2. Life Cycle Assessment (LCA) of Materials

Try these first

1. 1.

   What does LCA stand for?

   Hint

   Think about how materials are evaluated over their lifetime.

2. 2.

   Name one of the ISO standards related to LCA.

   Hint

   These standards provide methodologies for assessments.

3. 3.

   What does LCA assess?

   • Only during usage
   • Entire life cycle
   • Only during manufacturing

   Hint

   Think about the full lifespan of a product.

4. 4.

   True or False: EPDs are used to make LCA results more understandable.

   • True
   • False

   Hint

   Consider how we simplify technical information.

5. 5.

   If a new material shows a significant decrease in CO₂ emissions during its lifecycle, but higher energy use during production, how would you assess its overall sustainability using LCA?

   Hint

   Think about how each stage contributes to overall emissions and energy consumption.

6. 6.

   Design a project using the principles of LCA. Select materials that minimize environmental impact across all stages of their lifecycle and justify your choices.

   Hint

   Consider how to balance various factors like cost, availability, and impact.
