  1. Yr 11 Graphics Practice test with revision time given Friday 17th Sep Sustanability

  2. Topics to revise • What are the 6 R’s • Recycling – what materials can be recycled, what are the three different types of recycling, what does recycling mean and what problems are there with recycling • Built in obsolescence – what does it mean • Symbols – mobius loop, green dot, eurpoean eco label • Refuse – why should you refuse to use/buy some products • Product life cycle – what are the 6 main stages and environmental considerations at each stage.

  3. Revision Problems with recycling • It is difficult to separate the different materials in some products to allow them to be recycled. • It is sometimes more expensive to recycle old materials than to use new ones. • Environmentally un friendly products can be produced as a by product in the recycling process • Recycled materials are not normally as high quality as new materials.

  4. Recycling – the new conversion of waste products into new materials • A recycled aluminium can saves enough energy to run a television for three hours. • If all the aluminium cans in the UK were recycled there would be 14 million fewer dustbins each year.

  5. Primary recycling – second hand use of items. Examples – charity shops, e bay, giving stuff away to friends/family • Secondary recycling – waste materials are recycled into different types of products. Example – a large corriflute sign could be chopped up and used as plant labels • Tertiary recycling – when products are broken down and reformulated. Example – plastic bottles can be recycled into fibres and then respun to make polyester to make a fleece • Disassembly – reprocessing materials for use in new products

  6. Recyclable materials • Glass • Paper and card • Metals • Wood • Textiles • Electronics • Tyres • Plastics • Food waste

  7. Why should you refuse to use some products? • Toxic chemicals used in the product • Made from a man made source rather than a natural source • Is the manufacturing process safe and appropriate • What about the conditions of working • Packaging and transport distances • May not be good for you

  8. The raw materials: how are they harvested/made? • The production process: how is the product made? • Transport and distribution: you need to consider what, how, where and the cost • Uses: what are the intended uses of the product? How will it be used by the client or customer? • Care and maintenance: what is needed, how much and is it environmentally friendly? • Disposal: the waste from manufacturing or the product itself. Ask yourself the question is it recyclable or biodegradable? Recycling: how can the product be recycled?

  9. The story of stuff (http://www.storyofstuff.com/)

  10. Built in obsolescene A product has designed to become useless or outdated quite quickly. For example throw away plastic cups or a t-shirt with a slogan. Making long lasting products instead would reduce the number of products that a consumer would need to buy. Manufacturers would then make fewer products and so cut down on energy use, transport and materials.

  11. Test • Name 3 materials that can be recycled. (3) • How is recycling different from reusing? (1) • Give an example of primary recycling. (1) • Describe 2 problems with recycling. (2) • What is the difference between secondary and tertiary recycling? (2) • What does built in obsolescence mean? (1) • Why is built in obsolescence usually bad for the environment. (2) • Draw the mobius loop symbol. (1) • What is the name of this symbol? (1) • Describe what this symbol means. (1)

  12. Test 11. Give 3 reasons why you should refuse to use/buy a product. (3) 12. Write down the 6 R’s. (6) 13. There are 6 main stages in a products life cycle. What are they? (6) 14. Describe one environmental consideration for each of the 6 stages of a products life cycle. (6)
