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.
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.
“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.

Dog feces is being used to keep the lights on — well, one light, anyway – at a park in Cambridge.
Conceptual artist Matthew Mazzotta, through an MIT-funded project known as Project Park Spark, is the brains behind the scheme, in which a “methane digester” is used to to convert freshly scooped dog waste into methane.
Dog owners simply collect their dog waste in a special biodegradable bag and throw it into an air-tight cylinder. The feces are broken down by anaerobic bacteria. The process produces methane, which is then released through a valve and burnt as fuel — in this case to power an old-fashioned gas-burning lamppost in the park.
Mazzotta is open to other suggestions on how to use the flame, and suggestions have included a teahouse, popcorn stand and shadow-projection box.
It’s a pretty brilliant use of dog waste, which, when it goes into landfill, releases methane into the atmosphere. Harnessing it is a far better idea, considering methane is a potent greenhouse gas more than times more harmful than carbon dioxide, WIRED reports.
Mazzotta hopes to install permanent underground digesters in parks throughout the United States.
