Application AutomotiveNews Peeling milk with P3HB In October 2018, the Czech companies NAFIGATE Cosmetics and NAFIGATE Corporation launched a new product - Coconut shower peeling milk, in which microbeads are replaced with Hydal P3HB. The whole new cosmetics eco-design concept received the name Dedicated to You and Nature in order to express its biodegradability and biocompatibility. Hence, coconut shower peeling milk represents a circular revolution in the cosmetics industry. It is fully biodegradable, waste-free and harmless to nature. Microplastics are solid plastic beads of less than five millimetres. In cosmetics, they are used as peeling particles in the form of polyethylene microbeads of less than one millimetre in their largest dimension that peel off dead skin cells. Once microbeads are washed off from skin, they get into water, where they do not biodegrade. Microbeads can cause plastic water pollution and be harmful to aquatic life because wastewater treatment plants cannot capture such small particles. According to various research studies including the results of the Institute of Hydrodynamics of the Czech Academy of Sciences, drinking water also contains microplastics. P3HB biopolymer is processed by the unique Czech biotechnology HYDAL, which as the first in the world on industrial scale uses 100 % waste in the form of waste cooking oil (WCO). Hydal P3HB is added in the shower peeling milk in the form of white particles, replacing the abrasive function of microbeads. Unlike other abrasive materials utilized in cosmetics, biopolymer’s properties, such as sharpness or size, may be modified. In addition, P3HB as a pure chemical substance allows meeting the highest hygienist cosmetics standards. In contrast to other substances, it dissolves in water completely. According to the company’s tests, biopolymer biodegrades in wastewater treatment plant within several days, in the open environment up to several dozen days. It does not harm nature and provides a solution to one of the most serious challenges in the cosmetics industry. MT | New bio shoe line Leading global barefoot footwear company VIVOBAREFOOT, headquartered in London, UK, recently announced the launch of its new Bio shoe range featuring Primus Lite Bio, plant-based performance sneakers. Designed with outdoor performance in mind, the Bio range is made from a combination of three innovative bio-based materials that reduce reliance on petrochemicals and ultimately create more efficient and sustainable products. Each shoe in Vivobarefoot’s new line is nearly 50 % plant-based, making it Vivobarefoot’s latest stride in their quest to use 90 % sustainable materials across its entire product range by 2020. The materials used in new Primus Lite Bio range are produced by DuPont Tate & Lyle Bio Products, a joint venture between DuPont, a global science innovator, and Tate & Lyle, a worldleading renewable food and industrial ingredients company. Through the use of these renewable, highperformance materials, Vivobarefoot is able to make a significant impact on the planet. Every 50,000 pairs of shoes produced using these materials, equates to saving greenhouse gas emissions from 247,948 miles driven by an average passenger vehicle or reducing CO 2 emissions from 11,286 gallons of gasoline consumed. “We are trying to make a significant impact through working with game changing brands like Vivobarefoot who are committed to producing products with fantastic technical performance and improved sustainability profiles,” stated Laurie Kronenberg, global marketing director at DuPont Tate & Lyle Bio Products. “In working with Vivobarefoot on optimizing their plant-based content throughout the shoe using various Sorona PTT fiber and Susterra bio-PDObased solutions it allowed us to model the environmental reductions in terms of greenhouse gas emissions and nonrenewable energy on a raw material basis. Now that is impactful.” Seventh-generation shoemakers Galahad and Asher Clark are firm believers that barefoot shoe-making is sustainable shoe making. The company has already pioneered shoes made of repurposed algae (Ultra 3 BLOOM) with each pair recirculating 215 litres of fresh water back into the natural habitats, and an Eco range made of 50 % recycled plastic. In 2017, Vivobarefoot diverted over 2 million plastic bottles from landfills into barefoot shoes. “Sustainability is at the core of Vivobarefoot’s mission and we believe that the perfect shoe has minimal interference with natural movement and minimal impact on the environment,” said Asher Clark, design director at Vivobarefoot. “The new Primus Bio line champions the future of sustainable materials and the new opportunities they bring to the footwear industry.” The Vivobarefoot Bio range will include the hero performance shoes Magna Trail Bio, Primus Trail Bio, Primus Lite Bio and Ultra Bio shoes. The Primus Lite Bio shoes for example will be available at www.vivobarefoot. com/us starting June 2019 and priced from 0 to 0. MT 36 bioplastics MAGAZINE [06/18] Vol. 13

Application News Clipper tea bags renewably-sourced Public outcry about and subsequent resistance to tea bags made with polypropylene has compelled brand owners to take action. The latest to do so is Clipper Teas, the tea brand owned by natural and organic food company Wessanen, Amsterdam, The Netherlands. The company announced in April of this year that it had committed to use only fully biodegradable tea bags by summer 2018. It was a little later than that, but on October 20, the company said it moved all production to ‘plastic-free, unbleached and non GM (genetically modified) tea bags’, adding: “And we won’t be going back!” There will be a transition period of up to a few months while retailers sell through current stock, said the company as “we don’t believe in waste”. According to Clipper, the polypropylene in the tea bag paper originally served to heat seal the two layers of the unbleached tea bag paper together. The company has now developed an alternative tea bag paper, made from natural, plant based materials – a blend of abaca (a species of banana), plant cellulose fibres and a PLA derived from non-GM plant material that helps hold the paper together. In the past, while aware of the availability of this plant-based option, Clipper had never used or considered using PLA, as the corn used as feedstock in the PLA made by one major manufacturer could be from GM sources. Since the official announcement, other producers have also entered the market, offering PLA guaranteed to be from a non-GM source and enabling Clipper to make the switch to a 100% renewably-sourced tea bag paper. To let consumers know about the change, an on-pack flash will be rolling out on specific products from January 2019.
