Zusammenfassung:	The method for crushing elastomeric and thermoplastic solid matter in the form of parceled goods also in connection with another materials, comprises subjecting the parceled goods to extraction (2) with supercritical carbon dioxide and then subjecting subsequently to a shock wave treatment (4) with shock waves released through high voltage in fluid dielectric medium, where the medium is water, organic fluid with flash point temperature of below -20[deg] C or supercritical carbon dioxide. The shock wave treatment is carried out at -80[deg] C to +50[deg] C. The method for crushing elastomeric and thermoplastic solid matter in the form of parceled goods also in connection with another materials, comprises subjecting the parceled goods to extraction (2) with supercritical carbon dioxide and then subjecting subsequently to a shock wave treatment (4) with shock waves released through high voltage in fluid dielectric medium, where the medium is water, organic fluid with flash point temperature of below -20[deg] C or supercritical carbon dioxide. The shock wave treatment is carried out at -80[deg] C to +50[deg] C. The extracted materials (6) are recovered from extraction medium. The extract forms a fraction of the extracts or a pure material of a product obtained from the extract. The extraction medium and/or the dielectric medium are cleaned and/or restored. The extraction and/or the shock wave treatment are carried out directly to each other. A spontaneous relaxation takes place between the extraction and the shock wave treatment. The parceled goods are mechanically crushed before the extraction. The product of the shock wave treatment is subjected to further treatment. The further treatment comprises chemical functionalization of solid polymer from raw materials.
