Compact fluorescent light bulbs, long touted by environmentalists as a more efficient and longer-lasting alternative to the incandescent bulbs that have lighted homes for more than a century, are running into resistance from waste industry officials and some environmental scientists, who warn that the bulbs’ poisonous innards pose a bigger threat to health and the environment than previously thought.
