Overview
Polyethylene Furanoate (PEF)
PEF is a 100% plant-based, recyclable polymer that stands out as a next-generation polyester, offering significant advantages over traditional plastics like PET (Polyethylene Terephthalate). Developed by Avantium, PEF aims to replace conventional fossil-based materials and is positioned as a sustainable alternative across multiple industries.
Key Properties:
Superior Barrier Properties:
PEF provides excellent barrier protection against CO2 and oxygen, leading to a longer shelf life for packaged products. This makes it particularly suitable for beverage and food packaging.
Higher Mechanical Strength:
PEF’s superior mechanical properties allow for the production of thinner packaging, reducing the amount of material needed, which leads to lower resource usage without compromising performance.
Versatility:
The polymer can be used across a range of applications, including packaging, textiles, and films, making it a versatile material for various industries.
Competitive Position:
PEF competes with traditional packaging materials such as glass, aluminium, paper, and PET, offering a bio-based, recyclable alternative with superior functional qualities.
Furan-2,5-dicarboxylic Acid (FDCA)
FDCA is the key building block for producing PEF and is created using Avantium’s proprietary YXY Technology. This technology catalytically converts plant-based sugars into FDCA, which can then be polymerized to produce PEF.
Key Aspects:
YXY Technology:
Avantium’s process involves the catalytic conversion of renewable plant-based sugars into FDCA, ensuring that the production of PEF is sustainable from start to finish.
"Sleeping Giant" of the Chemicals Industry:
FDCA has been dubbed the "sleeping giant" because of its potential to revolutionize the chemical industry. Beyond PEF, it can be used to produce a wide range of sustainable polymers, including polyesters, co-polyesters, polyamides, and polyurethanes.

Production and Commercialization
Avantium is at the forefront of bringing PEF and FDCA to market, with significant advancements in production and regulatory approval. The company has successfully demonstrated its YXY Technology at a pilot plant in Geleen, Netherlands, proving the feasibility of scaling up production to a commercial level. This success has paved the way for the construction of the world’s first commercial FDCA production facility in Delfzijl, Netherlands. The flagship plant, set to open officially on October 22, 2024, will have a capacity of 5 kilotons and is designed to supply FDCA for a variety of applications. This marks a major milestone in the commercialization of bio-based materials, showcasing Avantium's commitment to making sustainable chemicals widely accessible.
Applications for PEF
Packaging
PEF’s excellent barrier properties make it ideal for food and beverage packaging, particularly for products like soft drinks, water, juices, and dairy. It offers better protection against CO2 and oxygen, extending the shelf life of perishable goods. Additionally, its high mechanical strength allows for thinner packaging, reducing material use.
Beyond beverages, PEF can be used for packaging other consumer goods, such as cosmetics and personal care products, where sustainability and product integrity are crucial.
Textiles
PEF can be spun into fibres for use in textiles, making it a potential eco-friendly alternative to polyester. It can be used in clothing, upholstery, and other fabric-based products. PEF's bio-based origin and recyclability appeal to brands looking to make their textiles more sustainable.
Films
The high barrier properties and flexibility of PEF also make it suitable for films used in flexible packaging, laminates, and labels. This can help in industries like food packaging, where maintaining freshness and quality is essential.
Rigid and Semi-Rigid Containers
PEF can be moulded into rigid and semi-rigid containers for various uses, including packaging for food, personal care, and household products. Its durability and sustainability make it an attractive option for companies aiming to reduce their carbon footprint.
Applications for FDCA
Production of PEF
The primary use of FDCA is to produce PEF, where it replaces the fossil-based terephthalic acid used in PET. FDCA’s bio-based origin allows PEF to maintain its eco-friendly profile, making it a key player in sustainable plastics.
Other Sustainable Polymers
Beyond PEF, FDCA can be used to create various other bio-based polymers, including polyesters, co-polyesters, polyamides, and polyurethanes. These polymers can be applied in a wide range of industries, from automotive and electronics to textiles and coatings.
Adhesives and Coatings
FDCA’s chemical properties allow it to be used in the production of sustainable adhesives and coatings. This could offer new eco-friendly options for industries such as construction, packaging, and consumer goods, where adhesives play a crucial role.
Automotive and Electronics
FDCA-based polymers can be applied in the automotive and electronics industries as lightweight, durable, and heat-resistant materials. This helps in reducing the overall weight of components, leading to improved energy efficiency, particularly in electric vehicles.
Partnerships
The PEFerence Consortium
Avantium leads the PEFerence consortium, a group of companies that joined forces to establish the entire value chain for PEF. This consortium includes partners from different stages of the supply chain, such as Synvina (a joint venture with BASF until 2018), ALPLA, and Mitsui. The aim is to produce and commercialize 100% plant-based PEF bottles and packaging. The collaboration covers everything from feedstock supply to PEF production and its use in packaging, ensuring a seamless and scalable approach to bringing PEF to market.
Coca-Cola and Danone
Two of the world's largest beverage companies, Coca-Cola and Danone, have partnered with Avantium to develop PEF bottles as part of their sustainability initiatives. Both companies have expressed interest in using bio-based packaging to reduce their carbon footprints and have supported Avantium’s efforts to create PEF as a viable alternative to PET. These partnerships are significant as they help validate the commercial potential of PEF and encourage broader adoption across the beverage industry.
Carlsberg
Avantium has also collaborated with Carlsberg on developing the Green Fiber Bottle, which is a paper-based beer bottle with an inner lining made from PEF. This innovation aligns with Carlsberg’s sustainability ambitions and shows how PEF can be used beyond typical plastic applications, offering a bio-based solution for various packaging formats.
Toyobo
Japanese chemical company Toyobo has partnered with Avantium to explore the use of PEF for flexible packaging applications. The collaboration focuses on developing PEF films for packaging food, cosmetics, and personal care products, leveraging Toyobo’s expertise in high-performance films to expand the range of applications for PEF.
Origin Materials
In 2022, Avantium entered into a collaboration with Origin Materials, a company specializing in carbon-negative materials. The partnership focuses on developing FDCA-based materials that can be used in a variety of applications, such as textiles, coatings, and automotive parts. This collaboration further broadens the scope of FDCA’s market potential.
Sustainability Impact
PEF and FDCA offer significant environmental benefits, playing a key role in promoting a more sustainable and circular economy. Third-party, peer-reviewed, and ISO-certified life cycle assessments have shown that PEF can achieve up to a 62% reduction in greenhouse gas emissions over the life cycle of a 500 ml PET bottle. This impressive reduction demonstrates the potential of PEF to lower carbon footprints and support sustainability efforts across industries. Furthermore, Avantium's production process relies on renewable plant-based feedstocks, which helps minimize the environmental impact compared to traditional fossil-based alternatives.
Recent Developments
Avantium has achieved several important regulatory and developmental milestones, paving the way for the broader adoption of PEF. On October 8, 2024, the U.S. Food and Drug Administration (FDA) granted Food Contact Notification (FCN) approval for PEF, allowing it to be used in food contact articles in the United States. This approval complements existing European food contact certifications, enabling PEF to be utilized as packaging material for all food types across major markets.
Commercial quantities of FDCA and PEF are expected to be available from early 2025. For those interested, it is best to contact Avantium directly to discuss your specific needs and potential applications for PEF or FDCA.
