Application News PHA to

Application News PHA to diagnose and combat tumours For the very first time, bioplastic can be used to diagnose and treat tumours thanks to the first patent registered by Bio-on (San Giorgio di Piano, Italy) in the nanomedical field, particularly in nanodiagnostics (nanoimaging). Bio-on researchers use nanotechnologies to create minerv BIOMEDS: these are revolutionary and innovative nanocapsules in PHAs bioplastic (polyhydroxyalkanoates) capable of simultaneously containing two contrast media: magnetic nanoparticles and gold nanocylinders. These two elements flag up diseased areas of the body, e.g. a tumour mass, using traditional Nuclear Magnetic Resonance and the more innovative Photoacoustic imaging. “Using PHA bioplastic is very advantageous,” explains Prof. Mauro Comes Franchini, Bio-on Chief Scientific Advisor, “because it is safe for the patient and has no side effects. As an industrial chemist, my main goal is to work with products that are safe for the environment and human health, especially when it comes to biomedical applications. Bio-on bioplastics fully meet these requirements and open up important, unexplored fields for nanotechnologies in medicine - a rapidly growing sector.” This technology has a diagnostic as well as a therapeutic function, given that drugs can be inserted into the nanocapsules, for chemotherapy for example. This will enable minerv BIOMEDS nanocapsules to be used in targeted and selective cancer therapies in the future. Combining Therapeutic with Diagnostics has led the two terms to be fused, thus creating Theranostics. “This versatility makes nanocapsules multifunctional,” explains Franchini, “and this dual system will allow clinical theranostic applications in oncology and in neurodegenerative disorders, enabling medical professionals to work safely on patients.” The sustainable and biodegradable PHAs bioplastics developed by Bio-on are made from renewable plant sources with no competition with food supply chains. The research conducted and the patent registered by Bio-on show that they can be used successfully in the nanomedical field precisely because they are biocompatible and safe for human health. The global market in contrast media alone is dominated by four multinational companies that generated an overall turnover of USD4.3 billion in 2015. According to the most recent estimates, this figure should rise to billion with 39.5 % growth over the next 5 years. “We are proud to contribute to such an important sector for human health,” says Bio-on Chairman Marco Astorri, “We will continue to do so by extending our direct presence even more in the biomedical and nanomedical sector.” MT www.bio-on.it New PLA cup recycling system Recently, a new recycling system for sustainable drinking cups was introduced at Noorderzon Festival in Groningen, The Netherlands (18-28 August 2016). For this project the disposable bioplastic (PLA) cups were recycled and made into drink tokens for the next edition of the Festival. During the festival, multiple companies such as Rotterdam based Bio Futura B.V. will join forces and gather approximately 500,000 bioplastic cups, which will be recycled. Visitors are asked for help and will be rewarded a drink token for every 50 cups they hand in. The cups will be transported to a Belgian factory, specialized in recycling. Here they will be shredded, washed and melted into granulate, ready to be made into drink tokens for the 2017 edition of the Noorderzon Festival. A great example of Reduce, Reuse and Recycle. The festival has been using bioplastic cups for many years now. These cups are made from biobased PLA. During the production a significantly lower amount of CO² is released in comparison to petroleum based plastics. After use the material can be industrially composted or transformed into biogas. However, whenever possible, recycling would be an even more sustainable option than composting. Through recycling, the raw material can be saved and this completely closes the loop. The festival offers a wide range of activities and performances. Next to this, the festival also pays attention to science and innovation. “It is thanks to these constant innovations that we are able to get few steps closer to a biobased economy,” said Wouter Moekotte, owner and founder of Bio Futura.

Last minute K-Show News Application News Buss Laboratory Kneader MX 30-22 High-tech bio-PA fibres At K’2016 Evonik, the specialty chemical company is presenting women’s fashions! The fascinating part: The elegant garments are made 100 % of innovative biopolyamide fibres based on VESTAMID ® Terra. The high-tech textile fibres have a lot to offer: maximum wearing comfort and unexcelled performance. They are extremely light, flexible, and breathable. Processed into high-quality fabrics, they have an odor-reducing effect thanks to their lasting natural bacteriostatic characteristics. In addition, they dry quickly and require no ironing. Because of their uniqueness, the innovative high-performance fibres can be processed in all textile applications, including an Italian designer fabric for evening gowns, functional sporting togs, and durable upholstery materials. The fibres are produced from Vestamid Terra, a biopolyamide that is obtained 100 % from the seeds of the castor bean plant. In addition to the environmental advantage, it is above all the sustainability approach of Vestamid Terra that is so convincing. Since castor bean plants can also withstand long periods of drought, they are cultivated in dry areas which are not suitable for any other form of agriculture. The biopolymer from Evonik’s Resource Efficiency Segment therefore has no adverse effect on the human food chain. Unlike various other biopolymers that are based on natural products grown on cropland. The product development process profited from Evonik’s technical expertise in the area of highperformance plastics as well as the fibre-processing experience of Fulgar, an Italian fibre manufacturer, which markets the biopolyamide fibres under the brand name EVO ® . With Vestamid Terra, Evonik offers three variants of biopolyamides, PA 610, PA 1010, and PA 1012, which differ in their profile of properties and close gaps in the previously available range of properties of polyamides. They are long-lasting, durable, and meet the requirements of demanding applications, for example in the automotive, sports, and textile industries. Typical applications of Vestamid Terra products are injection molding, fibres, powders, extrusion, and films.MT www.vestamid-terra.com 6B28 Buss Kneader Technology Leading Compounding Technology for heat and shear sensitive plastics For more than 60 years Buss Kneader technology has been the benchmark for continuous preparation of heat and shear sensitive compounds – a respectable track record that predestines this technology for processing biopolymers such as PLA and PHA. > Uniform and controlled shear mixing > Extremely low temperature profile > Precise temperature control > High filler loadings Hall 16 Stand 16/A59 bioplastics MAGAZINE [05/16] Vol. 11 27
