Angel Avadi

Angel Avadí is a researcher at CIRAD, research unit Recycling and risk. He deals with the environmental assessment of solutions for the recycling of organic residues, especially regarding strategies for returning nutrients to agricultural soils. Previously, in 2014, he completed a PhD from Université Montpellier 2 and IRD focused on the sustainability assessment of supply chains based on the wild caught Peruvian anchovy. These supply chains include fisheries, reduction into fishmeal and fish oil, aquaculture and fish processing for direct human consumption. In 2014-2015, he engaged in postdoc research at INRA Rennes on the challenges of applying life cycle assessment to describe whole agricultural regions. His academic training at the undergraduate and master levels spans IT (with focus on e-learning), business and sustainability science (material flow management and other aspects of industrial ecology).

Mary Hanhoun (2011 – 2012)

Mary Hanhoun is a civil engineer (2003) and a PhD in process and environmental engineering from INP of Toulouse (2011).

In October 2011, Mary joined the ELSA as a post-doc to work on the Phosph’OR project. This project aims to develop recycling processes for phosphorus with agricultural purposes. Mary’s mission is to assess the environmental impact of these processes by the Life Cycle Assessment (LCA), assess the impacts of each process with a view to application in agriculture and to build a sustainable and well-thought process.

Topics: Life cycle assessment, wastewater treatment processes, phosphorus recycling

Pierre Collet (2009 – 2012)

Pierre Collet is graduated from the Montpellier National School of Agronomy, and specialised in water, cultivated lands and environment management. He follows a PhD thesis since february 2009 in in the Laboratory of Environmental Biotechnology on the environmental assessment of production of biogas from microalgae, within the ANR project “Symbiose”. One of the main objective of this PhD is the integration of temporal dynamics in LCA.

Topics: Life cycle assessment, microalgae, anaerobic digestion, dynamical modelling

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.
