Bauxite residue (Red mud) is an industrial waste byproduct of Alumina industry. It is very toxic and highly alkaline in nature and contains heavy metal oxides and variety of minor trace elements. Its disposal is the paramount environmental issue in Alumina refining processes and responsible for contamination of nearby forest soil, difficult to establish vegetation on red mud dumping sites. The bioremediation of Red Mud only seems to be a realistically convenient and suitable way for environmentally safe disposal of this toxic alkaline industrial waste residue. In an Indian Council of Forestry Research and Education, Dehradun sponsored research project, the bioremediation of red mud was carried out through Cyanobacteria and other bio-amendments. For study, M/s Hindalco Industries Ltd. (HINDALCo), India, was selected for study as it is the only Aluminium production industry functioning in Sonbhadra, Uttar Pradesh. Red Mud sample was analyzed for its physico-chemical characteristics. For Bioremediation studies, four Cyanobacteria species viz. Oscillatoria sp., Lyngbya sp., Phormidium sp. and Microcystis sp. were selected. These four Cyanobacteria species were subsequently cultured and propagated on liquid Blue Green Algae culturing medium BG-11 with different amendments of Red mud. Based on these, the physical growth of these Cyanobacteria in Red mud amended medium and their effect on physico-chemical characteristics of red mud, the promising cyanobacterial species were selected for bioremediation. Bioremediation through biomining/ bioleaching and nano particles is also discussed for reducing the environmental risk of red mud.
