Vacancy details

General information


The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.

Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.

The CEA is established in ten centers spread throughout France



Description de l'unité

CEA-Liten is member of «Institut Carnot Énergies du Futur ». Based on CEA Grenoble and INES (Chambéry) centers, he is dedicated to the energy transition. Its activities focus on several key areas: solar energy, smart grid management, batteries storage and hydrogen with the view to improving energy efficiency and circular economy approach. CEA-Liten covers a wide range of applications in energy production and distribution, transportation, industrial processes, and environment markets.

Job title

Post-doc : Environmental & circular economy H/F


Environmental evaluation of circular economy loops considering resources dissipation

Contract duration (months)

12 + 6

Job description


In the last years the concept of circular economy has risen. Circular economy aims to break with the precept of resources abundance and with the linear scheme “Extract, produce, use, throw out”. The French ecological transition agency (ADEME) defines circular economy as “an economical system of exchanges and production, which - at each stage of products, goods and services life cycle - aims at enhancing resource use efficiency and at reducing the environmental impacts while developing human well-being”[1]. In June 2020, the Life Cycle Initiative identifies Life cycle assessment (LCA) methodology to assess the environmental impacts of circular economy strategies[2]. Recycling, by transforming wastes into raw materials, is one of the circular economy strategies. The environmental evaluation of recycling loops still suffers today of methodological pitfalls. One of this pitfall is the lack of resource circularity quantification at these loops level and, in particular, the lack of resource dissipative flows quantification.

Objectives of the post-doctoral mission:

In order to address this problematic, more specifically for the mineral resources, the Measure, security and environment laboratory of the CEA-LITEN (based in Grenoble, France) and the Raw materials and wastes unit of the BRGM (based in Orléans, France) offer a 18-monts post-doctoral position to develop indicators for the environmental evaluation of recycling loops and technologies considering resources dissipation. With the goal to use these indicators in LCA. To reach this objective, several work steps will be taken:

A state-of-the-art review:

  • On the material loops environmental evaluation methodologies, especially on the recycling loops;
  •  On the consideration of dissipative flows in LCA;
  • On circularity indicators that can be developed based on LCA results

A methodology proposal to develop indicators that assess the environmental impacts of circularity considering resources dissipation. This proposal will rely on:

  • A summary of the work on the topic at the LITEN and at the BRGM;
  • The identification and quantification of dissipative flow at the level of unit processes associated to recycling and considering the function of the resource.

The proposed methodology will be tested on a case study: a recycling technology put in place at the LITEN;

A summary of the obtained results:

  • Parameters to consider in the quantification of resource dissipation at the recycling loops level;
  • Choice of the indicators to consider to evaluate the circularity environmental performances;
  • Environmental impacts comparison for a set of recycling technologies, in particular regarding their resources use;
  • Regarding each recycling technology, identification of the conditions needed for a good environmental performance regarding materials economy;
  • Guidelines for the environmental evaluation of circular economy loops for the technical team at the LITEN and at BRGM.



Applicant Profile

The candidate owns a Ph.D in environmental sciences or engineering since less 2 years.
She/he will work in close collaboration with each team at the CEA-LITEN and at BRGM. She/he will have the following skills:
- Environmental evaluation methodologies application (LCA)
- LCA software application: GaBi, Simapro, Brightway,…
- Office software application
- Process engineering knowledge
- Fluency in English and willingness to learn French (for non-speaker candidate)
- Adaptation capacity and team work
- Autonomy and sense of initiative
- Inclined to mobility (the duration of the contract is shared between Grenoble and Orléans)
- Ability to summarize
- Adjust her/his discourse to the audience
- Scientific writing

This job offer represents for you a first professional experience since your doctorate
