Biotechnology In The Pulp And Paper Industry

This collection of comprehensive reviews describes the present knowledge of the enzyme mechanisms involved in the biodegradation of wood and wood components, cellulose, hemicelluloses and lignin by both fungi and bacteria. The extensive knowledge, presented in this volume, was developed in laboratories world-wide over the last few decades and constitutes the foundation for present and future biotechnology in the pulp and paper industry.

Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 million tons of wood pulp is produced worldwide and about 260 million is projected for the year 2010. To be able to cope with increasing demand, an increase in productivity and improved environmental performance is needed as the industry is also under constant pressure to reduce and modify environmental emissions to air and water. The authors give updated information on various biotechnological processes useful in the pulp and paper industry which could help in reducing the environmental pollution problem, in addition to other benefits. Various chapters deal with the latest developments in such areas as raw material preparation, pulping, bleaching, water management, waste treatment and utilization. The book also covers the environmental regulations in various parts of the world as well as the role of biotechnology in reducing environmental problems.

Biotechnology in Pulp and Paper Manufacture: Applications and Fundamental Investigations documents the proceedings of the Fourth International Conference on Biotechnology in the Pulp and Paper Industry held in Raleigh, NC and Myrtle Beach, SC, on 16-19 May 1989. This volume contains 68 selected papers organized into seven parts. Part I deals with cell wall degradation and biopulping. It includes papers such as energy savings in biomechanical pumping, and biological degradation and delignification of rice straw. Part II on the enzyme and fungal treatment of pulps presents studies on the improvement of pulp properties by treatment with enzymes or with whole cells. Part III reports on research on new biological treatments for wastewaters produced by the created by the pulp and paper industry. Part IV discusses the conversion of pulping and papermaking byproducts to more valuable products via fermentation. Parts V and VI are devoted to fundamental studies on lignin biodegradation, and on cellulose and hemicellulose biodegradation, respectively. Part VII focuses on molecular genetics research on lignocelluloses-degrading microorganisms.

This collection of reviews describes current knowledge of the enzyme mechanisms involved in the biodegradation of wood and wood components, cellulose, hemicelluloses and lignin by both fungi and bacteria. The knowledge presented in this volume was developed in laboratories world-wide since the 1970s and constitutes the foundation for present and future biotechnology in the pulp and paper industry.

This book provides the most up-to-date information available on various biotechnological processes useful in the pulp and paper industry. Each of the twenty chapters covers a specific biotechnological process or technique, discussing the advantages, limitations, and future prospects of the most important and popular processes used in the industry. Topics covered include tree improvement, pulping, bleaching, deinking, fiber modification, biosolids management, and biorefining.

This book provides recent developments and future perspectives of pulp and paper processing based on biotechnology to replace conventional environmental unfriendly chemical processes. The use of microorganism and microbial enzymes in various processes such as bleaching, deinking, refining, dissolving pulp, debarking & pitch removal, slime control, wastewater treatment and waste material valorisation are discussed.
