Cranberry’s efforts to promote recycling appear to have hit a resonant chord with local residents. Monthly figures provided by Waste Management show that while the volume of Cranberry’s trash going to landfill has grown by 4.7 percent from the corresponding tonnage in 2010, the volume of recycled material has gone up by 13.3 percent and yard waste has grown 6.3 percent. In May alone, the volume of yard waste increased from 345 tons in 2010 to 461 tons last month. Of the 13,072 total tons of residential waste hauled away last year, 22.7 percent was recycled material and another 20.1 percent was yard waste used for composting, resulting in a total of 42.8 percent recycled or recovered material. The national average is just 33.8 percent.
