CARBIOS announces grant of a second major U.S. patent focused on the recycling of complex PET plastic waste

  • CARBIOS’ recycling technology is the first to enable the enzymatic treatment of all forms of PET plastic waste, including complex plastics and polyester fibers
  • CARBIOS now holds 30 patent families worldwide, 11 related to its PET recycling technology

 

Clermont-Ferrand, France, June 20, 2019 (06:45 AM CEST)CARBIOS (Euronext Growth Paris: ALCRB), a company pioneering new, bio-industrial solutions to reinvent the lifecycle of plastic and textile polymers, announced today that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for an additional U.S. patent for CARBIOS’ proprietary process of recycling PET plastic waste.

This patent application (US 2017/114205) recognizes CARBIOS for its invention of a proprietary method of recycling complex plastics, including colored, opaque and multi-layer products containing a mix of polyethylene terephthalate (PET), and at least one additional component (e.g., polyolefins, vinyl polymers, rubber, cotton or nylon fibers, paper, aluminum, starch, wood, etc.).

Many plastic products are made of multiple polymers or components that are mixed together or organized as layers. This makes them non-recyclable using current thermo-mechanical processes where mono-material waste is required. Traditional pretreatments, such as sorting, reach a limit as they are not capable of separating PET from the other components. CARBIOS’ technology overcomes these issues given its:

  • Stable and reliable depolymerization of PET regardless of the composition of mixed PET plastic products or the presence of other components or polymers;
  • Recovery of PET building blocks (PTA and MEG monomers) from complex plastics; and
  • Separation and purification for a suitable use in any original application.

This patent is the second one in the U.S. that has been applied to CARBIOS’ infinite recycling technology, and it protects CARBIOS’ innovation through 2033. In addition to this patent, CARBIOS owns 116 titles worldwide representing 30 patent families, six of which protect its proprietary method of recycling in full, and five of which are related to enzymes that degrade PET.

Jean-Claude Lumaret, CEO of CARBIOS, comments, “This patent confirms CARBIOS’ unique expertise and leadership in developing an infinite recycling solution for all kinds of PET waste, particularly types which are barely treatable using traditional recycling processes. Demand for technology that facilitates a circular economy is growing rapidly and we are at the forefront of providing global players an efficient alternative that protects the environment.”

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.
