Each recycling technology is described with respect to:

• Objectives 
• Benefits and limitations 
• Environmental requirements 
• Design criteria of the process 
• Use of the recycled products 
• Public health aspects 
• Organic Waste Recycling 
• Includes case studies, examples, exercises and questions

This book is intended as a text or reference book for third or fourth year undergraduate students interested in environmental science, engineering and management, and graduate students working in the environment-related disciplines. It also serves as a reference text for policy makers, planners and professionals working in the environment and sustainable development fields.
