Abstract

L’invention concerne un procédé de fabrication d’un objet décoratif (1) à partir d’au moins une première couche (C) d’un cordon extrudé à chaud d’une composition à base polymère, comportant une étape de passage d’une composition à base polymère dans une filière d’extrusion depuis une entrée d’alimentation en ladite composition jusqu’à une tête d’extrusion (51) de laquelle sort, en milieu ambiant, le cordon extrudé, la première couche (C) de cordon extrudé étant déposée sur un support de réception (20), caractérisé en ce que ledit procédé comprend les étapes consistant à : - utiliser une composition à base polymère consistant en du polyéthylène téréphtalate recyclé, ou un mélange de polyéthylène téréphtalate recyclé et de polyéthylène téréphtalate non recyclé, - chauffer la composition de sorte que la température du cordon extrudé, à la sortie de la tête d’extrusion (51), soit comprise entre 200°C et 300°C, - refroidir le support de réception (20) de manière à forcer le refroidissement de la première couche (C) de cordon extrudé par conduction, la température de refroidissement dudit support étant inférieure ou égale à la température du milieu ambiant.
