Researchers from Forest Service Report on Findings in Forestry (Mountain Pine Beetle-Killed Lodgepole Pine for the Production of Submicron Lignocellulose Fibrils)

By a News Reporter-Staff News Editor at Agriculture Week -- Investigators publish new report on Forestry. According to news reporting out of Madison, Wisconsin, by VerticalNews editors, research stated, "The elevated levels of tree mortality attributed to mountain pine beetle (MPB) (Dendroctonus ponderosae Hopkins) in western North American forests create forest management challenges. This investigation introduces the production of submicron or nanometer lignocellulose fibrils for value-added materials from the widely available resource represented by dead pines after an outbreak."

Our news journalists obtained a quote from the research from Forest Service, "Lodgepole pine (Pinus contorta Dougl. ex Loud.), trees from two different times since infestation and a noninfested live tree as a control were used for mechanical fibrillation. Fiber deconstruction down to the micro-/nanoscale from infested wood was performed using mechanical fibrillation, without any chemical (pre)treatment. The effects of fibrillation were monitored as a function of processing time, and the respective products were characterized. The changes in fibril morphology, cellulose crystallinity, water retention value, and cellulose adsorption capacity were determined. Interestingly, no significant differences were found between fibrillated samples from the live and the MPB-killed trees."

According to the news editors, the research concluded: "It can be concluded that MPB-killed lodgepole pine is a suitable feedstock for the production of lignocellulose micro-/nanofibrils."
