A decision matrix was used to create two single value metrics for each polymer, one evaluating each polymer for life cycle environmental impacts and the other evaluating each polymer for adherence to green design principles. Results from both assessments were normalized to the average across aU polymers, shown in Eq. (15.3), where N- is the normalized value for polymer i in metric/impactj, V- is the...

Mass index (MI) is defined as the total mass used in a process/process step divided by the mass of product and it is approximately the E-factor plus one. A software package, the Environmental Assessment Tool for Organic Syntheses (EATOS), has been designed to calculate some of these metrics. More elaborate assessments such as life cycle assessment (LCA), could be performed, but this is also beyond the scope of this chapter. Our objective is to provide a preliminary assessment for the community to determine if further development of any guanidine organocatalysis is appropriate for use in green chemistry.
