Chemical Engineering and Materials (LGPM) - EA 4038

SUSTAINABLE INDUSTRIAL PRODUCTION AS A KEY CHALLENGE FOR THE TWENTY-FIRST CENTURY

LGPM has two principal interrelated axes of interest, namely, Process Engineering and the study of Materials. Key words for the activities of this Department include: Modelling, simulation and experimentation. These activities are encountered as a common thread in all the activities of the Department (LGPM).

The complementary nature of the Department’s activities permit the application of the knowledge of microscopic phenomena to the construction of models, their simulation and the optimisation and intensification of the processes under study. Our particular know-how and competence is the application of the “sustainability” aspects (e.g. use of renewable materials, economy of materials and energy) of processes in general to bioprocesses in particular. These Departmental competences have been strengthened by the participation of the Department in the creation of a Centre of Excellence for Industrial Biotechnology (CEBB) at the end of 2010, permitting full-time employment of two Professors, two Lecturers and two Engineers. This allows us to be deeply involved in the promising field of bio-economy.


The Department is organised in three Teams:

  • Materials and Biomaterials
      Metals, wood and natural fibres
      Development and transformation processes
      Tribocorrosion
  • Chemistry and separative processes
      Liquid-liquid extraction and extraction using emulsions
      Particle transport and deposition
      Analytical and preparative chromatography
  • Bioprocesses
      Studying physicochemical and biological processes
      Multiscale bio-modelling, control-command strategies for bioreactors
      Use of microorganisms to capture CO2 and/or to treat sewage.
      Anaerobic digestion and methane generation
      Production and purification of high value molecules using plant cell cultures
