Roses are Red, Smartflower is Green

A 16-foot, metallic flower is now blossoming among the plants at the Detroit Zoo. This innovative ground-mounted solar panel system is called smartflower.

This high-tech addition is just another step on the Detroit Zoological Society’s (DZS) Green Journey to create a more sustainable future by using innovative practices that minimize our ecological footprint. It is the first of its kind to be installed not only in Michigan but in any zoo in the country.

Sunflowers turn their blossoms to face the sun to make optimum use of the light, increasing its growth rate. Since mother (nature) knows best, the creators of smartflower based the technology of this revolutionary system to function similarly to an actual sunflower, through the use of a GPS-based dual-axis tracker. The system features 12 solar panels – shaped to mimic petals – that follow the sun across the sky throughout the day. When the sun rises in the morning, the smartflower unfolds and aims its panels to the sky to begin producing energy. The petals will automatically close again when the sun goes down, storing the excess energy.

Since the smartflower is always at an optimal angle to the sun, it can generate 40 percent more energy than a traditional solar-panel system. The smartflower converts enough energy in one day to run an electric car for 62 miles, wash 17 loads of laundry or run three air conditioning units. The system at the Detroit Zoo is expected to generate more than 4,000 kilowatts of electricity annually, enough to power the Carousel and other areas of the Zoo.

The smartflower will be in full view during the DZS’s annual pre-Earth Day celebration called GreenFest at the Detroit Zoo on April 14, from 10 a.m. to 3 p.m.

The first 1,000 guests to visit the anaerobic digester educational display will receive a token for a 5-gallon bucket, courtesy of The Home Depot Foundation, to be filled with free Detroit Zoo Poo – an herbivore compost processed in the DZS’s anaerobic digester and produced in partnership with Detroit Dirt. The digester – the first in Michigan and the only zoo-based system of its kind – annually converts 400 tons of animal manure and other organic waste into a methane-rich gas that helps power the Ruth Roby Glancy Animal Health Complex.

The event will also include a sustainability tour as they learn about the DZS’s many green initiatives. Guests can learn about permeable pavement, composting, recycling, preventing bird strikes, making a home more energy efficient and building backyard wildlife habitats. They can also explore farm-to-table food options at Pure Greens Café, widen their science knowledge during chemistry demonstrations, and take a green pledge, committing to joining us on our Green Journey.

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.
