A basic problem with processing biomass in the woods is that the machinery must be matched to the final product. If a logging business owner invests in a machine to produce a specific type of biomass product for a limited market, the opportunity for that logging business owner to diversify products to take advantage of market opportunities may also be limited. When woody biomass material is den...

In Thailand, RSS chamber of community-level rubber cooperatives can be classified into two models: old and new model, named after the years of their establishment. Hot gas as a heat supply from Para-rubber (PR) wood (Hevea brasiliensis) combustion is used for removing moisture from the natural rubber (NR) sheets. Smoke and soot particles from PR wood burning has effected to the quality of the N...

the potential use of nano technology for improving of withdrawal resistance of nail and screw in wood was evaluated. for this, the maintenance strength of nail and screw was measured under dry and wet conditions for poplar wood (populus nigra) coated with common paints in furniture industry and nano-particles. specimens with dimensions of 15×5×5 cm3 (l×r×t) were cut from poplar wood (populus ni...

in this study, the effect of nanoclay particles content on the physical properties and flammability of composite made of high density polyethylene and wood flour was investigated. for this aim, wood flour was combined with hdpe at 50% by weight, and nanoclay was used in 0, 2, 4 and 6%, also 2% of mape as the coupling agent was used in all formulations. the samples were made in injection molding...

This study investigated the effectiveness of heat-treated wood particles for improving the physico-mechanical properties and creep performance of wood/recycled-HDPE composites. The results reveal that the composites with heat-treated wood particles had significantly decreased moisture content, water absorption, and thickness swelling, while no improvements of the flexural properties or the wood...

this research was conducted to investigate the effect of acetylation on weathering resistance of solid wood and particleboard produced from acetylated particles of fagus orientalis. after 12 hours soaking in acetic unhydride, in order to achieve three levels of weight gain, 5, 9 and 16%, acetylated particles of bech wood were heated in oven at 120oc for 30, 90 and 240 minutes, respectively. als...

Background: Residential wood combustion is now recognized as a major particle source in many developed countries, and the number of studies investigating the negative health effects associated with wood smoke exposure is currently increasing. The combustion appliances in use today provide highly variable combustion conditions resulting in large variations in the physicochemical characteristics ...

Carbon particles extracted from sediments collected by box coring from southeastern Lake Michigan were compared with carbon particles extracted from oil, coal, and wood fly ash. Sediments deposited after 1900 contained coal, oil, and wood carbons; older sediments contained only wood carbon.

Residential wood burning is a major source of poorly characterized, deleterious particulate matter, whose composition and toxicity may vary with wood type, burning condition and photochemical age. The causative link between ambient wood particle constituents and observed adverse health effects is currently lacking. Here we investigate the relationship between chemical properties of primary and ...
