Why is it difficult to recycle some metals such as copper?

For example, copper for electrical wiring requires a very high purity, so if wiring is made from recycled copper, the waste copper will need processing before being melted again into copper for wiring. However, steel used in construction doesn’t need such a high purity.

What are some disadvantages of recycling metals?


  • Many of the recycled metals are impure.
  • Sorting metals can cost lots of time and money.
  • Recycling may not meet up to the demands of certain metals so a constant supply will not be met.

What are the disadvantages of using recycled plastics?

Disadvantages of Plastic Recycling

  • People often do not separate their waste in a proper manner.
  • Plastic recycling processes are often quite inefficient.
  • Some items are not recyclable at all.
  • Volatile organic compounds (VOCs) are released into the atmosphere.
  • Melting plastic waste requires significant amounts of energy.

What are disadvantages of recycling copper?

Refining copper is very toxic. During the process, the waste that is emitted to the air can be harmful. Recycling, on the other hand is a relatively safe process and uses up only 15% of the energy that is necessary to refine copper.
