RECYCLING WASTE VEGETABLE OILS

With the increasing fast-paced consumption culture in the world, our resources are rapidly decreasing, and environmental pollution is increasing with the unconscious release of used products into nature. With the decrease in resources, the issue of raw material supply emerges as a serious problem. Among the products used, the most harmful products to the environment are the oils that we use both industrially and individually. Used waste oils must be recycled or disposed of in an environmentally friendly manner if they are not suitable for recycling. Unfortunately, 1 liter of waste vegetable oil damages exactly 1 million liters of drinking water, rendering it unusable. As a result of the mixing of waste vegetable oils with toxic properties into groundwater, clean water resources are polluted. Groundwater is a very important source of drinking water for all countries in the world. By reviewing the national and international literature on waste vegetable oils and their recycling, general and up-to-date information has been compiled, and this compilation study has been prepared by taking into account the current legal regulations. Throughout the study, it was aimed to raise awareness in order to leave a livable environment, a cleaner and healthier world for future generations, and some suggestions were developed and tried to be presented.
