  • Publication number: 20240074363
    Abstract: The invention relates to a process for preparing a solid lignocellulosic material (1), referred to as a composite material, seeded with at least one organism (2), referred to as a filamentous fungus, which is a mycelium-forming multicellular eukaryote, in which: at least one solid lignocellulosic material (3) impregnated with an aqueous composition (5) is subjected to a treatment (6), known as a thermomechanical treatment, in which said at least one impregnated lignocellulosic material (3) is subjected to a succession of mechanical compression, expansion and shearing phases by blending at least one solid lignocellulosic material (4) of said at least one impregnated lignocellulosic material (3), in contact with the aqueous composition (5); said at least one impregnated lignocellulosic material (3) is brought to a temperature above 50° C.

  • Patent number: 11701804
    Abstract: A method for producing a part in the form of a solid block from a natural material in particulate form containing scleroproteins. A phase of heating the natural material, under compression at a pressure greater than or equal to 30 MPa, to a temperature greater than or equal to the denaturation temperature of the scleroproteins contained in the material. A phase of cooling the material thus obtained to a temperature less than 100° C., while maintaining the compression during at least a part of the cooling phase.

  • Publication number: 20230129744
    Abstract: A process for preparing a powder of a material of natural origin, which comprises a step of treating a substance containing at least 70% by weight of one or more leather wastes in particle form in a twin-screw extruder, wherein a temperature profile is applied that increases from an initial temperature of between 10 and 40° C. up to a maximum temperature of between 60 and 120° C., in the presence of water in an amount such that the weight ratio of water to said substance is between 0.20 and 6.

  • Publication number: 20150299751
    Abstract: A method of treating a solid lignocellulosic material (10) in which the solid lignocellulosic material (10) is subjected to a treatment, called a mechano-chemical treatment (1), of mixing and chemical degradation of the solid lignocellulosic material (10) so as to form an intermediate composition having a hydrated lignocellulosic material whose enzymatic digestibility is increased relative to the digestibility of the solid lignocellulosic starting material (10), then; the hydrated lignocellulosic material is subjected to a treatment, called a mechano-chemical treatment (2), in which a dispersion is formed, called an aqueous dispersion, of the hydrated lignocellulosic material (10) in an aqueous composition, the aqueous dispersion including at least one enzyme for degrading the hydrated lignocellulosic material (10).
