DDalvoy Solutions

All three items contain plastic materials:

I. Cigarette butts: Yes, cigarette filters are made primarily of cellulose acetate, which is a form of plastic. These filters are one of the most common forms of plastic pollution worldwide.

II. Eyeglass lenses: Yes, modern eyeglass lenses are predominantly made from various types of plastic polymers such as polycarbonate, CR-39 (allyl diglycol carbonate), or high-index plastics, rather than traditional glass.

III. Car tyres: Yes, car tyres contain synthetic rubber which is essentially plastic polymer, along with natural rubber, steel belts, and various chemical additives. The synthetic rubber component makes up a significant portion of modern tyre composition.

SUPSC Prelims Strategy and Tips

For plastic identification questions, consider both obvious and hidden sources of plastic. Many everyday items contain synthetic polymers even when they don't appear to be 'plastic' products. Think about modern manufacturing materials.
