Gibson Auditions Torrefied Maple for Fretboards | Woodworking ...26 Nov 2011 ... Gibson CEO Henry Juskiewicz told WLPN-FM that he is anxious to see customers' reaction to the new composite wood. It is being used as a substitute following the raid of Gibson factories in August in which federal agents confiscated more than 10,000 fingerboards made from allegedly illegal Indian rosewood. Two comments posted this week on Gibson's website provide some insight to what is on the mind of Gibson customers about the use of torrefied maple.

Applied Biorefinery Sciences - Hydro-TorrefactionThe environment is not sufficient to break down the cellulose matrix, so the residual biomass, although darker in color, remains structurally intact. Known as hydro-torrefied biomass, the processed material is less reactive to water, and therefore improved for manufacturing traditional wood products such as fuel pellets, pulp and paper, fiberboard, or composites, as well as new technology wood products. Compared to wood chips, hydro-torrefied wood chips have: Darker color

A review of wood thermal pretreatments to improve wood composite ...27 Jul 2013 ... 2011); the production of wood composites requires processes such as chipping, reduction of particle size, and drying (Sharp 1969;. Kollmann et al. 1975; Maloney 1993; Bowyer et al. 2007; Klyosov 2007; Clemons. 2010). Gasification, combustion, and pyrolysis of wood, as well as the production of pellets, have shown that torrefaction after reducing particle size and drying is a promising pretreatment operation (e.g., less oxygen/carbon on biomass after torrefaction ...

Wood composites | Treesearch - Forest Service - USDAA composite can be defined as two or more elements held together by a matrix. By this definition, what we call solid wood is a composite. Solid wood is a three-dimensional composite composed of cellulose, hemicelluloses and lignin (with smaller amounts of inorganics and extractives), held together by a lignin matrix. The advantages of developing wood composites are (1) to use smaller trees, (2) to use waste wood from other processing, (3) to remove defects, (4) to create more ...

Effect of temperature during wood torrefaction on ... - ResearchGate20 Jun 2014 ... wood torrefaction. Ponderosa pine. wood pellets. wood composites. a b s t r a c t. Torrefaction enhances physical properties of lignocellulosic biomass and improves its grindability. Energy densification, via fuel pellets production, is one of the most promising uses of torrefaction. Lignin con- tributes to self-bonding of wood particles during pelletization. In biomass thermal pretreatment, part of lignin (in the form of lignin liquid intermediates LLI) migrates from the cell ...

Torrefied Wood | New Biomass Holding LLCNew Biomass is the industry leader in torrefied wood pellet manufacturing. We are the world's largest provider of torrefied wood pellets, which are an immediate and practical replacement for coal. What is torrefied wood? torrefied wood is a renewable, carbon-neutral energy source that is more energy dense than wood and almost as dense as coal. torrefied wood is created from biomass material that goes through a process called torrefaction. What is Torrefaction? Torrefaction is the ...

Torrefied Wood Pellets | New Biomass Holding LLCtorrefied wood brings great value to applications beyond energy as well. torrefied wood is an excellent candidate for plastics and composite materials because it is hydrophobic, durable, can withstand processing at higher temperatures and is lighter weight than regular wood flour. torrefied wood is beneficial as a soil amendment, improving soil stability and crop yields and reducing irrigation needs, and as a feedstock for gasification, resulting in much cleaner syngas compared to ...

Torrefied biomass-polypropylene composites - Chiou - 2014 ...4 Nov 2014 ... ABSTRACT. torrefied almond shells and wood chips were incorporated into polypropylene as fillers to produce torrefied biomass-polymer composites. The composites were prepared by extrusion and injection molding. Response surface methodology was used to examine the effects of filler concentration, filler size, and lignin factor (relative lignin to cellulose concentration) on the material properties of the composites. The heat distortion temperatures, thermal ...
