Abstract
A process for working up powder lacquer wastes to give re-useable powder lacquers by compacting the powder lacquer wastes, without completely melting them, to give a sintered product, in which mixtures of different types of powder lacquer wastes or mixtures of powder lacquer wastes with different standard powder lacquers are compacted and the compacted products obtained are milled to give powder lacquers without an extrusion treatment.
