Clarksville's biodiesel-powered buses
The acquisition was funded by a federal grant, and will allow Clarksville Gas and Water to convert used cooking oil into biofuel. The city hopes that the biodiesel produced will eventually power the city’s buses. This will cost significantly less, as ordinary diesel is priced at almost $2.80 per gallon (€2).
‘We think that we’re procuring this product for about $0.92 to $0.95 a gallon. That’s, of course, very much lower than diesel,’ said Tommy Williams, a supervisor at the wastewater plant in Clarksville.
The used oil comes from donations from around 12 restaurants. Williams explains that this oil would normally end up in the sewer lines and is being converted into a product that is much greener for the environment, compared to diesel.
Since it was installed last December, the unit has produced a few hundred gallons of biodiesel. Eventually, the city plans to expand the programme for use in buses and other vehicles, to take advantage of the fuel savings.
