Avantium has developed its YXY® Technology to produce FDCA (furandicarboxylic acid), the key building block for the 100% plant-based and recyclable plastic material PEF (polyethylene furanoate). PEF has an attractive combination of sustainability and performance characteristics for a wide range of applications, including bottles, packaging and textiles. Avantium is currently constructing the world’s first commercial facility for FDCA in Delfzijl, the Netherlands, which is expected to be operational in 2024, enabling the commercial market launch of PEF.
PEF can be used in fully plant-based monolayer PEF bottles, but also has advantages in combination with PET. For example, PEF can be used in multilayer PET (polyethylene terephthalate) bottles as a barrier material, when the required shelf life cannot be guaranteed by a single layer of PET. Currently, many multilayer PET bottles include nylon as barrier, which is known to give issues when recycled along within the PET recycling stream. Due to its excellent barrier properties and its close resemblance to PET, a PEF layer is an excellent alternative, having a very limited influence on its recycling process.
For the APR Critical Guidance testing in the US, multilayer PET/PEF bottles containing 7 wt% and 10 wt% of PEF, were first evaluated by a third-party (Plastics Forming Enterprises LLC) and then reviewed by an independent committee, appointed per the APR Recognition Operating Procedures. Avantium demonstrated the compatibility with standard PET recycling practices, without impacting the physical properties of the recycled PET. It was concluded that both types of multilayer PET/PEF bottles meet or exceed the most challenging test conditions and strictest APR Critical Guidance criteria.
