Answer the Call of the Wild!

Orangutans could be the first great ape species to become extinct in the wild within the next 10 years. Bring your used ink cartridges to the guest services counter at the main entrance of the zoo and help Denver Zoo support orangutan conservation.

You can also mail your cartridges to:
Denver Zoo
Attn: Ink Cartridge Recycling
2300 Steele Street
Denver, CO 80205


Why should I recycle my used ink cartridge?

Rather than throw a used ink cartridge away, guests are encouraged to donate their ink cartridges to Denver Zoo, who has partnered with The Orangutan Conservancy to raise funds to help protect the world’s most endangered great ape, the orangutan.

• Help the environment by recycling waste that would otherwise end up in the landfill.   Currently 600 million ink jet cartridges are sold on an annual basis in the United States and 90% of them end up in landfills. 
• Provide funds that will benefit orangutan conservation.

An ink cartridge recycling company will pay Denver Zoo for each working empty ink cartridge.  Funds from the program will be delivered from Denver Zoo to the Orangutan Conservancy, a non-profit dedicated to the conservation of orangutans and their habitat through preserving the remaining orangutan populations and by promoting the changes that are needed to preserve their natural habitat. The Orangutan Conservancy accomplishes these goals by providing funding and other support to various projects throughout Indonesia and Malaysia.
