Abstract

Food service defines those businesses, institutions, and companies responsible for any meal prepared outside the home. This industry includes restaurants, school and hospital cafeterias, food court and catering operation. Two types of waste generated from food service are kitchen waste (KW) and food waste and food waste (FW). Food waste is foods that are discarded and lost uneaten. Kitchen waste is foods that are left over from cooking. Nowadays, food wasted has been increasing among Malaysians about 55% of solid waste disposed at landfills comprise of food. Malaysia also needs to produce its own feed ingredients for the poultry industry to remain self-sufficient while reducing dependency on imported agricultural products. In order to overcome this problem, an alternative has been developed to reduce this excessive of food waste and kitchen waste and to minimize the imported ingredients which are utilized these wastes as poultry feed. The study of this project is to determine daily kitchen waste and food waste generation at three different locations which are the cafeteria, food court, and restaurant in Serdang, Malaysia. In addition to analysing the proximate composition of food waste and kitchen waste and also produce a pelleting using the compaction process. Analysis of food waste and kitchen waste were determined by collecting all the waste, separated it into organic and inorganic waste. The sample of organic waste were boiled at 100⁰ for 30 minutes, dried in the oven at 55⁰ for 3 days and grinded into powder form. Then, the sample were analysed to determine the moisture content, protein, fiber, ash, fat and carbohydrate. The result shows that the food waste contains 56% of organic waste and 44% of inorganic waste while the kitchen waste contains 76% of organic waste and 24% of inorganic waste from three different locations. The food waste from the cafeteria is the most suitable to be utilized as poultry feed as their proximate composition similarly to bran. Finally, the pelleting process was done by the compaction process as well as the determination for physical properties of the pellets with different moisture content which are 40%, 50% and 60%. However, food waste pellets at 60% moisture content was better to utilize as poultry feed compared to kitchen waste pellets which are easily break into small pieces. Food waste pellets at 60% of moisture content give friability, bulk density, true density, porosity and tensile strength of 5.57%, 1447.53 kg/m^3, 289.85 kg/m^3, 79.03% and 3.06 kg/s respectively.
