Abstract

La presente invención se refiere a un proceso para despolimerizar una carga de poliéster que comprende PET, que comprende tal proceso, antes de la etapa de despolimerización por glucólisis y las etapas de purificación del efluente de despolimerización, una etapa mejorada de acondicionamiento de la carga en la cual se acondiciona la carga de poliéster en temperatura y presión y luego se mezcla con al menos un efluente de residuo reciclado y un efluente de diol para en particular reducir sustancialmente la viscosidad de la carga.
