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 are designed to meet environmental and sustainable development issues faced by global industrial players. Since its creation in 2011, CARBIOS has developed two industrial bioprocesses dedicated to the biodegradation and the biorecycling of polymers. These innovations, which are 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, enzymes, technologies, and bioprocesses via the concession of licenses, directly or via joint ventures to major industrial players in the sectors that can make use of the Company’s innovative technologies. For instance, CARBIOS created in September 2016 the joint-venture CARBIOLICE, in partnership with Limagrain Ingrédients and the SPI investment fund run by Bpifrance. This company, in which CARBIOS holds a controlling share, will market the first technology licensed by CARBIOS by producing an enzymatic additive making PLA-based plastics (films, bags, packaging) fully compostable in domestic conditions.

Since its creation, CARBIOS benefits from the financial support of the leading European venture capital firm Truffle Capital. CARBIOS was granted the label “Young Innovative Company” by Bpifrance (former OSEO) and is eligible for investments by private equity mutual funds (FCPIs).
