When you're following your dog with a full baggie, it's hard imagining poop being anything but waste. However, entrepreneurs around the world are finding ways to turn dog dung into a source of energy.
This methane digester turns the poo to energy. Pet owners collect the waste in a biodegradable bag, and toss it into the digester. Microbes and water break down the poop, and - voilà - methane gas rises to the top ready to be burned!
The Park Spark Project, pioneered by Matthew Mazzotta, uses the methane gas to light an eternal flame lamp post in public parks. Then, it's up to the community to come up with a creative idea for using the energy.
Programs like this are especially important since dog waste in landfills emits methane — which becomes a potent greenhouse gas — into the atmosphere. However, when methane is burned, it separates into carbon dioxide and water. This impacts the atmosphere significantly less, and even earns carbon credits. Could programs like The Park Spark Program be the future of poop? We hope so.
