“…The biogas generated from wastewater treatment can be used as a natural gas substitute or converted into heat and electricity. Anaerobic treatment for waste-to-biogas conversion systems is the most popular technology for energy recovery from wastewater [8]. The combined anaerobic and aerobic system followed by biogas recovery for the source of energy also can reduce GHG emissions up to 61.72% [9].…”

Wastewater treatment contributes direct greenhouse gas (GHG) emissions in the atmosphere. The study aims to estimate the amount of methane (CH4) and carbon dioxide (CO2) emitted from domestic wastewater treatment plants (WWTP) in Bandung Regency throughout the years 2019-2022. Wastewater treatment processes in the WWTP consist of anaerobic, facultative, and maturation ponds. Data series of water quality from each process were collected on a monthly basis from years 2019 to 2022 to estimate direct emissions. Emission factors used in this study were derived from IPCC Guidelines and using the Tier 1 method. The highest GHG emission from WWTP Bojongsoang was about 513.44 tonCO2e in December 2021. The monthly average CO2e emissions from year to year increased about 40.12%. The average GHG emission from WWTP Bojongsoang from the year 2019 to 2022 respectively was about 81.33 tonCO2e/month, 135.21 tonCO2e/month, 229.26 tonCO2e/month, and 193.89 tonCO2e/month. Overall, the percentage of CO2e emission from anaerobic pond was about 93.57%, from facultative pond was about 4.86%, and from maturation pond was about 1.57%. The highest CO2e emissions occurred in the anaerobic pond along with the highest COD reduction also took place in the anaerobic pond.

Greenhouse gases are mainly comprised of carbon dioxide. In 2021, anthropogenic CO2 emissions in the atmosphere have risen to 37.9 Gt, a 60 % increase from the levels observed in 1990. The production of high-value products using CO2 can contribute to decreasing atmospheric CO2 levels and advancing the objectives of the Green Deal. In Latvia, biofuel–biomethane production may also present a viable solution. Diversifying the energy sector, which can benefit the country's economy, is another advantage of this scenario. The study examines the transformation of a Latvian biogas production facility, which shifts towards producing biomethane as its final product. The study also involves the computation of greenhouse gas emission reductions resulting from utilizing biomethane instead of biogas in the network.
