Product Description:
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.
• Copper organics, these could contain the fungicides propiconazole and or tebuconazole or quaternary ammonium compounds. Other azoles are in development. These types of wood preservatives are becoming increasingly popular after the restrictions on the use of CCA were published.
