The desire and need of an increasing number of our customers to source fuel from renewables matches our desire to drive bioenergy research and development forward. Fossil fuels (from oil, natural gas, coal and other minerals) increasingly appear to be a less inexhaustible source of energy.

The main types of biomass used for energy production come from production residues, residues from processing industries, dedicated crops (biofuels), and other types of biomass, for example residues from human activities.

Sofren works mainly on two types of biomass:

  • Biogas (from the first two residues mentioned above) obtained during the decomposition of organic matter in an anaerobic digestion process. It can be directly captured at landfills or produced in special biogas units. It is a combustible gas used to produce heat, electricity, or biofuel.
  • Biofuels are derived from biomass. They form two industrial groups: ethanol and biodiesel. They can be used pure or as additives in conventional fuels. Beet, cereals, oilseeds (rapeseed, sunflower, etc.) make it possible to produce these biofuels.


The added value provided by design offices combined with the experience of its engineers in process engineering enables Sofren to be involved at every stage of a biomass project: upstream from the concept by investing in research and development, particularly through specialized theses on the development of biomass, to the execution of design projects and biomass plant construction.

The research & development project currently being conducted in partnership with the UTC (University of Technology of Compiègne) enables Sofren to position itself on innovative biomass development areas using wood bark by means of developing an innovative and groundbreaking process.
