The Columbus Zoo and Aquarium is one of the first organizations in Ohio to receive Ohio EPA's E3 Platinum Award. Their sustainability efforts include:
- Adopting a sustainability policy in 2008, including achieving carbon neutrality and zero waste status, reducing energy and water use, and increasing recycling rates.
- Calculating the carbon impact of their purchasing and operating decisions to help them prioritize decisions.
- Partnering with many organizations supporting regional, national and international conservation, scientific and sustainability efforts.
Their environmental stewardship and education projects include:
- Installing frictionless magnetic flux drives on water
pumps (98.5 percent efficiency at full power).
- Installing light-emitting plasma lamps.
- Upgrading their Holiday Wildlights Wonderland display to LED holiday lighting.
- Installing Ohio manufactured skylights inside their warehouse.
- Installing a closed-loop geothermal water system and water recycling system for the Polar Frontier exhibit.
They achieve a 65 percent waste diversion rate including composting and recycling by:
- Using non-potable water for irrigation.
- Locally sourcing animal feed.
- Composting food scraps and animal waste.
- Reusing many materials in their exhibits by recycling fibers, tires, old barn timbers, plastic, vinyl and concrete.
Their Mapori Restaurant:
- Is Four Star Green rated (one of three in Ohio) and LEED Certified.
- Their menu includes the carbon footprint of the items, so diners can make informed choices.
- Composts food wastes and uses bamboo dishes and trays.
- Uses a storm water polishing system before releasing storm water.
- Recycled 95 percent of construction material wastes and installed energy star appliances.
Sustainability projects implemented from 2011 to 2016 have a pay back of 2.2 years, with annual savings of more than $120,000. The Zoo recognizes that the projects have long lives and will continue to provide savings over time.
We will feature a case study of Washing Systems, our other platinum winner, in our next newsletter.
The E3 program provides four recognition levels: Achievement, Silver, Gold and Platinum. Any organization in Ohio may apply for membership. Applications are accepted annually and include both written and on-site evaluations. To be eligible, applicants must be in compliance with environmental laws and regulations.
