The North American wood decking market mostly relies on easily treatable Southern yellow pine (SYP), which is being impregnated with micronized copper (MC) wood preservatives since 2006. These formulations are composed of copper (Cu) carbonate particles (CuCO3·Cu(OH)2), with sizes ranging from 1 nm to 250 μm, according to manufacturers. MC-treated SYP wood is protected against decay by solubili...

The aim of the study was to determine occupational exposure in Croatian wood processing industry and forest workers to harmful effects of wood dust on the risk of nose, nasal cavity and lung carcinoma. Mass concentrations of respirable particles and total wood dust were measured at two wood processing plants, three woodwork shops, and one lumbering site, where 225 total wood dust samples and 22...

Wood is a naturally renewable material with both continuous and isolated pore systems. Wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. However, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. Using nano-materials are very easy in the wo...

in this study, the possibility of using canola stem residues for particleboard manufacturing was studied. the ratio of canola straw to the industrial particles was as 25:50, 50:50, 75:25 and 100:00 percents, respectively. urea formaldehyde resin was used as binder at three levels of 8, 10 and 12 percent based on oven dried weight of particles and the press time was at three level of 5, 6 and 7 ...

Exposure to organic dust originating from biofuels can cause adverse health effects. In the present study we have assessed the dustiness in terms of microbial components and particles of various biofuels by using a rotating drum as a dust generator. Microbial components from straw, wood chips, wood pellets and wood briquettes were quantified by several methods. Excellent correlations (r >/= 0.8...

the purpose of this study was to evaluate effects of nano-clay particles and oxidized polypropylene as compatibilizer on the decay resistance of wood plastic composite against coriolus versicolor fungi. in order to provide oxidized polypropylene as compatibilizer, polypropylene was oxidized in the presence of air oxygen in 2 hours by internal mixer. afterwards, wood fibers, polypropylene, nano-...

Thermal treatment of CCA impregnated waste wood is a way to utilize the energy resource of the wood and at the same time to reduce the volume of the waste. An issue of concern in relation to the thermal treatment is As emission to the air. Meanwhile there is still a matter to cope with when methods to avoid As emission are implemented; the residues with increased concentrations of Cu, Cr and As...

Micron-sized particles, prepared from loblolly pine (Pinus taeda L.) wood and bark, were evaluated for use in wood-plastic composites (WPCs). Particles were also prepared from hard (periderm) and soft (obliterated phloem) components in the bark and compared to whole wood (without bark) filler commonly used by the WPC industry. All bark fillers had different thermal degradation profiles and high...

In the present work, the ash transformation and deposition behavior during wheat straw and wood waste combustion were investigated by combustion experiments in an entrained flow reactor. The influence of sewage sludge addition on ash chemistry and deposition tendency was also studied. During combustion wheat straw, fine fly ash particles smaller than 2.5 μm are mainly formed due to vaporization...
