CARBIOS achieves a major milestone in the optimization of its biorecycling process of PET based plastics

  • Time of hydrolysis divided by 3: 97% conversion in 24 hours

  • A level of performance reinforcing the competitiveness of this proprietary process

  • Towards an acceleration of the industrialization stage

Clermont-Ferrand, France, April 12, 2018 (6:45 AM CEST) – CARBIOS (Euronext Growth Paris: ALCRB), pioneer company in the field of bioplasturgy, announces a major milestone in the optimization of its biorecycling process of post-consumer PET plastic bottles, making it possible to strengthen its economic competitiveness and accelerate its scaling up towards the industrial demonstration stage.

Previously, CARBIOS announced that it had discovered a particularly well-suited enzyme to degrade PET plastics into their original monomers: PTA (terephthalic acid) and MEG (mono ethylene glycol).

Following these results,  work has been undertaken to optimize the enzyme used in CARBIOS’ biorecycling process, with the support of the teams from Toulouse White Biotechnology (TWB), and in particular the Engineering Laboratory of Biological Systems and Processes (LISBP). A molecular modelling study has been carried out to analyze the relations between the 3D structure of the enzyme and its efficiency. This has made it possible to set targets enabling to improve performance and achieve a conversion rate that only CARBIOS can claim today. Thus, the time of hydrolysis has been divided by three, 97% conversion being obtained after 24 hours of reaction. Such a result enables to optimize the profitability of the process and significantly increase the flows of PET waste that can be treated enzymatically.

Alain MARTY, Scientific Director of CARBIOS commented: “Today, we are the first in the world to achieve such a high level of performance in the biological recycling of PET plastics. Our work represents a major move forward that will enable the entire plastics industry to engage in a responsible transition towards circular economy.

Jean-Claude LUMARET, CEO of CARBIOS adds: “This is undoubtedly a key step that reinforces the economic potential of our biorecycling process which is applicable to all PET plastics, whether they are coloured, opaque or complex. We are already working with TechnipFMC and other leading industrial and academic partners to lead this year’s pilot stage of our technology. Given our progress, we decided to accelerate these developments and initiate the industrial demonstration stage in 2019 with the set-up of a 10,000 metric tons plant that will produce the first volumes of virgin PET from our technology by mid-2021.

About Carbios

Carbios, a green chemistry company, develops biological and innovative processes to revolutionize the end of life of plastics and textiles. Through its unique approach of combining enzymes and plastics, Carbios aims to address new consumer expectations and the challenges of a broader energy transition by taking up a major challenge of our time: plastic and textile pollution.

Established in 2011 by Truffle Capital, the mission of Carbios is to provide an industrial solution to the recycling of PET plastics and textiles (the dominant polymer in bottles, trays, textiles made of polyester). The enzymatic recycling technology developed by Carbios deconstructs any type of PET plastic waste into its basic components which can then be reused to produce new PET plastics of a quality equivalent to virgin ones. This PET innovation, the first of its kind in the world, was recently recognized in a scientific paper published in the prestigious journal Nature. Additionally, Carbios is working hand in hand with multinational brands — like L’Oréal, Nestlé Waters, PepsiCo and Suntory Beverage & Food Europe — to implement its technology, and to lead the transition toward a truly circular economy.

The Company has also developed an enzymatic biodegradation technology for PLA (a bio sourced polymer) based single use plastics. This technology can create a new generation of plastics that are 100% compostable in domestic conditions, integrating enzymes at the heart of the plastic product. This disruptive innovation has been licensed to Carbiolice, a joint venture created in 2016, in which Carbios now holds a majority stake alongside the SPI fund operated by Bpifrance.
