4Refinery: Low-emissions biofuels from biomass

4REFINERY is a project by the European Union that aims to develop and demonstrate the technical, environmental, and socio-economic viability of biomass transformation into next-generation biofuels with low CO2 emissions.

In this project, which is within the framework of the EU's scientific innovation project, Horizon 2020, we are participating alongside seven European companies and technological centers including SINTEF, CNRS, BTG, VTT, Aalborg University, E4Tech, and MOL.

In order to carry out this project, two waste-recovery processes are being analyzed: pyrolysis and hydrothermal liquefaction, and the integration of its products into different conventional refining processes.

The project will include an analysis of the life cycle of the products obtained, technical and economic evaluations of the alternatives, and finally, testing in pilot plants that will allow us to evaluate the technical risks of the studied scenarios.

The main objectives of this project are:

  • To develop new advanced biofuel production routes using biomass conversion technologies: hydrothermal liquefaction and rapid pyrolysis.
  • To study scenarios for the obtained products' integration as recovered biomass into the refineries' existing processes.
  • To develop technological solutions to meet society's major social and environmental challenges.
  • This project has received funding from the European Union's Horizon 2020 research and innovation program through the grant agreement no. 727531.
