Potentials of Liquefied CCB Treated Waste Wood for Wood Preservation

Bacterial Biodegradation of CCA-Treated Waste Wood

As wood treated with chromated copper arsenate (CCA) is removed from service, methods for eliminating toxic metals from the wood are needed. CCA-tolerant bacteria were evaluated for their ability to modify CCA-treated wood. Aerobic bacteria were isolated from a 20-year-old test plot of CCA-treated stakes. Bacteria selected for their ability to grow on nutrient agar containing CCA components, we...

Potential for Introduction of Preservative Treated Wood in Wood Waste Recycling Streams and its Prevention

Performance Characterization of Coatings on Treated-wood

Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...

Assessing Potential Waste Disposal Impact from Preservative Treated Wood Products

The management of discarded treated wood products upon disposal is one of the many factors that should be considered when evaluating a new wood preservative or when comparing wood preservatives as part of a life cycle assessment. Future environmental ramifications of disposal, as well as regulatory requirements and costs, must be assessed and weighed. This paper presents an overview of the fact...

Physical and Mechanical Properties of Bio-Composites from Wood Particles and Liquefied Wood Resin

Compression molded composites were made from wood particles and a liquefied wood/phenol/formaldehyde co-condensed resin. Based on our previous research, a phenol to wood (P1W) ratio of 2/1 was chosen for this study. The two experimental variables selected were: 1) liquefaction temperature (1500 and 180°C) and 2) cooking method (atmospheric and sealed). Panels were tested in static bending for m...
