Waste Recycling in Biaxially Oriented Polypropylene - BOPP

摘要

Over time the production of the packaging has grown, incorporating new functions. One of the most found types of packaging in supermarkets is those of Biaxially Oriented Polypropylene (BOPP). This project aims at the recycling and characterization of wastes in Biaxially Oriented Polypropylene, for its recycling. The search seeks to select a problem with a practical goal. The question raised concerns the possibility of characterization and recycling of waste. Through the collection of BOPP packaging, the evaluation of the potentiality of recycling the waste was idealized, establishing a form of the polymer mixture, to obtain a homogeneous mass. They were specifically intended to evaluate the different formulations through essays, to define the best composition, by compounding their properties and checking their possible applications. The theoretical reference focused on the studies on the packaging and the BOPP. The process of metalization of the packaging consists of the combination of a thin layer of aluminium to the plastic film using steam. The methodology consisted of the collection of the material, its separation, and cleanliness. The mixture was made from BOPP and polypropylene (PP) recycled. Formulations made to define the best composition of the material content passed in the extruder. As a result, the combination of the two waste was not possible, because the granulation of the BOPP was not adequate compared to the PP. For the project to be appropriate, it would be necessary to use a binder machine to reduce the volume of BOPP waste.
