Resumen

La espuma rígida de Poliuretano es un material sintético que se genera mediante la reacción entre un poliol y un isocianato, que cuenta con excelentes propiedades termoaislantes; sus aplicaciones generan un residuo, el cual es considerado en Colombia, como un residuo peligroso. Por tal motivo, el presente artículo consiste en una revisión bibliográfica sobre las diferentes metodologías de reciclaje aplicados para el residuo de espuma rígida de poliuretano (PUR). Se expondrán alternativas desde el ámbito de reciclaje químico, mecánico y de recuperación de energía o térmicos, incluyendo además tratamientos de índole biológico. A partir de los reportes de la literatura se evidencia que el reciclaje mecánico se destaca por su simple aplicación y bajos costos. Por otro lado, el tratamiento químico ofrece más alternativas para la incorporación de ciertos productos a líneas de producción; sin embargo, se dificulta la alta tecnología necesaria para su aplicación. Situación similar a los tratamientos biológicos, cuyo ciclo de vida de los microorganismos es fundamental para su aplicación.  Mientras la recuperación de energía o tratamientos térmicos presentan una buena oportunidad de energía sostenible, no obstante, sus emisiones son un factor a vigilar. Todas las alternativas de reciclaje permiten generar una economía circular sostenible en el tiempo, disminuyendo el impacto negativo del residuo sobre la salud de las personas y el medio ambiente.
