CARBIOS pursues its genuine revolution in the biorecycling of PET based plastics

  • Time of PET hydrolysis reduced by one-third: 97% conversion in 16 hours
  • Pilot-scale of PET hydrolysis now carried out in a reactor of 1,000 liters

 Clermont-Ferrand, France, July 19, 2018 (06:45 AM CEST)CARBIOS (Euronext Growth Paris: ALCRB), pioneer company in the field of bioplasturgy, announces new results in the optimization of its biorecycling process of waste PET plastics. The hydrolysis of PET plastics into their original building-blocks now reaches a conversion rate of 97% in only 16 hours.

Last April, CARBIOS had already divided by three the time of PET hydrolysis by achieving a conversion rate of 97% in 24 hours. These new results confirm and strengthen the industrial competitiveness of CARBIOS enzymatic biorecycling process for the transformation of waste PET plastics into new virgin plastics.

At a time when the largest global players have shown a strong commitment to incorporate up to 100% of postconsumer recycled plastics in their products by 2025, CARBIOS is at the forefront of meeting these ambitions and to engage a genuine revolution in the lifecycle of plastic products. By pursuing the optimization of its proprietary enzymes, with the teams of the Laboratory of Biological Systems and Process Engineering (LISBP) and Toulouse White Biotechnology (TWB), CARBIOS reaches a unprecedent conversion rate in the enzymatic recycling of waste PET plastics. These results come along with the PET hydrolysis scale-up at pilot stage, which is now carried out in a reactor of 1,000 liters, in collaboration with CRITT Bio-Industries.

Alain MARTY, Chief Scientific Officer of CARBIOS comments: “Our solution will enable manufacturers to produce bottles and plastic packaging made at 100% from postconsumer recycled plastics. It is a real revolution that we are engaging with this biological pathway. Enzyme performance optimization is our core business and our latest generation of enzyme is even more active and thermostable. The kinetics reached will allow us to take another important step by developing a process with improved economic performance.

Martin STEPHAN, Deputy CEO of CARBIOS adds: “These developments are notable improvements. They reinforce the attractiveness of our technology in a market strongly in demand of eco-friendly solutions. CARBIOS now has all the strengths it needs to become a key player in the circular economy. We will be there to meet brand-owners sustainability commitments.

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.
