Try these first

1. 1.

   What does the term 'circular economy' refer to?

   Hint

   Think about what happens to materials after their life is over.

2. 2.

   Why is aluminum a good material for recycling?

   Hint

   Consider how many times a material can be reused.

3. 3.

   What is one key characteristic of a circular economy?

   • Minimizing waste
   • Increasing production
   • Maximizing emissions

   Hint

   Focus on the purpose of a circular economy.

4. 4.

   Is aluminum recyclable indefinitely?

   • True
   • False

   Hint

   Think about how many times something can be reused.

5. 5.

   Propose a new building design that maximizes the use of aluminum and incorporates design-for-disassembly principles. Outline key features.

   Hint

   Think about how to make removal easy and efficient.

6. 6.

   Calculate the reduction in carbon emissions if a construction project opts to reuse aluminum materials instead of sourcing new materials. Assume the emission savings from recycling aluminum is 95%.

   Hint

   Consider the difference in emissions using both processes.
