Efficiency and sustainability the two words that continue to dominate current thinking FOREWORD I do hope you will find the excellent articles brought together here from all areas of the paper manufacturing process to be an interesting useful and thought provoking read. I extend my grateful thanks to all those who have contributed this year being able to draw upon the input and unique knowledge of so many technical experts allows us to once again present this unique platform of communication for this industry. With efficiency and sustainability being the two words that continue to dominate current thinking it is unsurprising to find so many of the editorials herein exploring these topics from different areas of the manufacturing and supply process. It has been another hugely exciting year for us with this the International Edition of World Pulp Paper as well as our stand-alone Chinese Edition published in Mandarin continuing to flourish the latter having truly established itself as a must read in the region. A number of readers have recently asked whether we could perhaps explore the possibilities of an additional publication to focus upon the growing Biomass and Bioenergy sectors. In response the pilot issue of World Biomass was duly published in August last year to a very warm worldwide reception. World Biomass has therefore joined World Pulp Paper as an annually-published title in our steadily growing portfolio. Meanwhile I wish you every success in the months ahead and hope that you will thoroughly enjoy this edition of World Pulp Paper.
