A process for reclaiming residuals produced from the manufacture of decorative high pressure laminates (HPLs), and composite materials obtained by the process. Such residuals which include cellulose impregnated with thermosetting resins which are partially condensed, are ground to a predetermined particle size and mixed with a melted mass of thermoplastic resin under controlled pressure and temperature conditions. The mixing time is sufficiently long for completion of the reaction during which physical and chemical interactions occur between the partially polycondensed thermosetting resin and the thermoplastic resin. The material so produced can be converted into granules for subsequent injection molding. There is provided an effective solution to pollution problems and excessive expense problems associated with the disposal of scraps and residuals from the manufacture of decorative HPLs.
