How ‘Green’ Is Your Chemistry?

So, you believe your chemistry is green, only because of using ionic liquids or renewable feedstocks etc.? Of course, at least the latter is a good beginning, but there are also catalysts, auxiliary materials, coupled and by-products etc.. An overall mass balance helps to identify relevant weak points for optimization purposes and to enable a comparison to alternative procedures. Maybe (hopefully) you can (then) prove the advantage of your approach.
