Optimize material and energy flows in the design and manufacturing of goods and services


Circular Economy aims at minimizing the impacts of human activities on the Environment, for example by pooling material, water and energy flows with a life cycle perspective and in an integrated metabolism approach. Circular Economy is deployed thanks to strategies like industrial ecology, eco-design of products and services, product-service systems, functional economy…

The four LGI teams are all particularly implicated on Industrial Ecology issues. Current research themes deal with:

  • Eco-design and eco-innovation methods and tools, including Life Cycle Assessment (LCA) of products and services, technologies families, value chains...
  • Industrial symbioses and technico-economic analysis of eco-industrial parks
  • Circularity indicators and analysis of prospective scenarios
  • Sustainable supply chain (reverse logistics, ecosystem services and sustainable supply chains…)
  • Energy efficiency and optimization of materials flows
  • Technico-economic studies of industrial value chains including externalities
  • Decision making in complex environmental under  uncertainties

These research projects are applied in numerous industrial sectors, however sustainable buildings, cities and mobility are particularly targeted.

5-years ambition

Innovative technology potential characterization: The topic focus on how to embed innovative and sustainable technology into complex system. This topic aims at tackling issues related to modeling, simulating and optimizing multi-scale, multi-physics and multi-criteria to generate sustainable complex systems architectures.

Development of circularity indicators: The issue is to define circularity indicators for products, services and value chains in order to highlights their circularity performance and moreover to drive industrial activities towards much more sustainability.

Performance assessment of projects in circular economy: The main issue is to enrich the assessment process of such project integrating environmental impacts and social impacts. The objective is to propose new method to assess the impact investing (including, environmental, social, economic and governing aspects).
