This unique volume covers many aspects of waste management in developing countries. There is a focus on various sources of waste including the pressing issues of agricultural, medicinal, industrial, and urban waste, and emerging problems with e-waste, nanowaste, and microplastics in marine environments. This volume addresses the critical environmental issues resulting from rapid urbanization and industrialization, particularly in the developing world. High-end technologies that can utilize waste as a resource to generate products, processes, and revenue are also discussed.
Features
Presents technical perspectives on emerging wastes in developing economies
Discusses the issues of e-waste, which is growing three times faster than general municipal waste globally
