Arising metropolitans, industrialization and urbanization caused urgency to solve the sludge problem appropriately in the world, especially in developing countries such as China; sewage sludge treatment technology and site selection is crucial for cost reduction; the objective of the research is to investigate the economic sustainability of Shanghai Bailonggang sewage sludge Treatment Plant and the newly constructed sewage sludge treatment plant in Changsha. The economic sustainability of a wastewater treatment plant in Helsinki, Finland is discussed as well in this paper as a contrast subject. The results have showed that increased economic burden and growth of plants globally increased amount of sludge that affected sludge treatment location scarcity to energy intensive transportation methods issuinganaerobic digestion to be vital in wastewater treatment plant to utilize energy recovery. Viikinm?ki has 25 341MWh energy recovery which has officially reported to covers 60% of plant?s needsand heat recovery by engines with AD are altogether 8 922MWh (100%) which is total wastewater treatment plants heat using capacity.
