What are blue coloured bins used for?
Blue bins are used for collecting materials that can be recycled.
There is a three-way segregation of waste followed all over the world, these are 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 ad 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 should go into a third bin.
Examples:
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.
