Abstract

A method for recovering vinyl and urethane foam from composite plastic articles for recycling by granulating the article to form separated mixed components destaticizing the separate mixed components to prevent static during cling between foam particles and vinyl shell particles; and directing the destaticized particles through a vibrating fluidized bed to separate the vinyl shell particles and the foam particles.
