Some Ozark Buses Help Keep Air Clean

By  | 

One wiregrass city is hoping to reduce air pollution, by driving buses?

Ozark city school's bus system is filling up in a new way.

Six of the 38 buses are now using bio-diesel to test how the environment-friendly fuel will run.

The school system has put the fuel in busses ranging from its oldest 1996 model to its newest 2007 model.

The fuel is designed to not only keep the engine clean... But reduce the sludge from older engines that is use regular diesel.

"It’s a win/win for everybody. The community benefits, and it works to clean the engine in some of the older buses and it's a lower sulfur fuel... We felt like it would provide us the opportunity to not only save some money, but also burn a cleaner fuel." says Dr. Dan Payant, Ozark city schools superintendent.

The b-20 on the bio-diesel fuel tank means it's 20-percent bio-diesel.

The other 80-percent is petroleum.

That 20-percent my not sound like a lot, but the US department of energy and the US department of agriculture says it cuts carbon-dioxide emissions by 78-percent.

"I think it's important to teach our children that we need to make wise choices regarding our environment and our energy needs. If we're not doing that, then we certainly are not teaching our kids the importance of that." says Payant.

School leaders say if using bio-diesel is as much of a success as they hope, they will use it on all of the buses.

In 2000 bio-diesel became the only alternative fuel in the county to have successfully completed the EPA required tier one and tier two health effect testing under the clean air act.
