Understanding Plastic Decomposition and Recycling

What is the main challenge with recycling PET using traditional methods?

• Recycling PET releases harmful chemicals.

• Recycled PET cannot be used for carbonated beverages.

• Recycled PET is not as visually appealing or durable.

• It is too expensive to recycle.

What is the role of the enzyme PETase in the decomposition of PET?

• It melts PET into a liquid form.

• It breaks down PET into smaller components.

• It combines PET with other materials.

• It prevents PET from crystallizing.

Why can't bacteria naturally produce the combined super enzyme?

• The super enzyme is toxic to bacteria.

• Bacteria do not have access to PET in nature.

• Bacteria lack the necessary genetic material.

• The super enzyme is too large for bacterial production.

What is a major limitation of the new super enzyme in commercial applications?

• It can only decompose low-quality plastics.

• It requires rare materials to function.

• It is not fast enough for commercial viability.

• It is too expensive to produce.

What is a crucial step humans must take to improve plastic recycling?

• Ensure plastics reach recycling facilities.

• Develop new types of plastics.

• Increase the use of single-use plastics.

• Ban the use of PET in all products.
