Summary
Chapter 12 of the Class 3 The World Around Us (EVS) NCERT textbook (Our Wondrous World), "Taking Charge of Waste", teaches children how everyday activities create waste and how each of us can help manage it through three key practices — Reduce, Reuse, and separate waste into green and blue dustbins for composting and recycling.
- How Waste Is Created — Everyday activities produce waste such as old clothes, plastic wrappers, fruit peels, paper, pencil shavings, and batteries. When waste is not managed well, it piles up near homes and schools, attracts mosquitoes, and can cause diseases.
- Reduce and Reuse — The first step is to reduce waste by buying only what we need and avoiding unnecessary plastic packaging. The second step is to reuse items — old clothes can become quilts or bags, newspapers can wrap gifts, and bottles made of steel or copper can be refilled instead of replaced.
- Separating Waste — Green and Blue Dustbins — Green dustbins collect wet or natural waste like fruit peels, vegetable scraps, and eggshells, which rot and become compost for plants. Blue dustbins collect dry materials like metal, glass, plastic, and paper that can be recycled into new objects.
- Clean Villages and Cities as Role Models — Silluk in Arunachal Pradesh is called a zero waste village because its residents manage waste so well that its streets look like a garden. Cities like Indore and Mysuru, and villages like Chhota Narena, also stand out as models of cleanliness in India.

Frequently asked questions
01What is Chapter 12 of Our Wondrous World about?
Chapter 12, Taking Charge of Waste, teaches Class 3 children how daily activities create waste and how to manage it by reducing, reusing, and separating waste into the correct dustbins.
02How is waste created in everyday life?
We create waste through activities like eating packaged food, using plastic bottles and bags, sharpening pencils, and buying new things. Items like fruit peels, paper, old clothes, and plastic wrappers all become waste.
03What are the dangers of waste not being managed properly?
Garbage piles attract mosquitoes whose bites can cause diseases. Burning plastic releases harmful gases, and wastewater flowing through roads can carry germs that make people fall ill. Animals like cows can also die from eating plastic mixed with food.
04What does Reduce mean in waste management?
Reduce means creating less waste in the first place. For example, using a cloth bag instead of a plastic bag, avoiding food packed in wrappers, and buying only what you need so fewer things get thrown away.
05What does Reuse mean and how can children practise it?
Reuse means using something again instead of throwing it away. Children can reuse paper that has been written on one side for rough work, refill a steel or copper bottle instead of buying a new one, and make toys or decorations from old newspapers and boxes.
06What is the difference between a green dustbin and a blue dustbin?
The green dustbin is for natural waste like fruit peels, vegetable scraps, dried leaves, and eggshells, which rot and turn into compost. The blue dustbin is for metal, glass, plastic, and paper items that can be recycled into new products.
07What is compost and how is it useful?
Compost is made when green bin waste like vegetable peels and leaves rots and mixes with soil. It acts as food for plants and for tiny animals living in the soil, making it a natural fertiliser.
08Which village is known as a zero waste village?
Silluk, a village in Arunachal Pradesh, is known as a zero waste village. Its roads are so clean and lined with trees that walking through it feels like walking in a garden, and it has received an award for its waste management.
09Are there any other examples of clean places mentioned in this chapter?
Yes. Chhota Narena was one of the first villages in India to become waste-free. Cities like Indore and Mysuru are also noted as standout examples of clean urban areas.
10What is National Cleanliness Day and when is it celebrated?
National Cleanliness Day is celebrated on 30 January. On this day, children are encouraged to take a pledge to keep themselves and their surroundings clean by reducing waste and disposing of it properly.
11How can a child help reduce waste at a birthday party?
The chapter encourages children to think about what waste a birthday party might create — such as plastic decorations and wrappers — and find ways to avoid or reduce it, aiming for a zero-waste party.
12How can children make something useful out of waste material?
The chapter shows that children can make a paper bag out of old newspapers using no scissors and no glue. They can also create toys or decorative gifts using old calendars, bottles, and boxes, and even give these handmade items to the people who help keep their home or neighbourhood clean.
