dc.description.abstractChapter 1 indicates the importance of Recycled fibers in paper making globally. The source of global fiber supply is becoming an increasing concern due to deforestation and for the impact of fiber extraction on the environment. The use of recycled fibers, in the manufacture of paper, is both economical and environment friendly. Recycled fibers help in reducing deforestation, consumption of energy and chemicals for papermaking. Chapter 2 indicates the importance of Deinking process in paper making. It is a sophisticated process for facilitating the recycling of printed recycled paper. Deinking operation utilizes chemicals, mechanical and thermal energies to produce a fibrous suspension from printed recycled paper, which is sufficiently clean and bright for use to manufacture various high quality papers. The chapter covers the work carried out by different researchers in this area. Deinking is a two-step process. In the first step, the ink particles are detached from the fibers using thermo-chemi-mechanical action in the presence of chemicals in the pulper. In the second step, the ink particles detached from the fibers are removed from the pulp suspension by froth flotation. Flotation deinking process is an extremely complicated process to analyze and model. Many processes occur simultaneously during flotation where chemical, physical and hydrodynamic aspects are involved. The objective of the present work was to develop suitable Deinking technology for the uncoated Old newsprints (ONP) and its blends with other recycled papers..en_US
