In some cities and towns, municipalities provide separate dustbins for collecting two kinds of garbage. Usually one is coloured blue and the other green. The green bin is for materials such as :

Question

Accepted Answer

In many cities and towns, municipalities have implemented a system of waste segregation to promote recycling and proper waste management. This system often involves the use of two separate dustbins, typically colored blue and green, to collect different types of waste. The green bin is specifically designated for biodegradable waste, which includes organic materials that can decompose naturally and be converted into compost.

Option 4, "Plant leaves (dried)," is the correct answer because plant leaves are organic and biodegradable. They can decompose naturally and are suitable for composting. When plant leaves are collected in the green bin, they can be processed into compost, which enriches the soil and supports plant growth. This aligns with the purpose of the green bin, which is to collect biodegradable waste.

Now, let's examine why the other options are incorrect:

1. Plastic water bottle: Plastic is a non-biodegradable material and does not decompose naturally. It is typically collected in the blue bin, which is meant for recyclable materials like plastics, metals, and glass. Therefore, plastic water bottles do not belong in the green bin.

2. Glass: Glass is another non-biodegradable material that does not break down naturally. It is recyclable and should be placed in the blue bin. Glass does not belong in the green bin, which is reserved for organic waste.

3. Iron rod: Iron is a metal and is non-biodegradable. It is recyclable and should be disposed of in the blue bin. Iron rods do not belong in the green bin, as they do not decompose and are not organic waste.

In conclusion, Option 4, "Plant leaves (dried)," is the correct choice for the green bin because it represents biodegradable waste that can be composted. The other options are non-biodegradable materials that should be placed in the blue bin for recycling.
