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.
