Almost every waste management step generates greenhouse gas (GHG) emissions; hence, it is imperative to design appropriate treatment methods from sources to disposal sites for reducing their environmental impact. In this study, to provide guidelines for developing a suitable waste management strategy for Depok, Indonesia, emissions from four waste management scenarios for the city are calculated. These scenarios involve treatments such as the application of Waste Treatment Unit (WTU), incinerator, anaerobic digester, composting, and landfill.
