Abstract—Waste paper recycling has increased dramatically in recent times, and will continue to do so in the foreseeable future. Ink removal constitutes one barrier to converting this raw material into quality products. Enzymatic deinking represents one approach to lowering this barrier. Enzymatic processing, offers potential opportunities for changing the pulp & paper industry towards more environmentally friendly and efficient operations compared to conventional methods. The study addresses two (2) commercial enzymes (lipase and esterase) for their efficiency and suitability used in deinking of laser-printed paper and how their sequences can facilitate the best result of the deinking process. Results revealed that both are with great potential with lipase is superior to the esterase in the deinking of laser printed paper.

Index Terms—laser-printed paper, lipase, esterase, enzymatic deinking
