CARBIOS opens a new biological pathway with its one-step PLA production process

CARBIOS (NYSE Alternext Paris : ALCRB/ Eligible PEA-PME), an innovative green chemistry company specializing in breakthrough technologies dedicated to the recovery of plastic waste, today announced that it has taken a major step forward with the validation of its in vivo enzymatic polymerisation process of lactic acid into a high-molecular weight homo-polymer of PLA.

 

Among bio-sourced polymers, PLA is currently one of the most promising on the market due to its remarkable properties, which satisfy a large range of applications[1]. With a world-production capacity of 190 000 tons per year[2], margins for progress remain considerable. In 2020, PLA production capacity could reach 400 000 tons worldwide, corresponding to a fluid growth rate of 15% per year[3].

 

On an industrial scale, current processes for the production of PLA require an expensive intermediary step consisting of the condensation of lactic acid (oligomerisation and cyclisation) into a lactid (a cyclic diester). This intermediary component must then be purified and chemically polymerized to obtain PLA.

 

The technological breakthrough brought by CARBIOS cuts out this intermediary step and produces, with greater competitiveness, a high-molecular weight homo-polymer of PLA directly from lactic acid. “My partners and I are proud to have successfully met this scientific challenge, and to have developed the first microorganism capable of producing a 100% PLA polymer of high-molecular weight,” says Alain Marty, Chief Scientific Officer of CARBIOS.

 

This result was achieved with help from the Toulouse-based teams of the INRA and the INSA (TWB and the LISPB), partners of CARBIOS as part of the collaborative research and development program THANAPLASTTM. “To conceive an original metabolic pathway to synthetize PLA was a true scientific and technological challenge of industrial biology,” says Pierre Monsan, Director of TWB.

 

This milestone will enable CARBIOS to continue to the pre-pilot scale of this PLA production process within the initial deadline, thus allowing the possibility of considering potential agreements with industrials of the sector in the very near future.

 

The technologies applied to the production of PLA could also be used for the production of other biopolymers, notably other polyesters like polyhydroxyalkanoates (PHAs). This market, currently a low-tonnage market, has an estimated growth potential of 28% between now and 2018[4] and addresses the same concerns as PLA production: produce a bioplastic that is competitive with conventional plastics in terms of cost and performance and will limit the use of fossil- and food-based resources.

 

At year-end 2015, CARBIOS’ intellectual property portfolio was comprised of 5 patent families protecting the processes for the production of bio-polymers and 17 patent families for all the processes developed by the company.

 

Since the launch of the THANAPLASTTM project, we have announced our will to develop, by biological means, a bioprocess for the production of PLA so to increase competitiveness of one of the most promising bio-sourced polymers on the market. Today, it has become a reality that will enable us to work with large industrials so to establish our technology in a quickly growing market. This innovation, a result of our collaborative model, is perfectly in line with the recent direction outlined by the French “Energetic Transition Law” for green growth and the emergence of bio-sourced products,” says Jean-Claude Lumaret, CEO of CARBIOS.

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.
