Carbios acquires the necessary skills to succeed in its industrial expansion and strengthens its management committee.



Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end of life of plastic and textile polymers, announces the appointment of two new members to its Executive Committee: Lionel Arras, Industrial Development Director, and Mathieu Berthoud, Sourcing and Public Affairs Director.

Lionel Arras joined the Carbios teams in 2021 to support the industrial growth of enzymatic PET recycling technology as Director of Industrial Development. He was appointed to the Company’s Executive Committee on May 2. A graduate engineer from ENSIC Nancy and holder of an MBA from the Ecole Supérieure de Management de Lyon, Lionel Arras has more than 25 years of experience in the field of process engineering and the chemical industry. At Carbios, he now leads a team of around fifty people mobilized around three main areas:

– the industrial demonstrator, inaugurated last September in Clermont-Ferrand,

– technological development,

– the first Reference Unit project, installed on the Indorama Ventures site in Longlaville, Meurthe-et-Moselle, France.

Lionel Arras, Director of Industrial Development at Carbios: “After the successful start of our industrial demonstrator in Clermont-Ferrand, we are continuing our scale-up with the construction of the world’s first enzymatic recycling plant in Longlaville, France. Its launch, scheduled for early 2025, will process 50,000 tonnes of post-consumer PET waste, the equivalent of 2 billion bottles.. It gives me great pride to be able to support Carbios in this phase of strategic development.

Mathieu Berthoud will join Carbios as Sourcing and Public Affairs Director on June 1, 2022. With more than 30 years of experience, including 10 years at Rhodia (now Solvay) and more than 20 years at Suez, in various development positions commercial or subsidiary management, he was most recently Technical and Performance Director of the Group’s recycling and recovery activities. A scientist by university education, he also holds an MBA from HEC Paris. At Carbios, he will be responsible for securing the supply of PET waste to the future Longlaville reference plant and the other industrial sites that will follow. He will also manage the public affairs of the Company.

Mathieu Berthoud, Sourcing and Public Affairs Director at Carbios, said: “I am delighted to join the Carbios team. It is a great pride for me to participate in this ambitious and meaningful project. While the enzymatic PET recycling technology is already a concrete circular economy solution, the the establishment of a dedicated sector will also be key to achieving the sustainable development objectives of future Carbios licensees.

Emmanuel Ladent, CEO of Carbios, said: “I am very pleased with the appointments of Lionel Arras and Mathieu Berthoud to the Executive Committee of Carbios. These appointments reinforce the Group’s structure and expertise at an exciting stage in our development. Their experience will be complementary and necessary for the successful large-scale deployment of our disruptive technology. In order to ensure the achievement of the ambitious objectives that we have set ourselves for the years to come, we are continuing to strengthen our management teams.

About Carbios

Carbios, a green chemistry company, develops biological and innovative processes representing a major innovation in the end of life of plastics and textiles. Through its unique approach combining enzymes and plastics, Carbios aims to meet new consumer expectations and the challenges of a broader ecological transition by taking up a major challenge of our time: plastic and textile pollution.

Created in 2011 by Truffle Capital, Carbios’ mission is to provide an industrial solution for the recycling of PET plastics and textiles (dominant polymer in bottles, trays, polyester textiles). 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 equivalent quality to virgin. This PET innovation, the first of its kind in the world, was recently recognized in a scientific article published in the prestigious journal Nature. Additionally, Carbios is working hand in hand with multinational brands – such as L’Oréal, Nestlé Waters, PepsiCo and Suntory Beverage & Food Europe – to implement its technology and lead the transition to a true circular economy.

The Company has also developed an enzymatic biodegradation technology for single-use plastics based on PLA (a biobased polymer). This technology makes it possible to create a new generation of plastics that are 100% compostable under domestic conditions, integrating enzymes into the heart of the plastic product.
