This guideline deals not only with the disposal of used and unusable coolants and cutting fluids (metalworking fluids) but also with residues containing these substances, approaching this from the points of view of universal process application, consideration of the latest developments in engineering, and compliance with currently applicable legal instruments (statutes, ordinances, regulations) and with the aim of obtaining waste matter which can be recycled. Detailed information about metalworking fluids for cutting and reshaping manufacturing processes may be found in VDI 3397 Part 1.
