Title: Wastes from manufacture of dyes and pigments: Volume 1. Azo dyes and pigments (benzidine and its congeners subsector)

Technical Report ·
OSTI ID:6555439

In a study of the manufacture of dyes and pigments based on benzidine and its congeners, several solid waste streams that could contain hazardous material were identified. The solid residues included filter cake from clarifying operations, intermediates on discarded shipping containers, and fines collected in bag houses used in grinding and drying operations. An aqueous waste stream containing process wastewater and mother liquor that could contain hazardous material was also identified. Pigment manufacture represented the most important source of wastes because of its large volume relative to dyes. The emissions estimates showed 3,3'-dichlorobenzidine, o-dianisidine, and benzidine, were among the ten materials estimated to represent the major organic emissions from dye and pigment manufacture.
