New York turning food waste into compost, gas

New York

NEW YORKERS already have blue and green bins for recycling glass, metal, paper and plastic. But now brown bins for organic waste are starting to appear all over the city. These plastic totems are part of the city's multimillion-dollar campaign to cut down on greenhouse gas emissions and reliance on landfills, and to turn food scraps and yard waste into compost and, soon, clean energy.

In the 19th century, the city had a simple method for dealing with organic rubbish: It enlisted scavenging swine to nose through the gutters for leftovers. Now, the city is employing the primal chemistry of decay.
