Comments on the approach "Sustainability assessment using indicators":
1/ Goal and scope definition: definition of the system boundaries (according to the scale of the wastewater treatment systems) and sustainability indicators (functional indicators - like minimal required effluent quality…- , economic indicators, environmental indicators, social-cultural indicators - like acceptance, institutional requirements…- ).
2/ Inventory analysis: the sustainability indicators are quantified or indicated qualitatively. In this part, tools like mass/energy balance, cost-benefit analysis, risk analysis and factor analysis can be used.
3/ Optimisation: All the tools are combined in an integrated assessment and this makes the selection of the sustainable wastewater treatment systems a multi-objective optimisation problem.
