MANAGEMENT OF ELECTRONIC WASTE Holistic view of the current and future trends in electronic waste management, focusing on recycling, technologies, and regulations Management of Electronic Waste delivers a complete overview of all aspects related to the toxicity characterization of electronic wastes, along with other important topics including resource recovery, recycling strategies, biotechnological advancements, and current perspectives on waste generation and management. The book presents hazards associated with conventional recycling methods and highlights environmentally compatible economic approaches for resource recovery, along with eco-friendly strategies for management of electronic wastes. The high metallic content, heterogeneous and composite nature of e-wastes make them a rich secondary reservoir of metals. The book explores the valuable potential of e-waste and highlights the eco-friendly, sustainable technologies and recycling strategies for the profitable and effective conversion of waste to wealth. Written by a highly qualified and internationally renowned author, Management of Electronic Waste covers sample topics such as: Rise of e-waste generation paired with rising economies and mounting demand for electrical and electronic devices, with a country-by-country breakdown Status of e-waste management and recycling efforts around the world, along with key processes that drive e-waste recycling Macroeconomic trends between global demand and supply for metal resources and the transition of linear to circular economy Bioleaching, an economic and green approach for recovery of metals, from e-waste and other low grade metal repositories Different metallurgical approaches for extraction and recovery of resources from e-waste and their pros and cons Filling a gap on the understudied biotechnological recycling techniques and methods for mitigating environmental pollution caused by electronic waste, Management of Electronic Waste serves as an excellent guide on the subject for electronic waste producers, consumers, recycling industries, policy and law makers, academicians, and researchers.

Current development results in a linear flow from raw material to waste, which cannot be sustainable in the long term. Plus, a global population of 7 billion people means that there are 7 billion waste producers in the world. At present, dumping and landfilling are the primary practices for getting rid of municipal solid waste (MSW). However, this waste contains resources that we’ve yet to utilize. To create sustainable societies, we need to approach zero waste by recovering these resources. There are cities and countries where zero waste is close to becoming a reality. Landfilling of organic waste is forbidden in Europe, and countries such as Sweden, Germany, Belgium, and Switzerland have developed a variety of technologies to recover resources from MSW. Resource Recovery to Approach Zero Municipal Waste explores the solid waste management laws and regulations of different countries, comparing the latest resource recovery technologies and offering future perspectives. The book tackles the many technical, social, ecological, economical, and managerial aspects of this complex subject while promoting the development of sustainable societies to achieve a greener global environment.

In the digital age, the relentless growth of data centers and cloud computing has given rise to a pressing dilemma. The power consumption of these facilities is spiraling out of control, emitting massive amounts of carbon dioxide, and contributing to the ever-increasing threat of global warming. Studies show that data centers alone are responsible for nearly eighty million metric tons of CO2 emissions worldwide, and this figure is poised to skyrocket to a staggering 8000 TWh by 2030 unless we revolutionize our approach to computing resource management. The root of this problem lies in inefficient resource allocation within cloud environments, as service providers often over-provision computing resources to avoid Service Level Agreement (SLA) violations, leading to both underutilization of resources and a significant increase in energy consumption. Computational Intelligence for Green Cloud Computing and Digital Waste Management stands as a beacon of hope in the face of the environmental and technological challenges we face. It introduces the concept of green computing, dedicated to creating an eco-friendly computing environment. The book explores innovative, intelligent resource management methods that can significantly reduce the power consumption of data centers. From machine learning and deep learning solutions to green virtualization technologies, this comprehensive guide explores innovative approaches to address the pressing challenges of green computing. Whether you are an educator teaching about green computing, an environmentalist seeking sustainability solutions, an industry professional navigating the digital landscape, a resolute researcher, or simply someone intrigued by the intersection of technology and sustainability, this book offers an indispensable resource.

This book is devoted to CO2 capture and utilization (CCU) from a green, biotechnological and economic perspective, and presents the potential of, and the bottlenecks and breakthroughs in converting a stable molecule such as CO2 into specialty chemicals and materials or energy-rich compounds. The use of renewable energy (solar, wind, geothermal, hydro) and non-fossil hydrogen is a must for converting large volumes of CO2 into energy products, and as such, the authors explore and compare the availability of hydrogen from water using these sources with that using oil or methane. Divided into 13 chapters, the book offers an analysis of the conditions under which CO2 utilization is possible, and discusses CO2 capture from concentrated sources and the atmosphere. It also analyzes the technological (non-chemical) uses of CO2, carbonation of basic minerals and industrial sludge, and the microbial-catalytic-electrochemical-photoelectrochemical-plasma conversion of CO2 into chemicals and energy products. Further, the book provides examples of advanced bioelectrochemical syntheses and RuBisCO engineering, as well as a techno-energetic and economic analysis of CCU. Written by leading international experts, this book offers a unique perspective on the potential of the various technologies discussed, and a vision for a sustainable future. Intended for graduates with a good understanding of chemistry, catalysis, biotechnology, electrochemistry and photochemistry, it particularly appeals to researchers (in academia and industry) and university teachers.
