Waste oil

Hey there little buddy!

So you know how sometimes we have oil in our cars and the oil gets dirty and we have to change it?

Well, when lots of people do that, we end up with lots of dirty oil that we can't use anymore. That's called waste oil.

But we don't want to just throw it away because it's bad for the environment. So, we recycle it!

First, we separate out any water or other things mixed with the oil. Then, we heat the oil up to really high temperatures.

This makes all the yucky stuff in the oil turn into gas, leaving behind pure oil that we can use again.

And that's how we recycle waste oil! Cool, huh?
