Biodegradation and Bioremediation


Book Description

In this volume, experts from universities, government labs and industry share their findings on the microbiological, biochemical and molecular aspects of biodegradation and bioremediation. The text covers numerous topics, including: bioavailability, biodegradation of various pollutants, microbial community dynamics, properties and engineering of important biocatalysts, and methods for monitoring bioremediation processes. Microbial processes are environmentally compatible and can be integrated with non-biological processes to detoxify, degrade and immobilize environmental contaminants.




Applied Bioremediation and Phytoremediation


Book Description

The huge expansion of the chemical and petroleum industries in the twentieth century has resulted in the production of a vast array of chem ical compounds and materials that have transformed our lives. The associated large-scale manufacturing, processing and handling activi ties have caused a serious deterioration in environmental quality and created threats to human health. These negative impacts have led to responses and regulations requiring remedial action in support of envi ronmental sustainability. of biotechnological methods through bioremediation, Application has gained prominence as an option for soil remediation methods. Bioremediation is a multidisciplinary approach where biologists, chem ists, soil scientists and engineers work as team to develop and imple ment remediation processes. Bioremediation has now been used successfully to remediate many petroleum-contaminated sites. However, there are as yet no commercial technologies commonly used to reme diate the most recalcitrant contaminants. Nevertheless, bioremediation is a rapidly advancing field and new bio-based remedial technologies are continuing to emerge.




Hazardous Waste Management


Book Description

This book presents a comprehensive overview of hazardous waste and hazardous waste management. It describes the various types and constituents of hazardous waste, discusses hazardous waste management techniques and technologies, and highlights techno-economic considerations and key issues in remediation. It is a useful resource for waste management and treatment professionals, chemical engineers, technicians, medical professionals, and environmental regulators as well as students studying hazardous waste management, environmental engineering, and environmental science.




Geopolymers and Other Geosynthetics


Book Description

Geopolymers are applied to material classes that are chemically transformed from low crystallinity aluminusilicates to three-dimensional inorganic polymers (tectosilicates). The resulting material has properties similar to natural minerals, so it is called artificial rock. However, these materials exhibit a chemical composition and mineralogical structure similar to feldspar, feldspathoidal, and zeolites consisting of a polymeric Si–O– Al framework, with a microcrystalline or an amorphous structure. Although geopolymers have attractive engineering and environmental characteristics, there are some challenges in commercializing these materials. In this book, these challenges will be addressed along with introducing the functional geopolymers as an effective approach to commercializing these materials and making them economically feasible.

Environmental Soil Remediation and Rehabilitation


Book Description

This book provides a comprehensive overview of innovative remediation techniques and strategies for soils contaminated by heavy metals or organic compounds (e.g. petroleum hydrocarbons, NAPLs and chlorinated organic compounds). It discusses various novel chemical remediation approaches (in-situ and ex-situ) used alone and in combination with physical and/or thermal treatment. Further, it addresses the recovery of NAPLs, reuse of leaching solutions, and in-situ chemical reduction and oxidation, and explores the chemical enhancement of physical NAPLs recovery from both practical and theoretical perspectives. Also presenting the state-of-the-art in waste-assisted bioremediation to improve soil quality and the remediation of petroleum hydrocarbons, the book is a valuable resource for students, researchers and R&D professionals in industry engaged in the treatment of contaminated soils.




Microbial Technologies in Industrial Wastewater Treatment


Book Description

Microbial technology using live, naturally occurring microorganisms in industrial wastewater treatment, is the most effective and innovative method to degrade environmental pollutants such as heavy metals, radionuclides, xenobiotic compounds, organic waste, and pesticides, or to prevent their contamination of the environment. The technology includes several techniques such as biostimulation, biogeneration, bioaccumulation, and biosorption. This book describes the limitations and challenges associated with some generally accepted bioremediation strategies and evaluates the possible applications of these corrective strategies to eliminate toxic pollutants from the environment. The environmental contamination by both natural and anthropogenic sources is, nowadays, an international concern. To decontaminate soils, sediments, and water polluted by anthropogenic activities, scientists and technologists have developed various technologies over the years; however, not only do we have to pay a high cost for physical and chemical environmental technologies but also they sometimes are not ecological or safe. Therefore, we have realized the necessity to develop viable technologies that use microbes and plants to avoid these issues. This book is designed for engineers, scientists, and other professionals who are seeking introductory and advanced knowledge of the principles of nanotechnology, and those who work or are interested in the environmental microbiology or bioremediation field.
