But if you work in a home office or can't locate someone who collects the empties, there's a much better option than tossing empty inkjet cartridges in the trash and filling up landfills. The US Postal Service (USPS) is testing a service that allows consumers to send empties (as well as small electronics) for free to a company that recycles them.
Free mailers for the "Mail Back" program can be found in 1,500 post offices in and around Washington, DC, Los Angeles, Chicago, and San Diego, according to the USPS. If the program is successful, it says it will roll it out nationwide. So support the program and help the environment!
