Recycling & Protecting Earth

Recycling & Protecting Earth

Even the trash we throw away every day can become useful again when we sort it by type. Separating things made of different materials, like paper, plastic, glass, and cans, into the right bins is called recycling. Recycling well saves resources and makes less trash, so our Earth becomes much cleaner. On this page you can sort different objects into bins and see how it works.

Let's Sort Trash!
0 Paper
♻️ Why Sort Trash?
①Sort by type → can be reused
②Saves resources for new things
③Less trash = cleaner Earth!
Where Does This Go?
📰 Paper
①Newspaper, boxes, books, notebooks
②Only clean ones (no glue or food)!
③Recycling paper saves trees
♻️ Plastic
①PET bottles, shampoo bottles, plastic cups
②Wash clean before disposal
③Remove labels if possible
🫙 Glass / Can
①Glass bottles, cups → Glass
②Drink cans, tin cans → Metal
③Separate caps
How to Protect Earth
🌍 What We Can Do
①Sort trash well
②Save water and electricity
③Plant trees and flowers
④Use reusables instead of disposables
⑤Do not waste food
🌱 Small Actions = Big Change!
①One person reduces 1kg trash/day
②30 classmates → 30kg/day!
③1 year → about 10,000kg — huge!
④Not "one less", but "starting with me!"
Summary
🎯 Recycling & Earth Protection Summary
①Sort: paper, plastic, glass, cans, general
②Wash clean to recycle
③Save water/electricity + reduce disposables
④Earth is one — we must protect it!
⑤Start with small actions!
