![Page 4: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/4.jpg)
What is ecodesign?
‘Design for Environment’ or ecodesign is about developing products in a way that reduces their
environmental impact
The aim is to design products that are functional, desirable, cost-effective, and have no harmful side
effects on the environment
![Page 5: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/5.jpg)
Life cycle thinking
– The key to ecodesign is understanding the environmental impacts of your product throughout its life cycle, i.e. from raw materials extraction or harvesting, through to how the product is disposed of or recycled at the end of its life
![Page 6: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/6.jpg)
Life cycle thinking (‘cradle to cradle’)
Raw Materials material processing

Why focus on design?
Most of the environmental impacts of a product are “locked in” at the design stage, when materials and processes are specified. This determines:
- whether extraction of raw materials will contribute to land degradation or biodiversity loss, etc
- whether toxic or hazardous wastes will be produced in the manufacturing process
- whether the product will be easy or hard to recycle…
- etc
![Page 8: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/8.jpg)
Ecodesign could involve….
– Design of a new ‘greener’ product– Minor changes to an existing product, e.g. switching from
100% virgin polymer to 25% recycled– Redesign of your transport packaging system to improved
efficiency (e.g. secondary / transport packaging)– Ecodesign guidelines for suppliers– Taking waste back from customers for to reprocess back
into their product– New labelling to encourage responsible disposal or recycling
![Page 9: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/9.jpg)
Why ecodesign is important
1. Business reasons
2. Ecological reasons
3. Social reasons
![Page 10: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/10.jpg)
1. Ecodesign and business
– Ecodesign can add value to business by:– Reducing costs (materials, energy, waste, transport)– Meeting product stewardship regulations here and
overseas – Improving corporate reputation (impacts on share price,
access to finance)– Provide a competitive edge in environmentally aware
market segments– Improving relationships with suppliers and customers– Becoming a new source of innovation
![Page 11: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/11.jpg)
Product stewardship regulations
– Take-back requirements / producer responsibility– Recycling / recycled content targets– Bans on toxic or hazardous substances– Container Deposit Legislation (CDL)– Voluntary programs supported by regulation
– The preferred model in Australia and NZ
![Page 12: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/12.jpg)
Competition
– “Our products are designed with the environment in mind. The latest Canon digital cameras are totally free of hazardous materials. Our new Bubble Jet printer uses 68% less energy than the previous model….”(Canon advertisement, The Age, 21/8/04)
![Page 13: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/13.jpg)
2. Ecodesign and the environment
– Humans are embedded in and entirely dependent on, the processes of nature– BUT we causing irreversible harm to the natural
environment– Environmental damage is caused by:
– Growing population– Technological advances– Increasing affluence and consumption
– Manufacturers have a critical role to play in reducing impacts
![Page 14: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/14.jpg)

3. Ecodesign and society
– Consumers care about the environment (although back of mind issue for most)
– Environmental pressure groups can have a major impact on business– Confrontational campaigning (e.g. Greenpeace,
Boomerang Alliance)– Advocacy and partnerships (e.g. Plant Ark, Clean Up
Australia)
![Page 16: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/16.jpg)

Discussion
– Has your company already implemented any ecodesign strategies?– Why or why not?
– Are there any external pressures on your business, e.g. from customers, government or NGOs?
![Page 19: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/19.jpg)
Ecodesign principles and strategies
1. Efficient design
2. Cyclic design
3. Safe and clean design
4. Communication design
![Page 20: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/20.jpg)
1. Efficient design
– Keep material and resource inputs to a minimum– Do more with less– Strategies:
1. Eliminate unnecessary components
2. Use less material in the product (e.g. downguage)
3. Maximise efficiency of operation (minimise use of energy, water, consumables)
4. Design for durability
![Page 21: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/21.jpg)
2. Cyclic design
– Design to enable materials to be continuously cycled through natural or industrial systems
– Eliminate waste
Natural (biological) cycles Industrial (technical) cycles
![Page 22: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/22.jpg)
2. Cyclic design (cont)
– Strategies for natural cycles1. Use renewable energy2. Specify materials which are renewable and sustainably harvested3. Specify biodegradable materials4. Select the right biodegradable material for the disposal environment5. Design the product so that it can actually biodegrade
– Strategies for technical cycles1. Specify materials which are technically recyclable and which have
an existing collection/recycling system2. Design for disassembly and recycling3. Use recycled materials4. Establish product stewardship programs (take-back)
![Page 23: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/23.jpg)
3. Safe and clean design
– Avoid toxic or hazardous substances and processes– Protect human health– Strategies:
1. Eliminate processes which generate toxic or hazardous wastes in production
2. Replace potentially toxic substances (heavy metals in inks and pigments, flame retardants, plasticizers etc)
![Page 24: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/24.jpg)
Communication design
– Encourage responsible consumer behaviour– Ensure product and packaging related communication is
informative and accurate– Strategies:
1. Label plastic components (PIC or international codes)
2. Use energy and water labels
3. Provide information on recyclability / appropriate disposal
4. Provide information on other environmental attributes

Selecting your ecodesign project
1. Select a product for ecodesign2. Map out the product life cycle – product flows and all of the inputs
and outputs along the life cycle3. Identify any internal or external stakeholders (e.g. customers,
government regulators) who are driving change4. Identify environmental ‘hot spots’ – i.e. where are the greatest
impacts?5. Identify ways that you can influence environmental impacts
through ecodesign 6. Select ecodesign objectives7. Select ecodesign strategies8. Take steps to integrate ecodesign in your business
![Page 49: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/49.jpg)
1. Selecting a product for ecodesign
Possible criteria:1. Do any of your products have significant environmental impacts?2. Are any of your products non-compliant with local and international
regulations?3. Are you under pressure from regulators or NGOs to change any of
our products?4. Are any of your products / markets at risk from future regulations or
NGO campaigns?5. Are you likely to increase sales of one of your products by appealing
to environmentally aware consumers?6. What are your competitors doing - are you going to lose market
share for one of your products if you do nothing?

3. Identify external pressures
– Customers, e.g. supplier guidelines, questionnaires– Government, e.g. voluntary programs, regulations (now and
in the future)– Environment groups, e.g. campaigns against your product– Consumers, e.g. interest in greener products
![Page 52: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/52.jpg)
4. Identify environmental ‘hot spots’
– These are key issues that will be addressed in the design process
– Based on your review of life cycle impacts AND stakeholder concerns
![Page 53: Ecodesign and the plastics industry Helen Lewis Plastics New Zealand Workshops Christchurch and Auckland 29-30 August 2005](https://reader034.vdocuments.mx/reader034/viewer/2022051516/56649e185503460f94b03be6/html5/thumbnails/53.jpg)
5. Identify ecodesign objectives
– Translate ‘hot spots’ into design objectives, e.g.– design for recyclability– reduce product waste / damage– reduce secondary / tertiary packaging– improve efficiency of transport logistics
