Actual position and research subject
Professor at INSA Toulouse, TBI.
Current professional interest and research activity in chemical engineering especially in relation with environmental goals, eco-design of bio-chemical processes, impact and risk assessment and pollutant emission modelling.
Sustainable bio-chemical technologies through environmental assessment and eco-design approaches
Development of integrated modelling platforms for predictive and parameterized Life Cycle Assessment (LCA) dedicated to eco-design of bio-chemical processes. Platforms couple specialized and homemade IT tools for Process Modelling & Simulation and LCA. Application for CO2 capture and utilization processes, bio-based products and technologies, water treatment.
Methodological developments, new models and IT tools in Sustainability science
- Building a new Life Cycle Assessment method (dynamic LCA) by including time dimension in value chains’ representation and dynamic functioning of processes. Developed CCI-tool for Climate change impact – time dependent indicators, online calculator https://www.insa-toulouse.fr/cci-tool/ .
- Thermodynamics-based assessment methods (Emergy, Exergy) – development and application in the field of industrial processes.
- Modeling tools for bioeconomy and circular economy.
Environmental impact and risk assessment of materials
Application of thermodynamic, (geo)chemical and mass transfer modelling to assess the environmental behaviour of materials under various environmental conditions – modelling of pollutants emission from materials, wastes and soils, and of the impact of pollutant release on water sources.
