CARBIOS: new success with the synthesis of PET oligomers from biorecycled terephthalic acid

Clermont-Ferrand, France, June 13, 2017 (6:45 AM CEST) – CARBIOS (Alternext Paris: ALCRB), pioneer company in the field of bioplasturgy, announces that it has taken a new step forward with the production of  PET oligomers made out of terephthalic acid coming from its biorecycling process of PET plastic bottles.

The synthesis of PET is carried out in two major steps:

  • The first, considered to be the most critical, consists in the synthesis of PET oligomers from monomers of terephthalic acid and mono ethylene glycol.
  • The second allows the synthesis of PET by polycondensation of the oligomers previously obtained.

 By succeeding in this first step, CARBIOS demonstrates that it is now possible to use PET plastic waste rather than fossil resources for the synthesis of PET oligomers.

CARBIOS previously demonstrated that it had successfully depolymerized PET bottles into its initial monomers. A first scale up of the process has since been performed. After a proof of concept at the scale of one hundred milliliters, this depolymerization was carried out in reactors of 5 and 100 liters. At such last scale, 20 kilos of PET have been treated and depolymerized at 90%. Performances of the depolymerization process were perfectly identical regardless of the reactors volume, showing by then the strength of this technology. At the end of the depolymerization process, the terephthalic acid produced has been collected and purified. Its purity reaches a level above 99% and analytic technics of reference do not allow to make any difference with commercial terephthalic acid produced from oil.

We have demonstrated that the purity of the terephthalic acid obtained through our original enzymatic process allows the efficient synthesis of PET oligomers. This is a new important step that reinforces the industrial potential of our technology. We are very confident in the forthcoming demonstration of a complete recycling of PET waste into new PET bottles of same quality as the original products. It is now our short-term goal before operating, with key players of the PET value chain, a pilot plant and launching the industrial demonstration of the process” comments Alain MARTY, Chief Scientific Officer of CARBIOS.

About Carbios

Carbios is a green chemistry company whose innovations help address the environmental and sustainable development challenges facing manufacturers. Since its creation in 2011 by Truffle Capital, the Company has developed, through biotechnology, two industrial processes that revolutionize the biodegradation and recycling of polymers. These innovations, a world first, optimize the performance and lifecycle of plastics and textiles by exploiting the properties of highly specific enzymes.

Carbios’ economic development model is based on the industrialization and commercialization of its products and/or enzymes, technologies and bioprocesses through license concessions directly or through joint ventures to major industrial players or sectors concerned by the Company’s innovations. As such, Carbios created the joint venture Carbiolice in September 2016, in partnership with Limagrain Ingredients and the SPI fund operated by Bpifrance. This company, of which Carbios has majority control, will exploit the first technology licensed by Carbios by producing enzymatic granules for the production of biodegradable and biobased plastics.

Carbios benefits from the qualification “Innovative Company” of Bpifrance allowing the eligibility of the Company’s securities for the investment of Mutual Funds Placement in Innovation (FCPI). For more information, please visit: www.carbios.fr

Carbios is eligible for the PEA-PME, a government program allowing French residents investing in SMEs to benefit from income tax rebates.
