Procedimiento para la regeneración de residuos de pintura en polvo para dar pinturas en polvo reutilizables por medio de la compactación de los residuos de pintura en polvo, sin la fusión completa, para dar un producto aglomerado, caracterizado porque se compactan mezclas de residuos de pintura en polvo de diferentes tipos, o mezclas de residuos de pintura en polvo, con diferentes pinturas en polvo regulares, y los productos compactados obtenidos se muelen para dar pinturas en polvo, sin un tratamiento de extrusión. Process for working up powder coating waste to yield reusable powder coatings by compacting the powder coating waste without complete melting to yield a sintered product, in which process powder coating residues arising during powder coating production are continuously separated, continuously compacted and the compacted product is continuously ground together with fresh material to be ground of the same batch of powder coating without extrusion to yield a powder coating.
