Waste Cooking Oil Collection and Cafeteria Food Waste Management

Food premise refers to the cafeteria and restaurants which is a major contributor to water pollution. Contamination occurs due to the discharge of wastewater containing substances such as fats, oils and grease from the sink of the food premises into the drainage and irrigation system without passing through any separation process. The objectives of this study are to determine the level of waste cooking oil management in the cafeteria through the monitoring and data collection of waste cooking oil collection from the cafeterias; and to determine the level of water pollution as an indicator of pollution due to the cafeteria’s activities. The methods of collecting the weight of waste cooking oil produced from 18 cafeterias was recorded and analysed to obtain the total amount and average of weight for waste cooking oil collected. The result shown that there was an increment of used cooking oil collection as well as the active participation of the six cafeterias with a total accumulation of 1350 kg/year was successfully collected. This indicates to certain degree the effectiveness of the proposed collection system for the used cooking oil. The results of oil and grease contents for four sampling location were moderately high between 8.8 mg/L and 25.5 mg/L and this is an indicator to oil and grease pollution problems due to cooking activities and require a solution of oil and grease traps installed at each cafeteria.
