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 is an agronomist (Master’s degree, 2000) and a PhD (2003) in process engineering from Montpellier SupAgro.

After a research engineer position INRA (2004-2007) in food processing, he is now associate professor at  Montpellier SupAgro since 2008. His teachings are dedicated to ecotechnology, with a focus on environmental assessment, which are mainly carried out by life cycle assessment approaches. His research activities are performed in the Laboratory of Environmental Biotechnology. He is the Elsa group leader since 2014.

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