Carbios Granted U.S. Patent Focused on Recycling PET Waste

France-based Carbios announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for an additional U.S. patent for Carbios’ process of recycling polyethylene terephthalate (PET) plastic waste.

This patent application recognizes Carbios for its invention of a proprietary method of recycling complex plastics, including colored, opaque and multilayer products containing a mix of PET and at least one additional component (e.g., polyolefins, vinyl polymers, rubber, cotton or nylon fibers, paper, aluminum, starch, wood, etc.).

Carbios’ technology includes:

This patent is the second one in the U.S. that has been applied to Carbios’ recycling technology and 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.

“This patent confirms Carbios’ unique expertise and leadership in developing an infinite recycling solution for all kinds of PET waste, particularly types that are barely treatable using traditional recycling processes,” said Jean-Claude Lumaret, CEO of Carbios, in a statement. “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.”
