A process for forming particulate materials and binders into articles that are reusable after comminution, wherein the particulate materials are treated with a binder composition containing A) one or more copolymers containing one or more comonomer units selected from the group consisting of vinyl esters of branched or unbranched alkyl carboxylic acids of 1 to 18 carbon atoms; acrylic or methacrylic esters of branched or unbranched alcohols of 1 to 15 carbon atoms, dienes, olefins, vinyl aromatics and vinyl halides, and further containing 4 to 60% by weight, based on the total weight of the copolymer, of one or more comonomer units containing polar groups, and B) one or more fillers having a polar surface capable of interaction with the polar groups of copolymer A), and formed into articles and consolidated, and, if appropriate, the formed article obtained thereby is comminuted for recycling and the material obtained thereby is reused for forming new articles.
