E-Cycling Etiquette: How to Help

Americans toss out about two million tons of unwanted electronics annually, 1fouling landfills with toxic lead from old computer monitors, cadmium from leaking batteries, and more. But it is getting easier to discard responsibly.

Some charities repurpose old cell phones as lifelines for seniors and victims of domestic violence, and computers can go to underfunded schools. Reputable recyclers will properly scrap unusable electronics, though they sometimes charge a small fee. Donating newer models, on the other hand, can earn a tax deduction, so keeping old gadgets from gathering dust helps you and the environment. For more information on charities and recyclers, go to epa.gov/recycling.
