The chemical sector today begins a mutation from petrochemicals (petro-refinery) to agrochemicals (bio-refinery). Provided it does not compete with the food chain, agrochemicals offer original economic and ecological risk solutions, including reducing the carbon footprint and emissions of greenhouse gas emissions from finished products. Thus, alternative biomass is gradually integrating the chemical industry and in particular in the fuel sector. The challenge ahead is colossal; the aim is to produce bio-refinery by all the reaction intermediates and chemicals known to petrochemicals (mimicry), on the one hand, and to develop new molecules and bio-based materials, on the other hand.
