Deinking of secondary fibers involves dislodging ink particles from fiber surfaces and separating dispersed ink from fiber suspensions by washing or flotation. Enzymatic approaches involve attacking either the ink or the fiber surfaces. Different enzymes have been used for deinking, including lipases, esterases, pectinases, hemicellulases, cellulases, and ligninolytic enzymes.

Deinking Recycled Paper through Flotation OVERVIEW Recycling paper is a highly important process worldwide. Effective and efficient recycling of wastepaper is crucial to produce high-quality products while minimizing the use of resources (e.g., water, electricity).
Flotation. A prepared pulp suspension was transferred into a 10 L capacity Degussa Flotation Cell (Fig. 1). A calculated amount of calcium chloride (CaCl 2) was dissolved in hot water and poured into the flotation cell to adjust water hardness to 10 dH. Based on dry paper 1 wt.% industrial soap (Olinor-RS 4200 mixed fatty acid) emulsion was also added to the flotation unit before starting the mixer engine.
