Principle of CARBIOS enzymatic biorecycling process:

Unlike currently used plastics recycling processes, which are primarily thermo-mechanical, the recycling process developed by CARBIOS is based on highly specific biological tools: Enzymes!

This new approach enables the specific de-polymerization of a single polymer (e.g., PET) contained in the various plastics to be recycled.  At the end of this stage, the monomer or monomers resulting from the de-polymerization process will be purified, with the objective to re-polymerize them, thus enabling a recycling process to infinity.  Eventually, the plastic residues not degraded during the first stage will be de-polymerized in the same way in a second stage by applying a different enzyme that will de-polymerize other polymers in the same way as in the first stage.

For the first time in the history of the plastics industry, it is possible to recycle plastic waste to infinity to create new plastic materials and to accomplish this without a sophisticated sorting process.

CARBIOS’ recycling bioprocesses for plastics provide the means to:

  1. Recycle plastics to infinity by returning to the original monomers which can be used in all applications in which the original material was used;
  2. Recover in the recycled materials the same level of performance displayed by the original materials.

Among plastic waste, CARBIOS is particularly interested in polyesters (PET, PLA, etc.) and polyamides.  These polymers have chains of monomers that are easily identifiable by the enzymes, and are thus easier to de-polymerize.

Therefore, this technology particularly targets the global market of plastic bottles (water, milk, sodas, cosmetics…), packaging and films.  

CARBIOS converts plastic waste global market into a new source of value creation for industrials.
