production, and as bedding material in dairy operations. Although local and state waste officials are currently neither recommending nor prohibiting agricultural uses of construction waste gypsum wallboard, approximately 17,000 tons of scrap gypsum wallboard was recycled for agricultural use in the region in 1993. Recycling of scrap drywall for use in new gypsum wallboard is currently no longer an option in the metro Portland area. Although a plant in Fife, Washington (90 miles north of Portland) recycles scrap wallboard for use in the manufacture of new board, successful arrangements to recover significant amounts from the Portland area have not been made. Apparently, the combined processing and transport costs make it difficult to cost-effectively recover the gypsum board waste unless quantities are large enough to gain some economies of scale in its recovery. Metro Regional Services feels that much more gypsum wallboard waste could be recovered from residential construction than is currently being recovered. There is strong interest in the recovery of corrugated cardboard by most waste haulers, construction recycling services, and local solid waste officials because of the relatively high value of the material and the well-established markets for the material. A significant part of its recovery is accumulating enough material to market it directly and get a better price by eliminating intermediate handlers. The current price in the Portland area is approximately $50/ton as sold to an intermediary. Prince George's County, Maryland Lori Scozzafava, Chief of the Recycling Division for the Maryland Department of the Environment (MDE), described the current status of construction and demolition (C&D) disposal and recycling from a regulatory standpoint. 1) Construction waste materials separated at the source (in this case, the construction job site) are not regulated as solid waste and are classified as recyclables. Source-separated materials are not regulated by the state and no permit is required to handle, transport, or process these materials. On the other hand, construction waste that leaves the job site commingled and is taken to another location for separation is considered solid waste. Only permitted landfill operations may handle these materials. Because the permitting process for solid waste handling can be expensive and lengthy, Ms. Scozzafava encouraged looking at construction waste recovery that involved source separation. 2) Rubble fill (the Maryland term for C&D landfills) design requirements are slated to be upgraded under new regulations with a liner requirement becoming effective by October 31, 1996. These new regulations are still in the development stage and anyone may comment at this time. For a copy of the pertinent new regulations contact MDE and ask for MDE #631-3424. 3) The state has compiled a directory of both wood and corrugated cardboard recycling markets. Copies of these directories were given to the NAHB Research Center project manager. In later discussion, Ms. Scozzafava indicated interest in MDE involvement in the creation of a recycling directory created specifically for construction waste materials. Barbara Yuhas, Recycling Chief for Prince George's County, stated that the County currently accepts source-separated, "untreated" wood waste for eventual sale to mulching operations at a reduced tipping fee of $25/ton. This facility evidently does not normally receive new
construction wood waste due to the confusion about the acceptability for mulch of engineered wood products. Bill White of United States Gypsum (USG) in Baltimore outlined current USG activities: Their Baltimore plant currently recycles approximately 1,000 tons a month of internal plant waste, consisting of culled boards and cut-off material. A recycled content of 2- 3% based on recycling plant cull is fairly typical of U.S. gypsum wallboard manufacturing plants. a a USG accepts another 500 tons per month of new construction waste wallboard in a pilot project. This construction cut-off waste comes from local manufactured housing ("mobile home") plants and a few general construction or drywall contractors. The current recycling process at the Baltimore USG plant could handle another 3500 tons per month, if arrangements could be made with MDE inspectors for the storage of clean, construction, cut-off waste gypsum wallboard. USG has 140 building product distribution centers nationwide that could become involved in the recovery of waste gypsum wallboard if cost-effective methods of handling the materials can be established. Backhauling of waste gypsum wallboard from distribution centers has been mentioned in the past by more than one drywall manufacturer. Larry Cartano of Pleasant Companies represented both the Ritchie Reclamation and Landfill operation and Environmental Alternatives, Inc. (the construction waste hauling company that participated in the waste assessment of the TABCO home). Permits have been received for the construction of a building to house material recovery of construction waste at the Ritchie Landfill in Upper Marlboro. Mr. Cartano has in the past expressed interest in beginning with the recovery of corrugated cardboard from new construction waste, with the intention to explore the recovery of other materials as the operation moves forward. Brent Dilts, Executive Vice-President of Brandywine Enterprises, has also received the necessary permits to recover construction waste at his facility in Fairmont Heights. Mr. Dilts expressed interest in the potential recovery of any materials for which a proven market structure exists or is highly likely.
