Abstract
A process for separating and recovering waste carpet material components, especially face fiber material, includes removing adhesive material from the waste carpet material feedstock to obtain a mixture containing face fiber material which is passed with a liquid medium to a hydrocyclone, where the solids in the mixture are separated on the basis of specific gravity, and recovered. The recovered components can then be processed into desired products.
