Sustainability

Sustainable design aims to minimise negative impacts on the environment.

Life cycle assessment (LCA)

Life cycle assessment (LCA)

  • Life cycle assessment (LCA) can be used to analyse all the stages in a product’s life and highlight the impact it will have on the environment.
  • The main stages of a Life cycle assessment (LCA) are:
    • Extraction of raw materials.
    • Manufacture and assembly.
    • Transportation.
    • Use.
    • Disposal.

  • The designer can then investigate different ways to reduce the negative impact at each stage. This could include:
    • Alternative materials or manufacturing processes.
    • Sourcing local materials or relocating factories to reduce transportation.
    • Reducing parts.
    • Alternative energy sources.
    • Labelling for recycling.
Finite and non-finite resources

Finite and non-finite resources

  • Resources can be split into two main categories, finite and non-finite resources.
  • Finite resources:
    • Finite resources are not sustainable.
    • They are in short supply and once used will eventually run out.
      • Examples include: oil, gas and coal.
Finite and non-finite resources cont.

  • Non-finite resources:
    • Non-finite resources are sustainable.
    • Can be easily found and once used can be re-grown and replaced.
      • Examples include: wood, wool, cotton.
Disposal of waste

Disposal of waste

  • Waste throughout the products life needs to be reduced.
  • Waste causes environmental damage and growing landfill sites.
Reducing waste

Reducing waste

  • Ways to reduce waste:
    • Recycling schemes with councils for household rubbish.
    • Returning electronic products to companies for disposal.
    • Creating products with re-usable or replaceable parts.
    • Encouraging the use of renewable power sources.
    • Financial incentives for users to refill products.
    • Reducing the amount of disposable products that are used.
    • Using more recycled materials.
