It is a fact that if you drink from a plastic bottle and throw it in the dustbin, it will still be there when your grandchildren are old. What is the reason behind this?
Plastics are biodegradable.
Plastics are radioactive.
Plastics are non-biodegradable.
Plastics are heavy metals.
Plastics are non-biodegradable.
Plastics are synthetic polymers primarily composed of long carbon chains, which are not recognized by natural decomposers like bacteria and fungi. Because these microorganisms lack the specific enzymes required to break the strong covalent bonds in plastic, these materials persist in the environment for hundreds to thousands of years.

Think of a plastic bottle like a stainless steel spoon; just as you wouldn't expect a metal spoon to rot in your compost bin, plastic persists because it doesn't 'feed' the microorganisms in the soil.
(C10тАЛH8тАЛO4тАЛ)nтАЛ тАФ The repeating monomer unit of Polyethylene Terephthalate (PET)
The lack of biodegradability arises from the chemical structure of polymers such as Polyethylene Terephthalate (PET). Nature typically breaks down organic matter through hydrolysis and microbial oxidation, but the synthetic, highly stable carbon-carbon backbone of plastics resists these biological degradation pathways, leading to persistence in landfills.
Plastics are synthetic polymers derived from petrochemicals.
Biodegradation requires biological organisms to break down chemical bonds.
Photo-degradation can break plastic into smaller microplastics, but it does not remove them from the environment.
Non-biodegradable waste contributes significantly to ocean pollution and landfill mass.
High durability for packaging
Lightweight and moisture resistant
Environmental persistence
Microplastic contamination in food chains
Toxic emissions if incinerated improperly
Single-use beverage containers
Food storage packaging
A standard plastic water bottle can take roughly 450 years to decompose in a landfill.
Option A is wrong because plastics are synthetic, not organic food for bacteria.
Option B is wrong because plastics are not radioactive; radioactivity is a nuclear property.
Option D is wrong because plastics are organic polymers, not heavy metals like Lead (Pb) or Mercury (Hg).
C is correct тАФ Plastics are non-biodegradable.
Always distinguish between 'degradable' (breaking into smaller pieces, like microplastics) and 'biodegradable' (chemically consumed by living organisms).
