Résumé
With the depletion of fossil fuel on earth, the logical alternative to replace fossil carbon for chemistry is renewable carbon from plants biomass. Scientists present green chemistry as the new paradigm of chemistry, which will help meet the challenges of sustainable development. We discuss this hypothesis by observing practices in doubly green chemistry (2GC) research programs. 2GC becomes a dominant principle in green chemistry as the 7th of the 12 principles of GC advises using renewable vs fossil carbon material; but using renewable carbon it is not enough to guarantee sustainability. After highlighting the fact that we must study green chemistry as an institutional construct rather than a paradigm, we have apprehended chemistry as a discipline of oriented learning, scientists seeking to connect to "productive heritages" (PH). We have identified a variety in C2V organized around collective productive and scientific heritage, some of which refuse to borrow the metaphor of refinery cracking, by using limited biomass fractionation.
