A summary from Grist:
Home Depot announced Tuesday that it will collect compact fluorescent light bulbs and send them off to be recycled. The home-improvement behemoth hopes the new program will keep the bulbs, which contain a small amount of mercury, out of household trash and recycling bins. IKEA also collects CFLs for recycling but doesn’t have the market saturation of Home Depot; more than three-quarters of U.S. households are estimated to be within 10 miles of a Home Depot store. The company’s 1,973 U.S. stores will also switch to CFLs in light-fixture showrooms by the fall, a move expected to save it $16 million annually in energy costs.
