9. There are six options to consider when deciding how to minimise waste production at the end of the life cycle stage. The six Rs are as follows : • R e du ce • R e think • R e u s e • R efuse • R e cycle • R epair The six Rs should be considered by the designer, the manufacturer and the customer. From a design perspective, to minimise waste and reduce the environmental impact, the designer can : • Make products easy to disassemble for recycling • Limit the use of toxic materials • Use biodegradable materials where possible • Arrange collection of materials at end of life stage Disposal

10. The 6 Rs - Reduce R e d u c e t he a m ou n t of m a t erials n e ed e d t o p a ck a g e a p r o du c t Cost savings and improved profit Reduced environmental costs Under the UK Producer Responsibly Organisations (Packaging Waste) Regulations (1997), manufacturers are obliged to reduce packaging by : • Considering the materials and design • Examining the ways of eliminating packaging • Optimise packaging - match packaging to level of protection needed

11. The 6 Rs - Reuse • Companies have adopted returnable or refillable containers for some products. An example is the door step delivery of milk. However, whilst refillables appear to offer environmental benefits they can often require greater use of resources so they can withstand the rigours of reuse. • If reuse is viable then the costs of collection, washing and refilling should be less than producing a new container.

13. The 6 Rs - Rethink Rethink R ethinking the way a product is manufactured and redesigned can have a positive impact on the amount and type of materials used.

14. The 6 Rs - Refuse Refusing R efusing to use certain types of materials with the design and manufacturing process and using a more sustainable material instead .

15. The 6 Rs - Repair Repair W hen a product is broken, consider whether it can it be repaired rather than being discarded. Repair can help save on cost and minimise the use of non-renewable materials and energy used in the manufacturing process.
