producer to receive ISCC Plus certification for bio-circular ethylene monomer in its supply chain. It says it covers, in principle, all EVOH variants that it produces at its plant at Antwerp in Belgium. Kuraray also showed its Septon Bio series of
TPEs, which are based on hydrogenated styrene farnesene block copolymers (HSFC) synthesised from beta-farnesene, a monomer derived from sugarcane. Bio-based content varies up to 80% depending on the specific grade. Compared to conventional styrenic block copolymers, Septon Bio grades are claimed to reduce greenhouse gas emissions by up to 33% as well as improving properties such as oil retention, weatherability and compression set.

mented each other in their effects in both filled and unfilled bioplastic systems. When used together, the processing and performance properties of bioplastics could be optimally adapted to specific requirements. Depending on the grade used, Vinnex showed a positive influence on polymer melt or mechanical properties. In the samples tested, Genioplast acted as a booster, enhancing the effects achieved with Vinnex. In several cases, the silicone additive also improved properties that Vinnex on its own did not influence.
Mass balance Bio-Fed – an expert in biodegradable and bio- based plastics – showcased a number of materials at K2022, including a mass-balanced PP compound called M-Vera. Most M-Vera bioplastics are also biodegradable, with many of them either partially or fully bio- based. They are suitable for various different processing technologies including blown film, extrusion and thermoforming. The range also includes a mulch film type that is soil degradable according to EN 17033. If offers OK compost Industrial certified products
– with different proportions of renewable content – for extrusion and thermoforming,. These have different mechanical properties that are tailored for each specific application. They can be processed with standard equipment, into sheets, films and profiles.
Circular EVOH Kuraray introduced its Bio-Circular ethylene-vinyl alcohol (EVOH) at K2022, the latest addition to its line of Eval EVOH barrier resins for packaging applications. The company says it is the first EVOH copolymer

PLA collaboration Total Energies Corbion has entered a long-term collaborative arrangement for application develop- ment and the supply of its Luminy PLA to South Korea-based BGF. Both companies are focused on the development and production of biodegrad- able materials and products. BGF recently launched a single-use, noodle cup which is aesthetically pleasing, bio-based and compostable. The lightweight, foamed cup mini- mises the use of materials and is being produced using high heat Luminy PLA as a base resin. The cup is a joint development between the companies, with more developments to follow in future. “Bringing more environmentally friendly prod- ucts to the Korean market remains a key focus of our business,” said Hong Jung-Gook, CEO of BGF. Thomas Philipon, CEO of Total Energies Cor-
bion, added: “The biopolymers market is experi- encing strong growth – and customers are request- ing innovative solutions tailor-made to their market needs.”
