Waste Management and the Environment

About this book

This title contains the proceedings of the First International Conference on Waste Management, one of the key problems of the modern world. As our awareness of the detrimental environmental effects of current waste disposal grows there is a significant need for more research on current methods such as landfill, incineration, chemical and effluent treatment and also on recycling, waste minimization, clean technologies, waste monitoring, public and corporate awareness and general education. The volume and complexity of the waste discarded intensifies this problem and creates tremendous pressure on disposal capacity forcing the international community to continuously search for optimal and, in accordance with new and more rigorous requirements, acceptable ways of dealing with this problem. Almost 80 contributions addressing a wide range of current waste management issues are contained in this volume. These are divided under the following broad subject headings: advanced waste treatment technology; methodologies and practices; clean technologies; physical, biological, chemical and thermal treatment methods; biosolids, composting and agricultural issues; organic waste for soil improvement; hazardous waste; landfills, design, construction and monitoring; separation, transformation and recycling; waste management strategies and planning; water and wastewater treatment; and community involvement and education.
