Recent rains in the Lexington area have caused green growth in neighborhoods. That has increased the disposal of grass clippings and other yard waste. Workers in the city’s Division of Waste Management have noticed an increase in household waste and yard waste in plastic bags in the city’s plastic Lenny cart containers. The use of plastic bags and other non compostable items interfere with the composting process. All household waste should be placed in the Herbie container. Composting reduces the cost to send waste to a landfill. From July of 2011 through June of 2012, almost 22 thousand tons of yard waste was composted, which reduced landfill costs to taxpayers by more than 610 thousand dollars.
