Hi there! Chemical waste refers to all the harmful stuff that is left over when we use chemicals. Just like how you have garbage left over after you finish eating, we have chemical waste left over after we finish using chemicals. The chemicals can be things like cleaning agents, pesticides, paints, and other things that we use every day.
The problem with chemical waste is that it can be very dangerous to people, animals, and the environment if it's not handled properly. For example, if we throw chemicals down the drain, they can end up in rivers and lakes and make the water harmful for fish and plants to live in. If we don't dispose of chemicals safely, they can also leak into the soil and cause long-term damage to the environment.
So, people who work with chemicals and companies that produce chemicals have to make sure they follow very strict rules and guidelines for how to handle and dispose of chemical waste. This includes things like storing the waste in special containers, transporting it safely, and making sure it gets treated and disposed of in a safe way.
In summary, chemical waste is the leftover waste from things like cleaning products and pesticides, and it can be harmful to people and the environment if not handled properly. People who work with chemicals must follow strict rules to dispose of chemical waste safely.
