Accumulation into one source of what is known regarding the feeding value of these materials and systems which have been developed for improving their digestibility, palatability or methods of handling was the motivation for organising this book. These has been an effort to include the major categories of unconventional materials which can potentially be upgraded to provide the ruminant with needed nutrients, but certainly some have been missed. It is hoped that this treatise will prove to be a valuable tool for workers involved in improving the utilization of residues and waste products for animals.
Upgrading Waste for Feeds and Food considers how wasted or underutilized nutrients could be recovered and upgraded in order to make more food available, either directly or through animal intermediaries. This book assesses what progress had already been made in seeking a solution to the problem of large quantities of food being wasted. The topics discussed include the world outlook for food, sources of food waste, and recovery and utilization of protein from slaughterhouse effluents by chemical precipitation. The silage production, use of microbiological agents in upgrading waste for feed and food, and underutilized proteins for beverages are also elaborated. This text likewise covers the crude pectate gelling agents in heat processed foods and utilization of food wastes as raw material in the pet-food industry. This publication is a good source for agriculturists, nutritionists, and food technologists concerned with recovering wasted food.
Wood and Agricultural Residues Research on Use for Feed, Fuels, and Chemicals covers the proceedings of the 1982 “Feed, Fuels, and Chemicals from Wood and Agricultural Residues symposium, held in Kansas City and sponsored by Cellulose, Paper, and Textile Division of the American Chemical Society. Organized into seven parts encompassing 31 chapters, the book discusses the plant cell wall; the cellulose, hemicelluloses, and lignin; the lignocellulosics for ruminants; the biological and thermochemical conversion; and the approached for utilization. The introductory part describes the anatomy, permeability, ultrastructure, and digestion of plant cell wall. The following section examines the structure, characteristics, derivatives, recycle and recovery through solvent systems, and utilization for enzyme and protein production of cellulose and hemicelluloses. This section also discusses the synthesis, structure, properties, and analysis of hydroxypropyl lignin derivatives. The third section characterizes the fibrous fractions of forages and presents traditional methods for qualitative and quantitative analyses of lignocellulosics. This text includes discussions on methods for improving utilization of unconventional feed sources by ruminants; the digestion impeding factors; and the effect of chemical, physical, and biological treatments in upgrading the digestibility and nutritive value of crop residues. The subsequent sections describe the biological, chemical, physical, and thermochemical conversion of wood fibers. Such methods include fermentation, acid and steam hydrolysis, saccharification, hydrogenolysis, and pyrolysis. The concluding section covers mechanical treatments to improve lignocelluloses properties, such as steam explosion and solvent systems. This book is an ideal source of information for botanists and feed scientists and researchers.

The aim of this book is to help create new feedstuffs for poultry and farm animals from the agro-industry and to mobilize the neglected waste as a feedstuff to lower the price of animal products such as eggs, white and red meat, milk, etc. Furthermore, this book aims to contribute to the campaign against hunger in the developing world and to reduce the competition between animals and human beings for cereals and pulses. Accordingly the global pollution problem will be reduced. This book will be of great interest to all those involved in the animal feed and poultry industries, in agricultural universities, and in research establishments where animal nutrition is studied and taught.
Sustainable and Circular Management of Resources and Waste Towards a Green Deal highlights the importance of resource recovery, phosphorus management, climate action, clean energy transition, and a circular economy. The world is facing significant challenges, including climate disruption, environmental changes, pollution, and population explosion. Sustainable management of finite natural resources within the carrying capacity of the bio-geo-hydrosphere is the crux of transforming the global economy for a sustainable future. Moreover, keeping raw materials in circulation as long as possible and minimizing the amount of waste generated has grown in significance as a part of transitioning to a circular economy (CE) model. Introduces innovative solutions in green energy transition Provides case studies as examples of a circular economy implementation in selected sectors of the economy, including water and wastewater, raw materials, and construction Suggests actions to counteract climate change and its consequences for people and the planet
Waste management is a global problem that continues to increase with rapid industrialization, population growth, and economic development. As the world hurtles towards the urban future, the amount of Municipal Solid Waste (MSW) is growing very fast. Wastes are generally classified into solid, liquid, & gaseous and are broadly classified as household waste; municipal waste; commercial and non-hazardous industrial wastes; hazardous (toxic) industrial wastes; construction and demolition waste; health care wastes – waste generated in health care facilities (e.g. hospitals, medical research facilities); human and animal wastes; and incinerator wastes. The fast industrialization, urbanization, modern technology, and rapidly growing population in India have posed a serious challenge to the waste management. In India, per capita generation rate of municipal solid waste ranges from 0.2 to 0.5 kg/day. At present, the daily generation rate in South Asia, East Asia and the Pacific combined is approximately 1.0 million tons per day. Hazard management is essentially a problem solving process aimed at defining problems (identifying hazards), gathering information about them (assessing the risks) and solving them (controlling the risks). Integrated solid waste management is a comprehensive waste prevention, recycling, composting, and disposal programme. Disposing the waste in an environmentally friendly manner is highly crucial to all the nations of the world including India. The goal of urban solid waste management is to collect, treat and dispose of solid waste generated by the all the city dwellers in an environmentally, and socially satisfactory manner by using the most economical methods available. The major contents of the book are types of waste, human pathogens in animal agriculture production systems, pathogen reductions during waste treatment, aerosolization of pathogens etc. It will be a standard reference book for professionals, entrepreneurs, students, teachers, researchers, administrators, and planners of various disciplines who are directly or indirectly involved in the waste management.

The magnitude of the food-waste disposal problem cannot be understated. Utilisation of food waste is of concern to the food processing industry, consumers, environmentalists, and regulators of handling and disposal systems. Food waste is not consistent in quality, is usually high in moisture content, and is only available locally. This book focuses on the challenges of utilising both wet and/or processed food waste. The regulatory environment relating to food waste, the perspective of the end-users, and practical use as animal feed is also discussed. One of the goals of this publication, other than to give a clear explanation of the subject of food waste and its uses as animal feed, is to stimulate a need for research.
Because of its high Chemical Oxygen Demand (COD) and sheer volume, waste from food processing has significant potential to pollute land, water, and air. Both environmentally and economically, it is important to properly treat food processing wastes including the recovery of valuable products. Food Processing Waste and Utilization: Tackling Pollution and Enhancing Product Recovery discusses possible solutions to tackle food waste generation and its further utilization. It addresses process engineering economics, microbiology of waste recycling, biochemical and nutritional aspects of food waste processing. The book includes detailed guidance and case studies about utilization/valorization of food waste. Key Features Covers modern as well as conventional methods of food industry waste utilization Discusses possible solutions to tackle food waste generation and its further utilization Addresses socioeconomic considerations, environmental concerns and discusses regulations related to food processing waste Authors of this book are well-recognized researchers in their specific fields who have made important contributions to the knowledge of utilization of different food industry wastes at different levels. This book covers a wide range of breakthroughs in waste management, and is of value for students, research scholars, postdoctoral fellows and faculties pursuing careers in fields such as Bioprocess Technology, Food Technology, Food Science and Technology, Food Biotechnology, and Fermentation and Bioengineering.
