Freecycle

The Freecycle Network was started in May 2003 to promote waste reduction in Tucson's downtown and help save desert landscape from being taken over by landfills. This is made up of many individual groups across the globe where an electronic network provides a way people can "recycle" unwanted items. It's a grassroots and entirely nonprofit movement of people who are giving and getting stuff for free in their own towns. Each local group is moderated by a local volunteer and membership is free!
