Abstract

Procedimiento para recuperar una matería plástica que se halla en cantidades preponderantes en desechos de materias plásticas tales como, sobre todo, desechos de frascos de materias plásticas usados, en el que se efectúa sucesivamente el desmenuzamiento de estos desechos, la separación de los desechos de papel no adheridos a estos desechos desmenuzados, la eliminación de los desechos de papel adherido a los desechos desmenuzados, por agitación de esos desechos en una solución acuosa de un álcali, y la recuperación de los desechos de la materia plástica a recuperar, por operaciones sucesivas de elutriación en medo líquido, caracterizado porque la solución acuosa de álcali se ajusta a una densidad tal que esta pueda ser igualmente explotada cuando la primera operación de elutriación en medio líquido.Process for recovering a plastic material found in predominant quantities in plastic waste such as, in particular, waste from used plastic bottles, in which the waste is successively shredded, the waste paper not adhering to the shredded waste is separated, the waste paper adhering to the shredded waste is removed by stirring the waste in an aqueous alkali solution, and the waste plastic to be recovered is recovered by successive elutriation operations in a liquid medium, characterized in that the aqueous alkali solution is adjusted to a density such that it can also be exploited during the first elutriation operation in a liquid medium.
