Partenariat 2011 Irstea/Onema – Theme : Ecotechnologies and pollutions.
Action 24 « Analyse environnementale de cycle de vie du système assainissement »
This work builds upon the previous LCA studies delivered in 2010 and scopes a comparative LCA (Life Cycle Assessment) study of two wastewater treatment technologies designed for domestic sewage. This comparative LCA study is carried out between (i) a vertical flow constructed wetland and (ii) an activated sludge.

Partnership 2010 Irstea/Onema – Theme : Ecotechnologies and pollutions.
Action 28-1 « Analyse environnementale de cycle de vie du système assainissement »
The following documents scope the LCA (Life Cycle Assessment) of two wastewater treatment plants using (i) a constructed wetland technology or (ii) a conventional activated sludge, both designed for treating domestic sewage. Inventory data relative to construction and operation of these wastewater treatment plants are described in these documents. This action required a close collaboration between Irstea specialists in environmental assessment (Irstea UMR ITAP, Montpellier) and experts in sanitation (Irstea UR MALY, Lyon et HBAN, Antony).

Eva Risch graduated from the Bordeaux Higher National School of Physics and Chemistry in September 2009 with an engineering background in physics and chemistry and a research masters in environmental chemistry. In May 2010, Eva joined the ELSA Team as a Irstea research engineer. Her role is to help develop Life Cycle Assessment methodologies by carrying research on certain environmental processes. She has focused on wastewater treatment efficiencies, comparing a conventional activated sludge wastewater treatment plant with a vertical flow constructed wetland as part of a Irstea – ONEMA (French National Agency for Water and Aquatic Environments) collaboration. Her interests include elemental mass balances in the studied processes, which allow one to quantify their utility functions as per the treatment of waste waters.
Topics: Life cycle assessment, wastewater treatment plant, vertical flow constructed wetlands, activated sludge, elemental mass balance.
