Resumen

El creciente volumen de residuos plásticos en las regiones metropolitanas representa una amenaza ambiental y ecológica significativa, principalmente debido a la complejidad de las composiciones de polímeros mixtos que dificultan la clasificación y el reciclaje efectivos. Este estudio aborda este desafío clasificando manualmente los residuos plásticos posconsumo y recuperando polietileno (PE), polipropileno (PP) y poliestireno (PS) mediante un método de disolución-precipitación (SDP) basado en disolventes. Los polímeros extraídos se caracterizan mediante espectroscopia NIR, XRD, SEM, EDX y análisis termogravimétrico (TGA) para confirmar su pureza y estabilidad térmica. Los polímeros reciclados se fabrican posteriormente en membranas y se evalúa su rendimiento antibacteriano contra Escherichia coli. Entre las muestras, las membranas de PS exhiben la actividad antibacteriana más potente, reduciendo el crecimiento de colonias de E. coli con una zona de inhibición distintiva y medible (17 ± 0,76 mm), que se amplifica aún más en presencia de antibióticos (25 ± 1,52 mm). Esta investigación destaca una vía prometedora para convertir los residuos plásticos en membranas antibacterianas de alto valor para posibles aplicaciones, como la purificación del agua, lo que contribuye a los objetivos de la economía circular y la sostenibilidad ambiental.
