TerraCycle, the company that got its start selling compost in recycled drink bottles, recently launched a Keyboard and Mouse Brigade <http://www.terracycle.net/en-US/brigades/keyboard-and-mouse-brigade.html>  that pays schools for things like old keyboards, mouse, and Web cams. As an additional incentive for participation, TerraCycle’s corporate partners have stepped up to offer grants and donations. Last year, Wal-Mart offered $125,000 in grants to the top-collecting schools in all of TerraCycle’s brigades, according to vice president of global communication Albe Zakes. One school used their grant funds  <http://morristowngreen.com/2011/03/18/woodland-school-celebrates-st-patricks-day-with-10k-of-green/> specifically to purchase classroom technology.
