Nowadays, one of the factors that have an impact on climate change is wastewater treatment facilities. The main greenhouse gas (GHG) emissions are carbondioxide (CO2), nitrous oxide (N2O) and methane (CH4) in waste water treatment plants. GHG emissions are caused by several items such as the electric consumption, treatment process, sludge treatment, sludge transportation for disposal in the WWTP. The purpose of this paper is the optimization and estimation of GHG emissions from a central wastewater treatment plant in an organized industrial district in Tekirdag. GHG emissions from WWTP have been calculated using ECAM web tool that is designed by WaCCliM organization. This work analyzed GHG emissions are compared and estimated for different months with in two sections. The highest emissions were estimated in December to be 226.573 kgCO2eq/month because the wastewater flow and wastewater load were increased. The highest emission in summer months was estimated to be 195.174 kgCO2eq/month for July. The results of this work showed that the most of expenses are spent through electric energy consumption and sludge transportation and disposal in the WWTP. GHG emissions are minimized if it is increased the use of renewable energy sources and is decreased to produce disposal sludges.
