Augmented demand for edible oil in the world has resulted in the founding of many edible oil industries leading to the generation of enormous amounts of pollutions including waste, wastewater, and air. These pollutants if release into the environment leads to serious problems including human health. The wastes of this industry are mainly bleaching earth and soap stock. The wastewater flow is caused by several processes such as decolorization, cooling towers, and boilers and air pollutants including volatile organic compounds (VOCs). This study is pointed to describe diverse methods expended by edible oil industries to treat waste, wastewater, and air pollutions and their effectiveness for elimination them.
