Method for recovering PVC and Alumina (Al2O3) from disposable Packaging for Medicines, Foods and beverages

摘要

In Colombia there is no deposits rich in Aluminum oxides. For this reason there is no need alu00famina.la Industry are imported from different countries like USA, Germany, Brazil and others. The volume of imports of this material is a little more than 2000 tons.According to the invention, aware of the High Generation of blister Packaging discarded in the pharmaceutical industry, began to recover the item Study Plastic (PVC) and the Aluminium content in them.The First, PVC, underwent a process of readitivaciu00f3n and pelletizing, for use in the Construction Industry (Manufacture of Tubes for Hydraulic installations, electrical and sanitary Construction, Profiles for doors and Windows, keep escobas. and aluminium, etc. Or, we transform it into alumina (A1203), as microabrasivos and nanoinsecticidas for Specialized uses.The First ophthalmic lenses, and for Polishing of Precious Stones and the second for Food Protection in silos and in Bulk Transport ships. The added value of a Calcined Alumina increases with a better and a technical process to reduce Particle sizes microM u00e9tricos and nano.
