Now serving Seattle neighborhoods and businesses, the cleanest fleet in the City’s history includes 101 Waste Management vehicles powered by either renewable natural gas – gas from garbage – or by electricity. The new Waste Management fleet includes:
- Ninety-one collection trucks equipped with the new Cummins Westport ISL G Near Zero engine and powered by renewable natural gas (RNG). The heavy-duty engine is the cleanest ever certified by the California Air Resources Board and the Environmental Protection Agency. RNG is better for the environment because it is not a fossil fuel and it generates dramatically lower emissions – 70% lower than traditional diesel and 65% lower than compressed natural gas.
- RNG is a renewable fuel harvested from landfills – an innovative and green transportation fuel to replace fossil fuels. RNG begins as a biogas when garbage decays inside landfills. Waste Management uses underground vacuum systems to collect the biogas so it can be cleaned and loaded into pipeline infrastructure, similar to how electricity is loaded to the power grid for transmission across the country.
- Eight Nissan Leaf electric support vehicles for use by WM route managers and bilingual recycling educators assigned to help Seattle residents and businesses reduce waste.
- Two battery-electric Class 6 box trucks, the WM Think Green Seattle Street Crew, which will be on the job soon to keep downtown alleys clean and provide special collection services.
The new fleet and enhanced services are the result of a new contract between Seattle Public Utilities and Waste Management. WM provides service to residents and businesses in approximately 60 percent of the city. For more about residential service in Seattle, visit seattle.gov/util.
