4.3 ENVIRONMENT · FUTURE PROJECTS As part of its "Sustainable Campus" strategy, the University of Liège will soon launch several innovative projects combining ecological transition, social responsibility and regional roots. From CO₂ capture to local catering, ecosystem management, international mobility and material circularity, these structuring initiatives demonstrate a collective desire to make the campus a true laboratory of sustainability. A PILOT PROJECT TO CAPTURE CO₂ ON THE SART TILMAN CAMPUS The Department of Chemical Engineering (School of Engineering) is developing a CO₂ capture pilot project which will separate CO₂ from the flue gases produced by the biomass cogeneration unit operated at the Sart Tilman central heating site (B10). Professor Grégoire Léonard's team is receiving funding for this project from the European recovery plan via the Wallonia-Brussels Federation (NextGeneration EU, RepowerEU). From the second half of 2026, this pilot project will be able to capture up to one tonne of CO₂ per day using an amino solvent loop. The pilot project will be mobile and can be moved to treat industrial fumes as part of collaborative projects. The CO₂captured can be used by technologies developed at the FRITCO2T platform at ULiège, offering CO₂-based alternatives to fossil-based molecules. The aim is to support our society in its energy and climate transition by de-risking the most promising defossilisation technologies on a campus scale.

Created in 1997, this 240-hectare reserve is an important natural area within the Liège metropolitan area. It is managed by the Property Resources Administration (Administration des Ressources Immobilières (ARI)), in conjunction with the Wallonia Public Service. ULiège wishes to extend the reserve on the basis of new scientific knowledge, in particular following a study conducted in 2023 by Gembloux Agro-Bio Tech (Prof. G. Mahy), which identified areas of high ecological value and ecological corridors. This expansion is part of the University's longstanding sustainable forest management policy at Sart Tilman and the 'Sustainable Campuses' project, which aims to support the development of university campuses in a sustainable manner through the implementation of a development plan for Sart Tilman.
