OptiReUse, a decision support tool for wastewater reuse in agriculture irrigation based on Life Cycle Assessment results

This decision support tool was designed to evaluate the environment efficiency of wastewater reuse for agriculture irrigation among other options. The aim of this decision support tool is to guide the interpretation of LCA results by reducing, gradually, the non-discriminant impacts in order to resolve the difficulty of deciding with a large number of criteria. This framework has been applied to a representative reclaimed water reuse application case conducted in the experimental platform of Murviel-Les-Montpellier (Hérault, France) which was then generalized by making modeling assumptions to address different reuse scenarios.
