These methods lead to the concept of «integrated biorefineries» where, from vegetable raw materials (whole plants, residues, microorganisms), different products are obtained and used for various industrial fields (food, biofuels, biomaterials, additives, pharmacy, enzymology, etc.).
The transformation of the whole plant by bioconversion processes has three advantages: it optimizes the energy yield per hectare; it limits the necessary surfaces and generates less waste. These advantages place the optimization of bio-conversion processes among the global technological priorities.
Pierre Guerin provides installations for producing biofuels & enzymes, ferments & food ingredients, biopesticides & biofertilizers, etc.
