2.2 Product Life Cycle Design Vezzoli 07 08 (28.10.08)

  1. 1. carlo vezzoli politecnico di milano . INDACO dpt. . DIS . faculty of design . Italy Learning Network on Sustainability course System Design for Sustainability subject 2. Introduction to product Life Cicle Design (LCD) learning resource 2.2 Product Life Cycle Design
  2. 2. CONTENTS Minimize the inputs and the outputs Life cycle approach Functional approach Product Life Cycle Design criteria Resources minimisation Low impact resources selection Product life optimisation Material life extension Design for disassembly
  3. 3. <ul><li>… the discipline integrating environmental requirements within the product design process: </li></ul><ul><li>product LIFE CYCLE DESIGN </li></ul><ul><li>(or eco-design, design for the environment, …) </li></ul>
  4. 4. <ul><li>PRODUCT LIFE CYCLE DESIGN: APPROACH </li></ul>an extended design horizon from product design to the design of the product life cycle stages the design “reference” from product design to product’s “ function ” design
  5. 5. <ul><li>LIFE CYCLE DESIGN: (ENVIRONMENTAL) AIMS </li></ul><ul><li>MINIMIZE THE INPUTS AND THE OUTPUTS </li></ul><ul><li>quantitatively </li></ul><ul><li>qualitatively </li></ul><ul><li>( in relation to life cycle and functional unit ) </li></ul>
  6. 6. use service manufac . assemb . finish collection resource’s achieving mater. energy produc. package trasp. storage PRODUCT LIFE CYCLE APPROACH USE PRODUCTION DISPOSING PREPRODUCTION DISTRIBUTION landfill incineration composting recycling reuse comp. reuse remanufactoring other product’s life cycle biosphere geosphere
  7. 7. <ul><li>FUNCTIONAL APPROACH </li></ul><ul><li>IS NOT THE PRODUCT TO BE DESIGNED ( ASSESSED ) BUT, THE WHOLE OF THE PROCESSES ASSOCIATED WITH THE FULFILLEMENT OF A GIVEN FUNCTION </li></ul>
  8. 8. <ul><li>LCD: ENVIRONMENTAL CRITERIA </li></ul> RESOURCES MINIMISATION LOW IMPACT RESOURCES SELECTION PRODUCT LIFE OPTIMISATION MATERIAL LIFE EXTENSION DESIGN FOR DISASSEMBLY
  9. 9. <ul><li>RESOURCES CONSERVATION for future generations </li></ul><ul><li>(ENVIRONMENTAL) IMPACT AVOIDANCE pre-production, production, distribution and disposal of the not used resource quantitative </li></ul>RESOURCES MINIMISATION quantitative impact reduction (life cycle/function) DESIGN FOR:
  10. 10. <ul><li>RESOURCES CONSERVATION/RENEWABILITY for the future generation </li></ul><ul><li>RESOURCES NON TOXICITY AND HARMFULNESS in all life cycle phases </li></ul>LOW IMPACT RESOURCES SELECTION qualitative impact reduction (life cycle/function) DESIGN FOR:
  11. 11. <ul><li>RESOURCES RENEWABILITY </li></ul>DEPENDS ON: - RE-GROWING SPECIFIC SPEED - EXTRACTION FREQUENCY a resource is renewable if: anthropic consumption rate < natural re-growing rate
  12. 12. <ul><li>MATERIALS’ ENVIRONMENTAL IMPACT </li></ul>A RANKING FROM THE BEST TO THE WORST IS “ MISLEADING ” DEPENDS ON: - MATERIAL-SPECIFIC CHARACTERISTICS - CHARACTERISTICS GIVEN TO PRODUCT
  13. 13. <ul><li>PRODUCT LIFE OPTIMISATION </li></ul><ul><li>DESIGN FOR : </li></ul><ul><li>EXTEND ING PRODUCT (AND COMPONENT) LIFE SPAN </li></ul><ul><li>INTENS IFYING PRODUCT (AND COMPONENT) USE </li></ul>

  19. 19. POST-CONSUMPTION RECYCLING PHASES: (COMBUSTION, COMPOSTING) . collection . transportation . separation (disassembly a/o crushing) . identification . cleaning . secondary raw material’s production
  20. 20. <ul><li>MATERIALS’ RECYCLABILITY (COMB., COMPOST.) </li></ul>DIPENDS ON: - SPECIFIC MATERIAL’S CHARACTERISTICS performances recovery (and process costs) - PRODUCT’S ARCHITECTURE - RECYCLING PHASES
