As the population of the world is rising, so is the amount of waste being produced. The mismanagement of waste has led to serious ecological damage as well as social and environmental harm. Waste management refers to the field of using various actions, activities, technologies and methods to manage waste. It also includes transport, collection, disposal and treatment of waste. To keep this planet clean and habitable waste management is the need of the hour. While the waste management hierarchy also applies to the management of bio-waste, in specific cases it may be justified to depart from it as the environmental balance of the various options available for the management of this waste depends on a number of local factors, inter alia collection systems, waste composition and quality, climatic conditions, the potential of use of various waste-de-rived products such as electricity, heat, methane-rich gas or compost.
This is a complex procedure as there are different categories of waste such as solid, liquid, biodegradable and non-biodegradable. Each of these requires different methodologies for disposal. Most of the topics introduced in this book cover new techniques and applications related to management of waste. Different approaches, evaluations and advanced studies have been included in it. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. The readers would gain knowledge that would broaden their perspective about this field. This book includes contributions of experts, which will provide innovative insights into this field.
