I encourage you to read these case studies and the team at Plastics NZ would appreciate any feedback. In this publication Plastics New Zealand has profiled six iconic Kiwi plastic products. These are the first in a series that will look at plastic products that have made a difference in the NZ environment and to the lives of New Zealanders and many people overseas. These case studies highlight the innovation and Kiwi Dennise Chapman, ingenuity that went into their design and manufacture. An Chair Environmental Committee, important part of these profiles is to identify improvements Plastics New Zealand made to the environmental footprint in the different phases of the product’s lifecycle. Introduction We have profiled six iconic Kiwi plastic products across the The iconic Kiwi plastic products are: plastics industry.

During the fourth year (2006-2007) of the successful Plastics Best Practice Programme we have worked with plastics companies and encouraged them to use the tools developed in the programme to date. We would like to Ket Bradshaw congratulate all our Plastics Best Practice companies on Environmental Manager their achievements to date. Plastics New Zealand In 2006 we published the Plastics NZ Design for the Environment Guidelines about developing products in a way that minimises their environmental impact; http://www. plastics.org.nz/_attachments/docs/bpp-dfe-final-4.pdf These guidelines profile some of their exciting design Simon Wilkinson projects, clearly demonstrating that good design improves Best Practice Facilitator performance and is good news for business and the Plastics New Zealand environment. We profiled our Best Practice Programme Acknowledgements Plastics New Zealand would like to thank the many people who have helped with these case studies and the Best Practice Programme participants who have generously given their time and resources.

It demonstrates Kiwi technology used to enhance the quality and safety of our innovation in flexible packaging, an area where New exported products. The cheese pouch is exported from Zealand has excelled over the last 30 years. Its significance Hamilton to cheese factories throughout the world. Material and process efficiency Lightweighting The multi-layered plastic protects the cheese from Since 1998 there has been a gradual degrading and allows the maturing process to take reduction in the thickness of the plastic place for up to 18 months. Many environmental pouches from 120 to 90 gains have been achieved through product microns. This represents development and improvements a 25% reduction in the such as automation of the material used in the filling of the pouches at millions of these bags the cheese factory. produced each year. Under the manual filling system, bag lengths were 690 mm. Now they are able to be manufactured to 670 mm – a reduction of 5% that represents a material saving of hundreds of kilometres of plastic every year. Distribution improvements Cheese pouches are now distributed to Recycling cheese factories in a vacuum bag rather than cardboard boxes. This has significantly reduced the The Sealed Air factory that makes volume of the product for distribution. The new system means the cheese pouches has reduced 160% more bags can be fitted onto a pallet within New Zealand and 240% manufacturing waste going to more bags on an export pallet. These improvements have reduced truck trips landfill by 80%. Since 2001 in New Zealand by 40% and the number of 20-ft containers used for export recycling has steadily increased has been reduced by 60%. Carbon dioxide (CO2) emissions have also been from 45% to more than 80% now saved through this reduction in transportation and the company no longer
