Correct answer: (c)


All over the world, a three-way segregation of waste is followed; these are the red, green, and blue bins.

Green bins are used for wet waste, which comes from the kitchen, cooking food, goes to one bin, like peels of fruits and vegetables, seeds, etc.

Blue bins are used to dispose of dry recyclable waste such as newspapers, cardboard, packing plastics, bottles, cans, etc.

Red bins are used to dispose of rejected waste, which does not belong to the above two categories, including biowastes like diapers and bandages, which should go into a third bin.

Plastic bags, metal chips, screws, and nuts are non-degradable, so they should be transferred to a landfill. Vegetable peels and eggshells are biodegradable, so they should be transferred to a composting pit. Newspapers and journals can be recycled, so they should be transferred to the recycling unit.
