United States Environmental Protection Agency National Risk Management Research Laboratory Cincinnati, OH 45268 Research and Development EPA/600/SR-96/066 June 1996 EPA Project Summary Characterization of Manufacturing Processes and Emissions and Pollution Prevention Options for the Composite Wood Panel Industry Cybele Martin and Coleen Northeim The report summarizes information gathered on emissions from the com- posite wood industry (also called the plywood and particleboard industry) and potential pollution prevention op- tions. Information was gathered during a literature search that included trade association publications, journal ar- ticles, symposium presentations, and university research. Little information exists in the litera- ture pertaining to pollution prevention. Most available literature focuses on ways to reduce raw material consump- tion and improve manufacturing pro- cesses. However, in many instances, these reductions and improvements lead to pollution prevention benefits. Some of these potential pollution pre- vention options presented in the report include: conveyor belt drying, low tem- perature drying, high moisture bond- ing adhesives, foam extrusion, and vari- able glue application rate. Other pollu- tion prevention options presented in the report include alternative fiber sources (e.g., agricultural fiber and re- cycled wood waste) and naturally de- rived adhesives. These options are pre- sented as resources that are abundant and renewable. Little emissions data exist in the literature to include with these options. This Project Summary was developed by the National Risk Management Re- search Laboratory's Air Pollution Pre- vention and Control Division, Research Triangle Park, NC, to announce key findings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back). Overview The composite wood manufacturing in- dustry (initially called the plywood and par- ticleboard industry) was included in EPA's initial list of air toxics source categories under Section 112 of the Clean Air Act Amendments of 1990. The industry was defined by the EPA as "...any facility en- gaged in the manufacturing of plywood and/or particleboard, including, but not lim- ited to, manufacturing of chip waferboard, strandboard, hardboard/cellulosic fiber- board, oriented strandboard, hardwood ply- wood, medium density fiberboard, soft- wood plywood, or any other wood com- posite product manufactured using binder". EPA's Office of Air Quality Planning and Standards (OAQPS) will be writing maxi- mum achievable control technology (MACT) standards for Hazardous Air Pol- lutants (HAPs) as they apply to the com- posite wood panel manufacturing indus- try; the MACT regulations for this industry are scheduled to be proposed in 1999. The Pollution Prevention Act of 1990 requires EPA to review regulations of the Agency prior to their proposal to deter- mine the effect of regulations on source reduction. In response to this charge, EPA has established the Source Reduction Review Project (SRRP), the goals of which are to ensure that source reduction mea- sures and multimedia issues are consid- ered during the earliest stages of devel- opment of regulations under the Clean Air Act, Clean Water Act, and Resource Con- ------- servation and Recovery Act. The SRRP is focused on 17 industrial categories that will be affected by the above regulations; the composite wood panel manufacturing industry was selected as one of the 17 categories. EPA's National Risk Management Re- search Laboratory (NRMRL)/Air Pollution Prevention and Control Division (APPCD) worked in conjunction with OAQPS on implementing the SRRP for the composite wood panel manufacturing industry. As part of this effort, Research Triangle Insti- tute was contracted to characterize emis- sions from manufacturing processes and to identify potential pollution prevention opportunities for reducing them. The report summarizes information gath- ered on emissions from the composite wood industry and potential pollution pre- vention options. The information was gath- ered during a literature search that in- cluded trade association publications, jour- nal articles, symposium presentations, and university research. Little information exists in the literature pertaining to pollution prevention. Most available literature focuses on ways to reduce raw material consumption and im- prove manufacturing processes. However, in many instances, these reductions and improvements lead to pollution prevention benefits. Some of these potential pollution prevention options are presented in this report and include: conveyor belt drying, low temperature drying, high moisture bonding adhesives, foam extrusion, and variable glue application rate. Other pollu- tion prevention options presented in the report include alternative fiber sources (e.g., agricultural fiber and recycled wood waste) and naturally derived adhesives. These options are presented as resources that are abundant and renewable. Little emissions data exist in the literature to include with these options. ------- C. Martin and C.
