Developing new methodologies to try to solve a critical environmental problem, the destruction of plastic wastes proceeding from petroleum


REPLACE aims at developing new methodologies to try to solve a critical environmental problem, the destruction of plastic wastes proceeding from petroleum.

REPLACE investigates environmentally friendly thermochemical procedures less energetically demanding than common treatments. However, REPLACE’s greatest breakthrough is the revalorization of the compounds obtained from the destruction of the plastics through biotechnological procedures. By this way, highly valuable bioproducts suitable to synthesize other environmentally friendly materials will be produced.

Optimizing the combination of both technologies implies the Project’s main challenge.



  • Use plastic wastes as raw material to obtain bioproducts
  • Reduce the energetic requirements of thermochemical treatments
  • Reduce the treatment times and increase the efficiencies of biotechnological treatments
  • Make the most of the degradation products from plastics as carbon source for the biotechnological treatments
  • Know the process’ economic, environmental and social costs


  • Study different process conditions to optimize both thermoche-mical and biotechnological techniques by using model compounds
  • Analytical determination through several techniques: GC-MS, HPLC-UV, SEM, FTIR, DSC
  • Experimenting with real samples of plastic wastes
  • Coordinated actions of 4 working groups, each one of them integrated by several investigators

Expected results

  • Complete degradation of plastic residues under energetically viable conditions
  • Complete consumption of the compounds proceeding from the plastic degradation by microorganisms
  • Optimization of the amounts of bioproducts obtained from the biotechnological treatments
  • Development of a process with a negative carbon footprint

BioSFerA aims to develop a cost-effective interdisciplinary technology to produce sustainable aviation and maritime fuels. The overall process, combining thermochemical, biological and thermocatalytic parts is based on the gasification of biomass and other biogenic waste and the 2-stage fermentation of the produced syngas.
