Green chemistry prevention

Green chemistry eliminates waste at source that is, it is primary pollution prevention rather than end-of-pipe waste remediation, as is inherent in e first principle of green chemistry prevention is better than cure. Since the mid-1990s, the concept of green chemistry has been widely embraced in both industrial and academic circles [9], One could say that sustainable development is our ultimate common goal and green chemistry is a means to achieving it.

The notions of mass balance, selectivity and conversion (see Figure 1.6) need to be added to the idea of yield when chemists consider a chemical transformation, particularly if this consideration takes place in the context of pollution prevention or green chemistry. ... 

Green Chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical processes. This non-regulatory approach for pollution prevention occupies a pivotal position in the management of hazardous substances and has been quite successful as evidenced, for example, in the United States by the Presidential Green Chemistry Challenge Awards. ... 

In the United States, several federal programmes and focused regulations that incorporate elements of green chemistry have been put into place to reduce risks. The Pollution Prevention Act of 1990 has clearly stated that pollution prevention at the source is the highest and most desired level of environmental protection. ...

The use of nanomaterials is important in environmental science and technology in terms of their applications in green chemistry, pollution prevention, remediation of contaminated soils and water, and sensing and detection of pollutants. These applications are directed towards environmental improvement and pollution control. 

The scientific content of green chemistry can be easily taken for the aims of IGN, whose main research topics are energy, green manufacture, life-cycle analysis, pollution prevention, food security, and chemical resources management. 

Green chemistry refers to practices designed to prevent pollution and promote the sustainable use of natural resources. 

The Pollution Prevention Act was passed to focus on preventing pollution at the source rather than dealing with remediation or capture of pollutants. This led the EPA to start its Green Chemistry Program in 1991. See this chapter, Section 7. 

One of the major themes in the Brundtland Report was a concept now known in green chemistry as atom economy (also sometimes known as atom utilization), the notion that chemical manufacturing should attempt to conserve as much of the raw materials (and, hence, atoms) with which it begins as possible and to prevent losing materials (and, hence, atoms) to the environment during manufacturing processes. 

Within a year of the act s adoption, the EPA had assigned responsibility for its implementation to the Office of Pollution Prevention and Toxics, formed in 1977 to administer the Toxic Substances Control Act, and had begun the first federally funded green chemistry programs. By 1992, the National Science Foundation had also begun funding research on "environmentally benign [chemical] syntheses and processes."... 

Green chemistry is an approach dealing with a fundamental environmental problem of the world, the problem of pollution. Pollution is usually defined as chemical pollution. Most often the approach utilized in the laws has been one of controlling the amount of release of a chemical or controlling the final concentration of that chemical in the medium to which it was released. Green chemistry deals with the above situation somewhat differently preventing the releases. 

The turn-of-the-century architect and planner Daniel Burnham is remembered for his famous quotation, Make no little plans they lack the fire to excite men s minds. Gender aside, Burnham was speaking for a revolutionary vision. The pollution prevention movement should more boldly state a vision and goals for the next century. The plans for green chemistry and green solvents are not little, and in the pages that follow we can readily see that the response of scientists has been great. 

Green chemistry seeks to reduce or eliminate the risk associated with chemical activity by reducing or eliminating the hazard side of the risk equation, thereby obviating the need for exposure controls and, more importantly, preventing environmental...
