Inspection of the complete ACS GCI guide reveals in general there are very few red (i.e., ungreen) scores [54], a fact that is repeated in Fig. 253334, 1996. None of the suggested unconventional dipolar aprotic solvent have nitrogen or sulphur atoms that would result in NOx and SOx air pollution when incinerated. Moreover, the pharmaceutical entities and food industry products do not tolerate a contamination, of even traces, of any such metals for that matter. I. R.

Some of the examples include bioderived and biodegradable organocatalysts. 573575, 2001.
