We're a nation of gadget lovers. Our computers and cellphones and MP3 players rapidly become outdated, obsolete, or simply not-so-cool anymore, and our consumer urge is to simply replace them instead of fixing or upgrading. The EPA estimates that 2.25 million tons of electronics were disposed of in 2007, and 80 to 85% of them ended up in the landfill instead of being recycled. That's quite a bit of potentially recyclable toxic waste being buried in the earth. We can do better than that. So how do you find out what to do with your old gadgets?

The National Center for Electronics Recycling is a 501(c)(3) non-profit organization dedicated to developing and enhancing the national infrastructure for the recycling of used electronics in the U.S., and their website is full of helpful links to find a recycler for your stuff.

My Green Electronics has a search-by-zipcode guide for electronics recycling, as well as plenty of links for charities and community organizations that will take your gadgets for reuse.

Earth911 searches by product and zip code for recyclers near you, and hosts a wealth of information about how electronics are recycled and why we should choose recycling instead of throwing gadgets in the landfill.
