MCRC in collaboration with CSIR-CLRI has successfully demonstrated an alternative cleaner process for the recovery and reuse of chromium waste from tannery effluents using the spent microalgal biomass (SMB) from algal industry through the biosorption process. This eco-friendly process integrates two industrial wastes, SMB, an organic waste from algal industry and chromium waste from tannery to convert them to useful product viz., basic chromium sulphate, tanning material. This technological solution combats environmental pollution targeting “zero” discharge, which when adopted by cluster of tanneries largely situated in and around Ambur, Vaniyambadi, Ranipet belt of Tamil Nadu, will have immense positive impact on environment especially on the groundwater quality & other surface water resources in the villages / towns in these clusters and therefore, benefit the society.
