GHG Emission from Trucks During Collection of Solid Wastes: Çorlu Case Study

Abstract

Kerbside collection is most common method in Turkey for solid waste collection. Çorlu has increasing population rate due to growing industrial activities and investments. Information used in the study such as; average waste collection amount in a month, truck properties (volume, engine power) and travelled distance during waste collection were obtained from Çorlu Municipality. Total fuel consumption of trucks during collection of 1-ton waste for      1-km is between 2.12-5.47 L diesel / ton in Çorlu. Greenhouse gas emissions for different scenarios were calculated in this study. First, GHG emission estimation done for same volume trucks using different fuel types, second estimation done for trucks with the same engine power using different fuel types. GHG emissions for Çorlu were calculated using emission coefficients for; diesel, gasoline, heavy oil, light oil, natural gas fuels from literature sources. Maximum emission is found as 35 kg CO₂-eq /ton, in case of using heavy oil in the 3.5 m³ vehicle and minimum emission is occurred  5,08 kg CO₂-eq while using natural gas in 13+1,5 m³ truck. Contrary to expectations, kg CO₂-eq / ton value (which is show the GHG emission rate) is decrease while the engine power (horsepower) increases. It has been determined that there are significant differences in GHG emissions when the truck and/or fuel type are changed, even without changing factors such as route, waste collection frequency and number of stops (number of containers).
