The trucks that pick up much of Middle Tennessee's trash will start running cleaner.
Waste Management announced this week plans to add 45 collection vehicles that are powered with compressed natural gas by 2017. The company already operates 25 such trucks in the area.
Replacing a single diesel truck with one powered by natural gas saves an average of 8,000 gallons of diesel fuel a year, and cuts particulate matter emissions by 86 percent, the company said.
"For every truck we put on the road, that's the equivalent of removing about five passenger vehicles from the road," said Robert Cheney, director of business development. "So when we're done with 90 trucks, we're going to have 400 to 450 passengers that have been removed from the road."
With the expanded use of natural gas, Waste Management is also opening a fueling station on Antioch Pike, open around the clock to individuals and businesses driving CNG vehicles.
