefits to the communities we serve in the city.”

Compared to diesel fuel operating in other waste equipment vehicles, natural gas fuel provides signifi­cant reductions in health-harming pollutants and green­house gas emissions. In addition to protecting envi­ronmental quality, CNG solid waste trucks are more economi­cal to fuel and operate, quieter running than diesel trucks, and easier to maintain, Martin explained.

“The CNG trucks provide a very welcome reduction of emissions and noise levels in some of the most populated areas of Seattle,” he added.

Nicknamed The Emerald City, Seattle is famous for its air qual­ity and pristine natural setting. The decision by CleanScapes to deploy clean-burning CNG waste equipment vehicles will help keep it that way.
