How do earthworms get rid of waste?

Earthworms believe it or not have an anus (a bottom) where waste goes through their body and comes out the other end. You learn about the earth worm in Biology class.

If your talking about the trash "waste" earthworms eat the soil and things in the soil and faeces it out. The faeces is very good for the plant and it is called soil. Also the earthworms eat away the "waste" creating holes near the roots of the plant which is important because the plants need carbon dioxide to live.
