Use of Enzyme and Ultrasonic Energy in Paper Recycling

Abstract

Paper has undeniable key roles in establishing civilization, archiving and transferring knowledge. Paper is in all parts of daily life for different purposes today and its consumption is getting at unbelievable level. For solving the problems related to insufficient raw materials, the sustainable recycling technologies should be developed rather than concentrating on sustainable forestry practices. In this sense, extracting all materials from waste papers with economical and environmentally friendly methods are extremely important. In this study, some results obtained from an experimental study carried out on the deinking of toner printed office papers with the help of enzymes and ultrasonic energy were discussed and paper industry was examined in respect to recycling and environment.
