Food Waste to Animal Feed


Book Description

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.




Poultry Feed from Waste


Book Description

In developed market economies with intensive animal production systems, such as The Netherlands, many new feedstuffs have been introduced as part of the diets of ruminant and monogastric animals. These new feedstuffs are often by-products of human food processing. It is important that these by-products and also the by-products from wastes are properly evaluated with regard to the possibilities of incor porating them into livestock diets. Research on the subject of feed from waste, its processing and its use in the nutrition of poultry has increased considerably during the last decade. The Department of Animal Nutrition of Wageningen Agricul tural University (WAU), Wageningen, The Netherlands, in close co operation with the Poultry Feeding and the Processing Industry, has been active in this field. In order to update research and to expedite further work in this field, a comprehensive review of the literature on the subject of feed from waste was made. Such a study would not only bring the industry up to date on the subject but could also indicate specific topics which may be of great value for developing market economies. Poultry scientists and technologists suggested that a review would fill a need as a reference and textbook, not only for the industry but also for undergraduates and graduates of agricultural colleges and extension services all over the world.




Animal Manure


Book Description

The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.




Air Emissions from Animal Feeding Operations


Book Description

Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Edible Insects in Sustainable Food Systems


Book Description

This text provides an important overview of the contributions of edible insects to ecological sustainability, livelihoods, nutrition and health, food culture and food systems around the world. While insect farming for both food and feed is rapidly increasing in popularity around the world, the role that wild insect species have played in the lives and societies of millions of people worldwide cannot be ignored. In order to represent this diversity, this work draws upon research conducted in a wide range of geographical locations and features a variety of different insect species. Edible insects in Sustainable Food Systems comprehensively covers the basic principles of entomology and population dynamics; edible insects and culture; nutrition and health; gastronomy; insects as animal feed; factors influencing preferences and acceptability of insects; environmental impacts and conservation; considerations for insect farming and policy and legislation. The book contains practical information for researchers, NGOs and international organizations, decision-makers, entrepreneurs and students.




Biobased Products from Food Sector Waste


Book Description

In the past, food waste has been used to produce biogas and biofuels, fertilizers, and animal feed. Using it as a feedstock for innovative biorefineries is not only an ethical issue but also a smart application of the circular economy. This book explores the zero-waste concept in the thriving biobased sector, proposing technologies and procedures to meet the sustainable development goals. The volume categorizes food waste sources and proposes an impressive number of high value-added compounds (e.g., platform chemicals, enzymes, nutraceuticals, antioxidants, organic acids, phosphate, bioadsorbents, pectin, solvents, and pigments) that can be obtained in a sequential biocascade, via chemical, biochemical, thermal, and physical technologies. The synthesis of bioplastics from food waste, their copolymerization and blending, as well as the production of biocomposites and bionanocomposite with biofillers from food scraps, are presented: eluding the cost of waste disposal, reducing biobased materials price, and avoiding using edible resources as a starting material for biobased items are the main beneficial peculiarities of the process. The Authors illustrate challenging characteristics of new biobased materials, such as their mechanical and physico-chemical features, their biodegradability, compostability, recyclability, chemical compatibility, and barrier properties. The volume also delves into socioeconomic considerations and environmental concerns related to the upcycling of food waste, as well as the safety and life cycle assessment of biobased products. Finally, the authors address how advances in digital technology can make food waste upcycling a negative-cost process and discuss best practices to practically implement the biorefinery concept. Research gaps and needs are suggested, and recommendations for food waste handling and management during this COVID-19 pandemic are provided.
