required to ensure any separated wood was free of unwanted materials. Our current incentive fee of $12 per ton for separated wood attracts almost no separated loads of wood waste. Wood markets are so depressed that in most cases, we must pay to grind the wood and load it into trailers before it is marketable. Typical market value is about $10 per ton delivered. Grinding costs routinely exceed $10 per ton. The nearest solid fuel boilers are at least 40 miles away. The one whole -board market we have identified in Charlotte requires that lumber be free of nails and over 4 feet long and pays nothing for the wood. Wooden shipping pallets must be mostly intact, to the point where they are stackable and staff must stack and sort them by size once they are deposited at the landfill. We are paid a price of $0.50 for only one popular size of pallet that makes up an average of about 50% of the load. The other sizes are taken at no fee. We must load them and the company hauls them to Greensboro. Drywall must be source - separated and free of contaminants. Typical handling includes dumping drywall on a covered concrete tip floor, screening for contaminants, loading into a shipping container, keeping drywall dry and shipping a minimum of 35 miles one -way to a market in Goldston. The tip fee is $12 per ton their gate plus the hauling costs. We estimate a development cost of about $100,000 for a drywall processing facility and transportation equipment. Additional staff requirements would be determined by the development of other operations situated in proximity to a drywall facility. Inert Debris: Recycling of this material costs about $7.00 per ton according to national studies. Locally quarried stone for road base and other construction applications is typically available for less than this cost. Dirt which would compete with the fines or small particles produced as a by- product in any C &D processing operation is cheaper and more readily usable than fines. Any separated inert materials such as brick, block concrete, must be crushed for market and meet various engineering specifications. It must compete against locally quarried, high quality rock products. State and local engineering specifications often limit the applications of crushed inert products to very low impact areas such as under sidewalks. Other: There are niche markets for plastic buckets, free of residues and debris, vinyl pipe and siding, and certain types of carpeting. Market specifications are rigorous. We receive relatively small amounts of these materials and source separation would entail a large storage and preparation area with little material potentially available for diversion. No viable market has yet been identified for post - consumer shingles. It is possible to use a series of regulations and economic incentives to cause some source - separation. The per ton cost to process these materials at a central site is probably less than if a centralized facility to process mixed C &D were built. Key issues: Tolerance levels for receiving materials as source separated require rigorous inspection. 28
