Animal Waste Will Soon Become Energy at the Detroit Zoo

At the Detroit Zoo, animal waste will soon turn into energy through an anaerobic biodigester, which will help power the Ruth Roby Glancy Animal Health Complex and save on the zoo's annual energy costs.

The project will begin this spring and will be completed by the end of the year, according to Detroit Free Press. 

The process will convert animal manure along with other waste into methane gas, which will help power the zoo.

The conversion process will not only create energy, the biodigester "will convert manure into compost that will be used to fertilize animal habitats, gardens and public spaces," according to Detroit Free Press. 

Will other zoos adopt the same concept?

  • It won’t destroy hormones and antibiotics, if they are being used on the animals. Heavy metals are also not removed. Given those concerns it’s a great idea.
