Circular Economy


The Circular Economy, in addition to a global concept on which the main efforts of society are based, is one of the areas in which CARTIF has been working very hard for many years.

The efforts of this area are focused on eradicate the typical linear point of view on processes (and therefore on the economy), favoring a circular approach based on promoting the zero waste concept, through the sustainable management of residual streams and by-products, as well as the Research in new product alternatives.

These activities include, among others, the valorization of waste, favoring techniques of minimization, reuse and advanced treatments of effluents or the minimization of polluting air emissions.



  • Testing of chemical and thermal recycling processes of plastics.
  • Optimization of anaerobic digestion processes in pilot plant: biogas.
  • Viability of biogas upgrading plants: biomethane.
  • Microalgae for treatment of effluents and recovery of by-products.
  • Characterization of solid waste for the control of drying processes.
  • Deployment of good sustainable practices in hospitals: energy,water and waste.

Activity fields

  • Recovery of organic waste/high load residual effluents.
  • Nutrients recycling: closing cycle.
  • Recovery of plastic waste.
  • Recovery and valorization of mining waste.
  • Thermo-chemical treatments: pyrolysis, torrefaction, gasification, hydrothermal carbonization.
  • Generation and use of biogas, biomethane and syngas.
  • Integral management of municipal waste.


  • EP14380020: Surface treatment of asphalt road pavements with a photocatalitic composition for the abatement at atmospheric pollutants.
