The City of Spokane unveiled its newest compressed natural gas garbage trucks Monday morning.
Overall, the city will replace 90 trucks over the next seven years, cutting its green house gas emission by 20 percent. While CNG trucks cost around $30,000 more than standard diesel, the city says that cost is recouped in three years, through fuel and maintenance savings.
The city estimates the new CNG vehicles, which cost $360,000 per unit, will save the city around $8,000 a year per truck compared to the older diesel models.
The new CNG trucks will last about 10 years and the gas tanks on the new vehicles have to be certified every five years.
