‘Nationwide, 36% of Our Natural Gas Fleet Runs on Biomethane’
Waste Management now operates more than 5,000 natural gas vehicles out of its overall fleet of more than 32,000. “One of our primary strategies for reducing emissions,” the company says in its just-released 2016 Sustainability Report, “is to transition our fleet of 18,500 collection vehicles from diesel to cleaner-burning natural gas.”
“Today, we have more than 5,000 natural gas collection trucks on the road, which makes us the largest private vocational heavy duty fleet user of natural gas in the nation,” the company says. Efforts to slash greenhouse gas emissions began in earnest in 2007 (a goal of 15% was reached in 2011), although Waste Management has been operating NGVs since the late 1990s.
Today more than 90% of Waste Management’s new truck purchases are for compressed natural gas-fueled trucks. “For every diesel truck replaced with natural gas, we reduce our use of diesel fuel by an average of 8,000 gallons annually,” the company says.
Greenhouse Gas Reductions
CNG further makes for a GHG emissions reduction of 22 metric tons per truck per year, equal to a 21% GHG emissions reduction.
The company is emphasizing RNG/renewable natural gas too, noting production of liquefied natural gas at a landfill east of San Francisco and RNG for vehicles at landfill in Illinois and Ohio.
The Altamont Landfill in Livermore, Calif. dates from in 2005, Waste Management notes. The company produces as much as 13,000 gallons of renewable LNG daily there, fuel used by several California truck fleets (F&F, April 18, 2013).
RNG in Illinois and Ohio
The Altamont LNG “represents a 90% reduction in GHGs as compared with diesel,” states the latest report. “Since its creation, the plant has produced more than 16 million gallons of LNG for use in trucks.”
“In total, nearly one third of our fleet uses biogas and 100% of our fleet in California runs on renewable natural gas,” the report states. “Nationwide, 36% of our natural gas fleet runs on biomethane.”
Waste Management operates on-site RNG production equipment at its Milam Landfill in Illinois and the American Landfill in Ohio. Milam can support 470 trucks at current production levels and American can support as many as 400 trucks.
