Method for recycling a mixture of particles resulting from a method for cutting by abrasive wire, comprising the following successive steps: - providing a mixture comprising first particles of a first material and second particles of a biodegradable polymer material soluble in a solvent, obtained according to a method for cutting a part made from the first material with abrasive wire, comprising the following successive steps: - securing the part to be cut, made from the first material, the first material being silicon, on a sacrificial support made from a biodegradable polymer material soluble in a solvent; - cutting the part with the abrasive wire, preferably a diamond wire, the cutting being implemented until the sacrificial support is notched, by means of which a thin slice of a first material and a mixture comprising first particles of the first material and second particles of the biodegradable polymer material are obtained; - adding to the mixture solvent able to dissolve the second particles of biodegradable material, by means of which a solid phase formed by the first particles made from the first material and a liquid phase comprising the solvent in which the biodegradable polymer material is dissolved are obtained, - separating the solid phase from the liquid phase, in particular by a centrifugation or filtration step, by means of which a powder of particles of the first material is obtained. - providing a mixture comprising first particles of a first material and second particles of a biodegradable polymer material soluble in a solvent, obtained according to a method for cutting a part made from the first material with abrasive wire, comprising the following successive steps: - securing the part to be cut, made from the first material, the first material being silicon, on a sacrificial support made from a biodegradable polymer material soluble in a solvent; - cutting the part with the abrasive wire, preferably a diamond wire, the cutting being implemented until the sacrificial support is notched, by means of which a thin slice of a first material and a mixture comprising first particles of the first material and second particles of the biodegradable polymer material are obtained; - securing the part to be cut, made from the first material, the first material being silicon, on a sacrificial support made from a biodegradable polymer material soluble in a solvent; - cutting the part with the abrasive wire, preferably a diamond wire, the cutting being implemented until the sacrificial support is notched, by means of which a thin slice of a first material and a mixture comprising first particles of the first material and second particles of the biodegradable polymer material are obtained; - adding to the mixture solvent able to dissolve the second particles of biodegradable material, by means of which a solid phase formed by the first particles made from the first material and a liquid phase comprising the solvent in which the biodegradable polymer material is dissolved are obtained, - separating the solid phase from the liquid phase, in particular by a centrifugation or filtration step, by means of which a powder of particles of the first material is obtained.
