Characterization of Municipal Solid Waste (MSW) and Estimation of Greenhouse Gas Emissions at Bakung Site Landfill, Bandar Lampung City

Abstract

Municipal Solid Waste (MSW) which is disposed to unmanaged landfill site generates the large quantities of greenhouse gas (GHG) called landfill gas. This Landfill gas is composed from various type of gases, one of those gases is methane (CH4) that is 21 times more effective than carbon dioxide (CO2) which contributes to global warming. The number of methane gas generated from organic waste has different values depending on the waste characteristics. This study is aimed to calculate the GHG of Bakung landfill which is located at Bandar Lampung city by considering about the waste characterization using various analytical testing such as water, ash and carbon content which werethen use to calculate Degradable Organic Carbon or DOC (% wet weight). The percentage of DOC and the default data of IPCC Inventory software 2012 ver. 2.11 were then used to estimate emission rates for totallandfill gas.The software is based on the 2006 IPCC Guidelines for National Green House Gas inventories. The estimation calculation results showed that the Bakung landfill is able to generate an average of 2 665 m3 Million methane during 2018 – 2032.
