A vermi-processing toilet is a type of toilet in which human excreta is treated through earthworms.
Earthworms convert human excreta into vermicompost or vermin cake which is a good variety of natural manure.
It provides the proper disposal of human excreta thus preventing contamination of the outside environment.
