Waste cooking oil (WCO) is the bio-based material produced from renewable feedstock and emerged as a major issue in waste management. It is generated in huge amount in large scale all over the world. Human health is greatly affected by the negative impact of unreasonable deposition of WCO which is imparted in the environment.
A large amount of animal fats and waste cooking oils is produced by developing countries. India has a population of over a billion people generate organic waste and used cooking oil every day. Cooking oil generated in huge quantities from large restaurants, cafeterias, fast-food networks and dining rooms etc. Disposal of waste cooking oil causes environmental damages due to which oily films form over aquatic surfaces, which causes the disturbance in oxygen diffusion and clogging (organic matter emulsification). Degradation of waste cooking oil is a major challenge because it contaminates land and water resources. Some of the percentages of waste cooking oil are used as additives in domestic animals feedstock and soap preparation etc. but a major part of it is discharged into rivers, drainage system and landfills causing environmental pollution.
Vegetable oils and fats are mixtures of triacylglycerols which is composed of fatty acids and glycerol. Vegetable oil spills are becoming frequent and more challenging nowadays.
