The SUPREN SUstainable PRocess ENgineering research group is integrated in the Department of Chemical and Environmental Engineering of the Bilbao School of Engineering (University of the Basque Country). Its different R&D activities are briefly described in what follows:

  • Physicochemical characterization of fuels and urban or industrial wastes to design their valorization.
  • The development of thermochemical and valorization processes to valorize and recycle organic wastes through pyrolysis or gasification.
  • The development of hydrometallurgical processes to valorize and recycle industrial wastes.
  • The preparation, characterization and testing of heterogeneous catalysts for reforming, oxidation, hydrotreating, dehydration and hydrogenolysis processes of both fossil (oil fractions, NG) or renewable (biomass) resources.
  • The application of advanced and innovative approaches from chemical reaction engineering to develop microreaction systems or other ones with coupled selective separations (reactive distillation, membrane modules). These technologies use to be applied to hydrogen production technologies and to biorefinery processes development (biofuels and added-value intermediates or products).

All the expertise accumulated working in all the previously indicated areas allows at present the development of research projects within the following lines of R&D:

  1. Design of innovative reaction systems
  2. Development of biorefinery processes
  3. Hydrogen technologies
  4. Waste to resource (W2R)
  5. Development of hydrometallurgical processes

The R&D researchers have also experience in modeling and simulation in process engineering: experimental data processing, model tuning, process scale-up or design and optimization of real processes. Both commercial simulators and specifically developed tools use to be applied in this field.


Pedro Luis Arias and Alexander Lopez-Urionabarrenechea are in the group of 2% of the researchers most cited in scientific publications, according to the Stanford University ranking.

First publication date: 15/02/2023

There are 151 researchers from the University of the Basque Country in the group of 2% of those most cited in scientific publications: 99 in the senior list (which corresponds to the mentions the researcher receives in his professional career), 126 in the last year list (in this case the mentions for 2021) and 74 in both lists. This is recorded in the latest Stanford University Ranking of the World Scientists: World's Top 2% Scientists. According to this, the Basque public university is the second most influential in this ranking, after the University of Barcelona.

Pedro Luis Arias and Alexander Lopez-Urionabarrenechea of Supren research team appear on these lists this year. Congratulations!
