Abstract
The paper recycling sector has undergone major changes in
recent years, particularly regarding the quantity and
quality of various materials processed. Material
originating from board grades will increasingly dominate
the recycling market as the use of printing papers
decreases and the amount of non-fiber elements increases.
Users of recycled fiber material have to overcome three
main challenges: price, quality, and availability. This
paper focuses on the quality dilemma in terms of
measurement needs and possibilities from the user
viewpoint. It includes a discussion of the factors
causing deterioration in the quality of paper used for
recycling. Today, the average fiber age is low compared
to what the fibres can tolerate. Therefore, the
characteristic phenomenona in the paper recycling loop
are not caused by the degradation of individual fibers,
but by a blending process in which different fiber grades
and non-fiber components are blended in a non-optimal
way. A novel method iss introduced for evaluating the
quality of recycled fiber material using a new parameter,
the fiber integrity value. The part 2 of this paper will
focus on the application of this new parameter and
demonstrates its correlation with paper properties.
