This book introduces the growing problem of microplastics pollution in the soil and aquatic environment and its interaction with other chemical pollutants. Further, it provides a detailed review of existing analysis techniques for characterization, separation, and quantification of microplastics including their merits and demerits with possible suggestions. Additionally, the regulatory need and actions for improving the economic and quality of plastic recycling, curbing microplastic littering, and stakeholders, researchers, and recyclers challenges are reviewed comprehensively. Priorities are identified to bridge the knowledge gaps for appropriate management of existing challenges. Features:...
The rapid revolution in modern industry has led to a significant increase in waste at the end of the product lifecycle. It is essential to close the loop, secure resources, and join up the circular economy. This book provides a detailed review of extraction techniques for urban mining of precious metals including gold, silver, and the platinum group. The merits and demerits of various extraction methods are highlighted, with possible suggestions for improvements. The feasibility of hybrid extraction techniques, as well as the sustainability and environmental impact of every process, is explored. Offers a comprehensive review of different techniques used in recycling technology for urban mini...
This book delves into the anthropogenic activities responsible for environmental hazards, their compensation, and potential mitigation strategies. It sheds light on the major contributors to the climate change issues aggravated by non-sustainable practices for the overexploitation of natural resources. Critical topics such as high emissions in primary mining, the recovery of energy-critical metals by urban mining, solid waste management, and forest conservation are explored, offering insights into the urgent challenges we face. Amidst the rapid demand for resources and the expansion of human habitats, the book emphasizes the need for new approaches to natural resource management and introspe...
This book reviews alternative and renewable energy resources in order to pave the way for a more sustainable production in the future. A multi-disciplinary team of authors provides a comprehensive overview of current technologies and future trends, including solar technologies, wind energy, hydropower, microbial electrochemical systems and various biomass sources for biofuel production. In addition, the book focuses on solutions for developing countries. Conventional energy sources are finite, and estimates suggest that they will be exhausted within a few decades. Finding a solution to this problem is a global challenge, and developing countries in particular are still highly dependent on fossil fuels due to their rapidly growing populations accompanied by a huge growth in primary energy consumption. Moreover, the most common conventional energy sources (coal and petroleum) are non-sustainable since their combustion exponentially increases greenhouse gas emissions. As such, there is a pressing need for clean energy based on alternative or renewable resources, not only to ensure energy supplies at an affordable price but also to protect the environment.
An ideal reference for oral board preparation, quick clinical reference, or self-assessment, Clinical Scenarios in Vascular Surgery, Third Edition, presents over 120 cases that take you step by step through the principles of safe surgical care. Edited by Drs. Gilbert R. Upchurch Jr., Peter K. Henke, Kellie R. Brown, and Caitlin W. Hicks, this indispensable study tool covers all areas of vascular surgery, including all common open surgical and endovascular interventions for both arterial and venous diseases. Using a concise, highly readable format, this updated edition ensures your familiarity with the new terminology, tests, and procedures that every contemporary surgeon needs to know.
This book provides an authoritative review of the origin and extraction of strontium and its impact on the environment. It also presents the latest strontium decontamination and remediation strategies. Around the globe, nuclear power is being recognized as a major source of energy and is expected to play a crucial role in meeting the energy requirements of present day society. However, the pros and cons have to be considered, and the safe disposal of large amounts of radionuclide wastes is becoming a matter of great concern. These wastes encompass contaminants such as heavy metals and toxic substances, which may exist in solid, liquid or gaseous forms or a combination of these, and as such, ...
Over 80% of globally produced wastewater receives little or no treatment before it is disposed into the environment. Therefore, it is urgent to develop new wastewater treatment technologies that are sustainable in the broad sense of the word, i.e. not only produce high quality effluents, but also minimise energy expenses, recover energy and nutrients, and apply technology that is appropriate in relation to the availability of skilled personnel. This book compiles the main outcomes of recent efforts to improve the design of waste stabilisation ponds, and confirms the superior performance of high rate algal ponds as a result of process intensification. Anaerobic digestion devoted to biogas pro...
Sustainable development approaches cannot be met unless waste management is addressed as a priority. Waste Recovery and Management: An Approach Toward Sustainable Development Goals presents a comprehensive examination of environmental pollution and health hazards caused by differing types of waste, its recycling and other e-waste management strategies, and potential political and legal interventions. It also presents the available carbon-recycling methods and investigates how these might be applied to reinforce waste management in industrialized countries as well as developing and emerging economies. Each chapter includes valuable data and case studies that serve as practical guidance for ac...
This book gives an overview of all the gold extraction processes along with their mechanistic study and environmental impact. Reviews extraction techniques previously employed as well as recently evolved technology for gold leaching, provides technical flow sheets for processing of ores with a diversity of lixiviants and offers a compulsory overview of every gold processing technique It also discusses recent integrated techniques including hydro- and bio-metallurgical techniques with examples
Advanced Organic Waste Management: Sustainable Practices and Approaches provides an integrated holistic approach to the challenges associated with organic waste management, particularly related to sustainability, lifecycle assessment, emerging regulations, and novel approaches for resource and energy recovery. In addition to traditional techniques, such as anaerobic digestion, composting, innovative and emerging techniques of waste recycling like hydrothermal carbonization and vermicomposting are included. The book combines the fundamentals and practices of sustainable organic waste management with successful case studies from developed and developing countries, highlighting practical applic...
