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 Waste Fatty Acid Addition to Black Liquor to Decrease Tall Oil Soap Solubility and Increase Skimming Efficiency in Kraft Mills Pulping Mountain Pine Beetle-infested Wood by : Victor Charles Uloth
Download or read book Waste Fatty Acid Addition to Black Liquor to Decrease Tall Oil Soap Solubility and Increase Skimming Efficiency in Kraft Mills Pulping Mountain Pine Beetle-infested Wood written by Victor Charles Uloth and published by . This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kraft pulping of softwoods converts the free resin and fatty acids and a large percentage of the triglycerides in wood into their sodium salts or soaps. The recovered soap is either burnt in the recovery boiler or converted into a blend of fatty and resin acids and neutrals, known as crude tall oil, through acidulation in a tall oil plant. Recent soap solubility tests and black liquor analyses, using black liquor and soap samples from four BC mills and one Alberta mill pulping very little beetle-killed wood, indicate that tall oil production at mills pulping mountain pine beetle-infested wood could drop substantially due to higher soap solubility in black liquor, a reduced tendency for the soap to "float" off in storage tanks and skimmers, and lower soap acid numbers. This document reports on the investigation of a means to economically increase soap recovery by increasing the fatty acid/resin acid ratio of the product tall oil.--Includes text from document.

Book Synopsis Impact of Mountain Pine Beetle-attacked Lodgepole Pine Logs on Veneer Processing by : Brad Wang
Download or read book Impact of Mountain Pine Beetle-attacked Lodgepole Pine Logs on Veneer Processing written by Brad Wang and published by . This book was released on 2009 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Sustainable Management of Pinus Radiata Plantations by : Donald J. Mead
Download or read book Sustainable Management of Pinus Radiata Plantations written by Donald J. Mead and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Pinus radiata (radiata pine) is a versatile, fast-growing, medium-density softwood, suitable for a wide range of end-uses. Its silviculture is highly developed, and is built on a rm foundation of over a century of research, observation and practice. Radiata pine is often considered a model for growers of other plantation species. This book explores current knowledge of, and experience with radiata pine forest plantation management and examines its long-term sustainability. Radiata pine management needs to integrate the biological aspects of tree-growing, with socio-economics, management objectives, practical considerations and other constraints and opportunities. Although stands of radiata pine may appear to be simple, they are actually quite complex ecosystems because they contain large, long-lived trees that change dramatically over time and interact in changing ways with the environment and with other organisms. The focus of this book is on the principles and practices of growing radiata pine sustainably. It also looks ahead to emerging challenges facing radiata pine plantation management, such as the effects of climate change, new diseases and other threats, and meeting changing product needs and societal demands."--Page 4 of cover.

Book Synopsis Wildlife Ecotoxicology by : John E. Elliott
Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Book Synopsis Growing Plantation Forests by : P. W. West
Download or read book Growing Plantation Forests written by P. W. West and published by Springer Science & Business Media. This book was released on 2013-10-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the scientific principles that are used throughout the world to ensure the rapid, healthy growth of forest plantations. As the population of the world increases so does the amount of wood people use. Large areas of natural forests are being cleared every year and converted to other uses. Almost as large an area of plantation forests is being established annually to replace those lost natural forests. Eventually, plantations will produce a large proportion of the wood used around the world for firewood, building, the manufacture of paper and bioenergy. Forest plantations can also provide various environmental benefits including carbon storage, rehabilitation of degraded land, serving as disposal sites for various forms of industrial or agricultural waste and enhancing biodiversity in regions that have been largely cleared for agriculture. Whatever their motivation, plantation forest growers want their plantations to be healthy and grow rapidly to achieve their purpose as soon as possible. This book discusses how this is done. It is written for a worldwide audience, from forestry professionals and scientists through to small plantation growers, and describes how plantations may be grown responsibly and profitably.
Book Synopsis Sustainable Bioeconomy by : V. Venkatramanan
Download or read book Sustainable Bioeconomy written by V. Venkatramanan and published by Springer Nature. This book was released on 2020-11-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable development is the most important challenge facing humanity in the 21st century. The global economic growth in the recent past has indeed exhibited marked progress in many countries. Nevertheless, the issues of income disparity, poverty, gender gaps, and malnutrition are not uncommon in the global landscape, in spite of the upward growth of the economy and technological advances. This grim picture is further exacerbated by our growing human population, unmindful resource use, ever-increasing consumption trends, and changing climate. In order to protect humanity and preserve the planet, the United Nations issued the “2030 agenda for sustainable development,” which includes but is not limited to sustainable production and consumption practices, e.g. in a sustainable bioeconomy. The hallmark of the sustainable bioeconomy is a paradigm shift from a fossil-fuel-based economy to a biological-based one, which is driven by the virtues of sustainability, efficient utilization of resources, and “circular economy.” As the sustainable bioeconomy is based on the efficient utilization of biological resources and societal transformations, it holds the immense potential to achieve the UN’s Sustainable Development Goals. This book shares valuable insights into the linkages between the sustainable bioeconomy and Sustainable Development Goals, making it an essential read for policymakers, researchers and students of environmental studies.
Book Synopsis Beavers: Boreal Ecosystem Engineers by : Carol A. Johnston
Download or read book Beavers: Boreal Ecosystem Engineers written by Carol A. Johnston and published by Springer. This book was released on 2017-08-28 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridging the fields of ecosystem science and landscape ecology, this book integrates Dr. Carol Johnston's research on beaver ecosystem alteration at Voyageurs National Park. The findings about the vegetation, soils, and chemistry of beaver impoundments synthesized in the text provide a cohesive reference useful to wetland scientists, ecosystems and landscape ecologysts, wildlife managers, and students. The beaver, Castor canadensis, is an ecosystem engineer unequaled in its capacity to alter landscapes through browsing and dam building, whose population recovery has re-established environmental conditions that probably existed for millenia prior to its near extirpation by trapping in the 1800s and 1900s. Beavers continue to regain much of their natural range throughout North America, changing stream and forest ecosystems in ways that may be lauded or vilified. Interest in beavers by ecologists remains keen as new evidence emerges about the ecological, hydrological, and biogeochemical effects of beaver browsing and construction. There is a critical need for ecologists and land managers to understand the potential magnitude, persistence, and ecosystem services of beaver landscape transformation. The 88-year record of beaver landscape occupation and alteration documented by Dr. Carol Johnston and colleagues from aerial photography and field work provides a unique resource toward understanding the ecosystem effects and sustainability of beaver activity.
