Preface

Recent developments connected to increased environmental awareness, recognition of global climate problems, and the advent of bioeconomies and biorefineries have brought cellulosic products back into the public consciousness as valuable biomaterials and chemical feedstocks. In this context, the pulp and paper industries are increasingly regarded as businesses engaged in high-tech innovation.

The development of biorefinery methods has highlighted the characteristics of celluloses such as biomineralization, recycling, conversion, and permanence. Today, the cellulose discipline is one of the most rapidly advancing fields in the natural and physical sciences. Cellulose plays and will continue to play a dominant role in the universal appearance of bioeconomies, leading the way from fossil-based chemical industries to true biorefineries. Today's uses for cellulose, tissues, fibers, and cellulose derivatives, including paper products, are only the beginning.

This book begins by addressing the conversion of biomass waste products into valuable products like cellulose hydrogel films, which are important in cell regeneration. The other chapters explain the application of cellulose derivatives in mineral processing, cellulose derivatives (CDs) that have been recognized as anionic water-soluble, non-toxic, biocompatible, and biodegradable polysaccharides. Also one chapter deals with de-inking of MOW type paper using enzymes and. One chapter covers bacterial cellulose, an alternative ecological materials have been used as viscosity regulators, thickening agents, sizing agents, coating agents, emulsion stabilizers, and electrode binders in various industries.

This book conveys the fascination of contemporary cellulose science, including its versatility, applicability, challenges, and bright future.
