Carbios, a company pioneering new, bioindustrial solutions to reinvent the lifecycle of plastic and textile polymers, announced that the United States Patent and Trademark Office (USPTO) has granted Carbios a patent on its proprietary process for PET recycling from plastic waste using enzymatic technology.

The patent granting (US 10,124,512) recognizes the company for its invention of a method for recycling polyethylene terephthalate (PET) from a mixture of plastic waste products using enzymes, to specifically depolymerize PET into its basic monomers. The monomers can then be transformed back into usable polymers for the manufacturing of new plastic products, such as bottles and packaging.

This patent, filed back in November 2013 by Carbios, is the first granted patent in the U.S. applied to this innovative PET plastic recycling method. This U.S. patent protects the core process and technology until 2033. Beside the acceptance of this patent, the company currently holds 98 titles worldwide representing 29 patent families, six of which protect in full its proprietary method of biorecycling and five of which are related to PET degrading enzymes.
