A new chronology is introduced to address the history of chemistry, with educational purposes, particularly for the end of the twentieth century and here identified as the fifth chemical revolution. Each revolution are considered in terms of the Kuhnian notion of ‘exemplar,’ rather than ‘paradigm.’ This approach enables the incorporation of instruments, as well as concepts and the rise of new subdisciplines into the revolutionary process and provides a more adequate representation of such periods of development and consolidation. The fifth (...) revolution developed from 1973 to 1999 and is characterized by a deep transformation in the very heart of chemistry. That is to say, the size and type of objects, the way in which they must be done and the time in which they are transformed. In one way or another, chemistry’ limits had been set out. (shrink)

The drive towards clean technology in the chemical industry with an increasing emphasis on the reduction of waste at source requires a level of innovation and new technology that the chemical industry is beginning to adopt. The green chemistry revolution provides an enormous number of opportunities to discover and apply new synthetic approaches using alternative feedstocks; ecofriendly reaction conditions, energy minimizations and the design of less toxic and inherently safer chemicals. In this review exciting opportunities and some successful examples of (...) green chemistry in practice are described. While developments in the 20th century have brought various social and economic benefits to the people but these changes have also caused a range of environmental problems at both local and global levels. Over recent years, sustainable development has been accepted by government, industry and the public as a necessary goal for achieving social, economic and environmental objectives. Within this, green chemistry plays a key role in maintaining and improving quality of our life and preserving natural environments. The term ‘ Green Chemistry’ was first coined by the US Environmental Protection Agency in the early 1990s and major interest in green chemistry in the US began in earnest with the passage of the ‘Pollution Prevention Act’ of 1990. Thus Green Chemistry becoming a formal focus of the EPA in 1991. (shrink)

Using the Public Value Mapping framework, I address the values successes and failures of chemistry as compared to the emerging field of green chemistry, in which the promoters attempt to incorporate new and expanded values, such as health, safety, and environmental sustainability, to the processes of prioritizing and conducting chemistry research. I document how such values are becoming increasingly public. Moreover, analysis of the relations among the multiple values associated with green chemistry displays a greater internal coherence and logic than (...) for conventional chemistry. Although traditional chemistry research has successfully contributed to both economic and values gains, there have been public values failures due to imperfect values articulations, failure to take a longer-term view, and inertia within a system that places too much emphasis on science values. Green chemistry, if implemented effectively, has potential to remedy these failures. (shrink)

This study discusses the relationship between Green Chemistry and Environmental Sustainability as expressed in textbooks and articles on Green Chemistry authored by their promoters. It was found that although the Brundtland concept of Sustainable Development/Sustainability has been mentioned often by green chemists, a full analysis of that relationship was almost never attempted. In particular, green chemists have paid scarce attention to the importance of The Second Law of thermodynamics on Environmental Sustainability and the consequences of the limitations it imposes on (...) Green Chemistry, which are discussed in this paper. (shrink)

This article provides an overview of the origins and development of green chemistry. Aiming to contribute to the understanding of green chemistry, basically from a historical point of view, this overview argues that contextual influences and the user friendliness of the term are drivers for the explosive growth of green chemistry. It is observed that political support for its development has been significant, in which the Pollution Prevention Act of 1990 was a formal political starting-point, but informally the origins of (...) green chemistry go back to before 1990. US EPA played an important role in all this, but did not solely contribute to the growth of green chemistry. (shrink)
