Detroit, MI, Aug 19, 2009 — As municipal landfills were closed and capped back in the 1980s and 90s, communities across the US built big incinerators to get rid of the trash. Some, like St. Lawrence County, decided "no" for environmental and economic reasons. But many of the massive furnaces were built, financed by bonds and waste contracts just now being paid off. Now that those debts are off the books, some municipalities are having to think, all over again, about whether burning trash makes environmental and economic sense. Sarah Hulett reports.
