Biotechnology applied to obtain printable polymers with biomedical applications using agrofood by-products from Navarra

  • 2021-2023


  • To find new innovative solutions for the valorization of agro-food wastes from the Navarran industry through the application of white biotechnology.
  • To develop, produce and validate new biodegradable, biocompatible and printable materials based on polyhydroxyalkanoates, for their application in biomedicine and tissue engineering, using different 3D printing techniques.
  • The development of these biomaterials is carried out through the combination of biotechnological processes of bacterial fermentation and genetic engineering.


  • Characterization and fractionation of agro-food wastes.
  • Scaling up the fermentation and downstream processes (recovery and purification) for the production of PHAs (P3HB and P3HB-co-4HB) with microbial strains identified for this purpose.
  • In a final phase of the project, the new biotechnological tools developed at AIN will be scaled up in the CENER pilot plant to carry out efficient production of poly (3-hydroxybutyrate-co-4-hydroxybutyrate) (P3HB-co-4HB) copolymers.
  • Techno-economic and environmental feasibility assessment of the processes developed.
