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.

Available in PDF, EPUB and Kindle. Book excerpt: With the exception of a slight hiccup during the height of the recent environmental movement (during the early 1990s), when for a year or two consumers were prepared to pay a price premium for lower quality recycled paper than for the virgin product, the inexorable improvement in the quality demanded of paper products continues. This demand for quality covers not only the aesthetics ofthe product but also its performance. Moreover, it is becoming increasingly the case that papers designed for a particular use must, as it were incidentally, also perform well in alternative applications. An example is that of office and printing papers, which are expected to perform as well in copier machines as in all the various forms of impact and non-impact printers. But even greater demands are made in other product areas, where board designed for dry foods can also be expected to protect moist and fatty materials and be made of 100% recycled fibre. The need to isolate foodstuffs from some of the contaminants that can affect recycled board is a· serious challenge. Thus, papermakers are constantly striving to meet a broadening spectrum of demands on their products; often while accepting declining quality of raw materials. The product design philosophy that has arisen in response to this is increasingly to isolate the bulk of a paper from its uses: to engineer the needed performance characteristics into the paper surfaces while more or less ignoring what happens inside.

Book excerpt: The pulp and paper industry comprises companies that use wood as raw material and produce pulp, paper, board and other cellulose based products. The pulp and paper sector presents one of the energy intensive and highly polluting sectors within the Indian economy and is therefore of particular interest in the context of both local and global environmental discussions. Increases in productivity through the adoption of more efficient and cleaner technologies in the manufacturing sector will be most effective in merging economic, environmental, and social development objectives. Papers are mostly used product starting from writing to packaging. It plays an important role in commercial field as well as in academic field also. Without paper nothing is expressible and reliable, so paper is part and parcel of our life. Adequate amount of raw materials for processing paper and pulp is available. Bamboo is the main raw material for Indian paper industry. New bamboo areas even at high cost are being trapped. Some of the examples of high yield pulping process are mechanical process, semi chemical process, alkaline chemical process, sulfite process, etc. Physical strength properties of paper depend on the quality of raw material, its pulping, bleaching and subsequent paper making processes. Technology has made it easy to process these raw materials in an economic and lucrative way to meet the global demand. Raw materials like, straw, bagasse, wood, bamboo is almost available in most of the places. So it is great opportunity for the entrepreneurs to start up such kind of industry. Paper Industry has tremendously increased in India in the last 20 to 30 yrs. The Paper industry is a priority sector for foreign collaboration and foreign equity participation up to 100% receives automatic approval by Reserve Bank of India. Several fiscal incentives have also been provided to the paper industry, particularly to those mills which are based on non conventional raw material. Some of the fundamentals of the book are bleaching of bamboo cold, high yield semi chemical pulping of mixture of bamboo and mixed hardwoods, sulphate semi chemical process, kraft green liquor semi chemical process, neutral sulphite semi chemical process, thermo mechanical pulps for newsprint, zeta potential concept in paper sizing, sodium carbonate in alkali extraction during bleaching bamboo , maintenance engineering in pulp and paper industry, design and application of refiners in stock preparation, paper machine effluent etc. This book explains about the various raw material, their processing and utilizations and also the possible waste treatment of such paper and pulp making industry. To draw attention for manufacturing quality product with all possible latest technologies is the main purpose of this book. The book is very resourceful for new entrepreneurs, technocrats, existing units and research scholars.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Industrial Design and Waste Management was inspired by the need to have a text that enveloped awareness and solutions to the ongoing issues and concerns of waste generated from industry. The development of science and technology has increased human capacity to extract resources from nature and it is only recently that industries are being held accountable for the detrimental effects the waste they produce has on the environment. Increased governmental research, regulation and corporate accountability are digging up issues pertaining to pollution control and waste treatment and environmental protection. The traditional approach for clinical waste, agricultural waste, industrial waste, and municipal waste are depleting our natural resources. The main objective of this book is to conserve the natural resources by approaching 100 % full utilization of all types of wastes by cradle – to - cradle concepts, using Industrial Ecology methodology documented with case studies. Sustainable development and environmental protection cannot be achieved without establishing the concept of industrial ecology. The main tools necessary for establishing Industrial Ecology and sustainable development will be covered in the book. The concept of "industrial ecology will help the industrial system to be managed and operated more or less like a natural ecosystem hence causing as less damage as possible to the surrounding environment. - Numerous case studies allow the reader to adapt concepts according to personal interest/field - Reveals innovative technologies for the conservation of natural resources - The only book which provides an integrated approach for sustainable development including tools, methodology, and indicators for sustainable development

Available in PDF, EPUB and Kindle. Book excerpt: This multi-authored handbook is a unique cross-industry resource for formulators and compounders, and an invaluable reference for the producers of formulated commodities and industrial minerals. Monographs on each of the common functional industrial mineralsùasbestos, barite, calcium carbonate, diatomite, feldspar, gypsum, hormite, kaolin, mica, nepheline syenite, perlite, pyrophyllite, silica, smectite, talc, vermiculite, wollastonite, and zeoliteùinclude an overview of natural and commercial varieties, market size, and application areas. These are supported by descriptions of mineral structures and the wedding of minerals and chemicals through mineral surface modification. This orientation to the minerals and their uses forms the foundation for chapters where they are presented in the context of the overall technology of various consuming industries. Each of these industry-specific presentations covers both the chemical and mineral raw materials used by the formulator, how these are combined, and relevant test methods. These chapters serve a dual purpose. Each clarifies for technologists the function and value of the mineral constituents of their products. Equally important, they provide a primer on the technology of industries other than their own, so that raw material, formulation, processing and testing considerations can be compared and contrasted.The book concludes with a formulary demonstrating how specific mineral and chemical ingredients are actually compounded in major application areas, and technical data on scores of commercial mineral products.
