Emerging Environmental Technologies Volume Ii

In this day and age, it is unfortunate that the economic prosperity and development leads to disruption of the dynamic balance of the environment. The philosophy of sustainable development has been presented for a long period of time but it has not been able to bring about a substantial change in our society. The transformation of this philosophy into a practical reality seems to be far away – at least in the foreseeable future. In my opinion, the only way I see the revolution taking place is for us to incorporate ‘sustainability’ in our daily living and to keep pushing for a sustainable society. Meanwhile, we also need scientists to work on technologies that would lead us to that goal at a faster pace. Technologies that are ‘completely’ environmentally friendly are needed urgently. And if such technologies or ideas of one exists, a platform is required that showcases such ideas to the scientific and non-scientific audience. Through this book, I am happy to present the thoughts of seven different research groups whose work may lead us to the doorsteps of sustainable society. As scientists, most of us specialize in a sub-topic that may be related to one of the three environmental components – air, land, or water. Over a period of time, we become so engrossed with the sub-discipline of our specialization that we only have glimpses of what is happening in other disciplines.

While numerous journals and books are available in the market highlighting the developments in the field of environmental technology, none of them exclusively focuses on the technologies that would be in the forefront in near to far future. Each and every article in the book is peer-reviewed and from a different sub-discipline. Because of its interdisciplinary topics on for instance air pollution and energy production, this makes it a one book for all and serves as an excellent resource for scientists, entrepreneurs, politicians and non-governmental organizations who wish to gain information on upcoming and promising technologies.

Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Service Center. This report presents the findings from a June 1997 Environmental Technology Needs Survey conducted by EvTEC. The survey was developed to help EvTEC gain a better understanding of present practices and procedures in evaluating new products and determine how EvTEC could best respond to the needs of all stakeholders in the environmental community. The survey contained general information questions as well as specialized questions for three groups: users and regulators of environmental products; entrepreneurs who invent, develop, or market new technologies and products; and research institutes and testing labs that carry out product and technology evaluations.

Environmental Technologies Handbook provides environmental, health and safety professionals with a straightforward, easy-to-use reference guide to new and emerging pollution prevention and control technologies that will help them to meet regulatory obligations, increase sustainability, and ensure social responsibility. An international array of experts explain emerging and proven technologies for multi-media pollution and how they work, allowing readers to evaluate and choose technologies based on their needs and the technologies' cost and labor requirements. This book focuses on recent technology successes, including gasification, pyrolysis, electrochemical processes, photocatalysis, and advanced wastewater treatment technologies. Readers will find extensive coverage of the concepts of risk assessment to environmental media and the impact of advanced concepts of dose-response exposures to risk reduction practices. They will also find an explanation of the methodology and computation methods available for life cycle costing analyses and proper environmental cost accounting.

Green Technology deals with using science and technology to protect the environment as well as curb the negative impacts of human involvement. The emerging green technologies, covered in this book, will propel our economy in the near future. Their development will lead to global and sustainable powers that will impact our economics, societies, cultures, and the way of life. This book provides researchers, students, and professionals a comprehensive introduction, applications, benefits, and challenges of 15 emerging green technologies. It presents the impact of these cutting-edge technologies on our global economy and its future. The book will help a beginner to have an introductory knowledge about these emerging technologies. The main objective of the author is to provide a concise treatment that is easily digestible. It is a must-read for those graduate students or scholars who consider researching green technologies. It can also serve as a valuable resource for those business professionals who seek ways to green their processes.

SUSTAINABLE SOLUTIONS FOR ENVIRONMENTAL POLLUTIONS This second volume in a broad, comprehensive two-volume set, “Sustainable Solutions for Environmental Pollution”, concentrates on air, water, and soil reclamation, some of the biggest challenges facing environmental engineers and scientists today. This second, new volume in the two-volume set, Sustainable Solutions for Environmental Pollution, picks up where volume one left off, covering the remediation of air, water, and soil environments. Outlining new methods and technologies for all three environmental scenarios, the authors and editor go above and beyond, introducing naturally-based techniques in addition to changes and advances in more standard methods. Written by some of the most well-known and respected experts in the field, with a prolific and expert editor, this volume takes a multidisciplinary approach, across many scientific and engineering fields, intending the two-volume set as a “one-stop shop” for all of the advances and emerging techniques and processes in this area.
