Last decades, wood was promoted as building material. Wood heat treatment by mild pyrolysis has been reported to improve biological durability and dimensional stability of the material and constitutes an attractive « non biocidal » alternative to classical preservation treatments. Previous studies have shown that conferred properties strongly depend on the heat treatment intensity. A quality co...

Research on wood-flour-filled polypropylene has primarily focused on one species of wood flour and one or two broad particle-size distributions. To fully exploit the use of wood flour as a filler, the effects of species and particle size need to be examined. This study focused on the effects of both of these variables on the properties of polypropylene filled with wood flour. To examine the eff...

In 2001, an estimated 433 million new wood pallets were manufactured in the United States, consuming an estimated 6.6 billion board feet (BBF) of hardwood and softwood lumber, cants, and parts (Bejune et al. 2002). Subsequently, another industry has emerged that specializes in the repair and remanufacture of wood pallets. This rise of the wood pallet repair and remanufacture industry is in larg...
