Microbial Deinking of Printed Paper
In this study we report the deinking of printed paper using microorganisms isolated from oil contaminated soil. The microorganisms producing lipase and esterase enzymes were screened using tributyrin agar. Deinking of the pulp was carried out using screened microorganisms and the preliminary identification of the microorganism that showed effective deinking was carried out by biochemical tests ...
متن کاملIPST Technical Paper Series Number 867 Flotation Deinking of Old Newsprint Using Poly(Diallylmethylammonium Chloride) as a Single Deinking Agent
Flotation deinking of old newsprint (ONP) using polydiallyldimethylammonium chloride (polyDADMAC) as the only deinking agent was studied. The results demonstrate that polyDADMAC can neutralize dissolved anionics to form small particles. These small particles, together with ink, filler, and fines, strongly adsorbed onto air bubble surfaces and functioned as particle foaming agents. Therefore, no...
متن کاملNovel Sources of Fungal Cellulases for Efficient Deinking of Composite Paper Waste
Twenty thermophilic/thermotolerant fungal strains were isolated from compositing soils and screened for production of different enzymes (Endoglucanases, β-glucosidase, Fpase and xylanases) to assess their deinking efficiency. Three isolates, Aspergillus sp. AMA, Aspergillus terreus AN1, and Myceliophthora fergusii T4I, identified on the basis of morphological and sequencing of amplified ITS1-5....
متن کاملDeinking of Laser Printed Copy Paper by Chemical Different Treatments and Effect on Optical and Strength Properties of Paper
Paper recycling in an increasingly environmentally conscious world is gaining importance. Withrapid developments in deinking processes for the reuse of secondary fibers being made, therecycling process is become more and more efficient. This work investigated the effect ofchemical different treatments including H2O2 and NaOH on repulping and flotation operationsduring the deinking of laser prin...
متن کاملEnzymatic versus chemical deinking of non-impact ink printed paper.
Enzymatic versus chemical deinking is examined for MOW and photocopy prints. Several enzymatic preparations and two fibre/ink particle separation methods are tested. Deinking was monitored by image analysis and standard pulp and paper characterisation procedures. The effectiveness of the fibre/ink particle separation method depends on the ink particle's size: for smaller particles a washing ste...
