Undoubtedly, leather industries are the key contributors in the economy of many developing countries. However, unfortunately these are also one of the major polluters worldwide, generating large volumes of high-strength wastewater having high pH, dark brown color, unpleasant odor, biological oxygen demand, chemical oxygen demand, total dissolved solids, and a blend of highly toxic environmental pollutants. It reduces sunlight penetration in aquatic resources which in turn decreases both photosynthetic activity and dissolved oxygen concentration affecting aquatic life; however, on land, it causes reduction in soil alkalinity and inhibition of seed germination. Moreover, it may also create serious toxicity in living beings upon exposure. Therefore, it becomes necessary to adequately treat/detoxify the tannery wastewater to protect the environment and living beings. Therefore, this chapter provides an overview on the environmental impacts, toxicity profile of tannery wastewater, and existing and emerging bioremediation strategies for environmental safety.
