| Summary: | At present, the production and consumption of plastics, specifically those of single use, has been a mostly environmental problem due to the enormous generation of waste of this type and the limited response in the mechanisms of collection, storage, transformation and management of the same, forcing this to develop different processes to return as much plastic waste as possible to a circular economy generating new raw material to integrate into new production processes.
The main purpose of this article is to carry out a review and presentation of the most relevant aspects that allow defining a possible viability to develop studies, research, processes and subsequent tests and analysis of results, punctually in the process of transformation of recycled waste of thermoplastic polyethylene terephthalate (RPET) used as a polymeric structural matrix with an addition of aluminum silicate as a charge by the compounding process.
First, figures are presented at the global and regional level of production and generation of plastic waste as a fundamental problem, then the potential in the management and collection of plastic waste in the country and specifically in the cities of Pereira and Dosquebradas (Risaralda – Col.) is reviewed. Then, the fundamental physicochemical and structural characteristics of post-consumer recovered polyethylene terephthalate (RPET) and aluminum silicate are presented, and the complete description of the compounding process and generation of polymer matrix composites and modified nanoclay loading and in addition, the status and results of the tests and trials carried out in recent years on composite materials of polymer matrix and nanoclay load and their respective characterization mainly of their mechanical properties is reviewed.
Finally, the materialization of the project that is currently in the state of advanced execution in the Center for Industrial Design and Technological Innovation (CDITI) – SENA is presented as a research project of the SENNOVA research system, in which the entire process of recovery and mechanical treatment of PET is developed, it is pelletized as a PET matrix material with aluminum silicate obtained in the compounding process, to later manufacture specimens for mechanical tests and the results of these will be analyzed to characterize the rheological and mechanical properties of the new composite material. |
