Content:

1. Methods of Waste Disposal:
   • Landfills: Waste is buried underground in designated areas.
   • Incineration: Waste is burned at high temperatures to reduce its volume.
   • Composting: Organic waste like food scraps is broken down naturally to create compost.
   • Recycling: Waste materials are processed and converted into new products.
2. Definition of Recycling:
   • Recycling is the process of converting waste materials into new, useful products. It helps reduce the amount of waste that goes to landfills and conserves natural resources.
3. Advantages of Recycling:
   • Reduces Waste: Recycling helps reduce the amount of waste that ends up in landfills.
   • Conserves Resources: It saves raw materials by reusing old materials.
   • Saves Energy: Recycling processes use less energy compared to producing new products from raw materials.
   • Reduces Pollution: Recycling reduces the need for waste disposal methods like incineration, which can cause pollution.
   • Creates Jobs: The recycling industry provides employment opportunities.
4. Ideas for Recycling:
   • Pupils can come up with ideas for recycling, such as:
     • Turning old paper into new notebooks.
     • Reusing plastic bottles for storage or crafts.
     • Composting food scraps to make fertilizer for plants.
