Available in PDF, EPUB and Kindle. Book excerpt: Paper recycling in an increasingly environmentally conscious world is gaining importance. Increased recycling activities are being driven by robust overseas markets as well as domestic demand. Recycled fibers play a very important role today in the global paper industry as a substitute for virgin pulps. Paper recovery rates continue to increase year after year Recycling technologies have been improved in recent years by advances in pulping, flotation deinking and cleaning/screening, resulting in the quality of paper made from secondary fibres approaching that of virgin paper. The process is a lot more eco-friendly than the virgin-papermaking process, using less energy and natural resources, produce less solid waste and fewer atmospheric emissions, and helps to preserve natural resources and landfill space. Currently more than half of the paper is produced from recovered papers. Most of them are used to produce brown grades paper and board but for the last two decades, there is a substantial increase in the use of recovered papers to produce, through deinking, white grades such as newsprint, tissue, market pulp. By using recycled paper, companies can take a significant step toward reducing their overall environmental impacts. This study deals with the scientific and technical advances in recycling and deinking including new developments. Covers in great depth all the aspects of recycling technologies Covers the latest science and technology in recycling Provides up-to-date, authoritative information and cites many mills experiences and pertinent research Includes the use of biotech methods for deinking, refining. and improving drainage

Download or read book Morphology of Wood Pulp Fiber from Softwoods and Influence on Paper Strength written by Richard A. Horn and published by . This book was released on 1974 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve full utilization of each harvested tree, interest centers on use of all of the tree components. The objective of the study is to determine the influence of the morphological characteristics of pulp fiber from 12 western U.S. softwood species, representative of a wide range of fiber. The effect of the morphology of the wood pulp fiber as distinguished from that of the wood fiber is emphasized because differences in performance of fiber-based products are traced to the pulp fiber. Interrelationships of fiber morphology and pulp sheet properties are discussed. The results indicate that it is not possible to fully characterize the performance of a pulp by a single morphological characteristic and that the morphological characteristics significantly influence strength properties of sheets.

Book excerpt: Papers on recycling have been a part of Conference Proceedings and Tappi Journal for decades. In just the past nine years, several hundred papers ona spects of recycling ahve been presented at conferences and published in the journal. To use htis collected body of knowledge, this book was created by reviewing and selecting the best of the appers on recycling presented at TAPPI Conference or published in Tappi Journal during the past nine years. The issues of collected wasste paper quality, deinking of newsprint, and the challenges of recycled paper production are addressed in these pages. Solid waste, mandatory collection, quality control, "stickies" contamination, and more are all a part of this collection.

Available in PDF, EPUB and Kindle. Book excerpt: Recycling and Deinking of Recovered Paper, Second Edition covers recent advances in recycling technologies. This second edition examines this new process, which is more eco-friendly than the virgin-papermaking process, and which uses less energy and natural resources, produces less solid waste and fewer atmospheric emissions, and helps to preserve natural resources and landfill space. In addition, the most recent information about the recycling of fibers into various grades of paper and board, the control of stickies, and the effects of recycled fiber on paper machines are also covered. Recycling technologies have been improved in recent years due to advances in pulping, flotation deinking, and cleaning/screening, resulting in the quality of paper made from secondary fibers remarkably approaching that of virgin paper. Covers all aspects of recycling technologies in great depth Offers up-to-date authoritative information and cites many mills experiences and pertinent research Examines the use of biotech methods for deinking, refining, improving drainage, and stickies control Includes new case studies on paper recycling

This book was released on 2004-02-09 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pulp and paper industry continues to expand at a phenomenal rate and it has an important role to play on the Indian economy. This imposes a difficult problem of selection. Since the amount of material that can be included in a single volume is obviously limited. Careful thought has been given to the selection with the purpose of presenting that material which will be of the greatest interest to the greatest numbers. Paper is one of the major components of urban solid waste (household and commercial waste) and has a potential resource value when collected and reused. Recycling of the waste paper has been a practice that has prevailed in the paper industry since its inception and therefore continues. The preservation of forests and increasing environmental awareness has focussed research on exploration of new fibrous resources and less toxic pulping and bleaching processes. The use of non woody already account for 9.1% of total world papermaking capacity. A variety of non woody plant fibres are used for papermaking. Paper converting refers to the processing of raw paper to produce improved grade of paper or a finished paper article. There are two types of paper converting; wet converting and dry converting. The Indian paper industry has close linkages with economic growth as higher industrial output leads to increased demand for industrial paper for packaging, increased marketing spend benefits the newsprint and value added segments, and increased education and office activities increase demand for writing and printing paper. It is estimated that there is an economic growth of 8.5% for India which will benefit the demand for paper. This book basically comprises of bio refiner mechanical pulping of bast type fibres, use of trichromatic colourimetery for measurement of brightness and yellowness of bleached pulps, finishing and converting, coating equipment, chemical and additives in papermaking, mixed pulping of jute stick and other agricultural residues etc. This book also comprises of the list of manufacturers, suppliers of plant & machinery and allied products, list of manufacturers and suppliers of raw materials, imported pulp manufacturers & suppliers imported pulp, Indian agents for imported pulp etc. This informative book will be helpful for paper technologist, paper chemists and scientists related to paper field.
