‘Waste’ is generally identified as goods or material that are perceived to be mostly valueless. However, objects that are perceived to be waste based on consumers’ object valuation can be redefined to create value. This requires a multitude of efforts using different strategies in waste prevention and management. This book is an edited collection of various chemical approaches used for valorization of solid wastes, particularly, waste electrical and electronic equipment, plastic waste, and agro-residue waste, that provide research insights into the concept "waste-to-energy". Covering a variety of interdisciplinary topics on waste treatment and resource recovery makes the book one for all that serves as an excellent reading material for engineers, science scholars, entrepreneurs, and organizations who are working in the field of waste management.

Waste materials in the solid form tend to be bulky and difficult to handle and transport. Its management could happen through physical, thermal, chemical or biological processing stages, with the exact sequence of and their operational optima being decided by the waste composition. In recent years, energy crisis and increased waste production have been undoubtedly major issues of concern. As we mentioned in the previous volume of this book, defining waste is crucial in terms of identifying the most adequate approach to recycle or recover resources from the waste. Various chemical, biochemical, and biological approaches are being investigated widely by researchers for waste valorization. Volume 2 of this book brings together the leading researchers working on solid waste management using biological and biochemical approaches.

Provides a comprehensive overview on developing sustainable practices for waste minimization via green metal extraction from waste streams This book introduces readers to sustainable management and defines the challenges as well as the opportunities in waste stream management. It starts by covering conventional technologies for metal extraction then focuses on emerging tools and techniques such as green adsorption, bioleaching, and chelation. It also discusses the scale-up and process intensification of metal extraction from waste streams from process design to pilot plan. Sustainable Metal Extraction from Waste Streams begins by covering sustainability-related constructs and illustrates the pre-requisites for sustainable management of waste streams. It then introduces the basics of solid waste handling, ranging from an analysis of the relevance, categories of wastes, consequences of untreated waste disposal into the environment, government initiatives, management strategies, and unit operations for pre-treatment of wastes. The book also looks at widely accepted, conventional metal extraction technologies like hydro and pyro metallurgical methods; discusses the possibility of sustainable green processes for metal extraction; and introduces the recently deployed coiled flow inverter process. -Provides a comprehensive collection of the conventional, emerging, and future technologies for metal extraction from industrial waste and electrical & electronic equipment in a sustainable way -Demonstrates trans-disciplinary research as an executable direction to achieve the sustainable governance of natural resources and solid waste management -Presents a dedicated section on scale-up and process intensification of metallurgical processes -Summarizes various aspects of novel processes ranging from basic concepts, benchmark performance of technologies on lab scale, and recent research trends in metal extraction Covering a variety of interdisciplinary topics on resource optimization and waste minimization, Sustainable Metal Extraction from Waste Streams is an excellent resource for engineers, science students, entrepreneurs, and organizations who are working in the field of waste management and wish to gain information on upcoming sustainable processes.
