1.2. Recycling Approaches

Try these first

1. 1.

   What happens to crushed concrete?

   Hint

   Think about what recycled concrete can become.

2. 2.

   Name one use for recycled wood.

   Hint

   Focus on the alternative uses of wood.

3. 3.

   What is one way concrete can be recycled?

   • Sell it
   • Use it as aggregate
   • Throw it away

   Hint

   Think about how we can reduce waste in construction.

4. 4.

   True or False: Recycling aluminum saves more energy than manufacturing new aluminum.

   • True
   • False

   Hint

   Consider the energy costs of recycling versus raw production.

5. 5.

   Calculate the reduction in energy use if a construction project recycles 100 tons of aluminum versus producing new aluminum. Assume producing new aluminum requires 14,000 kWh per ton.

   Hint

   Think about the amount of energy saved per ton when recycling.

6. 6.

   Assess the environmental benefits of implementing wood recycling in a local construction project. What metrics would you use to measure improvement?

   Hint

   Consider how each measure impacts sustainability and conservation.
