Florida has implemented a 75% state-wide recycling goal to be achieved by 2020.  Recovery and recycling of construction and demolition (C&D) debris offers a significant potential contribution to meeting the 75% diversion goal.  The objectives of the research are to improve C&D debris inventory accuracy and recycling efficiency in the State of Florida through tasks directed at optimizing C&D debris inventory factors, evaluating future markets for recovered materials, and recommendation of best management practices.  Orange County (OC), Florida has received funding from the American Recovery and Reinvestment Act to develop a Solid Waste Integrated Resource Plan (SWIRP) which will initially focus is on C&D debris and Class III waste.

A debris inventory for OC for the years 2001 through 2009 was created by linking building permit information to debris generation multipliers.  It was estimated that the peak debris generation for unincorporated Orange County, was 240,000 tons which occurred in the year 2002.  After the economic downturn in 2007, debris generation decreased until the year 2009 when generation was the lowest at 60,000 tons.  Composition of the debris was also estimated and it was determined that concrete, drywall, and wood comprised the largest portions of the debris stream at 53, 20, and 12 percent respectively.  It was also found that three main barriers to recycling C&D in OC exist including a lack of established end markets, lack of infrastructure, and the fact that landfilling is inexpensive.
