Industrial growth is crucial for the development of countries. Leather industry is one of the major industries that generate significant income. However, the waste produced by these industries contains high concentrations of heavy metals, causing environmental and health impacts. Therefore, finding ways to reuse waste materials becomes a promising solution.
Industrial growth plays major role in development of countries. Among many industries leather is one of major industries generating higher income for countries. Waste generated from these industries is also higher and it is considered as a hazardous waste because of its higher concentration of heavy metals. Concentration of Cr(III) gets reacted with oxygen and converts into Cr(VI) which leads to many environmental impacts and health effects. They are disposed as a landfill, composting or anaerobic digestion processes, etc., also pollutes air, water and land. One of the promising budding technologies is reuse of waste material. This study is about the characteristics, effects and treatment of tannery sludge to make it reuse in concrete as replacement material. Hence comparative review is made on tannery sludge which researcher have already done.
