Slavik Kasztelan, Program manager “Biomass to chemicals” and “Petrochemicals” of IFPEN:

"IFP Energies nouvelles and its subsidiary Axens are eager to tackle the challenge of bringing to the market competitive processes for recycling plastics and to produce bio-based polymer precursors and make circular economy a reality. We are therefore glad to join the SIG efforts to accelerate the success of monomer recycling technologies".

CARBIOS develops an industrial solution based on the use of highly specific enzymes that fully breaks down post-consumer PET plastics & textiles into their original building blocks (monomers), which can be used to produce new virgin quality plastics, such as bottles and packaging or textiles. Based on circular economy principles, this sustainable approach brings a game-changing answer to preserve the environment and fulfill global brands and consumers demand for sustainable solutions.


CuRe Technology- Polyester Rejuvenation. CuRe Technology wants to CuRe polyester waste, join the polyester recycle revolution. CuRe Technology have decades of experience in virgin polyester, mechanical recycling, waste preparation, materials science and engineering. Together they create and accelerate the positive impact. To recycle infinitely. Again and again and again.

ChemPET - “chemical recycling” process capable of handling almost all the currently non-recoverable PET based waste. Through a chemical reaction, the PET, present in the pre- and post-consumer waste, is reacted selectively with ethylene glycol and transformed into an intermediate product called BHET (bis-hydroxy-ethylene-terephthalate) which, if adequately purified , can be used again for the production of PET in place of raw materials of fossil origin.

Depoly's recycling technology uniquely deals with pre- / post-consumer and post-industrial PET and polyester streams, typically turned down by the conventional recycling system, such as those containing mixed plastics, mixed colors, dirty plastic waste streams, as well as fabrics and fibers, recycling them back into their original monomers (PTA and MEG) of the same quality as the fossil-fuel-based incumbents, meaning customers no longer have to choose between PET quality and sustainability. Operating under room temperature and standard pressure, the DePoly process doesn't require pre-washing, sorting, melting, or separation of other materials, unlike most of the technologies out there. Ultimately, it not only offers a circular solution for plastic waste but is also energy efficient and reduces the carbon footprint originating from PET plastic production.


Dupont Teijin Films have consistently driven innovation in the polyester industry from the initial invention and development of the polymer in the 1940s through to their current position as the world’s largest supplier of heat sealable BOPET films driving the move to recyclable mono PET tray and lid structures. With the launch of the new LuxCR™ process, DuPont Teijin Films are addressing some of the limitations of mechanically recycled PET by depolymerising the material back into the monomer unit bis(2-hydroxyethylterephthalate) or BHET before converting into a wide range of BOPET films covering applications as diverse as food packaging, labels, solar panel back sheets, ID cards and more.

The upcycling of mechanically recovered PET marks an important step forward in the drive towards a more sustainable future for the packaging industry where depolymerisation is used to restore the material properties to ensure plastic to plastic recycling, providing a balance between the amount of waste material generated and the amount of high value end use applications that it can be recycled into. Steven Davies, Market Manager EMEA Packaging: "We are very proud to be founding members of the Monomer Recycling SIG and we believe the LuxCR™ process launch marks an important milestone in the future of monomer recycling which can be used as a case study in the upcycling of recycled PET, ultimately opening up new waste streams and high value end markets for recycled polyester."

Eastman’s innovation-driven growth strategy, underpinned by creating value through sustainability and a commitment to enhancing the quality of life in a material way, is driving the company’s efforts to advance the circular economy by finding new uses for products or materials otherwise reaching end of life. The company announced plans to launch an advanced circular recycling technology using the process of methanolysis to break down polyester waste that cannot be recycled by current mechanical methods into basic polymer building blocks that can be reintroduced as new polyester-based polymers, delivering a true circular solution.

Eastman also introduced a second innovation called carbon renewal technology, which is capable of recycling some of the most complex plastic waste, including non-polyester plastics and mixed plastics that cannot be recycled with conventional recycling technologies. With this new recycling technology, materials such as flexible packaging and plastic films, among others, can be diverted from landfills.

Board Chair and CEO Mark Costa said, “Eastman has the technology, the innovation power and the people to make a difference. Eastman is now uniquely positioned to deliver two powerful innovation solutions that target different plastic waste streams that pose complex challenges. Plastics are used in so many important ways. But because some don’t have good end-of-life solutions or are discarded, the world is facing a problem of significant magnitude.”

“Eastman is embracing its stated purpose of enhancing the quality of life in a material way for people around the world,” Costa added. “This translates not only to producing superior materials for the products consumers use daily, but also contributes in a meaningful way to a circular economy – an economy where we reuse and repurpose our resources, so they retain their value for as long as possible.”


Equipolymers is a company dedicated to the manufacture and marketing of Polyethylene Terephthalate (PET). It is a wholly owned subsidiary of EQUATE Petrochemical Company (EQUATE), a global producer of petrochemicals and the world’s second largest producer of ethylene glycol (EG).

Dirk Koehlmann, Lead Account Manager: “With its Viridis 25, Equipolymers is launching a new food-contact PET grade using up to 25 % chemically recycled PET as feedstock, which reduces the need for virgin PET with benefits for business, the environment and the community. This advancement from EQP takes the world closer to closing the loop in the circular economy, helping brand owners to meet the guidelines of the European Plastic Strategy while driving an increase in plastics recycling.”

Gr3n SA is a Swiss company established in 2013. The company developed an innovative process, based on a new application of microwave technology to provide an efficient chemical recycling process of PET and polyester textile allowing an industrial implementation of this recycling method. The robustness of the whole process allows to treat highly contaminated materials upcycling the PET recycling. The recycling process of gr3n produces the same monomers used for conventional synthesis of PET exploiting a full integration with the existing value chain of PET. The process is economically competitive with oil-based production of PET but creating a huge benefit for the environment.
