stica per automobili. Non c’è praticamente nessuna casa automobilistica che rinunci completamente alle bioplastiche o che non ne progetti un impiego ancora più intenso nei propri veicoli. Per chi desideri raccogliere maggiori informazioni su potenziale, opportunità, nuovi sviluppi e applicazioni innovative in merito alle bioplastiche, la K 2013 offre moltissime occasioni agli stand degli espositori. La principale fiera mondiale del settore per le materie plastiche e la gomma si terrà a Düsseldorf dal 16 al 23 ottobre di quest’anno. Inoltre dal 17 al 19 ottobre, rispettivamente stati assieme ai rifiuti organici.

at several 100,000 tonnes accounted for the lion’s share of total global capacity for bioplastics in 2009. Since 2010, the growth rates for biodegradable plastics have been far outstripped by those for bio-based plastics. According to association forecasts and despite constant growth, they will account for only about a seventh of overall bioplastics output by 2016. The far larger share of bioplastics will then be bio-based but not biodegradable. Rising standards – bioplastics are no exception For their growing technical applications, plastics have to meet increasingly high standards. And bioplastics are no exception. As far as reproducibility is concerned, they still have some catching-up to do, and in terms of barrier properties, durability and compatibility with other biopolymers and

additives, there is still plenty of room for improvement. Bioplastics and their applications today Biodegradable plastics are usually employed in applications where degradability proves to be particularly useful. This applies, for example, in agriculture to mulch films and plant pots that do not have to be collected and transported elsewhere after use, but metabolise on the spot in the soil to form biomass. In private households, degradable kitchen waste bags have conquered a market and can be composted together with their contents. Bio-based plastics are now also found in consumer electronics and automotive applications. For its Sai hybrid car only available in Japan, Toyota, for instance, has developed interior furnishings and equipment made of 80 per cent renewable raw materials, as of

model year 2011. This has been made possible by the use of bio-PET, a plastic derived from sugar cane. Nonetheless, PLA and polyurethane (PU) foam based on soya are also found today in a vast diversity of automotive components. Practically all car manufacturers make use of bioplastics in their vehicles and are working towards increasing their use. If you want to find out about the prospects for and potential of bioplastics along with the latest developments and innovative applications, you will have plenty of opportunities to do so at the exhibitors’ stands at K 2013. The world’s most important trade fair for the plastics and rubber industry is taking place this year in Düsseldorf from 16 to 23 October. In addition, Bioplastics Business Breakfasts, brief seminars on selected industry topics, will be taking place from 17 to 19 October, daily from 8 to 12 h.
