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 is a green chemistry company whose innovations are designed to meet environmental and sustainable development issues faced by global industrial players. Since its creation in 2011, CARBIOS has developed two industrial bioprocesses dedicated to the biodegradation and the biorecycling of polymers. These breakthrough innovations, which are a worldwide premiere, leverage the highly specific properties of enzymes to optimize the performances and the life cycle of plastic and textile materials. CARBIOS’ economic development model is based on the industrialization and commercialization of its products, enzymes, technologies, and bioprocesses via the concession of licenses, directly or via joint ventures to major industrial players in the sectors that can make use of the Company’s innovative technologies. For instance, CARBIOS created in September 2016, the joint-venture CARBIOLICE, in partnership with Limagrain Céréales Ingrédients and the SPI investment fund run by Bpifrance. This company, controlled by CARBIOS, will operate the first patented enzymatic biodegradation technology licensed by CARBIOS by producing enzymated pellets to be used for the production of a new generation of bio-sourced and biodegradable plastics. Since inception, CARBIOS benefits from the financial support of the leading European venture capital firm Truffle Capital. CARBIOS was granted the label “Young Innovative Company” by Bpifrance (former OSEO) and is eligible for investments by private equity mutual funds (FCPIs).
