The leather processing industry is a major pollutant due to use of toxic chemicals like sulphides and chromium salts. At Kanpur, one of the major leather tanning centres of India, the effluents were flowing into and polluting the Ganga. Now, a combined effluent treatment plant diverts the waste water from the tanneries, and treats it alongwith domestic sewage water. But efforts are still required to motivate individual tannery owners to set up chrome recovery plants for the treatment process to be truly effective.
