Waste Management and the Environment VI

About this book

Waste management can be problematic. Especially with the emphasis in many countries now being on sustainability, there is a great need for more research on disposal methods. While we have found ways to reduce the volume of waste that needs to be disposed, questions remain about the environmental and safety aspects of certain recycled materials and the by-products of waste management activities, current technology improvements, and regulatory and monitoring problems.

Featuring papers presented at the Sixth International Conference on Waste Management and the Environment, Waste Management and the Environment VI contains contributions on the topics such as: Environmental Impact; Reduce, Reuse and Recycle (3 Rs); Cost and Benefits of Management Options; Waste Incineration and Gasification; Energy from Waste; Industrial Waste Management; Nuclear and Hazardous Waste; Agricultural Waste; Wastewater.
