L'émergence d'une chimie doublement verte

Using a narrative approach, we describe the emergence of a « Doubly Green Chemistry » more as the product of a collective action in building a new sector, than an innovation breakthrough brought by individual actors. This action is initiated by the agricultural and agroindustrial firms that seek to substitute oil-based products by finding new uses of agricultural products. These actors have built « community?s productive patrimonies » by assembling knowledge bases and institutional resources. In order to mobilize their communities, they use the « rational myth » of plant cracking, later transformed into biorefinerie by integrating the principles of green chemistry, to make the technological changes sustainable.
