FILE - In this Dec. 19, 2011 file photo, a boy selects garbage to recycle at the landfill Bordo Poniente on the outskirts of Mexico City. This dump was closed at the end of 2011 but the compost site within the dump continues to operate. Mexico City Mayor Miguel Mancera announced plans in September 2013 to control the foul odors that waft from the city's only compost plant at this landfill near the airport and to more aggressively recycle trash citywide.
