Taking Charge of Waste
The chapter 'Taking Charge of Waste' in Class 3 EVS introduces young learners to the meaning of waste and the importance of keeping our surroundings clean. Students learn about different types of waste generated at home and school, such as leftover food, paper, plastic, and peels. The chapter highlights the difference between biodegradable (wet) and non-biodegradable (dry) waste and teaches the simple habits of reducing, reusing, and recycling. For Bihar Board (BSEB) exams, understanding waste management helps students build strong foundational values about environmental cleanliness and sanitation, which frequently appear as short-answer questions and practical identification tasks.

What is Waste?
Unwanted or useless things that we throw away after use are called waste, such as old papers, broken toys, and vegetable peels.
Wet Waste (Biodegradable)
Kitchen waste like fruit and vegetable peels and leftover food that easily rot and mix with the soil are called wet waste.
Dry Waste (Non-Biodegradable)
Materials like plastic bags, metal cans, and glass bottles that do not rot easily and stay in the environment for a long time are dry waste.
Using Two Dustbins
We should always use a green dustbin for wet waste and a blue dustbin for dry waste to help in easy disposal and recycling.
Reduce, Reuse, and Recycle
To save our Earth, we should create less waste (reduce), use old things again in creative ways (reuse), and send materials to factories to make new things (recycle).

Frequently Asked Questions
Why do we need two different dustbins?
We use two dustbins to separate wet waste (which rots and makes manure) from dry waste (which can be recycled).
What should we do with vegetable peels?
Vegetable peels should be put in the green dustbin as they are wet waste and can be used to make compost for plants.
How can we reuse old things at home?
We can use empty plastic bottles to make small flower pots or pencil stands instead of throwing them away.
