Smart cities are considered imperative for a sustainable future and emerged as a solution to address the sustainability challenges. This transition is considered as essential by policymakers and is reflected in the establishment of the UN Sustainable Development Goal.

There are no smart and sustainable cities without a resource efficient and circular use of materials and products. Measuring the social and environmental impacts of products and its circularity is very important to support all changes required towards smart cities, as the energy transition.

Through the link of the existing software (HSC Chemistry, Granta Selector and openLCA), TripleLink will allow improvements to product-oriented assessment and the circularity of products. It will also provide the possibility to calculate resource indicators describing criticality from a resource-economic perspective and from a conflict perspective, with simple application and clear interpretation.

The Université de Bordeaux, who is the coordinator of TripleLink, is ranked among the top French universities for the quality of its education and research. A multidisciplinary, research-focused, international institution, which leads an ambitious development program with its partners to further promote Bordeaux as a “Campus of Excellence”.

Based at the University of Bordeaux in the Institute of Molecular Sciences (ISM) is the CyVi Group, an interdisciplinary group of scientists working on research methods of and applications to sustainable chemistry and life cycle assessment. ISM is a Joint Research Unit between CNRS, Université de Bordeaux and Bordeaux INP.



TripleLink will provide the processing value chains in the raw materials sector with an integrated assessment tool, more precisely the project will:

Develop an optimized software solution integrating three commercial software packages: Granta Selector (Ansys Granta), HSC Chemistry (Metso Outotec) and openLCA (GreenDelta);

Integrate guidance for the recyclability of materials in the software;

Enhance the industrial capacity in the raw materials value chain to use LCA and thermo-economic information (innovation, footprints and handprints);

Advance the development of criticality and circularity indicators methodologies and its integration in the software;

Prepare education material using the results of the methods and technology development.
