Relevance of recyclability The term recyclability is related to a specific paper product as already mentioned. Assuming that the grade of paper for recycling and the installed recycling process fit to the paper or board grade to be produced, recycling should be not problematic from the theoretical point of view if each single paper product

Relevance of recyclability
After reading this article you will..
- be able to differentiate between paper categories and how relevant recyclability and deinkability is for them. It should become clear for which product group recyclability tests exist.
