The first general metric for green chemistry remains one of the most flexible and popular ones. Roger A. Sheldon’s environmental factor (E-factor) can be made as complex and thorough or as simple as desired and useful. [10] The E-factor of a process is the ratio of the mass of waste per mass of product:
If the Benchmark score is determined by the transformation products, the Benchmark score will include a subscript of TP. CoHC - Chemicals of High Concern (polymer residuals & catalysts): Version 1.4 of the GreenScreen added special rules for benchmarking polymers which include analysis of residual monomers and/or catalysts present at or above ...
Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]
The simplest definition was introduced by Barry Trost in 1991 and is equal to the ratio between the mass of desired product to the total mass of reactants, expressed as a percentage. The concept of atom economy (AE) and the idea of making it a primary criterion for improvement in chemistry, is a part of the green chemistry movement that was ...
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

The GreenScreen List Translator is a procedure for assessing chemical hazard used to identify chemicals of concern to prioritize for removal from product formulations. The List Translator assesses substances based on their presence on lists of chemicals associated with human and environmental health hazards issued by a global set of governmental and professional scientific bodies, such as the ...
Green Chemistry is a monthly peer-reviewed scientific journal covering every aspect of sustainable chemistry and its implementation in chemical engineering. It is published by the Royal Society of Chemistry and was established in 1999 by James Clark (University of York). Articles published in this journal are intended to be conceptually ...
Green engineering is a part of a larger push for sustainable practices in the creation of products such as chemical compounds. This movement is more widely known as green chemistry, and has been headed since 1991 by Paul Anastas and John C. Warner. Green chemistry, being older than green engineering, is a more researched field of study and ...
