Zoo’s animal waste to be transformed into power, fertilizer

The Detroit Zoo is developing an anaerobic biodigester that will convert animal waste and other organic material into fertilizer for use on the grounds and into methane-rich gas that will help power facilities at the zoo. The work is expected to save tens of thousands of dollars in energy and waste disposal costs. A crowdfunding campaign is underway. WWJ-TV/WWJ-AM (Detroit) (4/20), The Detroit News (4/21)
