Detroit Zoological Society Honored for Environmental Contributions

In recognition of our ongoing efforts in environmental sustainability, the Detroit Zoological Society (DZS) recently received the Keep Michigan Beautiful award. This honor, bestowed by Keep Michigan Beautiful Inc., highlights contributions we’ve made to preserve the land around us and create a better future for all.

This includes building an anaerobic digester, which will annually convert 500 tons of animal manure and organic food waste into a methane-rich gas that will power the Detroit Zoo’s animal hospital. We are also keeping 60,000 plastic bottles out of the waste stream annually by no longer selling bottled water on Zoo grounds. As part of this effort, we have free refillable filtered water stations throughout the Zoo and offer affordable reusable water bottles for guests. We also encourage visitors to purchase wildlife-themed reusable bags at our gift shops as we no longer provide plastic bags for purchases in order to reduce plastic waste. We’re incorporating permeable pavement into new visitor walkways – and even a parking lot – reducing storm water runoff and filtering pollutants. All of these efforts contribute to keeping Michigan beautiful.

All of these actions are guided by the Greenprint, a green roadmap that helps us refine and improve our facilities and daily practices, develop new policies and programs and improve green literacy and action in our community.

Porous Pavement Protects Sewer Systems

Observe storm water disappear right before your eyes through the environmentally beneficial phenomenon known as permeable pavement. Constructed of porous materials, it allows for the passage and filtration of water. While “normal” asphalt and concrete tend to be a less expensive option, permeable pavement has many benefits that help our environment, making it a better – and greener – alternative. During heavy rainfall, sewer systems tend to get overwhelmed and may result in flooding, along with basement backups and polluted waste water. To combat this, the porous material captures the runoff and filters out any pollutants. This collection of rainwater also helps to recharge groundwater and reduce surface temperatures, which is extremely beneficial to the surrounding ecosystems.

The Detroit Zoological Society (DZS) is paving the way for a more sustainable environment by utilizing this progressive green design. We first implemented permeable pavement at the Detroit Zoo in 2015 with the construction of the Cotton Family Wolf Wilderness, which features visitor walkways made with porous material. As we continue to improve the infrastructure at the Zoo, we are incorporating permeable pavement within our design plans, such as a parking lot we constructed in 2016 near the main entrance with 215 additional spaces, as well as a new visitor walkway outside the Edward Mardigian Sr. River Otter Habitat added in 2017.

Join us on our Green Journey! By implementing sustainable storm water infrastructures, we can help relieve the influx of water into the sewer system. Try disconnecting your downspouts and channel the water into your lawn or garden, plant a rain garden with native Michigan flowers and/or harvest rain water – these are all cost-effective ways you can help too.

GreenFest – A celebration of Earth Day

“You cannot get through a single day without having an impact on the world around you. What you do makes a difference, and you have to decide what kind of difference you want to make.” – Jane Goodall

For nearly 50 years, millions of people around the globe have been celebrating Earth Day. Held annually on April 22, Earth Day represents the birth of the modern environmental movement and a worldwide demonstration of support for environmental preservation. As a leader in sustainability, guided by our award-winning Greenprint initiatives, the Detroit Zoological Society (DZS) annually holds GreenFest at the Detroit Zoo as a celebration of Earth Day. This year’s event is scheduled for Saturday, April 22, from 9 a.m. to 3 p.m.

The event is free with Detroit Zoo admission and includes a variety of engaging activities as well as a sustainability tour – complete with 10 stations that showcase our Green Journey. Upon arrival, guests will be given a “passport” that can be stamped at each of the stations. The passports were created by DZS staff using recycled millage signs and can be taken home and used as a journal.

These stations will provide guests with information about our anaerobic digester – the first zoo-based system of its kind that will annually convert more than 500 tons of manure into electricity that will power our animal hospital – as well as permeable pavement, bird-strike reduction, vehicle maintenance, recycling and native-species gardening, among others. In addition, we will be sharing information on how visitors can incorporate these initiatives at home. For example, not everyone can build an anaerobic digester in their backyard, but many can choose to compost their food scraps; we will provide information on how to start doing so.

The first 3,000 guests who complete the sustainability tour will receive a reusable bag to help them as they join us on our Green Journey. There will also be a station for folks to take our Green Pledge – several pledges will be selected in a raffle to win a Detroit Zoo reusable water bottle.

GreenFest will also include chemistry demos, worm composting education, zookeeper talks, and much more.  Additionally, a travelling art exhibition by ArtRoad Nonprofit will be unveiled during the event, illustrating the impact of plastic pollution in the Great Lakes.

Attendees who bring a cell phone for recycling to GreenFest will receive a reduced admission price of $9. Admission is free for DZS members.

The DZS will also host Green Day at the Belle Isle Nature Center on April 22 from 10 a.m. to 2 p.m. Green Day will feature crafts, games, storytelling, zookeeper talks and exhibits by local conservation groups.

Both GreenFest and Green Day events are initiatives of the DZS Greenprint, a strategic plan to refine and improve green practices and facilities at the Detroit Zoo and Belle Isle Nature Center, incorporate sustainability in all policies and programs and improve green literacy and action in the community.

Sustainability and Conservation Go Hand-in-Hand

The Detroit Zoological Society’s (DZS) award-winning sustainability initiatives go hand-in-hand with our commitment to wildlife conservation – every step we take to reduce our carbon footprint serves to protect the habitats of animals around the globe.

Wildlife are facing great challenges – from climate change and habitat loss to poaching and the exotic animal trade – leaving many species threatened, endangered or teetering on the brink of extinction. Human impact on the Earth has, in many cases, led to these dire situations they are in. More than 40 percent of all amphibians are at risk. From snow leopards to snails and from penguins to polar bears, the DZS is actively involved in wildlife conservation efforts worldwide – in the last two years alone, we were engaged in projects on six continents.

We have the power to make a difference. That’s why our inaugural Wildlife Conservation Gala on Saturday, March 18, is themed “Making a Difference”. All of us can take steps in our own lives to help reverse the crisis many animals are facing. It is our hope that our community will be motivated to join us on our Green Journey and commit to a better future for all that share this magnificent planet.

Our award-winning Greenprint initiative is a strategic plan that guides our operations and all that we do toward a more sustainable future. Our efforts include discontinuing the sale of bottled water on Detroit Zoo grounds – previously the No. 1 seller at zoo concessions – keeping 60,000 plastic bottles out of the waste stream annually. We also no longer provide plastic bags at our gift shops or souvenir stands; visitors are encouraged to bring their own bags or purchase wildlife-themed reusable bags.

We built the first zoo-based anaerobic digester in the country, which will annually convert more than 400 tons of animal manure into methane-rich gas to power the Detroit Zoo’s animal hospital. We recently unveiled a new parking lot that uses a progressive green design, reducing storm water runoff and improving water quality by filtering pollutants. Additionally, our operations are powered with 100 percent renewable electricity from wind farms, thanks to the support of the ITC Holdings Corp.

Our goal is to inspire others to join us on our Green Journey as we continuously look for ways to reduce our ecological footprint. By downloading our Shades of Green guide, you’ll find a number of actions you can do at home, including:

  • Switch to a reusable water bottle and reduce the amount of unnecessary plastic pollution
  • Bring reusable bags with you to the grocery store
  • Turn off the lights when you leave a room
  • Recycle
  • Plant native species in your garden to create a natural habitat for pollinators such as bees and butterflies

Please also consider joining us on March 18. By supporting the Wildlife Conservation Gala, you’ll help to ensure the long-term survival of critically endangered amphibians, reptiles, birds, mammals and invertebrates that represent the diversity of life on our planet.
