Antoine Esnouf (2015 – 2022)

Antoine Esnouf is an agronomist from Montpellier SupAgro (2014), specialized in green chemistry and bio-process for a sustainable development. After an internship at Irstea in Life Cycle Assessment (LCA) applied to a territorial biogas plant, he joined the Elsa research group in January 2015 as a PhD Student of the Laboratory of Environmental Biotechnology (INRA LBE). Being part of the Green AlgOhol project, his work deals with the environmental analysis of a production system of agro-fuel from seaweed. One of the main objective of this thesis is the development of a methodology for analyzing the correlations between the variability of Life Cycle Inventory results and LCA results.

Juliette Langlois (2010-2013)

Juliette Langlois is an agronomist graduated from Montpellier SupAgro (2009). She is currently pursuing a PhD on the Life Cycle Assessment (LCA) of production system of bioenergy from saeweed cultivated in open ocean (WinSeaFuel project). Her research deals with the modelisation of the land use impact on the ecosystems.

Topics : Life Cycle Assessment, macroalgae, anaerobic digestion, marine biodiversity.

Arnaud Hélias

Arnaud Hélias has a background in biological systems modelling and devotes his research activity to the environmental impacts of human activities, within the reference framework of Life Cycle Assessment. He is interested in the modelling of causal relationships, from the determination of pollutant emissions and resource consumption to the quantification of damage caused to ecosystems. The objective is to find a compromise between representativeness and operationality.

Arnaud Hélias, PhD (2003) and habilitation (2016) in process engineering is an INRAE senior scientist. He is the author of about sixty articles and has been in charge of environmental assessment in several collaborative projects (ANR Symbiose, Phosph’OR, WinSeaFuel, GreenAlogOhol, Cost-to-Coast, FUI Salinalgue, Algraal, Ademe Surfact’Alg…). He also holds the Elsa-Pact industrial chair in LCA, is chairman of the scientific and technical council of the GIS Revalim (a scientific group composed by Ademe – INRAE – agricultural and agri-food technical centres, on French agricultural data for LCA), and is an expert for the government on the environmental labelling of food and textile products, expert for the scientific council of IFPEN (French Institute for Petroleum and New Energies), active member of the GLAM initiative (creation of a global life cycle impact assessment method, under the aegis of the United Nations Environment Programme), head of the joint research unit ITAP: Technologies and methods for tomorrow’s agriculture and from 2014 to 2018, leader of the Elsa group.

Topics: Ecodesign, Training, Life cycle assessment, microalgae, seaweed, anaerobic digestion, dynamical modelling, inventory.
