health and beauty retail chain in Korea. “The new cosmetic case was developed by combining aPHA with PLA to replace acrylonitrile butadiene styrene [ABS]. Some developed countries and leading cosmetic brands are actively making efforts to replace ABS, which is a petroleum-based, non- biodegradable plastic, and the PLA/aPHA blend introduced an eco-friendlier alternative. More recently, we worked with Banila to develop the world’s first 100% biobased cosmetic jar using aPHA technology.” This October, CJ Biomaterials was awarded a German 2023 Red Dot Design Award for the PHA Head-Up Toothbrush, developed in collaboration with Australian eco-designer company Revelop. The toothbrush was a winner in the ‘Sustainable’ category within the Design Concept discipline. “We hope recognition in the Red Dot Design Award will help to promote the advantages of PHA and accelerate the commercialisation of PHA-based products by demonstrating the versatility of its appli- cations in various end products,” says Max Sene- chal, Chief Commercial Officer of CJ Biomaterials.
Wood solutions Produced in Finland using wood cellulose, Woodly is a part renewable polymer said to display charac- teristics similar to conventional fossil plastics while being both carbon neutral and recyclable. The mate- rial, which is 40-60% bio-based depending on the grade, was selected recently by several entertain- ment venues for production of reusable drinking glasses as part of a programme to promote sustain- ability in the leisure and tourism industry. “With these reusable glasses, we’re not only
reducing our environmental footprint but also providing our customers with a greener option that contributes to a more sustainable nightlife culture,” says Kimmo Sirviö, Chairman of the Board of SKA-Ravintolat, a nightclub involved in the scheme. Woodly currently offers two product lines. The 100 series grades are said to be suitable for both blown film and cast film extrusion. Films are clear and transparent and can be thermoformed. The 200 series are developed for injection moulding and also offer transparency and clarity. Woodly materials are said to be suitable for food contact applications but are not compostable. Hromatka Group’s Guzman Polymers was appointed distributor for Woodly in Spain, Portugal, Italy and Turkey earlier this year. Bio-based compounds are not just restricted to
PLA and PHA — a number of performance polyam- ides are also either fully or partly bio-based. Turkish compounder Eurotec’s Techmidbio line of part of

fully bio-based engineering compounds are based on polyamides such as PA5.6, PA5.10, PA11, PA6.10, PA10.10 and PA10.12. Developed as replacements for PA6 and PA66 in automotive and white goods applications, the company says bio-based content depends on the matrix material and reinforcement type. Examples include Tecomidbio NI40 CR30 BK111
HS, which is a PA6.10 reinforced with 30% recycled carbon fibre formulated for automotive applica- tions, and Tecomidbio NR30 NL CA, an unfilled and heat stabilised PA11 offering high dimensional stability, low moisture absorption and low density. The company has also developed part bio-based grades offering the high hydrolysis required for connectors and housings used in electric vehicle cooling systems. These include Tecomidbio NQ40 GR30 NL HS 30% glass fibre reinforced PA5.10 and Tecomidbio NI40 GR30 NL HS 30% glass fibre reinforced PA6.10. Tecobio is a fully biodegradable product line based on PLA, PBS, TPS and PBAT blends with natural or synthetic additives and reinforcements. Tecobio PL30 WR30 NL is a 30% wood filled PLA designed for use in pens, toothbrushes and cutlery. Tecobio PL40 MF25 NL 01 is a 25% mineral filled PLA/PBS blend that developed for cutlery requiring higher heat resistance.
