Estimating backyard waste burning emission: A case study of Tembalang Campus, Diponegoro University

Abstract

Abstract This study analyzes the distribution and amount of CO, CO2, HC, and NOx gas emissions resulting from the open burning of backyard waste in Diponegoro University. The burned waste sample is taken from surrounding environment of Diponegoro University (Tembalang Campus) by taking 4 random samples (3 kg each). Emissions from CO, CO2, HC, and NOx gases were obtained from the 24 minutes combustion test. Furthermore, the gaseous pollutant emitted is measured using a gas analyzer. The burned waste comprised 73.77% of organic waste, 17.45% of plastic; 4.33% of paper; and 4.45% of other waste. The emission test results show that the highest CO, CO2, HC, and NOx emissions have occurred at 14, 20, 18, and 18 minutes, respectively. The combustion test reveals that an enormous amount of CO, CO2, HC, and NOx gas is emitted during uncontrolled waste burning. Because backyard wastes burning produce significant gaseous pollutants, several efforts are needed to reduce this practice.
