Book Synopsis Assessment of the Economic (pulping and Pulp Quality) Effects of Increased Lodgepole Pine in SPF Chip Mixtures by : Barbara Dalpke
Download or read book Assessment of the Economic (pulping and Pulp Quality) Effects of Increased Lodgepole Pine in SPF Chip Mixtures written by Barbara Dalpke and published by . This book was released on 2007 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. It examines British Columbia's market kraft and mechanical pulps, which are produced from interior spruce, pine and fir (SPF) and are significant for the province's economy. The chips used to produce SPF pulp are a residual material from lumber operations and are traditionally composed of approximately 30% spruce, 65% lodgepole pine and 5% subalpine fir. However, due to the mountain pine beetle epidemic in the province, this balance is subjected to climb to a pine content of 80% to 90% as salvage harvesting of attacked and dead lodgepole pine stands increases. This study quantitatively and qualitatively defines pulp quality changes with changing chip mixture in order to increase understanding of problems that can be anticipated with changing chip quality needs.--Includes text from Government of Canada publications site and from document.

Available in PDF, EPUB and Kindle. Book excerpt: This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle (MPB) epidemic. It presents the results of pilot plant Kraft and mechanical pulping trials that were conducted to determine the influence of time-since-death (TSD) of (MPB)-killed lodgepole pine on pulping and pulp quality. Samples included trees of red, grey and late grey attack stages as well as unattacked trees; sample sites were established in three different biogeoclimatic subzones in British Columbia in order to account for natural variability. Prior to pulping, samples were tested for wood and fibre properties as well as chip quality. Kraft and thermomechanical (TMP) pulping parameters were monitored, pulp quality was determined, and sheet structure was evaluated by scanning electron microscopy.--Includes text from document.

Book Synopsis Cost Implications for Thermomechanical Pulping and Brightening of Blue-stained Chips by : Thomas Qiuxiong Hu
Download or read book Cost Implications for Thermomechanical Pulping and Brightening of Blue-stained Chips written by Thomas Qiuxiong Hu and published by . This book was released on 2007 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lodgepole pine (Pinus contorta Dougl.) forests make up approximately 35% of British Columbia's forested land base and accounty for 25% of the province's total volume harvested. Mountain pine beetle (Dendroctonus ponderosae Hopk.) is currently B. C.'s most devastating forest insect and it has wrought more destruction in mature lodgepole pine forests than any other forest insect. In an attempt to deal with the pine beetle infestation, an accelerated harvesting of pine stands damaged with this insect has been ordered by B. C. Ministry of Forests throughout the north central part of the province. Mature lodgepole pine trees attacked by the pine beetle are afflicted through the introduction of Ophiostoma piliferum, a fungus that causes blue stain in the sapwood. This preliminary study was undertaken to quantify the costs associated with thermechanical and chemithermomechanical pulping and brightening the mechanical pulps produced from blue-stained and sound lodgepole pine chips.--Document.
Book Synopsis Quantifying the Effect of Extractives from Mountain Pine Beetle-attacked Lodgepole Pine for Pulp and Papermaking by : Paul Alexandre Bicho
Download or read book Quantifying the Effect of Extractives from Mountain Pine Beetle-attacked Lodgepole Pine for Pulp and Papermaking written by Paul Alexandre Bicho and published by . This book was released on 2008 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Recent Advancement in White Biotechnology Through Fungi by : Ajar Nath Yadav
Download or read book Recent Advancement in White Biotechnology Through Fungi written by Ajar Nath Yadav and published by Springer. This book was released on 2020-10-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade considerable progress has been made in white biotechnology research and further major scientific and technological breakthroughs are expected in the future. The first large-scale industrial applications of modern biotechnology have been in the areas of food and animal feed production (agricultural/green biotechnology) and in pharmaceuticals (medical/red biotechnology). In contrast, the productions of bioactive compounds through fermentation or enzymatic conversion are known as industrial or white biotchnology. The fungi are ubiquitous in nature and have been sorted out from different habitats, including extreme environments (high temperature, low temperature, salinity and pH); and associated with plants (Epiphytic, Endophytic and Rhizospheric). The fungal strains are beneficial as well as harmful for human beings. The beneficial fungal strains may play important roles in the agricultural, industrial, and medical sectors. The fungal strains and its product (enzymes, bioactive compounds, and secondary metabolites) are very useful for industry (e.g., the discovery of penicillin from Penicillium chrysogenum). This discovery was a milestone in the development of white biotechnology as the industrial production of penicillin and antibiotics using fungi moved industrial biotechnology into the modern era, transforming it into a global industrial technology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors providing both high value nutraceutical and pharmaceutical products. The fungal strains and bioactive compounds also play an important role in environmental cleaning. This volume covers the latest research developments related to value-added products in white biotechnology through fungi.
