The invention relates to a method for purifying a contaminated solvent and concurrently producing a semi-finished product for use in the production of panels. The inventive method is characterized in that it comprises following steps: a) providing a first mass of fibrous material; b) softening at least part of a second mass of plastic material by impregnating it with a contaminated solvent adapted to at least partially dissolve said plastic material; c) mixing said fibrous material with the mass of softened plastic material to produce a compound; d) pressing said compound at a temperature that is at least equal to the melting temperature of said plastic material to obtain a semi-finished panel and a fraction of evaporated solvent.
La présente invention concerne une méthode de purification d'un solvant contaminé et de production concomitante d'un produit semi-fini pouvant être employé dans la production de panneaux. La méthode selon l'invention est caractérisée en ce qu'elle comprend les étapes suivantes consistant à : a) se munir d'une première masse de matériau fibreux; b) ramollir au moins une partie d'une seconde masse de matériau plastique en l'imprégnant d'un solvant contaminé adapté à la dissolution au moins partielle dudit matériau plastique; c) mélanger ledit matériau fibreux avec la masse de matériau plastique ramolli pour produire un composé; d) comprimer ledit composé à une température qui est au moins égale à la température de fusion dudit matériau plastique pour obtenir un panneau semi-fini et une fraction de solvant évaporé.
