Meet "Big Trash"
Over the long run, keeping stuff like tree limbs and compostable waste out of landfills is good for cities. There's only so much space in a landfill and getting more land is extremely expensive. So why haven't more cities hopped on the curbside composting bandwagon, or at least banned yard waste from landfills? There's probably a lot of factors that go into those decisions, but one, apparently, is the influence of large, private companies that handle waste collection
and see the diversion of re-usable waste as a detriment to their income. (Via Chris Tackett)
