Application News

Application News Biobased lids and scoops Nestlé (Vevey, Switzerland) recently announced that it will introduce biobased lids and scoops made from sugar cane and its by-product for a range of its nutrition products for infants and children. The main advantage of these biobased plastics is that they are made from a renewable plant material that can be continually replenished and that absorbs carbon dioxide from the atmosphere. In addition, this packaging helps Nestlé reduce its use of fossil-based plastics. Nestlé Nutrition’s Nan infant formula packed in the new packaging materials was introduced in Hong Kong in 2020 and will be available in other markets globally from 2021, including for other brands such as Beba and Guigoz. Wyeth Nutrition is launching the new biobased packaging for its brands Sma, Little Steps, S-26, and Illuma. Nestlé Health Science is also introducing the new packaging material for its Althéra, Alfaré, Alfamino, Modulen, and Peptamen Junior brands, which are part of its global range of paediatric food for special medical purposes. Greg Behar, CEO of Nestlé Health Science, said, “It is our responsibility to our customers and to our planet to innovate on packaging materials that contribute to a more sustainable future. We are pleased that Nestlé Health Science’s paediatric range is our first product group to include the new biobased lids and scoops: new solutions for a new generation.” The lids and scoops are made from 66 % and 95 % sugar cane respectively. They are certified as plantbased packaging and are recyclable in countries that have recycling facilities for polyethylene (PE). They have the same properties and functionalities as conventional plastic ones, without compromising the high level of hygiene and freshness required. The biobased lids and scoops complement the tin can which is metal-based and is the most recycled material in the world. This innovation is one of the many solutions Nestlé is working on to address the issue of packaging waste. Ryan Carvalho, Head of R&D and Chief Medical Officer for Nestlé Nutrition said, “The development of innovative sustainable packaging solutions plays an important role in our journey to net-zero. Biobased packaging from sugar cane is an excellent example of how we can make good use of plant-based raw materials that are renewable to develop better alternatives to traditional plastic while ensuring that our products maintain a high level of safety and quality.” Nestlé is a founding member of the Bioplastics Feedstock Alliance that aims to encourage the production of bioplastics feedstocks in an environmentally responsible, socially beneficial, and economically viable manner. AT Calendered PLA sheets A high number of inquiries about calendered sheets made of renewable raw materials has encouraged the German company Gehr from Mannheim to develop a new product: ECO-GEHR PLA-HI ® . Effective immediately Gehr offers these sheets made of cornstarch based PLA combined with additives. They are produced — as all Gehr products — CO 2 neutral according GHG Protocol Scope 1+2. The sheets stand out for their high impact strength and are therefore suitable for use in demanding applications. Mechanical processing of the sheets is easily possible. Postprocessing can be applied without any problems such as: • thermoforming • sawing • printing • drilling • glueing • punching The following sheets are available from stock: thickness 2, 3, and 4 mm (width: 1000 mm, length: 2000 mm). Currently only available in natural/ translucent colour, the sheets can also be produced in different colors. MT 34 bioplastics MAGAZINE [02/21] Vol. 16

More bio in surfing Researchers at the Fraunhofer WKI, Braunschweig, Germany, are developing the stand-up paddleboard ecoSUP with a lightweight sandwich element made from renewable raw materials. Lightweight construction materials are environmentally friendly, as less energy and fewer resources are required for transport and production. Conventional lightweight-construction materials are based on fossil and other finite resources such as metals and minerals. “We selected a stand-up paddleboard as the demonstration object for our lightweight-construction material, as it has to meet high requirements with regard to mechanical strength in combination with resistance to moisture, saltwater, and UV radiation. In the future, our new biocomposite material could be utilized not only in other watersports equipment but also in the construction of buildings, cars, ships, and trains,” explained Christoph Pöhler, Project Manager at the Fraunhofer WKI. Currently, watersports equipment, such as surfboards, is produced using petroleum-based materials such as epoxy resin, polyester resin, polyurethane, and expanded or extruded polystyrene in combination with glass and carbon-fibre fabrics. The market for glass- and carbon-fibre-reinforced plastics is also growing continuously in other economic sectors. This offers a high savings potential for finite resources. Application News “For the core of the new bio lightweight-construction material, we use recycled balsa wood and modify it accordingly. Balsa wood is used in large quantities in the rotor blades of wind turbines. At the end of the life cycle of the rotor blades, it accumulates as waste and is then burnt. We now want to give this balsa wood a longer useful life,” Pöhler explained. The researchers are also developing an outer shell made from natural-fibrereinforced bioplastics on the basis of itaconic acid. They are hereby concentrating on the application of flax fibres, as these have advantageous mechanical properties and are cultivated in Europe.

The reusable cups are manufactured from biobased (up to 75 %), heat tolerant (with temperature resistance 83–96 °C, HDT b), and compostable (EN-13432/Industrial compost) ArcBiox TM MFA-series containing inorganic mineral fillers. The injection moulded design items are part of Cormaf’s From Nature to Nature series, which is readily available for consumers at or by contacting Cormaf sales directly. The cups are light to carry and designed for informal occasions such as outdoor picnics. Riccardo Chiaveri, the owner of Cormaf explains: “The main driver for Cormaf is to combine sustainability and aesthetics. The high-performance ArcBiox materials met our needs in terms of sustainability and usability of our products. For example, high heat-resistance is needed to allow hot beverages and dishwasher durability.” Ari Rosling, the R&D director at Arctic Biomaterials adds: “The cosmetics and food sectors are definitely one target market for our recently launched MFA-series. It was delightful to see what glamorous items Cormaf was able to design and produce using it. And I have heard they are delivering other innovative ideas in the near future as well.” According to Arctic biomaterials the ArcBiox MFA-series can compete with many oilbased plastics, such as PE, PP, PS, and glass-reinforced PA, PP, PC, and PBT, and offers a viable alternative to ABS, PP, and PS.
