The role of waste compaction facility for reducing greenhouse gasses emission of waste transportation

Abstract

Waste sector contributes on greenhouse gasses (GHGs) including from waste transportation. As it significantly contributes to the total cost, municipality is most concerned on waste transportation. The paper aims to analyze the role of waste compaction facility to reduce the GHGs emission reduction. Through a sampling procedure for 8 consecutively days, total waste collected from the service area to the compaction facility was 122.35 m3 d-1 with waste density of 103.27 kg m-3. In order to transport all amount of waste to final disposal site located about 45 km from central of Bandung City, Indonesia it requires at least 8 trucks for 2 trips with waste density at truck of 200 kg m-3. Waste compaction results the increasing waste density up to 350 kg m-3. Thus, the truck required for waste transportation becomes 4 trucks. By assuming fuel efficiency of 5 km per litre of diesel and using emission factor published by DEFRA of UK (2.67 kg CO2 eq. per litre), it is found that total GHG emission reduction due to operational of waste compaction is 40% (from 720.9 into 432.54 kg CO2 eq. daily). In fact, the GHGs emission is reduced more when considering the traffic jam along way to final disposal site.
