At the laboratory of thermochemical processes, the focus of our research is on the valorization of wastes by thermochemical treatment. We perform both fundamental and applied research. Our research can be divided in two main parts.

The first part deals with the processing of waste biomass with an aim to obtain products with a higher added value. We perform pyrolysis for the production of biochar, carbonization to produce activated carbon sorbents and torrefaction to obtain coal-like high-energy-density materials.

The second part of our research deals with the chemical recycling of waste plastics. Chemical recycling offers the possibility of transforming waste polymeric materials back to their original monomers or other valuable chemicals which can be used as feedstocks in chemical and petrochemical industries. At our laboratory, we carry out thermal and thermo-catalytic pyrolysis for the chemical recycling of waste plastics.

Last but not least, we deal with hydrogen production using the catalytic (dry and steam) reforming of waste gases emerging from thermochemical treatment of both biomass and waste plastics.
