WM rolls out green fleet in Seattle

Waste Management will be using more than 100 trucks fueled by RNG generated from Seattle waste.

SEATTLE – The city of Seattle is rolling out its new green fleet of recycling, compost and garbage trucks. The fleet includes 101 Waste Management vehicles powered by either renewable natural gas – gas from garbage – or by electricity.

Ninety-one collection trucks are 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 generates dramatically lower emissions – 70 percent lower than traditional diesel and 65 percent lower than compressed natural gas.

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 are used 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, will be on the job 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.

The company uses waste that cannot be recycled to generate renewable energy for Seattle City Light, providing electricity to power 12,500 homes in Seattle.
