Abstract

La présente invention se rapporte à un procédé amélioré permettant le recyclage de polystyrène expansé. Ledit procédé consiste essentiellement à réduire le volume d'un polystyrène expansé, par dissolution dans un solvant, séparation des composants insolubles, précipitation sélective du polystyrène à l'aide d'un anti¬solvant, séparation, séchage et extrusion du polystyrène précipité, récupération par distillation et recyclage du solvant. Le procédé selon l'invention est caractérisé en ce que l'anti-solvant utilisé est un butanol sélectionné parmi le n-butanol, l'isobutanol ou le sec-butanol, et le solvant utilisé est du carbonate de diméthyle, seul ou contenu dans un mélange renfermant jusqu'à 25 % de butanol.
