FLEXIBI : Experimental evaluation of small-scale flexi-feed biorefineries and development of a decision support tool devoted to urban and peri-urban wastes


Project summary :

Using integrated experimental and modelling approaches, FLEXIBI will study the use of agriculture, landscaping, agro-food industries and post-consumption plant biomass waste from periurban areas as feedstocks for Small scale Flexi-feed Biorefineries (SFB). FLEXIBI targets the evaluation of biomass wastes and their mixtures for biobased materials production and local energy generation via different biorefinery processes. The use of biomass from different feedstock or in mixture will allow the use local and all-year available feedstocks to limit transportation and logistics issues while promoting local production of high value molecules or energy. Three contrasted experiment zones, Nantes, Hamburg, Leuven have been selected for real case studies. Experimental data from biorefinery assays and expert knowledge collection will feed quantitative process modelling and knowledge engineering approaches to set-up decision support tools and value-creation oriented schemes for under-valorized biomass. These will be used to provide support for SFB design for specific regional/local level configurations.

Expected results include new knowledge and a decision-making support tool enabling the:

  • Evaluation of the technological, economic and environmental suitability of different types and mixtures of plant biomass to be processed by different biorefinery processes
  • Valorisation of currently underexploited waste
  • Development of innovative bio-based materials from local waste resources.
  • A decision tool for SFB implementation from feedstock to application products that will support the design of the most efficient pathways or networks to establish SFB adapted to local features

The project consortium includes 6 partners: Hamburg University, Hamburg University of Technology, Ecole Supérieure du Bois, University of Helsinki, KU Leuven and INRA as coordinator. FLEXIBI belongs to the FACCE SURPLUS ERA-NET 2nd call “small scale biorefinery” (
