Method for processing packaging remnants with recovery of materials |
摘要 |
The invention concerns the method and apparatus for processing remnant-holding packagings while recovering substances of value, said method including the following steps: The packagings are inserted into an operational vessel 13, and the residues are extracted using a solvent. The residue-containing solution from the operational vessel 13 is transferred into a sump. The residue-holding solution is concentrated in the sump while the solvent is evaporated in an evaporation station 19. The evaporated solvent is condensed in a condensing station 20. The solvent is recycled from a recycling station 22 into the operational vessel 13. The residues are enriched and then recovered in concentrated form from the sump.
