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

This book was released on 2011-06-28 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is an honor and pleasure for me to write the foreword of this book comprising the of Forest Resources for proceedings of the Fourth Symposium on the Improvement Recyclable Forest Products. The symposium was organized by Dr. Toshihiro Ona, Associate Professor at the Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University, Japan, as part of the "Development of Forest Resources with High Performance for Paper Recycling" research project. This was supported by the Core Research for Evolutional Science and Technology (CREST) team at the Japan Science and Technology Agency Foundation (lST) and by Kyushu University. As a colleague of Dr. Ona, I commend his efforts in organizing the symposium and editing this book. In the forest, there is a multitude of resources, including trees, herbal plants, fruits, fungi, mammals, birds, insects, fishes, reptiles, water, landscapes, and tourist attractions. Nowadays, even the environment is regarded as a kind of forest resource. These resources can provide a diversity of forest products, such as timber for buildings, pulp and paper, charcoal, herbal medicines, wild vegetables, animal protein, edible mushrooms, and nonwoody fibers. From these resources, major forest products are produced using various species of trees. For example, softwood is suitable as building material, while hardwood is suitable for furniture production; pulp and paper are produced from both softwood and hardwood. Therefore, forest locations and forest management methods should vary according to the tree species used for production of different forest products.
