Study of Generation, Composition, Characteristics, and Recycling Potential of Industrial Food Waste in Padang City

Abstract

The purpose of research to measure and analyze the generation, composition, characteristics, and potential recycling industrial food waste in Padang City. The sampling and determination of samples based on SNI 19-3964-1994, which was carried out for eight consecutive days with sampling from 35 food industry consist of large industrial, medium industries, and small industries. The average quantities of food waste generated from the large, medium, and small industries in Padang City were 0.005 kg/d, 0.083 kg/d, and 0.262 kg/d, respectively. The composition of food waste consists of 94.01% organic waste, 5.97% plastic waste, 0.01% paper waste, and 0.01% other waste. The potential for recycling of industrial food waste was 75.20% plastic, 100% nonferrous metal, and 97.38% organic waste. The characteristics of the waste based on parameters average density, water content, volatile content, ash content, fixed carbon, C/N ratio, calorific value, and biodegradability fraction were 13.32 kg/l, 13.77%, 26.75%, 45.39%, 14.09%, 13.77, 1,798 kJ/kg, 38.87%, respectively. The generation, composition, characteristics, and potential recycling industrial food waste is very important for proper waste management.
