Arizona’s Cosmo Dog Park may soon be using dog waste to shed some light.

The town of Gilbert is looking at teaming up with Arizona State University students to build a “digester” — like one we showed you last year — that will create methane gas to power, for starters, one street lamp at the park.

The project is scheduled to go before the Gilbert Town Council next month for approval.

Students from Arizona State University’s Polytechnic campus in Mesa hope to design and create the “dog waste digester,” according to the Arizona Republic.

The town is seeking a corporate sponsor for the project, estimated to cost $25,000.

Cosmo Park, which opened in 2006, draws more than 600,000 visitors annually and regularly shows up on lists of the nation’s best dog parks.

Former Gilbert Councilwoman Linda Abbott has been pushing the project after learning of the machine installed last year as a public-art project in a park in Cambridge, Mass.

(The Cambridge machine was a temporary project and is no longer in operation.)

Gilbert officials have held three meetings with ASU on the plan to design the machine, which would consist of a repository tank and digester.

It will be supervised by professor Kiril D. Hristovski, who will challenge her students to design a machine suited to Arizona’s climate, taking advantage of solar power.

“The principals of anaerobic digestion are the same,” he said. “We’re going to challenge the students to come up with innovative solutions that are unique.”

Rather than tossing poop bags into the park’s trash can’s, dog owners would collect their dogs waste in biodegradable bags, deposit it in the digester and turn a hand crank to stir the mixture so the methane rises to the top.
