First production of virgin PET from post-consumer plastic bottles treated by enzymatic hydrolysis

Clermont-Ferrand, France, October 12, 2017 (06:45 AM CEST) CARBIOS (Euronext Growth Paris: ALCRB), pioneer company in the field of bioplasturgy, today announces that it has taken a new step forward with the production of virgin PET made out of terephthalic acid coming from its biorecycling process of post-consumer PET plastic bottles.

CARBIOS previously demonstrated that it had successfully synthetized PET oligomers made out of terephthalic acid coming from its biorecycling process of PET plastic bottles. This was the first step towards the production of PET.

The following step consisting in the synthesis of virgin PET made out of these oligomers has now been completed confirming by then the potential of CARBIOS’ technology for the recycling of plastic bottles waste into virgin PET polymers.

Alain MARTY, Chief Scientific Officer of CARBIOS comments: “We have met a new challenge by demonstrating that enzymatic depolymerization applied to PET bottles enables the virtuous cycle of a return to virgin PET. Our next short-term goal is now to demonstrate that this virgin PET is suitable for the production of new bottles, thus paving the way to circular economy for PET plastic products.”

Jacqueline LECOURTIER, President of CARBIOS Scientific Committee and member of the French National Academy of Technologies declares: “The original process developed by CARBIOS to recycle PET, main component of plastic bottles massively used by the food industry, is a major innovation. CARBIOS demonstrates the high potential of enzymatic recycling applied to plastic waste in terms of efficiency and environmental friendliness and opens promising prospects for the treatment of a wide range of this type of waste.”

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:

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