Recycling Metal And Plastic Quiz! MCQ

2.

Could you recycle all metal?

True
False

Correct Answer

A. 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.

Australia
United Kingdom
Austria

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

Plastic bags
Metal bottle caps
Cigarette butts
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.

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

It floats on water
It is toxic and shreds into tiny particles
It is a different colour
All of the above.

Correct Answer

A. 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?

Coffee grounds
Vacuum cleaner waste
White paper bags
Meat scraps

Correct Answer

A. 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.

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

No
Only in some states
Yes
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.

How many times can glass be recycled?

10 times
Indefinitely
80 times
20 times

Correct Answer

A. 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.

Six months

Correct Answer

A. Two months

Recycling an aluminum can typically takes approximately two months. During the recycling process, the can is collected, sorted, and cleaned.

This entire process usually takes around two months to complete, allowing for the necessary steps of collection, sorting, cleaning, and melting.
