Comparing Greenhouse Gas Emissions from Municipal Solid Waste Management Scenarios: A case of Palembang, Indonesia

The waste sector is one of the largest contributors to greenhouse gas (GHG) emissions in Indonesia. Landfilling (without methane recovery) and open burning solid contribute significantly GHG emissions. This study analyses magnitude from various municipal management (MSW) alternatives Palembang city. estimation was conducted for five scenarios, i.e. (a) BAU scenario (existing) where 850.12 tonnes MSW disposed semi-aerobic landfill (not well managed), 37.73% incinerators, 1.17% 3R facilities, 61.1% others; (b) Scenario 1, which upgraded a (well managed); (c) 3, 70% managed) 30% facilities; (e) 4, all collected treated incinerators. methodology estimating used IPCC 2006 (revised 2019). Emission Quantification Tool IGES calculate collection, transportation, composting, recycling/upcycling, final disposal (landfill or incineration). projected up year 2030, accordance with Indonesian NDC. result analysis shows that existing condition (BAU) has highest GHGs (730,767 CO2e). -4 lowest (117,954 Therefore, activities are most important success factor reducing sector. Further financial studies multi-stakeholder engagement needed these scenarios plan sustainable management.
