Description:
This guide provides an overview of the wood preserving industry and presents options for minimizing waste generation through source,reduction and recycling. reatment with both oilborne and waterborne preservatives is discussed in this guide. owever, because in the United States, the majority of wood is treated with chromated copper arsenate, the guide focuses on waterborne preservatives. rocess wastewater surface runoff water, and sludge.are possible sources of contamination in the wood preserving industry, although in waterborne processes the majority of wastewater is reused. rocess wastewater includes water from conditioning, kiln drying, treated wood washing, accumulations in doors or retort sumps, preservative formulation recovery, and rinsing. urface runoff water flows from nonprocess areas, such as treated wood storage yards. ludge consists of oil-water emulsions, water/debris mixtures, and wood debris. educing the amount of this waste will benefit both the wood preserving industry and the environment.
