Brief description of research aims
Deusto Sustainable Research Group is a research team created at Deustotech, a private non-profit institution at the University of Deusto’s Faculty of Engineering for applied research in new technologies. Since 2005, DeustoTech's mission has been to support ICT activities in companies and society through research, technology development, innovation and knowledge transfer.
We focus our activity around TRLs 2-7 and articulate it in four applied fields: Industry, Mobility, Energy and Society, with a fifth, the Chair of Applied Mathematics, as a transversal activity and support for the previous four. We work with heterogeneous data throughout the lifecycle and in compliance with the ethical and humanist principles that characterise the University of Deusto.
The team has an established team leading research in the environmental sector, including sustainability, resource efficiency and circular economy.
Research areas
- The circular economy and the sustainable use of resources
