  • Process for preparing a powder of material of natural origin
    Patent number: 12351691
    Abstract: A process for preparing a powder of a material of natural origin, which includes 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 substance is between 0.20 and 6.

  • Method for producing a part from a particulate natural material and part obtained by such a method
    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.
