ESTIMATE OF METHANE GAS EMISSIONS FROM STUDENT’S DOMESTIC WASTEWATER AT THU DAU MOT UNIVERSITY

Abstract

Based on the method of collecting calculation data according to the IPCC 2006 guidance on the National Greenhouse Gas Inventory, the study calculated methane emissions from domestic wastewater of students at Thu Dau Mot University in 2 cases is based on the number of students and the case is based on the actual amount of water used by the school. The research team collected data related to the calculation including the number of students, the wastewater treatment system, especially the amount of water used by the school (in the first 9 months of 2020), Next, the group analyzed and calculated the methane emissions. The final calculation results show that the amount of CH4 gas (185,769.29 tons/year) calculated in the case based on the number of students is 14.86 times higher than CH4 gas (12.25 tons/year) generated in the case based on the actual amount of water facilities used by the school. From the results obtained, the topic will serve as the basis for the school to evaluate the potential of methane gas recovery to create an energy source of economic value, help protect the environment and raise students' awareness.
