This Research Paper Explore the Review on Application of Bio Waste Materials on Adsorptive Removal of Azo dyes from Textile Effluents. Textile, paper, food, cosmetics, and pharmaceutical sectors all utilize synthetic dyes, with the textile industry being the major consumer. azo dyes are the most often used synthetic dyes in the textile industry, out of all the dyes available. Textile dyeing and finishing operations produce a lot of dye-containing wastewater, which is one of the major contributors of water pollution across the world. Several physico-chemical techniques have been used to treat textile wastewater, but these technologies have a number of drawbacks, including high costs, limited efficiency, and secondary contamination issues. Biological techniques, which include bacteria, fungus, yeast, algae, and plants, as well as their enzymes, have gained popularity as a cost-effective and environmentally acceptable alternative to physico-chemical processes. Biosorption or biodegradation are two ways that biological activities might decolorize azo dyes. Dye degradation may also be aided by a number of reductive and oxidative enzymes. This paper examines how biological processes decolorize and degrade azo dyes, demonstrating that microbial and plant cells are highly efficient biological weapons against poisonous azo dyes.
