made with mass balance attributed renewable feedstock content. The NAS ECO 21 BC70 styrene acrylic copolymer grade was selected by UK based Eco-inject for a new generation of single use autoinjectors, available for 1ml or 2.25ml pre-filled syringes in a single device configuration. Ineos Styrolution says NAS ECO 21 is suited for applications demanding a strong, stiff, water-clear plastic resin with excellent thermal stability. The grade offers properties such as transparency, high surface quality, and low density. The company says the Carbon Footprint Reduction of this grade is 93%. John Palmer-Felgate, industrial designer and Founder of Eco-inject, says: “At Eco-inject, we focus on solutions that are both economic and ecofriendly. We are striving for sustainability and elegance while also reducing cost of goods. With Ineos Styrolution’s sustainable ECO materi- als, we can achieve just that. Using bio-based plastics dramatically reduces the carbon footprint of autoinjector devices, allowing them to meet increasingly stringent healthcare sustainability criteria. This will allow consumers to continue to benefit from using these self-administered devices in their own homes.”
Bio-derived grades Plastic tubing has a wide range of critical medical uses, such as for catheters and minimally invasive medical devices. Tubing, along with other components such as bags and connectors, also plays a crucial role in
sterile manufacturing of biopharma- ceuticals. Fluid-flow paths can be made with single-use components that are used for a single batch of product, which eliminates the need for cleaning (and the associated water and chemical use) between batches. These systems have been found to have a lower environmental burden than conventional, multi-use systems, but the industry is also looking at options for improving circularity and further reducing carbon footprint. Using bio-based plastics is one option. Avient’s latest addition to its
healthcare solutions are Versaflex HC BIO thermoplastic elastomers (TPEs). The initial grade, Versaflex HC BIO BT218, was developed as a more sustainable alternative for biopharma- ceutical tubing. The TPE is formulated with nearly 40% first-generation biomass content, resulting in a lower carbon footprint than traditional alternatives. The bio-derived grade offers greenhouse gas emissions at 2.35 kg CO2e/kg product, which Avient says is a nearly 25% percent lower cradle-to-gate Product Carbon Footprint (PCF) than Avient’s standard Versaflex HC BT218 grade. “Creating specialty materials that
reduce carbon emissions at the beginning of the product life cycle is one way we can support customers in fulfilling sustainability commitments and maintain critical performance demands,” says Matt Mitchell, Director, Global Marketing, Specialty Engi- neered Materials at Avient. “The bio-based launch has sparked conver- sations around sustainability in medical
