History[ edit ] Green chemistry emerged from a variety of existing ideas and research efforts such as atom economy and catalysis in the period leading up to the s, in the context of increasing attention to problems of chemical pollution and resource depletion.

The development of green chemistry in Europe and the United States was linked to a shift in environmental problem-solving strategies: The set of concepts now recognized as green chemistry coalesced in the mid- to lates, along with broader adoption of the term which prevailed over competing terms such as "clean" and "sustainable" chemistry.

At the same time in the United Kingdom, researchers at the University of York contributed to the establishment of the Green Chemistry Network within the Royal Society of Chemistryand the launch of the journal Green Chemistry. Warner then of Polaroid Corporation published a set of principles to guide the practice of green chemistry.

The principles cover such concepts as: The twelve principles of green chemistry are: Preventing waste is better than treating or cleaning up waste after it is created.

Synthetic methods should try to maximize the incorporation of all materials used in the process into the final product. Less hazardous chemical syntheses. Chemical products should be designed to achieve their desired function while being as non-toxic as possible. Safer solvents and auxiliaries.

Auxiliary substances should be avoided wherever possible, and as non-hazardous as possible when they must be used. Design for energy efficiency.

Energy requirements should be minimized, and processes should be conducted at ambient temperature and pressure whenever possible. Use of renewable feedstocks. Whenever it is practical to do so, renewable feedstocks or raw materials are preferable to non-renewable ones.

Unnecessary generation of derivatives—such as the use of protecting group s—should be minimized or avoided if possible; such steps require additional reagents and may generate additional waste. Catalytic reagents that can be used in small quantities to repeat a reaction are superior to stoichiometric reagents ones that are consumed in a reaction.

Chemical products should be designed so that they do not pollute the environment; when their function is complete, they should break down into non-harmful products. Real-time analysis for pollution prevention. Analytical methodologies need to be further developed to permit real-time, in-process monitoring and control before hazardous substances form.

Inherently safer chemistry for accident prevention.

Material Information

Whenever possible, the substances in a process, and the forms of those substances, should be chosen to minimize risks such as explosions, fires, and accidental releases.House report on ENERGY RESEARCH, DEVELOPMENT, DEMONSTRATION, AND COMMERCIAL APPLICATION ACT OF This report is by the Science.

The growing field of green and sustainable chemistry seeks to address this through the development of products and processes that are environmentally benign while remaining economically viable.  Inorganic chemistry plays a critical role in this endeavor in areas such as resource extraction and isolation, renewable energy, catalytic.
