The Detroit Zoo is looking to turn 400 tons of animal waste generated every year into thousands of dollars in savings.
The Detroit Zoological Society and the Michigan Economic Development Corporation have launched a crowdfunding campaign to raise enough money to build a biodigester, ABC News reports. The biodigester would turn all of that manure and other organic waste into methane-rich gas that could help power the Ruth Roby Glancy Animal Health Complex, saving the zoo between $70,000 to $80,000 annually.
