A process for manufacturing rubber crumb comprises the following steps: (a) suspending rubber granules having a given size in an autoclave () containing a supercritical fluid; (b) agitating the mixture for a predetermined time at constant pressure and constant temperature; (c) carrying out an isenthalpic expansion of the mixture from step (b) by spraying it through a nozzle ().

The invention concerns a method for preparing compounds for interaction of an active substance hardly soluble in an aqueous medium with a porous support. The invention is characterized in that it comprises the following steps: (a) mixing the active substance generated by supercritical fluid and the specific amount of porous support; (b) carrying out a molecular diffusion step by contacting in static mode a supercritical fluid with the mixture obtained at step (a) for the time required to improve the dissolution in the aqueous medium of the mixture obtained at step (a); (c) washing the interactive compound obtained at step (b) with a supercritical fluid flow; (d) recuperating the particles of the interactive compound thus formed. The invention also concerns a compound obtainable by said method.

The present invention concerns a process for treating bone tissue of animal or human origin, and a corresponding implantable biomaterial. According to the present invention, a fluid in the supercritical state is caused to penetrate throughout the bone tissue. The bone tissue thus treated can then undergo stages of extracting specific proteins. This tissue is intended to be placed on a damaged bone tissue and has mechanical properties at least equivalent to those of natural bone.

The invention concerns the use with the aim of antiviral prophylaxis of a current of carbon dioxide CO.sub.2 in the supercritical state in contact with a tissue having a collagenous network of human or animal origin intended to be used as or in an implantable supporting tissue prosthesis as a biomaterial, wherein carbon dioxide in the supercritical state has the function of eliminating viral contamination from the tissue.
