| Popis: | Companies are interested in improving chemicals to reduce environmental impacts, also known as green chemistry. The 12 principles of green chemistry outline a framework for identifying a greener chemical or process, spanning aspects in health hazard, ecological risk, and resource efficiency across a product lifecycle. However, that framework does not detail how to measure performance. Furthermore, collecting the data required, beyond simple health hazard ratings, is resource intensive. This paper describes an approach for establishing green chemistry metrics (GCM), to evaluate chemicals and chemical processes against the 12 principles, using readily available data, such as the data compiled in compliance with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Using the GCM, chemicals or processes can be ranked by a hierarchy of metrics: (1) scores for each of the 12 principles, (2) three category rankings between new and improved chemicals/processes (improved resource use, i... |
