Abstract

In this project of technological innovation, the intention is to have a blended polymer and an industrial process that permits the use of post-consumption rejects of PET and HDPE packaging, adding value to the re-cycled product, which will be in the form of PET/HDPE blends. The objective is to obtain a blend of PET/HDPE based on the use of these 100 per cent recycled polymers, or that is to say, previously used polymers so that this blend replaces in consumer products, other polymer materials that are used in virgin form. Also, there is the objective of other applications for the suggested recycled PET and HDPE such as injection processes, since currently the recycled PET is used exclusively in extrusion processes for the production of fibers and filaments, and the HDPE is used only in extrusion for the production of wrinkled plastic and tubes for packaging. The choice of PET/HDPE is due to their large availability in both weight and volume in garbage generated by the population. (AU)
