Integrated Transformation of Renewable Matter (TIMR)

ESCOM research team with TIMR associates the skills and know-how of UTC in process engineering and those of the Compiègne based École Supérieure de Chimie Organique et Minérale (ESCOM) in the fields of chemistry and chemical engineering.


The objectives of TIMR are: to develop, validate and implement the knowledge and know-how intended for the processes and reactions of transformation of renewable material.

The unit’s research activities are part of scientific and technological issues, and current societal issues related to the optimization of the use of resources and the renewal of industrial processes in connection with a sustainable development approach.

Research teams and thematics

TIMR’s research activities revolve around 5 teams with complementary skills and the Chemistry and Green Processes Chair of Excellence:

Characterization, monitoring of microbial activities in complex natural and industrial environments, and control of bioprocesses via a multidisciplinary approach.

Participation in the design and development of industrial processes with the constraints of minimizing environmental impacts and controlling industrial risks.

Mastery of the behavior of complex dispersed systems in the processing and shaping processes, interface phenomena, behavioral properties of divided solids.

Alternative techniques for synthesizing new molecules from biomass, clean and economical synthesis processes, valorisation of biomolecules and biobased materials.

Mastery of biomolecule extraction and separation processes, implementation of unconventional physical transformations, emerging transfer intensification processes.

The objective of the chair is to amplify the integration between chemistry and process engineering through a multidisciplinary approach favoring the development of innovative processes.

Dr. Estelle LEONARD

One Health is an emerging concept that aims to bring together human, animal, and environmental health. Coming from the “One Medicine” concept that plead for a combination of human and veterinary medicine in response to zoonoses, the “One Health” concept therefore constitutes a global strategy. It highlights the need for an approach that is holistic and transdisciplinary, and incorporates multisector expertise in dealing with the human health, animals, and ecosystems. In this context, fighting against human bacterial strains without impacting the environment is crucial, and the use of photochromes can help achieve this goal. Photochromic molecules are molecular switch upon illumination that can, in the example of azobenzenes, pass from trans to cis form, changing of conformation, but also polarity, dipolar moment, color, or even physicochemical properties. That is how an azobenzenic surfactant or complex can be active against bacteria in the dark, and loose its antibacterial effect upon UVAs. Coupled to antibiotics, the contrary is also possible depending on the bacterial target reached by the molecule. Our aim is thus to explore all the possibilities of such molecular switches in the “One Health” domain.
