In Indonesia, the waste sector is responsible for 10.59% (130,188.21 GgCO2e) of global warming emissions, one of which is from campus domestic wastewater due to the lack of wastewater treatment plants. Only 0.2% of the 6,472 campuses have treatment systems. For example, Universitas Negeri Malang (UM) uses a fabricated anaerobic baffled reactor (FABR) for wastewater treatment plants as part of its green campus initiatives; however, it is available only for several buildings and does not treat all wastewater generated from campus activity. However, the Life Cycle Assessment (LCA) of ABR systems has not been widely studied, especially when used to treat campus wastewater. This study aimed to conduct the LCA of the laboratory-scale ABR system in campus wastewater treatment with a gate-to-gate scope using Simapro 9.1.11 and the CML-IA Baseline. Three scenarios were tested: untreated wastewater, ABR equipped with peristaltic pumps, and ABR without pumps. The results indicated that ABR treatment had a significantly lower environmental impact than untreated wastewater, with the greatest reduction in global warming potential (1.51E-08 to 4.98E-11), followed by reductions in eutrophication and photochemical oxidation. This study was limited to the ABR system; future research could be expanded to include the full lifecycle, from material collection to the final results. © by Authors.
