Abstract
A presente invenção refere-se a um método de despolimerização de uma carga de poliéster contendo PET, sendo que o dito método compreende, antes da etapa de despolimerização por glicólise e da etapa de purificação do efluente de despolimerização, uma etapa aprimorada de condicionamento da carga em que a carga de poliéster é condicionada em termos de temperatura e pressão e depois misturada a pelo menos um efluente de resíduos reciclado e a um efluente de diol com a finalidade particular de reduzir substancialmente a viscosidade da carga.
