Resumen
El PET (tereftalato de polietileno) es uno de los polímeros termoplásticos más populares y utilizados en todo el mundo debido a su versatilidad, durabilidad y propiedades únicas, lo que le ha permitido ser ampliamente utilizado en varios ámbitos, siendo uno de ellos para fabricar envases y embalajes. Sin embargo, y derivado también de su amplio uso, el PET enfrenta grandes desafíos y problemas ambientales, desde su acumulación como un residuo hasta la falta de una cultura e infraestructura de reciclaje, lo que genera problemas ambientales. Este artículo presenta dos técnicas mecánicas como alternativas para darle un valor agregado al PET (tratamiento de desechos), primero, el electrospinning, del que se pueden obtener nanofibras con aplicaciones en diversas áreas; segundo, el spincoating, con la finalidad de obtener películas delgadas que pueden ser utilizadas como materia prima para otros productos. Se destacan los avances, ventajas y desafíos como el uso de solventes tóxicos, la necesidad de condiciones precisas y las limitaciones en la producción a gran escala, que aun con estos desafíos estas técnicas son una gran oportunidad para el aprovechamiento y reciclaje de plástico que no solo fomentan la sostenibilidad, sino que también abren nuevas oportunidades para el aprovechamiento de un residuo en aplicaciones industriales, dando un valor agregado a un residuo generado.
