Abstract
A process for converting viscous reactive chlorine- and sulfur-containing production residues into solid products which can be dumped, wherein the said residues are treated with alkaline materials. In a preferred embodiment of the invention, chlorine-containing and sulfur-containing production residues which are viscous and still reactive, e.g. the residues obtained from the manufacture of plant protection agents, dyes or fine chemicals, are converted in a simple and efficient manner into solid products which can be dumped. The treatment according to the invention has the advantage that no further pollution of the environment by waste gases or waste water results.
