Book excerpt: 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.
