DOWNLOAD EBOOKPulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 millions tons of wood pulp is produced worldwide and about 260 millions is projected for 2010. To cope with the increasing demand, an increase in production and improved environmental performance is needed as the industry is under constant pressure to reduce environmental emissions to air and water. This book gives updated information on environmentally benign approaches for pulp bleaching, which can help solve the problems associated with conventional bleaching technologies.* Main focus is on the environmentally friendly technologies that can help solve some of the problems associated with conventional bleaching technologies* Information given is up-to-date, authoritative and cites the experiences of many mills and pertinent research, which is of interest to those working in the industry or intending to do so* Covers in great depth all the aspects of various bleaching processes including environmental issues

DOWNLOAD EBOOKThis book describes the most effective application of chemicals in bleaching. It starts with a brief overview of the history of bleaching and then focuses on recent developments. The ban of chlorine from bleaching pulp has shifted bleaching to environmentally sound procedures. Elementary Chlorine Free bleaching (ECF bleaching) and Totally Chlorine Free bleaching (TCF bleaching) are explained. The potential of different bleaching chemicals is exemplified in detail with a special focus on what to do and what to avoid. Very recent knowledge about the sources of yellowing is utilized to explain the ideal strategy for the removal of chromophores and their precursors. Emphasis is placed on applicable bleaching, in clear contrast to sophisticated, complicated or simply expensive pseudo modern bleaching. The target of this book is to explain the potential and the limitations of different chemicals and to demonstrate the necessity of comprehensive solutions for an environmentally sound use of the raw material wood, of chemicals, and of water in the production of pulp with top quality and yield. This book should educate students in the art of bleaching, assist mill personal in their continuous effort for process optimization, help research and technology managers to successfully select their targets, and be on hand as reference of the most recent bleaching technology.

DOWNLOAD EBOOKThis book covers bleach plant effluents, that most polluting effluent from the pulp and paper industry. Disappearance of benthic invertebrates, a high incidence of fish diseases, and mutagenic effects on the aquatic fauna are some of the consequences of the disposal of bleach effluents into surface waters. This book describes environmental impact of bleach plant effluents, environmental regulations, and measures to reduce the pollution load by internal process modification and external treatment of bleach plant effluents.

DOWNLOAD EBOOKPulp 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.

DOWNLOAD EBOOKIn recent years, there have been emerging concerns regarding the fate and effects of pulp and paper mill effluents on the environment. Countries throughout the world are focusing attention on the implementation of regulatory and monitoring programs. In response, industry has begun to implement a variety of process and treatment technologies designed to minimize or eliminate the potential impacts. Environmental Fate and Effects of Pulp and Paper Mill Effluents explores the most active and critical current research and experimentation from around the world. This comprehensive overview examines the identity and origin of chemicals in pulp mill effluents, environmental fate of chemicals from pulp and paper mills, bioaccumulation of substances from pulp mills to fish and wildlife, field and laboratory studies of biochemical and whole organism responses associated with pulp and paper effluents, integrated monitoring and future research, and policy directions of this rapidly evolving field. Written by prominent scientists from around the world with contributions from industry, government, and academia, this important new book provides a balanced global perspective of the recent scientific findings and the challenges being faced in the immediate future.
