What We Do
Henry Doorly Zoo and Aquarium engages in a wide variety of sustainable
practices and is always looking for ways to conserve its resources.
boxes, telephone books, old clothing and other materials that are safe to reuse
are repurposed as enrichment items in exhibits throughout the Zoo. Items like these give animals new and
exciting ways to stimulate their senses and explore their enclosures.
In the Cat Complex, for instance,
discarded spices and perfumes are used to “mark” a predator’s territory. The
scents from the spice or perfume used will trigger the cats’ curiosity and natural
lighting are also used in various exhibits throughout the Zoo, specifically in Kingdoms of the
Night, the world’s largest nocturnal
exhibit. This practice helps mimic the natural habitat of each animal and
benefits their psychological well-being, in addition to conserving electricity.
Henry Doorly Zoo and Aquarium has also initiated practices outside of the
animal areas that allow the general public to partake in our cause.
just a few of the projects we’ve established:

Henry Doorly Zoo and Aquarium takes care of more than just animals. We also
tend to computers, copy machines, high-tech laboratory equipment and much more.

equipment, all of our old electronics are recycled through CP Recovery.
