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 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 کاملGrass Species as Raw Material for Pulp and Paper
Paper has been made from grasses and other non-wood materials for over 1900 years. Wood is a relatively new papermaking fibre, only 100 years old. Today the commercial non-wood pulp production accounts for 6% of the global pulp production. The main source for the raw material is plants of the Gramineae family. Research on nonwood material has concentrated on grasses like Miscanthus, Phalaris, S...
متن کاملInfluence of paper and ink on deinking of inkjet prints
Hewlett-Packard (HP) is actively engaged in external and internal research to ensure that deinkability of the current recycled paper streams is maintained as the percentage of digital prints in deinking mill furnish increases. As part of this effort, HP is working to understand how ink and paper interactions affect the flotation deinking process. Results continue to show that paper type and des...
متن کاملEffect of Sewage Sludge and Furnace Waste on the Content of Selected Elements in the Sward of Legume-grass Mixture
Industrial landfills resulting from operations of various industries, particularly power generation, create specific habitat conditions for flora. Among the waste which may be used for recultivation of dumping heaps there is sewage sludge, which contains a considerable amount of nutrients crucial for plants. This investigation aimed at identification of the effect of sewage sludge and furnace a...
