The reality is that thousands of schools, community-based organizations, and other groups can get much good use out of your old computer. Even if it is no longer satisfactory for you, your computer may still do a world of good to others. Contact your local schools, community groups, and senior centers. Keep in mind that your computer is no friend of the environment. Though the PC industry is thought of by most people as green, the reality is that the industry does a lot of polluting.
Computers contain hundreds of harmful metals, acids, and plastics.
If you care about the environment, you need to think about proper disposal of your computer. Encourage computer manufacturers to adopt take-back programs. Find a home for your computer with a national nonprofit group. For information on passing your computer along to a charity or school that could put it to use. Use your zip code to find local recycling options for computers and other materials.
