RT info:eu-repo/semantics/article T1 Economic feasibility study for intensive and extensive wastewater treatment considering greenhouse gases emissions A1 Molinos-Senante, M. A1 Hernández-Sancho, F. A1 Sala-Garrido, R. A1 Cirelli, G. AB Economic feasibility assessments represent a key issue for selecting which wastewater treatment processes should be implemented. The few applications that exist focus on the positive economic value ofexternalities, overlooking the existence of negative externalities. However, wastewater treatment plants(WWTPs) consume a significant amount of energy, contributing to climate change. In this context, as apioneering approach, greenhouse gas emissions (GHG) have been incorporated as a negative externalityof wastewater treatment. Within this framework, this study aims to compare the economic feasibility offive technologies, both intensive and extensive, for small communities. The results show that both theinvestment and operation costs are higher for intensive than for extensive technologies. Moreover,significant differences in the value of negative externalities were observed. This study demonstrates thatfrom an economic perspective, constructed wetland is the most suitable option for treating wastewaterin small agglomerations.
