Solid waste disposal from small and medium scale industries including leather sector, which are classified under hazardous category, has become a matter of increasing concern. The disposal of 200,000 tons of dewatered hazardous category sludge generated annually from 200 Effluent Treatment Plants (ETPs) and 17 Common Effluent Treatment Plants (CETPs) is one of the serious problems in India. More than 80% of the tanneries adopt chrome-tanning practice. In traditional chrome tanning practice only 50-60% of the chromium applied is taken by the leather and the balance is discharged as waste. South Asian tanneries use annually 200,000 tons of chromium in the form of Basic Chromium Sulfate (BCS) and out of this about 80,000 tons of chromium salts are discharged as waste. With a view to minimize the disposal problem of sludge, an appropriate, simple and fully operational commercial scale chrome recovery and reuse system was developed and promoted in India and other South Asian countries. Due to the reduction in chromium concentration from the level of 2 to 3% to less than 0.5% as Cr, the sludge is classified as non-hazardous category as per the Ministry of Environment & Forests (MoEF). This paper deals with the simple and viable land disposal methods developed and adopted in India at commercial scale for hazardous category as well as for non-hazardous category sludge and solid wastes.
