Zoos & Aquariums Detroit Zoo GreenFest in Royal Oak Chat with a zookeeper, take a tour of new sustainability programs and watch a chemistry demo on Earth Day, April 22, 2017, at the fifth annual GreenFest celebration at the Detroit Zoo in Royal Oak. « Previous Next » Amanda Rahn • April 14, 2017 Add Comment Total: 2 1 0 0 1 0 0 Celebrate Earth Day and make a furry friend or two at the Detroit Zoo during the fifth annual GreenFest celebration from 9 a.m. until 3 p.m. Saturday, April 22, 2017. GreenFest is part of the Detroit Zoo’s eco-friendly strategy Greenprint, which includes a water bottle phase-out program, electronic waste recycling and dozens of sustainability goals. The event will include a sustainability tour featuring the zoo’s new anaerobic digester, which converts animal waste into compost and uses the methane byproduct as an energy source at the animal hospital, and the permeable pavement, a type of paving that will improve stormwater management. To keep the little ones interested, check out chemistry demos, worm composting and zookeeper talks, too. A new art exhibition by Art Road Nonprofit, a program that offers “special arts activity classes, including supplies and an instructor, at no cost to elementary schools that lack art programs,” according to its website, will also be unveiled at the event. The art piece focuses on plastic waste pollution in the Great Lakes – but to see how the theme was used, you’ll have to make a visit to the zoo. The zoo’s Greenprint strategy for the future also includes zero waste to landfills by 2020, reducing water consumption by 20-25 percent and to educate and inspire guests about sustainability. The Detroit Zoo was awarded the Green Award in 2014 by the Association of Zoos and Aquariums for their efforts to promote and incorporate sustainability through Greenprint. Normal ticket prices are $14/adults, $10/children 2-14 and seniors 62+ and free/under 2. Parking is $7/vehicle. To get a discounted ticket for $9, bring in an old phone to recycle.
