| Sumario: | In This Study,Effect of Enzymatic Deinking on Mechanical Strength of old newspaper was investigated .The protocol for the enzymatic treatment of old newspaper on a laboratory scale using cellulase and combination of callulase:lipase was developed as an effective method for paper recycling.
The deinking conditions of pulping consistency of 4% with the pulping time of 2/5 min.temperature 20 and 50 C.at neutral PH.
The study focused on analyzing the effects of enzyme treatment on mechanical strength of old newspaper.
The results showed that enzymatic treatment increases the mechanical strengths of the treated pulp compared to the control pulp.Also, the effect of combination of cellulase and lipase on improvement of mechanical strengths of pulp is more than cellulase treatment alone. |
