ST. LOUIS, MO (KTVI) – Waste Management is replacing much of its trash-hauling fleet with trucks that burn cleaner fuel. The new trucks run on CNG, compressed natural gas. The conversion can be costly: $2 million for the fueling station and $330,000 for the trucks. But, the company will save more than a dollar a gallon every time they fill up.
Waste Management is just the latest of several St. Louis area companies making the conversion from fuel to compressed natural gas.
