Abstract

L’invention concerne un procédé de dépolymérisation d’une charge polyester comprenant du PET, ledit procédé comprenant, préalablement à l’étape de dépolymérisation par glycolyse et aux étape de purification de l’effluent de dépolymérisation, une étape améliorée de conditionnement de la charge dans laquelle la charge polyester est conditionnée en température et pression puis mélangée à un effluent diol dans un mélangeur statique ou dynamique afin notamment de réduire sensiblement la viscosité de la charge.
