8 The European version of the Guide to an Optimum Recyclability of Printed Graphic Paper was approved by several European Associations in March INGEDE is signatory of the European Declaration on Paper Recycling in its new version of 26 Orientation values for recyclability are adopted on German level Deinkability Scores are in development 3 Work for Improving the Recyclability of Printed Products No.: 8

9 Introduction to maintain the achieved standard, it is also necessary that everyone involved in the paper chain including parties placing the order and designers of print products give due consideration to the requirements of recycling. Soluble and Redispersible Components The requirement therefore is that recovered paper should contain as few components as possible, which dissolve or disperse in weakly alkaline medium and form sticky residues or cause discolorations. Recyclability Assessment Therefore it is necessary that all parties involved evaluate their products as to good recyclability if major changes are made at materials and processes. Abstract from the Guide to an Optimum Recyclability of Printed Graphic Paper No.: 9

10 Design, manufacturing and converting of paper based products in such a way as to enable a high quality recycling of fibres and other materials in a manufacturing process in compliance where appropriate with current standards in the Community. European Declaration on Paper Recycling Definition of Recyclability No.: 1

11 For good recyclability, paper products have to be: Repulpable important for all types of paper products Deinkable important for all white grades and additionally Adhesives have to be removable important for all types of paper products Challenges of Paper Recycling No.: 11

24 Recycling of paper and board products will still further increase in Europe For graphic paper products a test method for the evaluation of the deinkability is developed The deinkability score makes it much easier to communicate deinkability results even with non-experts Recycling friendly print products can be manufactured although the spectrum of results is large Conversation and cooperation between the participants of the paper chain has to be improved further INGEDE offers a platform for exchanges which strengthens the network between the partners of the graphic paper chain Conclusions No.: 24
