The present invention is a method for the production of biofuel. The method includes providing a renewable, photosynthetically-produced biological material having at least one biofuel precursor and a cell-wall component. The photosynthetically-produced biological material is fractionated into at least two fractions, a first fraction enriched in the biofuel precursor and a second fraction enriched in the cell-wall component. The method includes the step of processing at least one of the second fraction and a product of its modification to generate thermal energy and further includes the step of processing at least one of said first fraction, a product if its modification, and a component of the first fraction to generate at least one biofuel. Processing of the first fraction includes at least one energy-consuming operation that consumes energy resulting from processing the second fraction. L'invention porte sur un procédé de production de biocombustible. Le procédé consiste à utiliser une substance biologique renouvelable, produite par photosynthèse possédant au moins un précurseur de biocombustible et un constituant de paroi cellulaire. La substance biologique produite par photosynthèse est fractionnée en au moins deux fractions, une première fraction enrichie dans le précurseur de biocombustible et une deuxième fraction enrichie dans le constituant de paroi cellulaire. Le procédé consiste à traiter la deuxième fraction ou un produit issu de sa modification pour générer de l'énergie thermique, puis à traiter la première fraction ou un produit issu de sa modification et un constituant de la première fraction pour générer au moins un biocombustible. Le traitement de la première fraction comprend au moins une opération qui consomme de l'énergie provenant du traitement de la deuxième fraction.
