Green Chemistry Definitions

By definition all catalysts must be heterogeneous or homogeneous within and across these two categories there are other classifications that are important to green chemistry. Most important among these are ... 

The advantages to using MSDSs for chemical inventories are that MSDSs are publicly available and required by law. There is no extra cost or labour needed to supply them. The limitations to using MSDSs as a source of inventory data are that currently, in the United States, a standardized reporting format is not mandatory. MSDSs are not verified or audited and MSDS information can be incomplete and/or inaccurate. In addition, OSHA s definition of hazard does not include the broader scope of hazard used in green chemistry. Therefore, chemicals that are potential hazards from the green chemistry perspective but are not defined by OSHA as hazards, are not required to be identified on a MSDS. 

A common definition of green chemistry, which clearly encompasses considerable chemical engineering as well, is the design, development and implementation of chemical processes and products to reduce or eliminate substances hazardous to human health and the environment, (P. T. Anastas and J. Warner, Green Chemistry Theory and Practice, Oxford University Press, Oxford, 1998). A more recent article expands this definition to twelve principles (M. Poliakoff, J. M. Fitzpatrick, T.R. Farren and P.T. Anastas, Science, 297, 807-810 (2002). 

Because RME accounts for the mass of all reactants, that is, the actual stoichiometric quantities used, and therefore includes yield and atom economy, this combined metric is probably one of the most helpful metrics for chemists to focus attention on how far from green their current processes actually is. However, like many green chemistry metrics, it does take a little bit of thought to calculate in practice, as one has to work to strict definitions of what to include and what to exclude [46] ... 

The American Chemical Society, http //www.acs.org/education/greenchemis-try. ACS uses definition based on Anastas, P.T. Warner, J.C. Green Chemistry Theory and Practice, Oxford University Press New York, 1998, p.30. (By permission of Oxford University Press.)... 

Green chemistry is also known as environmentally benign chemistry, or sustainable chemistry. Perhaps the most widely accepted definition of green chemistry is the one offered by chemists Paul Anastas and John Warner, who defined green chemistry as the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. 

The 12 principles of green chemistry were developed by Paul Anastas and John C. Warner to help explain what the definition means in practice.110 The principles cover such concepts as... 

It is now conventional wisdom to point out that chemical engineering is rapidly spreading into new technical areas described by such words as electronic materials, green chemistry, ecology, smart materials, drug-delivery systems, etc., etc., and above all, biotechnology. Because it is so difficult to give a contemporary definition of... 

A reasonable working definition of green chemistry can be formulated as follows [10] Green chemistry efficiently utilizes (preferably renewable) raw materials, eliminates waste and avoids the use of toxic and/or hazardous reagents and solvents in the manufacture and application of chemical products. 

The third component to many tenure and promotion decisions is often referred to as service . This has many definitions and is generally split into service for the college and service to the outside community. Green chemistry is being utilized as a way for chemists to reach out to the community in a positive way and to involve students in service learning type projects. Expansion of green chemistry into the K-12 curriculum has been fostered by outreach programs developed by many people. 

The most widely accepted definition of green chemistry is the design, development and implementation of chemical processes and products to reduce or eliminate substances hazardous to human health and the environment . This definition has been expanded into 12 Principles of Green Chemistry 1... 

The scope of the ASI fits the definition of NATO Priority Research Topics as Environmental Security that can be defined as the relative public safety from environmental dangers caused by natural or human processes due to ignorance, accident, mismanagement or design and originating within or across national borders. From this standpoint, the objectives of Green Chemistry are indeed aimed to minimize the environmental concerns caused, inter alia, by many human activities.
