The presence of preservatives within construction and demolition of scrap wood, which degrades the quality and limits the potential of this valuable material is discussed. Several different types of preservatives which are used for treating lumber, timber, and plywood include CCA (chromium, copper and arsenic), CBA (copper and boron), and ACZA (copper, zinc and arsenic). Florida Wood Recycling inspects each load based upon visual identification and knowledge concerning the origin of the wood, as it enters the facility. The technologies tested at Florida Wood Recycling include the use of PAN (pyridylazo and naphthol) stain, which when applied to wood, causes a color change if the wood is treated with copper.
