Análisis del ciclo de vida del reciclado del polietileno de alta densidad

Abstract

Los termoplásticos constituyen aproximadamente el 80% de los plásticos producidos hoy en día. Actualmente existen muchos tipos de termoplásticos. No obstante, se siguen desarrollando nuevos tipos. Sin embargo, no todos los termoplásticos se reciclan en igual proporción. Los que más comúnmente se reciclan son el polietileno (PE), el polipropileno (PP), el poliestireno (PS) y el cloruro de polivinilo (PVC). En este estudio, se han utilizado datos reales de una industria dedicada al reciclaje de plásticos para realizar el análisis del impacto ambiental a través de la aplicación de la metodología del Análisis del Ciclo de Vida (ACV) de los productos y procesos que intervienen en el reciclaje mecánico de polietileno de alta densidad (PEAD) negro, para la extrusión o soplado procedentes de residuos industriales. Los resultados obtenidos se han comparado con otros análisis realizados por otros autores y con impacto medioambiental asociado a la fabricación de termoplástico virgen procedentes de bases de datos. Al interpretar estas comparaciones, se puede concluir que el proceso de reciclaje se ha optimizado en los últimos años, lo que reduce su impacto ambiental, además de destacar las claras ventajas desde el punto de vista de la eficiencia ecológica de reciclaje de plástico frente a la fabricación directa de petróleo

Thermoplastics make up roughly 80% of the plastics produced today. There are hundreds of types of them and new variations are being developed. But not all thermoplastics are recyclable in the same proportion. The most commonly recycled thermoplastics are polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). In this study, real data from the industry is used in the analysis of the environmental impact of plastics recycling by means of the application of the Life Cycle Assessment (LCA) methodology to the products and processes involved in mechanical plastic recycling of black high density polyethylene (HDPE) for extrusion or blow moulding coming from industrial scrap. The results obtained were compared with assessments made by other authors and with the impact associated with the manufacturing of virgin thermoplastic according to databases. The interpretation of these comparisons leads us to conclude that the recycling process has been optimised over the past years, thus reducing its environmental impact. Furthermore, the clear advantages from the eco-efficiency viewpoint of plastic recycling against direct manufacturing from petroleum are highlighted
