Remediation of Pentachlorophenol (PCP) in Biodiesel versus Diesel Carriers
2011 - IRG/WP 11-50279
Biodiesel is believed to be more environmentally friendly than petroleum based diesel when used as a carrier for impregnation of PCP into wood products for protecting wood from decay. A six month study was conducted to evaluate the remediation of PCP in biodiesel versus diesel in soil. Different percentages of biodiesel, diesel and PCP were mixed with clean soil from a forested site and tested. Sa...

Removal of nano- and micronized-copper from treated wood by chelating agents
2013 - IRG/WP 13-50294
Micronized and nano-copper (Cu)-based and arsenic and chromium-free systems have received much attention for wood protection in recent years. Because they have different fixation, and micro-distribution properties, such copper systems may be more or less subject to release using known remediation methods than soluble forms of Cu. This study evaluated Cu recovery from wood treated with micronized- ...

On-site remediation treatments for framing timber in leaky buildings
2014 - IRG/WP 14-20549
Weathertightness failures in New Zealand buildings due to the combined effects of cladding choices, design and construction faults and the use of untreated framing timber has led to the so called ‘leaky building syndrome’. The latest estimated cost of the leaky building crisis in New Zealand is about NZ$11 billion. This research was conducted to provide a better understanding of the option...

Properties of Wood Plastic Composites Made of Recycled HDPE and Remediated Wood Flour from CCA/CCB Treated Wood Removed from Service
2016 - IRG/WP 16-40747
Chromated copper arsenate (CCA) and copper, chromium and boron (CCB) have been widely used in pressure treated wood as a heavy duty preservative to protect wood against insects and fungi for more than 60 years. Although many attempts have been done to solve the problems related to out-service treated wood, the problem still remains. Only a few studies were done to utilize the out-of service treate...

Bacterial Degradation of Pentachlorophenol Indicated in Groundwater Undergoing Long Term In-Situ Remediation
2016 - IRG/WP 16-50318
Pentachlorophenol (PCP, Penta) is a worldwide soil and water contaminant. The pervasive use of PCP as a fungicide, herbicide, pesticide, and as preservative for wood products has led to its global distribution. It is a highly effective preventative measure for most invasive insects, bacteria, fungi, and molds, as well as an excellent wood protection treatment. This study examined a known PCP conta...
