ABSTRACT
To date, approximately 30% of fibers are recycled worldwide, with some countries reaching 50%. In the 1980s, the use of recycled fibers increased rapidly In 1986 the overall waste paper use (raw material input per production output) in Western Europe was only about 35%, which corresponded to about 30% furnish share in the pulp mixture. Global use at the end of the 1980s was approximately 75 million tonnes of recycled fiber per year, and it has been estimated that by the year 2000 this could increase to 130 million tonnes per year (Jaakko Pöyry, 1990).
