Estimating baseline CO2 emission from waste collection and transport activity to TPST Bantargebang, Jakarta

Abstract

Municipal solid waste is one of the fundamental problems in DKI Jakarta Province. The increasing population and various human activities had a direct effect on this issue. TPST Bantargebang served and treated all waste in DKI Jakarta Province, and the volume of waste generation reached 7,702 tons per day in 2019. Despite the waste generation, waste collection and transport are becoming emerging issues. The level of service by the Environmental Agency of DKI Jakarta Province is planned to reach 98% in 2025. Dump and waste trucks come and go in the long queue every day around TPST Bantargebang. This study estimated CO2 emissions from waste collection and transport activity using daily logbook data, fleet data, and spatial analysis. This study assigned the source point as a temporary disposal site in each subdistrict. It showed that the total vehicle kilometer traveled (VKT) reached 71,990.72 km/day, which collected and transported 5,897.67 tons of waste/day from 196 subdistricts. The need for fuel consumption reached 31,989.17 liters of bio-solar per day. The baseline of CO2 emission reached 70.805 tCO2 per day by multiplying the bio-solar emission factor and total fuel consumption. The CO2 emission per ton of waste transported reached 12 kg CO2 per day and the CO2 emission per kilometer of waste transported reached 0.98 kg CO2 per day.
