Phone companies want to help you recycle, and get value out of, your old mobile devices. With them, they can sell refurbished devices or reclaim valuable materials for recycling.
Best Buy also offers free e-cycling for many different kinds of electronics beyond just phones. They might not pay you for them, but they do try to make it as easy as possible to responsibly e-cycle home appliances and other electronics.
It’s good for the planet, good for them, and good for you! Check out the links below for more info. And click here to learn more about e-waste!
