A great deal of powder is needed to coat auto parts and other objects – and a great deal of waste is left over afterward: After all, only a fraction of the coating ends up on an autobody; the rest misses the target and is suctioned away. Recycling of residual powder has limits: If coaters mix in too much "recycled" powder, the quality of a coating suffers. Companies therefore dispose of most of the coating powder – an expensive undertaking. Grinding processes are similar: They also produce many residues and companies have to dig deep in their pockets to dispose of them.
