Waste Paper Recovery

Public concern for the conservation of natural resources and a general awareness of the environmental consequences of waste disposal is reflected in current legislation aimed at reducing waste. Recycling is commonly cited as one of the preferred methods of waste reduction and this book summarizes a recent study of paper recycling in Europe, which investigated the entire production and disposal process using a life-cycle methodology. The results of the study underline the economic and environmental advantages of paper recycling, but more controversially, they also show how, under certain conditions, the renewable character and the high energy content of paper seem to make energy recovery more attractive than recycling.

Vast quantities of used paper are discarded every day despite the technology existing to recover and recycle the material. Throughout the world, a number of legislative and industry-led initiatives, aimed at value recovery from paper collected for recycling, have been introduced with a view to increasing public awareness of paper recycling and creating a sustainable environment.This book presents the proceedings of an international Symposium organised by the Concrete Technology Unit, University of Dundee, whcih brings together some of the worlds leading experts in the field of paper recovery and recycling.

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 covers the technology of the recovery of secondary fibre for its use in paper and board manufacture. The editor, who has had substantial practical experience of designing and commissioning paper recycling plants all over the world, leads a team of experts who discuss subjects including sourcing, characterisation, mechanical handling and preparation and de-inking.
