Now that recycling is mandatory in many states, it’s become even easier to sell, recycle or give away your unwanted hardware. Please read this informative article, posted August 8, 2012, from Computerworld.
And note this excerpt recommending e-Stewards: There may also be private recyclers near where you live which will accept or even pay for electronics to recycle.

A good place to find one is through e-Stewards, which sets high standards for electronics recyclers and certifies those that meet those standards.
