This book explores the concept and methods of waste management with a new approach of biological valorization. Waste valorization is a process that aims to reduce, reuse, and recycle the waste into usable, value-added, and environmental benign raw materials which can be a source of energy. The book brings together comprehensive information to assert that waste can be converted into a resource or a raw material for value addition. Waste valorization imbibes the natural recycling principles of zero waste, loop closing, and underlines the importance of sustainable and environmentally friendly alternatives. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the contours of waste valorization principles, biovalorization technologies for diverse group of wastes including agricultural, municipal, and industrial waste. It further discusses the emerging paradigms of waste valorization, waste biorefineries, valorization technologies for energy, biofuel, and biochemical production. The book meets the growing global needs for a comprehensive and holistic outlook on waste management. It is of interest to teachers, researchers, scientists, capacity builders and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of biotechnology and environmental sciences.

This edited book focuses on agricultural and food waste biomass valorization in various fields such as energy and environment and the development of several other value-added products. The chapters in this book cover different areas like sources of agricultural and food wastes, recent trends on waste utilization, innovations and sustainability of techniques, and challenges associated with valorization of wastes. In the last few decades, scientists and researchers of different countries predicted that waste material generated due to global problems can be used as a potential feeding material for the manufacturing of different valuable products. Hence, there is a need for more research and development of several other value-added products from waste materials. Proper utilization of these waste materials has been discussed in this book. It also covers the bioactive recovery from food waste, health benefits of extracted bioactive, and utilization of valorized products. The book also explores future technological challenges and sustainability issues. This title is a great resource for environmental and chemical engineers, food scientists, food researchers and technologists, as well as for students and professionals working in this field.

Zusammenfassung: This volume discusses the reduction, recycling, and reuse of industrial and agricultural biomass wastes to develop value-added products using environmentally sustainable practices and technologies. Through these waste valorization approaches, biomass waste materials can be converted into useful bio-chemical products, sustainable construction materials, polymers, bio-energy, and bio-fuel as sustainable alternatives to products and materials with negative environmental and health consequences. The chapters highlight the development and implementation of eco-friendly solutions to biomass waste production with the aim of reducing natural resource deterioration, bolstering rural and small-scale business systems in communities impacted by pollution and climate change, and providing power from residual biomass to broadly reduce environmental impacts through improved waste management practices. The book is intended to be a useful resource for researchers, policymakers, NGOs, government agencies, and local community authorities working in waste management and environmental sustainability

Food waste is becoming an important and growing concern at both local and global levels. According to the Food and Agriculture Organization of the United Nations (FAO), one-third of all food production is wasted globally, and in particular, 1.3 billion tons of food produced for human consumption is wasted per year, representing an economic loss of EUR 800 billion. The main foods wasted are represented by vegetables, fruits, meat, and fish. Considering the high availability and the composition of food waste, there is an increasing interest in their bio-valorization. Moreover, according to the global Sustainable Development Goals (SDGs 12 and 13), an appropriate waste management represents an essential prerequisite for the sustainable development. This reprint collects interesting manuscripts regarding innovative research focused on food waste valorization through fermentation processes for obtaining value-added products such as enzymes, feed additives, biofuels, animal feeds as well as other useful chemicals or products, food-grade pigments, and single-cell protein (SCP), enhancing food security and environmentally sustainable development.

Enzymes play a vital role in the enzymatic hydrolysis of waste for its conversion to useful value-added products. Enzymatic Hydrolysis of Waste for Development of Value-added Products focusses on the role of key enzymes such as cellulase, hemicellulases, amylases, and auxiliary enzymes (LMPOs), used in the hydrolysis step of the biorefinery setup. Further, it discusses the role of enzymes in the generation of reducing sugars and value-added compounds, with major emphasis on recent advances in the field. The mechanism, importance, type, evolution, and role of enzymes in hydrolysis constitute the crux of this volume, which is illustrated with examples and pertinent case studies. Features: • Explores the role of hydrolyzing enzymes in the breakdown and transformation of biomass hydrolysis. • Discusses the potential of auxiliary enzymes (LPMOs) for enhancing hydrolysis potential. • Covers recent developments in the field of enzymatic-assisted hydrolysis of waste for conversion of waste to value-added products. • Deliberates all possible products that can be generated from enzymatic hydrolysis of waste and their potential utilization. • Elucidates the limitations and advantages of enzyme-based hydrolysis and possible strategies for moving from the laboratory to large scale industries. This book is aimed at graduate students, researchers and related industry professionals in biochemical engineering, environmental science, wastewater treatment, biotechnology, applied microbiology, biomass-based biorefinery, biochemistry, green chemistry, sustainable development, waste treatment, enzymology, microbial biotechnology, and waste valorization.

From Waste to Value investigates how streams of organic waste and residues can be transformed into valuable products, to foster a transition towards a sustainable and circular bioeconomy. The studies are carried out within a cross-disciplinary framework, drawing on a diverse set of theoretical approaches and defining different valorisation pathways. Organic waste streams from households and industry are becoming a valuable resource in today’s economies. Substances that have long represented a cost to companies and a burden for society are now becoming an asset. Waste products, such as leftover food, forest residues and animal carcasses, can be turned into valuable products such as biomaterials, biochemicals and biopharmaceuticals. Exploiting these waste resources is challenging, however. It requires that companies develop new technologies and that public authorities introduce new regulation and governance models. This book helps policy-makers govern and regulate bio-based industries, and helps industry actors to identify and exploit new opportunities in the circular bioeconomy. Moreover, it provides important insights for all students and scholars concerned with renewable energy, sustainable development and climate change.
