Additives – Recycled Fibre Additives play an important role in processing of paper for recycling. Without additives removal of ink during stock preparation processes is almost impossible. In this section, the major applications in the fields of deinking, bleaching, process water treatment and sticky control are discussed. An innovative field with growing industrial applications is the use
