Donate Your Old Cell Phone
FONZ (Friends of the National Zoo) has partnered with ECO-CELL, a fundraising program designed to recycle used cell phones, batteries and accessories. One-hundred percent of the funds raised will go to FONZ. ECO-Cell ensures environmentally responsible recycling procedures of used cell phones and their accessories, keeping hazardous materials contained in cell phones out of landfills.
This program helps limit coltan (used to coat components of cell phones) mining in Congo, home to endangered gorillas and elephants. Reducing the demand for coltan will help save these animals and their habitat. The U.N. has reported that in the past five years, the eastern lowland gorilla population in Congo has declined 90%. Reducing the demand for coltan will help save these animals and their habitat.
ECO-Cell pays up to $15 for every working cell phone and recycles the remaining phones. Seventy percent of the phones collected will be used by first-time, low-income users abroad or by selected local organizations, such as battered women’s programs for emergency use (911 calls).
Collection boxes have been distributed throughout the National Zoo. A box is available in the Zoo's Visitor Center. If you'd like to give me your phones, I'd be more than happy to take care of it for you.
