A majority of the solid waste produced in Surabaya is handled by the Surabaya Environmental Agency (Dinas Lingkungan Hidup, DLH). This process includes sorting, and colleting waste from local sources, transporting waste to and treating waste in local facilities, as well as final processing of waste done in landfills. Each of these processes will produce its own amount and type of GHG emissions. This study focuses on the emission coming from local facilities used to treat waste, namely TPS3R and Rumah Kompos. These facilities receive waste from local communities and produce compost and recyclable materials, creating GHG emissions in the process. This research estimates how much GHGs are emitted from these facilities from its compost production and energy consumption using available tools, and then compare its emission to the amount of waste that it processes. This comparison will show how much GHG each facility emits for every ton of solid waste handled (Facility Emission Factor, EF) which equates to its waste handling performance. Results show that the lowest EF achievable by TPS3R and Rumah Kompos facilities in Surabaya is 0.210- and 1.988-ton CO2eq/ton waste, respectively. This performance level is used as a baseline for increasing the amount of waste treated in these facilities with no additional emission load. When this estimation is applied, the total waste treated in Surabaya could increase by 11%, treating an additional 691 tons of waste per year and reducing waste going to landfills, which in turn reduces overall emissions of the waste sector.
