Hewlett-Packard has expanded the scope of its technology recycling program, the HP Consumer Buyback and Planet Partners Recycling Program. The initiative will dole out cash for any of the following (provided there is some value): PCs, monitors, printers, digital cameras, personal digital assistants or smartphones. If the piece of tech is too old, HP will recycle HP- and Compaq-branded items for free. (There may be a nominal fee if the product has no value AND it isn't from HP or Compaq.)

To date, HP has collected more than 1 billion pounds of old electronics. Its goal is to collect 2 billion pounds by 2010, and the company says it's on track to reach that amount.
HP's recycling and refurbishment partner for this effort is Market Velocity, which you might want to check out if you're trying to get rid of multiple pieces of technology.
