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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
