The U.S. Postal Service has created a new service that will let you recycle cell phones, iPods and other electronics, as well as printer inkjet cartridges, for free by mail.

Currently the program is undergoing a trial run focused on ten cities, including Washington D.C., Chicago, Los Angeles and San Diego. The "Mail Back" program is being instituted at 1,500 post offices that will offer special free envelopes. You can drop in your recyclable electronics item and mail it without postage.

The items will go to Clover Technologies Group, which recycles, remanufactures and remarkets inkjet cartridges, laser cartridges and small electronics. You can take as many "Mail Back" envelopes as you want, and use them to mail your electronics from anywhere.

If successful, the program will go nationwide in the fall.
