Chapter 12: Taking Charge of Waste

Introduction

The chapter opens with a picture of children and their teacher cleaning a park on National Cleanliness Day. It asks: Why are they cleaning? How is waste created? What do we do with it? Children learn that managing waste is in our own hands, and that we can learn from people and places that manage waste well.

What's in this Chapter

1. How is waste created? In our everyday activities we throw away old clothes, tins, bottles, paper, vegetable and fruit peels, plastic wrappers, pencil shavings, old batteries and much more. Sometimes it ends up in garbage piles around homes, schools and neighbourhoods.

2. Why garbage is harmful. Cows and other animals can die by eating plastic mixed with food. Burning plastic releases harmful gases. Puddles and waste water on roads increase mosquitoes, which spread diseases, and waste water may carry germs. In some places, people have worked very hard to keep their houses and surroundings clean.

3. Reduce. The first rule is to reduce the waste we create. Avoid food and drinks in wrappers or plastic bottles, and use cloth bags instead of plastic bags. "The more things we buy, the more things we throw away." Buy what you need and use it until it is no longer usable. Share old toys and books with those who need them.

4. Reuse. The second rule is to reuse things. Our grandparents made quilts from old sarees and bags from old clothes, and gave clothes to people in need. We can wrap gifts in newspaper or old cloth, use one-side-used paper for rough work, and refill a steel or copper bottle instead of buying water bottles. Children make a paper bag from newspaper: "No scissors! No Glue! Just paper!" They also make a gift from waste material for the person who helps keep the home or locality clean, and say a big "Thank You".

5. A place of pride. Silluk in Arunachal Pradesh has clean, tree-lined roads with no trash. It won an award and is called a "zero waste village". Chhota Narena was one of the first villages to become waste-free, and Indore and Mysuru stand out as clean cities. Children ask elders about the Swachh Bharat Mission.

6. Separate different types of waste. There are two coloured dustbins:

  • Green dustbin: dried leaves, branches, fruit peels, vegetable waste and egg shells. These rot easily, mix with the soil and become compost, food for plants and tiny soil animals.
  • Blue dustbin: things made of metal, glass, plastic and paper. New objects can be made from them. This is recycling.
  • Villages and towns that separate and recycle their waste keep their surroundings clean. Sharp things like broken glass and needles should be wrapped in cloth or paper so that sanitation workers are not hurt.

    7. Keeping our surroundings clean. On National Cleanliness Day (30 January), take a pledge to keep yourself and your surroundings clean, create less waste, and dispose of waste properly. "Want not, Waste not."

    Key Ideas

  • Everyday activities create waste, and unmanaged waste harms people, animals and the environment.
  • Reduce first, then reuse, then recycle.
  • Separate wet waste (green bin) from dry waste (blue bin).
  • Clean villages and cities show that change is possible.
  • Words to Learn

  • Waste (कचरा): things we throw away
  • Garbage pile (कूड़े का ढेर)
  • Reduce (कम करना), reuse (दोबारा उपयोग करना), recycle (पुनर्चक्रण)
  • Compost (खाद): rotted plant waste that feeds the soil
  • Dustbin (कूड़ेदान)
  • Segregate or separate (अलग करना)
  • Zero waste (शून्य कचरा)
  • Pledge (प्रतिज्ञा/संकल्प)
  • Sanitation worker (सफ़ाई कर्मचारी)
  • Tips for Parents & Teachers

  • Keep two bins at home, one green (wet) and one blue (dry), and let your child sort the kitchen waste.
  • Carry a cloth bag and a steel bottle when you go out together.
  • Make the newspaper paper-bag together.
  • Plan a zero-waste birthday party with your child.
  • Thank your local sanitation worker together, perhaps with a handmade gift.
  • Common Mistakes

  • Putting plastic milk packets or bulbs in the green bin. They go in the blue bin.
  • Thinking burning plastic gets rid of it. It releases harmful gases.
  • Thinking recycling comes first. The book's first rule is to reduce.
  • Throwing broken glass loose in the bin. Wrap it so workers are not hurt.
  • 💡 Key Learning Points

    • ✓Everyday activities create waste such as wrappers, peels, bottles, old clothes, shavings and batteries.
    • ✓Unmanaged waste harms animals (plastic), air (burning plastic) and people (mosquitoes and germs).
    • ✓Reduce first (cloth bags, buy only what we need), then reuse (quilts from sarees, newspaper gift wrap, steel bottles).
    • ✓The green dustbin is for waste that rots into compost; the blue dustbin is for metal, glass, plastic and paper to be recycled.
    • ✓Silluk (Arunachal Pradesh) is a zero-waste village; Chhota Narena, Indore and Mysuru show that places can become clean.

    👨‍🏫 Teaching Tips

    • →Remind children of common waste-producing activities, like packaged products, take-away food, plastic and decorations (book's note).
    • →Set up two class dustbins and demonstrate segregation after lunch; children wear gloves and masks.
    • →Make newspaper bags and waste-material gifts; see arvindguptatoys.com for more ideas (book's note).
    • →Hold a mini cleanliness drive in the school ground on or near 30 January, with a class pledge.
    • →Explain that sharp items like broken glass and needles must be wrapped before throwing.
    • →Pair children for the 'clean town vs dirty town' role-play.
    • →Plan a zero-waste class party as a follow-up.
