Traditional processes can’t handle complex streams, leaving valuable PET unrecycled.
From complex PET waste to uncompromised quality material.
Thanks to our unique enzymatic recycling process,
we transform complex PET/polyester waste, into virgin-like,
sustainable and circular material
Market Challenges
Beyond the limits of
Beyond the limits of
traditional recycling,
circularity begins.
Conventional recycling degrades PET performance after a few cycles.
PPWR, EPR, SUPD and rising quotas require innovative technologies.
Process explanation
Breaking boundaries with enzymatic recycling.
As pioneers in biological solutions, Carbios has developed an enzymatic recycling technology that goes beyond the limits of traditional recycling. Our process can depolymerize even the most challenging PET waste mixed, colored, or contaminated back into its original monomers.
Waste preparation
01PET waste (bottles, trays, textiles, etc.) is shredded, melted, and then transformed into expanded granules to maximize the surface area in contact with the enzyme.
Enzymatic depolymerization
02The expanded flakes are placed in a reactor with water and our patented enzyme, which depolymerizes PET — even colored, complex or soiled — in less than 24 hours.
Filtration
03The resulting solution is filtered to remove solid residues and then passed through a bed of activated carbon to retain micropollutants (dyes, etc.).
Monomers purification and separation
04
The two monomers are isolated,
with a purity greater than 99.5% :
-Terephthalic acid (r-PTA) (solid)
-Monoethylene glycol (r-MEG) (liquid)
Benefits
Produce virgin-quality material for packaging, textiles, and more, unlocking true circularity for the industry.
