CABON DIOXIDE EMISSION FROM SOLID WASTE DISPOSAL OF NAN MUNOCIPALITY

Abstract

A study of carbon dioxide gas (CO2) emission from solid waste disposal of Nan Municipal. The study relied on primary and secondary data, including existing waste management and waste generation rate in 2019 to analyze waste composition and CO2 emission from landfill disposal. The evaluation of carbon dioxide emission was calculated from emission factors (EF) in term of CO2 equivalent according to the guidelines of The Intergovernmental Panel on Climate Change (IPCC) and Thailand Greenhouse Gas Management Organization (Public Organization) (TGO). The result of the study showed that food waste represents the largest portion in the waste stream (46.23%), followed by plastic (24.11%) and paper (14.56%). The solid waste disposal of Nan Municipality generated a total of 16,487.71 kgCO2 eq per year. CO2 emissions from each type of solid waste landfill 16,405.28 kgCO2 eq per year and vehicle fuel used for landfill waste 82.43 kgCO2 eq per year. Therefore, in order to reduce greenhouse gas emissions, solid waste separation and the appropriate technique for disposal should be used such as reuse or recycle.
