Lastly, we will cover **Landfilling** and **Incineration**. Can someone explain what landfilling is?
It's where waste is buried in the ground, right?
Correct! While landfilling isolates waste, it can lead to environmental issues like leachate and greenhouse gases. What about incineration?
That's burning waste to reduce its size!
Exactly! Incineration can effectively decrease the volume of waste and destroy harmful substances, but it raises air pollution concerns. A mnemonic to remember is **L.I.E**: Landfills Isolate, Incineration Eliminates.
What are the downsides of each method?
Great question! Landfills can lead to soil and air pollution, while incineration can emit harmful gases. Overall, understanding these waste management methods is crucial for effective waste reduction practices.

Chapter Content
- Reduce
○ Minimize waste production by using fewer resources.
Detailed Explanation
Reducing waste involves using fewer resources to produce less unwanted material. This can be achieved by making smarter choices, such as buying only what you need and avoiding unnecessary purchases. By reducing consumption, we lessen the amount of waste generated in the first place.
Examples & Analogies
Think of reducing waste like cooking only enough food for your family. If you prepare just the right amount, you won't have leftovers to throw away. Similarly, if we only buy what we need, we create less waste.
Reusing Items
