Nuremberg, Germany 12

Nuremberg, Germany 12 – 14.11.2008 Celebrities Zealand’s “Good Water” Raw Materials – Technologies – Logistics – Marketing 48. European Trade Fair for the Beverage Industry The bottle was developed with input from the Sir Peter Blake Trust. Good Water supports the Trust by donating a percentage from the sale of every bottle sold in order to help fund the Trust’s environmental education programmes for young Kiwis (that’s how the New Zealanders call themselves). “Our goal is to have raised million for the Trust by 2012. It forms a nice loop using an environmental initiative like Good Water to help fund teaching kids about the environment,” says Hall. Dubbed The Good Water Project, the objective of the company is to also recycle the bottles. Good Water currently recycles the bottles from its home and office delivery service launched earlier this year by sending them to a recycling plant in the North Island. “The aim is to help reduce the overwhelming amount of plastic bottles being sent to landfill each year in this country. Currently all plastic bottles put out for collection in New Zealand are bailed up and exported to Asia, with the rest going to landfill as they do not biodegrade or break down,” says Hall. He says that although more Kiwis are still needed to get behind The Good Water Project there has been a groundswell of interest with many Kiwis logging onto the company website to find out more. “What we have achieved as a company in such a short space of time is a testament to the innovation and drive behind the Good Water vision for sustainability, which is obviously shared by many Kiwis. As more and more people learn about what we are doing we find they are becoming emotionally connected to the project and are advocates in the marketplace. We’re touching people from all walks of life with the vision we have for this project.” www.goodwater.org.nz The best preparation for the coming beverage year Organizer NürnbergMesse GmbH Messezentrum 90471 Nürnberg Visitor service Tel +49 (0) 9 11.86 06-49 99 Fax +49 (0) 9 11.86 06-49 98 visitorservice@nuernbergmesse.de • Safely invested: 1,400 exhibitors present the latest technologies, raw materials, logistics and marketing ideas • Perfectly arranged: Innovations, experiences, contacts – here the industry shows the way ahead • Fully informed: New theme pavilions on IT in the beverage industry and production, purchasing and use of renewable energy Wanted?

For 2010 the forecast is for a demand of 260 million tonnes. The packaging industry requires about 25% of the plastic that is traded as granulate [1]. Given the constantly increasing material prices bioplastics offer a medium to long term alternative to those plastics obtained from fossil resources. Alongside the possibility of cutting down the need for petroleum-based products, bioplastics offer other advantages in terms of biodegradability and ecological balance, with the latter aspect being the subject of some heated discussion. Furthermore the socio-political structure implied in the use of renewable resources is also mentioned in this regard, with the increased use of renewable resources strengthening the role of the agricultural sector. In the food industry bioplastics are already widely used as film or blister packaging. Their use in bottles and caps is just beginning. Initial work By the end of the 20th century the German company Ki-Si-Co GmbH was already working on the manufacture of caps and closures made from alternative materials. The first trials were carried out using materials based on wood and lignin (fig. 1). One feature of these materials is that they are very hard, and so are not suitable for one-piece caps because they always need a liner. Their potential use is really limited to the field of rustic designs. A further problem with these plastics is that they are not at all easy to handle and process. Because of the, at times, very high fibre content they need wide gate diameters. The feed performance of the screw is also at times very difficult to control. Despite intensive efforts it was impossible to successfully process all of the various materials using existing tooling. The tools must be adapted to the specific properties of each individual bioplastic. 18 bioplastics MAGAZINE [05/08] Vol. 3
