A MidMichigan community takes another step in becoming a zero-waste city.

Flint unveiled its first biogas vehicle at Kettering University.

It's intended to educate, enlighten, and employ.

Green technology now powers a Chevrolet Silverado 2500 heavy duty pickup truck. More specifically and scientifically, without getting too detailed, it's brown technology.

Researchers capture the energy from the toilet to the fuel tank.

Kettering University fuel cell lab technician Jeremy Gnida says, "It's nice to get away from petroleum products and explore our options with different fuels."

The truck has a second fuel tank next to the gasoline fuel tank that Kettering University students installed. It feeds a large barrel in the truck bed that holds the biomethane. The truck can run on either gas or biomethane.

The students say it's not that difficult to install.

Nolan McCann, a Kettering University research assistant, says "The only major changes, you have to add additional injectors for the fuel for the compressed natural gas, so this engine has both injectors for gasoline and compressed natural gas."

For safety reasons, only certified installers can legally do install it, and Kettering would like to eventually convert all of Flint's city vehicles to biomethane.

Tom Guise, CEO of Swedish Biogas, says "We're in conversations with the MTA (Mass Transportation Authority), because the MTA has plans to switch over to natural gas, and so we're hoping to use the biogas to supplement the natural gas."

City officials say it's not just about energy, but employment.

Flint Mayor Dayne Walling says, "If you want to have the jobs, you've got to have the innovation and the good ideas. That's what's always fueled the auto industry from its early days. That's what made Flint such a hot spot. Now we've got to do it again."

Researchers say the biomethane costs around $1.80 a gallon and gets slightly fewer miles per gallon than regular gasoline.

As of today, some of the lowest regular gas prices were around $2.50 a gallon.

The biomethane truck shows off this weekend for Flint's Back to the Bricks celebration and will lead runners at next Saturday's Crim Festival of Races.
