Application News

Application News Compostable Synthetic Leather Green Dot (Cottonwood Falls, Kansas, USA) has developed a compostable synthetic leather made with the company’s Terratek ® Flex bioplastic. The new synthetic leather combines the look and feel of high quality leather with a lighter environmental footprint compared to traditional leather tanning or synthetic leather manufacturing. Green Dot’s new synthetic leather is made without the use of solvents or glues. It is free from phthalates, Bisphenol A and other toxins often found in the soft plastics used for synthetic leathers. Because it’s made with Green Dot’s compostable bioplastic, the material can be returned to nature if placed in a composting environment when its useful life is over. Terratek Flex GDH-B1 has been independently tested and verified to meet European (EN 13432) and North American (ASTM D6400) standards for compostability in an industrial composting facility and has been found to biodegrade in a home composting environment as well. Green Dot has completed initial trials with manufacturing partners in the United States. The new synthetic leather can be made in a wide range of colors, textures and thicknesses with a variety of naturally biodegradable backings. The starch-based bioplastic provides an exquisite soft touch and better breathability compared to other synthetic leathers. It is also ideal for printing and may be easily scented to provide further product differentiation. Green-minded glueing With the UHU stic ReNATURE, paper glueing is getting sustainable. The popular glue stick offers consumers a new and more environmentally friendly alternative to existing products – in an attractive design. The new UHU stic ReNATURE overcomes all challenges in the glueing of paper, carton, cardboard and styrofoam in the accustomed quality, showing that even a small product can make a substantial contribution to environmental protection and the saving of fossil resources. 58% of the UHU stic ReNATURE’s container consists of renewable raw materials, namely sugar cane based bio-PE. Some other parts of the container still have to be made from conventional plastics, such as e.g. the practical screw cap, to ensure a tight seal. The cap prevents the glue from drying out and makes it last longer. As well as being fully recyclable, the new UHU stic ReNATURE is solvent-free and 70% of the glue formula is nature-based. Another ecological as well as economic advantage is that the UHU stic ReNATURE is far more efficient in its application and more economical than comparable products. With the medium-sized UHU stic ReNATURE, users can glue approximately 200 sheets of A4 paper more than would be possible with its main competitor. “At UHU, we attach a great deal of importance to sustainable business,” says Frank Walther, Senior Product Manager Corporate Marketing at UHU. “We want to reduce the environmental impact of our products as much as possible and we are continuously looking for alternatives for example to crude-oil-based products. But the quality of our products is just as important as their environmental compatibility and the safety of their usage and disposal by consumers.” The UHU stic ReNATURE recently received the Österreichisches Umweltzeichen für Produkte (the official Austrian environmental label for products), which is a hallmark of high environmental standards, quality and product safety. And it has been named Product of the Year 2014 in the environmental protection category by the PBS, the German Industrial Association for Paper, Office Supplies and Stationery. The new UHU stic ReNATURE particularly impressed the jury with its pioneering use of renewable raw materials, which helps protect natural resources and the environment.

Application News Compostable ice cream sticks Cardia Bioplastics Limited (Mulgrove, Victoria, Australia) is pleased to announce the use of Cardia Bioplastics compostable resin technology for the development of So Delicious ® Dairy Free’s innovative compostable ice cream sticks. So Delicious Dairy Free purchased first commercial quantity of Cardia Compostable resin for ice cream stick market launch. The initial market launch media buzz has demonstrated that the new compostable sticks are extremely popular with consumers for both taste and environmental reasons. So Delicious Dairy Free took the innovative steps to replace traditional wooden sticks by designing an entirely new solution – plant-based, lickable, compostable sticks. Although sustainability plays a major role in So Delicious Dairy Free‘s proposition, the change to Cardia Compostable resin for the ice cream stick application was driven from consumer feedback, indicating they are averse to the feel and aftertaste of traditional wooden sticks in single serve ice creams. The new stick material is fully compostable and meets the requirements of the ASTM D6400 Standard for composting in municipal or industrial facilities. In addition, the sticks have undergone a series of rigorous tests including two pilot scale compostability tests and one commercial composting test, with results showing that the new sticks compost much faster than their wooden counterparts. Dr Frank Glatz, Cardia Bioplastics Managing Director said, “The Cardia technical team worked with So Delicious Dairy Free, to ensure that the resin technology used for the ice cream sticks met consumer needs and compostability standards required for food application. We are very pleased with the result, and are certain that consumer feedback and demand will motivate more manufactures to look to a compostable ice cream stick solution.” Richard Tegoni Chairman Cardia Bioplastics said, “The So Delicious Dairy Free market launch of Cardia Compostable ice cream sticks in the food and consumable markets, replacing traditional materials further demonstrates the vast possibilities and applications of our resins. Not only are Cardia Compostable resins food safe, have a lower carbon footprint and are compostable compliant to international standards, but as consumer feedback demonstrates they are preferred for certain applications.” MT in Raw Materials, Machinery & Products Free of Charge from the Industrial Sector and the Plastics Markets for Plastics. for Plastics & Additives, Machinery & Equipment, Subcontractors and Services. for Specialists and Executive Staff in the Plastics Industry bioplastics MAGAZINE [02/14] Vol. 9 43
