Oklahoma company aims to turn waste into electricity

An Oklahoma-based startup company intends to turn trash into electricity, using a process that creates energy by speeding up the decomposition of waste materials.

He said turning waste material into energy reduces the need for future landfills.

Sexton said Evolution's technology should be able to reduce the cost of energy because there is no fluctuation in fuel costs.

“The cost of waste remains stable because cities actually pay what's called a tipping fee, or a cost per ton, to dispose of that waste,” he said. “So in our business model, we will receive the tipping fee, so they effectively pay us to power our facility, which means we can guarantee a levelized price for five years or 10 years per kilowatt of electrical energy.

“No other fuel source, no other technology can do that.”

Sexton said the company's technology can work on just about any scale, from something small enough to fit in the backyard to a facility big enough to power any entire city.

He said a plant to power a city the size of Oklahoma City would require about 15 acres of land because there would have to be room to store the waste material meant to be used as fuel.

Sexton said the company's process can generate one kilowatt of electricity from three pounds of waste, which shouldn't be hard to come by since the average American is responsible for 4.5 pounds of trash a day.

Wall said Evolution's technology is safe, without any radiation or risk of explosion.

The reaction shuts down after the feedstock is removed.

He said existing equipment can be used to set up a power plant using the company's technology.

“The only thing that is completely new here is the process itself,” Wall said. “That is completely new and we consider it a breakthrough.”
