Today, we are going to dive into hazardous waste. Who can tell me what comes to mind when they hear the term 'hazardous waste'?
Is it just any waste that is dangerous?
Good start! Hazardous waste specifically refers to materials that pose a risk to health or the environment. Examples include chemicals and batteries.
So, what makes these wastes hazardous?
Great question! It's their toxic properties or their potential to harm. Remember, we can use the acronym 'CHEM' to remember: Chemicals, Hazardous materials, Elemental substances, Medical waste.
Can you give us more examples?
Certainly! Other examples include medical waste, like used syringes, and solvents used in various industries.

Now that we understand what hazardous waste is, let's discuss how we handle it safely.
What should we do if we find hazardous waste?
You should never handle it yourself. Notify the proper authorities. Disposal requires trained professionals who can manage these materials safely.
What methods do they use for disposal?
Different techniques are utilized including incineration, where waste is burned at high temperatures to reduce volume or even chemical treatment to neutralize harmful substances.
Why is incineration preferred sometimes?
Incineration is preferred because it significantly reduces the amount of waste and can destroy harmful substances, but it must be done under controlled conditions.
