What is pyrolysis?

Pyrolysis is when something turns into new stuff just by getting really hot, and no oxygen gets in the way.

Imagine you have a marshmallow on a stick, and you put it in a campfire, but you cover it with a lid so no air can reach it. The marshmallow starts to get super gooey, then turns into a crunchy, dark brown charcoal-like thing. That’s like pyrolysis!

In pyrolysis, heat is the main character. When you apply high heat without oxygen, things break apart and rearrange themselves. This can make new materials, sometimes useful ones! For example, when you cook potato chips, they’re kind of doing a simple version of pyrolysis: heat turns them crispy and golden.

Sometimes, people use pyrolysis to make things like charcoal from wood or even plastic into useful chemicals. It’s like giving stuff a really hot bath in a sealed room, and when they come out, they’re not the same anymore!
