copper-based preservatives in wood waste streams for recycling. Examples of wood preservatives that contain copper include:
• CCA, copper-chrome-arsenate, which is the most commonly found wood preservative that contains copper, especially in waste wood streams. A wide range of formulations have been used in the past. CCA is now limited to a few industrial uses.
• CCB, copper-chrome-boron. An alternative to arsenic formulations.
• CCP, copper-chrome-phosphate. An alternative to arsenic formulations.
