K‘2010 Preview Roll-Bag Solution for Bio-Bags Next Generation Recycling Machines NGR: An effective new technology for recycling bioplastics has been successfully developed by NGR (Next Generation Recyclingmaschinen) with its headquarters in Feldkirchen/ Donau, Austria. The specialists have long believed that plastics made from biomaterials cannot be recycled; NGR shows otherwise at K’2010. Roll-o-Matic, Denmark, has developed a new Delta converting line, the DELTAmax, which has longer sealing sections than the conventional Delta. In this way it is possible to reach the optimum combination of long sealing time and high sealing pressure at zero-tension, as required for high capacity, top quality converting of the medium/large size star sealed bio-bags. The DELTAmax can in this way reduce production cost and provide producers of bio-bags with new business opportunities. Valuable raw material... NGR has set its sights from the outset on ‘one-step technology’, in which plastics going through the recycling process are not subjected to high temperatures. And it is above all for the recycling of valuable bioplastics that this factor is now of enormous significance. This is because so-called natural plastics made from renewable growing resources are three to four times as expensive to produce as those based on petroleum. Moreover the typical NGR ‘one-step technology’ also offers high energy efficiency that is seen in operation via low electricity costs. ...feeding back into the production cycle. NGR regranulating technology for biological plastics is now to be demonstrated to a specialist public… 9D05 “With the right converting equipment, we expect that the market for medium and large size star-sealed bio-bags will expand rapidly, and we are pleased to offer our customers the possibility to open up new business opportunities,” comments Mr. Birger Sørensen, Managing Director at Rollo-Matic, Denmark. The DELTAmax with the star sealed T-shirt capabilities can be seen in operation at Roll-o-Matic’s stand. 03C54 GRAN recycling unit from NGR. 9D05 Biodegradable Polyester Resin Zhejiang Hangzhou Xinfu Pharmaceutical Co., Ltd: BiocosafeTM is the trade name of a biodegradable polyster resin manufactured by Zhejiang Hangzhou Xinfu Pharmaceutical Co., Ltd (in short XINFU). Besides being a global leading manufacturer of Vitamin B5 XINFU specialises in the fields of biochemicals, fine chemicals and Eco-materials. Biocosafe is a kind of biodegradable macromolecular polymer synthesised from diacid and diols through a direct process of condensation polymerization catalyzed with a highly effective non-toxic catalyzer that has been developed by XINFU. Biocosafe has already obtained EN13432 and ASTM D6400 certification. Three different grades are available for various applications: Biocosafe 2003 is a high shear strength and impact grade, suitable for film and bag applications. The 1803 grade offers HDT above 60°C and an elongation at break of over 600%. Suitable for tube, and straw applications. And finally Biocosafe 1903 with an HDT above 85°C and high impact strength. This grade is suitable for injection and extrusion 07.1E01-2 36 bioplastics MAGAZINE [05/10] Vol. 5

K‘2010 Preview A New Commercial Bioplastic Material with Broad Performance Capabilities Telles: Mirel bioplastics have made major strides forward this year. The Clinton, Iowa, USA production facility is now in operation. Mirel is available in a series of resin grades, including injection molding, thermoforming, film (cast and blown), and sheet extrusion. Mirel is ideal for a wide variety of applications, including single-use disposables; food service and packaging; compost, yard waste, and retail bags; agriculture mulch films; horticulture and marine products; and many consumer items. It is durable in use, shelfstable, heat-resistant up to 120°C, moisture-resistant, tough, and tearresistant. Mirel enables alternative waste management options including anaerobic digestion, home composting, industrial composting, soil and marine environments. Mirel offers biobased and biodegradable solutions that can help to reduce the amount of waste sent to landfills. 05D10-6A 08bA30 Bioplastics Services Natureplast specializes in supporting plastics converters or outsourcers who want to develop and integrate products or packaging in bioplastic. Their expertise is based on three complementary and inseparable activities to develop a successful product : • Natureplast has privileged access to all raw materials and additive bioplastics all over the world. They are even able to recommend specifications on the material best suited to the customer’s needs. • If none of the biopolymers on the market today correspond to the client’s expectations, Natureplast’s structure and network can set customized grades of material in order to meet product and process constraints. • Natureplast has also developed audit services, consulting and training to accompany you on your whole project. Beginning in 2011, Natureplast is proud to announce the opening of a laboratory completely dedicated to bioplastic research and development (compounding, injection moulding and characterisation). New grades of bioplastic will be developed to respond to industrial needs. New BioFoam Pallet Besides their standard EPS and EPP materials Synbra will be showcasing several items produced with their newly developed BioFoam ® material. This material is an expanded PLA, 100% biobased and biodegradable, and is C2C certified. BioFoam has comparable properties with EPS and within certain limits all EPS parts could also be made with this new material. Processing is done on traditional EPS equipment, however as a blowing agent CO 2 is used, which makes the processing a carbon neutral operation. At its end-of-life BioFoam can be disposed of in all the traditional ways, but PLA has some additional disposal options, namely industrial composting, anaerobic digestion and feedstock recycling.
