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.

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).
