Recycling Metal And Plastic Quiz! MCQ - Quiz

Recycling is the procedure of transforming waste products into new materials and items. It is the best way to reduce harmful gases that lead to air pollution and prevent the garbage from disposing of waste, leading to water pollution. Materials like plastic, metal, electronics, polythenes, etc., can be recycled and convert into new products. This quiz will test your knowledge and make you aware of different ways to recycle metal and plastic.


Questions and Answers
  • 1. 

    Could you put aluminum foil in the recycle bin?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Aluminum foil cannot be put in the recycle bin because it is often contaminated with food residue, making it difficult to recycle. Additionally, aluminum foil is often too thin and may not meet the recycling facility's requirements for recyclable materials. Therefore, it is important to dispose of aluminum foil in the regular trash bin.

    Could you recycle all metal?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Not all metals can be recycled. Some metals, like aluminum and steel, can be recycled indefinitely without losing their properties. However, certain metals, such as mercury and lead, cannot be recycled in the traditional sense and require specialized processes. Additionally, some metal items may contain non-recyclable components, such as plastic or rubber, which would prevent them from being fully recycled. Therefore, it is not possible to recycle all types of metal.

    Rate this question:

  • 3. 

    Which type of plastic is generally considered the most widely accepted and easily recyclable?

    • A.

      Polyvinyl Chloride (PVC)

    • B.

      Polystyrene (PS

    • C.

      Polyethylene Terephthalate (PET)

    • D.

      Polycarbonate (PC)

    Correct Answer
    C. Polyethylene Terephthalate (PET)
    Explanation
    PET is a commonly used plastic for packaging, such as water bottles and food containers. It's widely accepted and easily recyclable because it has well-established recycling processes and can be turned into various products like polyester fibers for clothing or new PET containers.

    Rate this question:

  • 4. 

    Which country recycles the highest proportion of its household waste?

    • A.

       Australia

    • B.

       United Kingdom

    • C.

       Austria

    • D.

      United States

    Correct Answer
    C.  Austria
    Explanation
    Austria recycles the highest proportion of its household waste compared to Australia, United Kingdom, and United States. This means that a larger percentage of the waste generated by households in Austria is recycled, rather than being disposed of in landfills or incinerated. This indicates that Austria has effective waste management and recycling systems in place, which contribute to reducing environmental impact and promoting sustainability.

    Rate this question:

  • 5. 

    Which one of these items was NOT in the top 10 number of pieces of rubbish collected in the 2010 Clean Up Australia Day?

    • A.

       Plastic bags

    • B.

      Metal bottle caps

    • C.

      Cigarette butts

    • D.

      Glass pieces

    Correct Answer
    A.  Plastic bags
    Explanation
    Plastic bags were not in the top 10 number of pieces of rubbish collected in the 2010 Clean Up Australia Day. This suggests that while plastic bags are often considered a major source of pollution, they were not as prevalent or significant in terms of quantity compared to other items such as metal bottle caps, cigarette butts, and glass pieces.

    Rate this question:

  • 6. 

    Why is polystyrene counted separately from other plastic in annual Clean Up surveys?

    • A.

      It floats on water

    • B.

      It is toxic and shreds into tiny particles 

    • C.

      It is a different colour 

    • D.

      All of the above.

    Correct Answer
    B. It is toxic and shreds into tiny particles 
    Explanation
    Polystyrene is counted separately from other plastics in annual Clean Up surveys because it is toxic and shreds into tiny particles. Unlike other plastics, polystyrene breaks down into smaller pieces over time, which can be harmful to marine life if ingested. Additionally, its toxicity poses a threat to the environment. Therefore, it is important to track and address the specific impact of polystyrene in order to develop effective strategies for its management and reduction.

     Which of these items shouldn’t go in the compost heap?

    • A.

      Coffee grounds

    • B.

      Vacuum cleaner waste

    • C.

      White paper bags

    • D.

      Meat scraps

    Correct Answer
    D. Meat scraps
    Explanation
    Meat scraps should not go in the compost heap because they can attract pests and rodents, create foul odors, and take a long time to decompose. Composting is a process that requires a balanced mix of organic materials, such as fruits, vegetables, leaves, and coffee grounds, to break down effectively. However, meat scraps contain high amounts of protein and fat, which can disrupt the balance and slow down the composting process. It is best to dispose of meat scraps in a different manner, such as through proper waste management or by using them for other purposes like making broth.

  • 8. 

    You can recycle most plastic bottles, but should you also recycle the plastic bottle tops?

    • A.

       No

    • B.

      Only in some states

    • C.

      Yes 

    • D.

      Yes, but only if still attached to their bottle

    Correct Answer
    A.  No
    Explanation
    The correct answer is No because plastic bottle tops are often made from a different type of plastic than the bottle itself, which can cause issues during the recycling process. Additionally, the small size of bottle tops can get stuck in recycling machinery and cause damage. Therefore, it is generally recommended to remove the bottle tops before recycling the plastic bottles.

    Rate this question:

  • 9. 

    How many times can glass be recycled?

    • A.

      10 times

    • B.

       Indefinitely

    • C.

      80 times

    • D.

      20 times

    Correct Answer
    B.  Indefinitely
    Explanation
    Glass can be recycled indefinitely because it does not degrade or lose its quality during the recycling process. Unlike other materials, such as paper or plastic, glass can be recycled over and over again without any loss in its properties. This is because glass is made from natural materials like sand, soda ash, and limestone, which can be melted down and reshaped repeatedly. Therefore, there is no limit to the number of times glass can be recycled, making it a sustainable and environmentally friendly material.

    How long does it take (approximately) to recycle an aluminum can?

    • A.

      Seven days 

    • B.

      One month

    • C.

      Two months

    • D.

      Six months

    Correct Answer
    C. Two months
    Explanation
    Recycling an aluminum can typically takes approximately two months. During the recycling process, the can is collected, sorted, and cleaned. It is then shredded into small pieces and melted down to remove any impurities. The molten aluminum is then shaped into new cans or other aluminum products. This entire process usually takes around two months to complete, allowing for the necessary steps of collection, sorting, cleaning, and melting.
