Recycling and Deinking of Recovered Paper, Second Edition, covers recent advances in recycling technologies. 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 fibres approaching that of virgin paper. This second edition will examine this new process which is more eco-friendly than the virgin-papermaking process, which uses less energy and natural resources, produce less solid waste and fewer atmospheric emissions, and helps to preserve natural resources and landfill space. 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, paper recycling and the business's impact on new developments will be also addressed.

1. Introduction 2. Legislation for use of recycled paper 3. Collection systems and sorting 4. Process steps in recycled fibre processing 5. System and process design for different paper and board grades 6. Effects of recycling on pulp quality 7. Chemicals used in deinking systems and their function 8. Enzymatic deinking 9. Bleaching of deinked pulp 10. Refining of recycled fibres 11. Improvement of drainability of recycled fibers 12. Effects of recycled fibre on paper machines 13. Control of stickies 14. Water Reuse, Wastewater Treatment and Closed-Cycle Operation 15. Case studies on Paper recycling 16. Environmental aspects 17. End use of Recovered Paper other than Papermaking 18. Future of deinking

Dr. Pratima Bajpai is currently working as a Consultant in the field of Paper and Pulp.
