Animal poo powers zoo
If you talk to Chuck Siegel, deputy director of animal management for the Dallas Zoo, he'll tell you that "poo and pee is our bread and butter."
Sounds a little gross, but it's totally true. Animal waste, rather than a useless byproduct, destined to take up space in a landfill somewhere, is instead going to be a source of energy for the zoo. Officials are implementing a plan that would take cardboard, tree limbs, and their never-ending supply of animal poop, and run it through a biogas generator that will help power several buildings.
With a total price tag of around $1 million, it's not exactly cheap. But given the amount of money the facility will save on power, zoo officials estimate that the project will pay for itself within ten years. Holy crap!
