Greenprint: Team Spirit Empowers Sustainable Business Practices

Reducing our ecological footprint, creating a more sustainable future and protecting wildlife and wild places – these are initiatives that are near and dear to the staff and board of the Detroit Zoological Society (DZS). Guided by the Greenprint, a strategic plan for operations at the Detroit Zoo and Belle Isle Nature Center, our goal is to inspire others to join us on our Green Journey as we continuously look for ways to live and operate in more sustainable ways. To accomplish this, we started from within.

The DZS Green Team was founded in 2002 – before the Greenprint was even conceived – to help minimize the ecological footprint of our operations and to educate staff and visitors about choices that enable us to live a more Earth-friendly lifestyle. Being a part of the team is voluntary; it is comprised of representatives from every DZS department who share their commitment, expertise and time to make the Zoo a greener place for staff, visitors, animals and the planet. The Green Team was a strong advocate for development of Greenprint goals and objectives and has been instrumental in carrying out those policies and procedures.

Because of our passion and accomplishments in these areas, we have become a regional leader in sustainable business practices.

Recent initiatives include 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 Zoo’s animal hospital. We are also keeping 60,000 plastic bottles out of the waste stream annually by no longer selling bottled water – previously the No. 1 seller at Zoo concessions. 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. We’ve incorporated permeable pavement into new visitor walkways and a parking lot, reducing storm water runoff and filtering pollutants. These are just a few of the steps we’ve taken on our Green Journey thus far.

Green Team members have assisted with projects ranging from educating Zoo visitors about the anaerobic digestion process to sorting trash at zero-waste events. Staff recently volunteered at the 2017 Metro Detroit Youth Day on Belle Isle, which drew more than 37,000 attendees. The Green Team educated participating children on the value of using a refillable water bottle in order to reduce plastic waste in Michigan. More than 4,000 Detroit Zoo refillable water bottles were given to the children during this event, thanks to a generous grant by the Fred A. and Barbara M. Erb Family Foundation.

DZS staff feel so strongly about plastic reduction that we have incorporated this initiative within many of our events. Our annual 5K/10K/Fun Walk, Run Wild for the Detroit Zoo, was one of the first races in the country to eliminate bottled water – instead, refillable bottles filled with fresh, chilled water are provided to participants after the race. Assistance from our Green Team was invaluable as we worked to accomplish this important sustainable task. Prior to the 2016 event, volunteers filled more than 4,200 water bottles for the racers. We are gearing up for the 2017 event on Sunday, September 10 – registration is open. Run Wild raises critical funds for the Ruth Roby Glancy Animal Health Complex and veterinary care for the animals at the Detroit Zoo.

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.

Greenprint: Hosting Eco-Friendly Celebrations

Americans amass 258 million tons of garbage annually, according to the Environmental Protection Agency. And while 35 percent of that is recycled or composted, the remaining 169 million tons of trash ends up in landfills – the breakdown of which creates toxic gases that pollute our air and water and contribute to global warming. An even more staggering statistic is that in Michigan, only 15 percent of waste produced annually is recycled – far less than the national average.

We can all take steps in our daily lives to reduce the amount of waste we are creating. At the Detroit Zoo, we no longer sell bottled water or provide plastic bags at zoo concessions. We’re converting 500 tons of animal manure annually into energy to power our animal hospital. And we are working toward a lofty goal of becoming an entirely waste-free zoo – which is not an easy task.

It’s all a part of this journey we’re on – our Green Journey – to create a more sustainable future and protect the wildlife and wild places around us. We encourage you to join us. Download our Shades of Green guide and learn what actions you can take to lighten your impact on the Earth.

With summer upon us, barbecues, picnics and pool parties are in full swing as we enjoy the beautiful weather. But oftentimes with these events, we generate a great deal of waste. Disposable paper plates and paper napkins are common, as are disposable plastic cups and cutlery. By reducing cleanup time, the event becomes easier on the host; however, the waste becomes significant. Consider holding a waste-free event and ask your guests to embrace the effort.

Here are some tips for hosting a zero-waste event:

  • Decorate with flowers and plants, which can be composted when the event is over.
  • Use cloth napkins that are easy to launder.
  • Serve food with reusable dishes and cutlery.
  • For a unique party favor, go to a second-hand store and purchase vintage-inspired plateware and encourage guests to take their plate home.
  • Forget the red solo cups; use glasses and purchase an erasable marker to write guests’ names on their glass.
  • Consider composting. If you do, be sure to educate your guests on what items can be composted before they scrape the food. Also, if they know the goal is to be waste-free, they may be more conscientious of how much food they put on their plate.
  • Get creative and have fun with it – zero-waste parties can be beautiful, along with being greener!

Portions of our annual 21-and-older fundraising gala, Sunset at the Zoo – this Friday, June 16 – are going to be waste-free. Guests will receive a commemorative glass with their champagne welcome that they can use throughout the evening as they sample drinks and dishes from more than 50 restaurants and distributors and enjoy live entertainment. Reusable bags and our Shades of Green guide will also be gifted to guests. In addition, food waste generated from the event will be composted in our anaerobic digester. This is all a part of this year’s theme of “Green is the New Black” – which celebrates our award-winning sustainability initiatives. But Sunset at the Zoo is more than just a great party – it raises funds that are critical to supporting the Detroit Zoological Society and our mission of Celebrating and Saving Wildlife.

Greenprint: Using Compost to Fertilize Gardens

Spring fever has officially set in and naturally, one of the things on many people’s minds is gardening. We recommend incorporating “gardener’s gold” as you prep your plots this year: Composting can help you save money while also reducing waste and improving the quality of your soil. As you work on cleaning up your yard, you can add the materials to a compost bin and toss in your organic food scraps – they’ll naturally decompose to create a nutrient-rich fertilizer that will help you grow healthy plants.

There are many benefits to composting:

  • Reduce landfill waste. Nearly 30 percent of the garbage that is sent to Michigan landfills could actually have been composted.
  • Decrease the amount of greenhouse gases produced by food waste sent to landfills.
  • Improve soil quality by adding compost to gardens.
  • Reduce the use of chemical fertilizers.
  • Save money – use your own compost instead of purchasing fertilizer from a store.

How to compost at home:

  1. Choose an area in your backyard with good drainage and shade.
  2. Start the pile with a layer of twigs or mulch as a base.
  3. Add a thin layer of “green” materials, e.g., fruit and vegetable peelings, grass clippings or weeds.
  4. Cover with a layer of “brown” materials, e.g., dry leaves, twigs, paper or straw.
  5. Moisten your compost pile.
  6. Repeat steps 3, 4 and 5.
  7. Turn the pile every four to six weeks.

*Avoid placing meat or dairy products in compost.

You’ll be able to use the compost in your gardens in three or four months. If you’d like to speed up the process or don’t have room for an outdoor compost pile, you can purchase a batch-style composter for under $100 at most hardware stores. These bins can be placed on decks and take up less space in your yard.

For more in-depth information on the benefits of composting as well as detailed instructions on how to compost, you can refer to https://www.epa.gov/recycle/composting-home and www.howtocompost.org.

We’re breaking down organic matter at the Detroit Zoo on a much grander scale! More than 500 tons of waste is generated annually by the animals that live here. So, in order to reduce our ecological footprint and move closer to reaching our goal of becoming waste-free, we constructed an anaerobic digester on Zoo grounds. Anaerobic digestion is a process by which plant and animal materials are broken down, producing a methane-rich gas. This renewable energy will be used to power the Ruth Roby Glancy Animal Health Complex at the Detroit Zoo, saving us $110-120,000 a year in energy costs. By diverting manure and food waste from the landfills, we are also reducing the greenhouse gases which contribute to climate change – methane and carbon dioxide – in the atmosphere. The remaining nutrient-rich material will be used as compost to fertilize the gardens throughout the Zoo’s 125 acres.

Next time you are at the Zoo, check out our new sign detailing the anaerobic digestion process and contemplate the impact of keeping 55 wheelbarrows of manure each day out of the landfills!

Join us on our Green Journey and begin composting this spring! Take a look at the many other steps you can take to help us create a more sustainable future by downloading our Shades of Green guide.

Greenprint: Trash from Great Lakes Turned into Art at Detroit Zoo

The Detroit Zoological Society (DZS) recently partnered with ArtRoad Nonprofit, an organization that provides art-based activities, instruction and supplies to elementary schools in southeastern Michigan that are lacking in art programs.

In addition to the incredible educational opportunities this organization shares with hundreds of students annually, they also reuse donated items within their art projects in order to reduce waste. This aspect of the organization especially appeals to us as we continue with our Greenprint initiatives and award-winning efforts to create a more sustainable future.

I recently had the opportunity to volunteer in an ArtRoad classroom, where we worked with students on repurposing various items into works of art. The students greeted me with a warm welcome, and knowing that I work at the Detroit Zoo, created penguin art using recycled vinyl for the birds’ feet.

In turn, I provided the students with journals that DZS staff created using recycled millage signs. We hope these journals will help the budding artists capture their imaginations on paper.

Recently, ArtRoad collaborated with the Alliance for the Great Lakes to collect recyclable materials and debris from the shorelines of Lake Michigan. Using these items, more than 150 elementary school students spent two months creating five fish sculptures, one for each of the five Great Lakes. This effort aims to bring awareness about the effects plastic pollution has on freshwater ecosystems.

We are excited to be able to share this educational and impactful project with Detroit Zoo visitors – these fish sculptures will be on display April 22-July 9. It’s only fitting that the art exhibition will be unveiled during GreenFest, our Earth Day celebration, and will be on display during Sunset at the Zoo, our annual fundraising gala that carries a theme this year of “Green is the New Black”, celebrating our groundbreaking efforts in sustainability.

Our recent initiatives include discontinuing the sale of bottled water on Zoo grounds – keeping 60,000 plastic bottles out of the waste stream annually – and building an anaerobic digester which will convert more than 500 tons of animal manure annually into methane-rich gas to power the Zoo’s animal hospital.

Be sure to check out the ArtRoad exhibition on your next visit to the Detroit Zoo!

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.
