There is an organization called freecycle with chapters across North America.
It works on the theory that one man's trash, is another man's treasure.
Through Freecycle, you can take your unwanted / unneeded materials and donate it to someone who has a need for it. People post what they have, and receive emails from those who might need it. It's a great way to help others, and help the environment as well, because we won't have so much perfectly good material filling up our nation's land fills.
You can find a local Free-cycle group in your area by visiting
