Biosolids

Biosolids are poop that gets turned into a useful thing. When people go potty, the poop goes down the toilet and into big pipes that carry it to a special place where it's treated with helpful bacteria to get rid of any germs or bad stuff. After that, the poop turns into something like dirt that can help plants grow better.

This new dirt-like stuff is called biosolids, and it's used to help make soil better for growing plants. It has important nutrients like nitrogen and phosphorus that plants need to grow strong and healthy. Some people even use biosolids in their gardens or on their lawns to help their plants grow better.

So basically, biosolids are a way to turn something yucky like poop into something that can help make our world a little bit better.
