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.

Rezensionen
...an important addition to the information on paper recycling and should find ready acceptance from its intended primary audience. It should also appeal to a wider audience from the stand point of a reference book. - Paper and Board Recycling; McKinney's breadth and depth of recycling knowledge is quite evident...the book should be a valuable addition to the libraries of those new as well as those experienced in recycling. The wealth of information and details in certain chapters should constitute a worthwhile investment. I wholeheartedly recommend the book to all with an interest in paper recycling. - Progress in Paper Recycling; ...it will also prove to be a valuable reference document for those who want, or need to know more about paper recycling. - Chemistry and Industry
