"This report addresses the impact of mountain pine beetle infestation on extractives in pulp and paper mills and their impact on process operation. The main concerns addressed include: extractives in pulp, pitch control, friction properties of paper, effluent treatment, and soap separation in the draft chemical recovery system."--Document.

Download Quantifying the Effect of Extractives from Mountain Pine Beetle-attacked Lodgepole Pine for Pulp and Papermaking Book in PDF, ePub and Kindle
The pulping of mountain pine beetle-killed wood can impact tall oil recovery, and severe foaming events exist. These effects may be related to changes in the levels and profiles of extractives in beetle-killed wood. This report summarizes existing knowledge regarding the influence of mountain pine beetle attack on extractives. It expands on this knowledge by using PLS-DA modeling to follow changes in extractives profiles with unattacked-green, red and grey stage woods. Result show that red stage pine has lower levels of glycerides and pimaric acid, but higher levels of sterols, than unattacked green wood. Grey stage woods have extractives profiles that are comparable to unattacked wood, likely due to the biodegradation of glycerides or to abiotic effects. While extractives are implicated in the foaming tendency of TMP pressates and black liquors from beetle-infested wood, other factors related to wood chemistry are just as important when addressing the foaming issue.

Download Impact of Mountain Pine Beetle-attacked Lodgepole Pine Logs on Veneer Processing Book in PDF, ePub and Kindle
The issue of how to maximize the value recovery from beetle-attacked pine wood is critical to the wood panel industry in British Columbia. This paper discusses the pilot plant tests and mill trials that were conducted to quantify the impact of using mountain pine beetle (MPB)-attacked lodgepole pine (Pinus contorta Douglas) wood on green veneer processing to determine of it makes economic sense to sort and process MPB logs separately from normal logs of SPF (spruce-lodgepole pine-alpine fir) mix for plywood manufacturing.--Includes text from document.

Download Remedial Treatment of Lodgepole Pine Infested with Mountain Pine Beetle Book in PDF, ePub and Kindle
Lindane is registered for remedial control of bark beetles; however, forestry uses are controversial and alternative chemicals are needed. Chlorpyrifos (Dursban 4E), carbaryl (Sevimol 4), and fenitrothion (Sumithion 8E) at 1, 2, and 4 pct active ingredient, and lindane at the registered dosage of 0.6 pct were sprayed on lodgepole pine (Pinus contorts Dougl. var. latvolia Engelm.) bolts infested with mountain pine beetles (Dendroclonus ponderosae Hopkins) in Colorado. Mean survival ratios (n=10) of the proportions of beetles emerging from treated bolts to the proportion emerging from control bolts indicated that chlorpyrifos and fenitrotkion at 2 and 4 pct were about as effective as lindane in reducing emergence.
