Future trends in green chemistry ppt
About Trends in Green Chemistry Green Chemistry is a New trend or buzz word to design safer chemicals and processes. It minimizes the negative impact of chemicals on the environment and helps in achieving sustainability in the chemical production. Green Chemistry and Green Engineering is the "New Philosophy" in research, development and manufacturing for new products. The golas are to use effieciently natural resources and energy, to reduce design for reduced hazard. Some industry reports predict green chemistry as the future of all chemistry. II. HISTORY Green chemistry is built upon advances in areas and disciplines that existed prior to the field’s inception including catalysis, atom-economical synthesis, degradable materials, and alternative solvents. When green chemistry was founded in the early 1990s, there Chemistry advances on two feet: one is utility, one curios-. ity. A prediction of its future path can only be a guess, based on its past progress and its present position. The most inter- esting and important directions to come-those that repre- sent radical departures from the present-I cannot predict.
Future Trends in Green Chemistry VOC reduction enables better indoor and outdoor air quality, and decreases human exposure to pollutants, Dow’s low-or no-VOC solutions cost less than more traditional compounds, Dow’s low or no-VOC solutions meet sustainability requirements without compromising the quality of the product.The manufacture of computer chips requires excessive amounts of chemicals, water, and energy.
There is a plethora of achievements in the fields of “green chemistry” (3, 4) and “green engineering” that have demonstrated that more performance and functionality from our chemical products and processes can be realized while decreasing adverse impacts. These successes need to be made systematic and not anecdotal. Developing new green solvents in designing chemical products and processes or successfully employing the already existing ones is one of the key subjects in green chemistry and is especially lyst waste in this step is an important development in the pursuit and application of green chemistry. In the overall process 6 stoi- chiometric steps with <40% atom utilisation have been replaced by 3 catalytic steps with ca.80% atom utilisation. To illustrate the state of the art in the use of enzymes and microorganisms, representative examples of industrial chemistry are discussed and evaluated in this article. Several biocatalytic processes are compared to their chemical alternatives. Finally, future trends for the biocatalytic reductions of amides and Presidential Green Chemistry Challenge The Presidential Green Chemistry Challenge was established to recognize and promote fundamental and innovative chemical technologies that accomplish pollution prevention through source reduction and that are useful to industry.

Title: Green Chemistry for a Sustainable Future 1 Green Chemistry for a Sustainable Future. Chapter 20; 2 20.1 Introduction. The beginning of the chemical industry dates back to approximately 1850. Since then it has arguably grown to become the most significant segment of the anthrosphere. 3 20.1.
