When the Nobel Prize Committee recognized the importance of green chemistry with its 2005 Nobel Prize for Chemistry, this relatively new science came into its own. Although no concerted agreement has been reached yet about the exact content and limits of this interdisciplinary discipline, there seems to be increasing interest in environmental topics that are based on the chemistry embodied in this subject. Linking green chemistry practice to environmental sustainability, Green Chemistry for Environmental Sustainability illustrates the efforts being made to remediate a scathed environment into a pristine one. Links Green Chemistry Practice to Environmental Sustainability Eminent international experts present research on and the application of green chemistry and engineering in addressing current issues of an environmental and social nature. They cover sustainable development and environmental sustainability with chapters on green chemistry and engineering research, the design and synthesis of environmentally benign chemical processes, green approaches to minimize and/or remediate environmental pollution, the development of biomaterials, biofuel, and bioenergy production, biocatalysis, and policies and ethics in green chemistry. The book also explores economics, environmentally benign technologies for greener processes, computational methods and modeling, and green approaches to minimize air and water. Green chemistry has brought a relatively prompt and positive paradigm shift in the overall use and management of natural resources and raw materials for the development of society with a subtle promise to cause far less pronounced harm to the environment. This text provides insight into the chemical and biochemical technologies that are being studied, optimized, and eventually developed to promote environmental sustainability. It provides up-to-date information on selected fields where the principles of green chemistry are being embraced for safeguarding and improving the quality of the environment.

Chemistry is considered to be one of the prime causes of environmental pollution and degradation. The United Nations General Assembly also addressed the environmental challenges in its Sustainable Development Goals (SDGs), which have been adopted in 2015. A closer look shows that to meet these goals chemistry will play an important role. Green chemistry encompasses design and synthesis of environmentally benign chemical processes, green approaches to minimize and/or remediate environmental pollution, the development of biomaterials, biofuel, and bioenergy production, biocatalysis, and policies and ethics in green chemistry. When products in use today become waste, we need to treat that waste so that hazardous substances are not re-circulated into new products. In this context, circular economy is also an important point of discussion, which focuses on recycling, reuse and use of renewable sources. The theme of the International Conference on "Green Chemistry in Environmental Sustainability & Chemical Education (ICGC-2016) held in Delhi from 17-18 November 2016 was to discuss the emerging green trends in the direction of sustainability and environmental safety. ICGC-2016 consisted of keynote, plenary and invited lectures, panel discussion, contributed oral papers and poster presentations. The conference provided a platform for high school students, undergraduate and postgraduate students, teaching fraternity and young researchers to interact with eminent scientists and academicians from all over the world who shared their valuable views, experience and research on the harmonious methods in chemistry for a sustainable environment. This volume of proceedings from the conference provides an opportunity for readers to engage with a selection of refereed papers that were presented during the ICGC-2016 conference. The overarching goal of this book is to discuss most recent innovations and concerns in green chemistry as well as practical challenges encountered and solutions adopted to remediate a scathed environment into a pristine one. It includes an extensive variety of contributions from participants of ICGC-2016 that demonstrate the importance of multidisciplinary and interdisciplinary approach to problem solving within green chemistry and environmental management. The proceedings is thus a green chemistry monograph resulting from the fruitful deliberations in the conference, which will deeply enhance awareness about our responsibility towards the environment.

The study of environmental interfaces and environmental catalysis is central to finding more effective solutions to air pollution and in understanding of how pollution impacts the natural environment. Encompassing concepts, techniques, and methods, Environmental Catalysis provides a mix of theory, computation, analysis, and synthesis to support the latest applications in biocatalysis, green chemistry, environmental remediation and our understanding of the interaction of pollutants with natural systems. The book focuses on several aspects of environmental catalysis. Surface catalysis of airborne particles - including ice, trace atmospheric gases, aerosolized soot nanoparticles, and mineral dust surfaces - as well as particles in contact with ground water and their role in surface adsorption, surface catalysis, hydrolysis, dissolution, precipitation, oxidation and ozone decomposition is explored. It continues by presenting catalysis as the key technology for treating emissions and reducing waste by-products. The authors review the theory behind catalytic converters and discuss the effectiveness of several catalysts, including zeolites and nanoparticles, in treating emissions, aromatic hydrocarbons, and chemical warfare agents. They also survey the use of biocatalysis in environmental remediation, and industrial processes, particularly in the production of transportation fuels, fine chemicals, and pharmaceuticals. Then the authors explain how enzymes can remove chlorinated organics and metals and how microbes can metabolize toxic chemicals from groundwater. Lastly, they discuss the principles of green chemistry, including the use of environmentally benign solvents, biphasic catalysts, and other alternative solvents to recover and recycle catalysts based on heavy metals. With increasing ground water pollution, increasing particulates in the atmosphere, and the increasing need to remove pollutants from industrial and automotive sources, Environmental Catalysis addresses issues that will be instrumental in current and future environmental challenges we face.

The residual wilderness & beauty of nature excites not only me but each one of us from our core & any damage to the 'mother earth' wittingly or unwittingly by our own actions certainly move us & create an intrinsic desire to protect our nature & environment. Right from nomadic or pastoral economy to the settled economy & to this date of so called unbridled development for our own comfort, we have been exploiting our nature with unbridled greed & impunity without realizing the fact that these dastardly acts of ours inflict irreparable damage to our 'mother earth' & environment. From industry to chemistry & from desires to development - all lead somehow or other to air, water, soil & several other forms of pollution & finally to global climate change & species extinction. Moreover, the ''evolutes'' from fossil-fuels to those from labs & coal-fired electricity generating units inflict considerable damage to our environment. From this state of desperation & desolation & conflict between so called development & conservation issues, arose a host of committed individuals worldwide who took the onus to protect our environment from further degradation. In fact, damage to the environment over the years has become so savage & brute due to uncontrolled exploitation of the nature, that the environmental protection has become one of the prime concern of the humanity these days. In this context the publication of this book/compilation on 'Green Chemistry for Greener Environment' has become so important.

Scholars and policymakers alike agree that innovation in the biosciences is key to future growth. The field continues to shift and expand, and it is certainly changing the way people live their lives in a variety of ways. With a large share of federal research dollars devoted to the biosciences, the field is just beginning to live up to its billing as a source of innovation, economic productivity and growth. Vast untapped potential to imagine and innovate exists in the biosciences given new tools now widely available. In The Biologist's Imagination, William Hoffman and Leo Furcht examine the history of innovation in the biosciences, tracing technological innovation from the late eighteenth century to the present and placing special emphasis on how and where technology evolves. Place is often key to innovation, from the early industrial age to the rise of the biotechnology industry in the second half of the twentieth century. The book uses the distinct history of bioinnovation to discuss current trends as they relate to medicine, agriculture, energy, industry, ecosystems, and climate. Fast-moving research fields like genomics, synthetic biology, stem cell research, neuroscience, bioautomation and bioprinting are accelerating these trends. Hoffman and Furcht argue that our system of bioscience innovation is itself in need of innovation. It needs to adapt to the massive changes brought about by converging technologies and the globalization of higher education, workforce skills, and entrepreneurship. The Biologist's Imagination is both a review of past models for bioscience innovation and a forward-looking, original argument for what future models should take into account.
