Clean Method for Stickies Control with StickAway Enzyme in ONP Pulps

Abstract:

Recovery and use of secondary fiber for paper production is increasing all over the word. In recovered paper recycling, stickies are the most detrimental among the contaminants, affecting both the process efficiency and the quality of the final product. In this study, StickAway enzyme was used to treat the old newspaper(ONP) pulps. The effect of enzymatic treatment on the macro and micro-stickies, the drainage property, as well as the formation of paper products were investigated. After treatment of samples with 3LU/g (o.d pulp) doses of enzymatic for 1.5 h, it was found that 14.6% of the micro-stickies could be removed. The cationic demand, turbidity value and particle size were decreased 7.23%, 14.4% and 6.02% respectively compared the control sample. Furthermore, enzymatic treatment also improved the drainage properties of pulp slurry and the formation of paper products. Results confirmed that under the optimal conditions, the StickAway enzyme show the excellent performance in the treatment of the stickies of recovered pulps.
