The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great number of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited and therefore some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production and as the cost of waste disposal continues to increase, this issue is becoming more and more severe.
