With reference to polyethylene terephthalate, the use of which is so widespread in our daily lives, consider the following statements:

Its fibres can be blended with wool and cotton fibres to reinforce their properties.
Containers made of it can be used to store any alcoholic beverage.
Bottles made of it can be recycled into other products.
Articles made of it can be easily disposed of by incineration without causing greenhouse gas emissions.

Which of the statements given above are correct ?

Select an option to attempt

Explanation

Statement 1 is correct. PET fibres can be blended with cotton or wool to improve properties like wrinkle resistance and durability.

Statement 2 is incorrect. Not all PET containers are suitable for all alcoholic beverages. Some PET can leach chemicals at high temperatures or with certain types of alcohol. It's important to check for specific suitability indicators on the packaging.

Statement 3 is correct. PET bottles are one of the most commonly recycled plastics. They can be reprocessed into various products like clothing fibres, new bottles, or building materials.

Statement 4 is incorrect. Incineration of PET, like most plastics, generates greenhouse gas emissions, including carbon dioxide. While PET has a lower emission profile compared to some other plastics, it's still not a zero-emission disposal method.

Remember: Statements like store any kind of alcoholic beverages are vague & ambiguous, so they ought to be eliminated. Also, incineration of any substance cannot be environment friendly as it would definitely release GHGs. Hence the only Option left is Option A. Therefore, the correct statements are 1 and 3.
