ABSTRACT:
Poultry feces are processed through a digester and a separator to produce undissolved solid material and a liquid filtrate. The solid material contains primarily food undigested by the poultry which is blended with comminuted egg shells, comminuted feathers, nutrients to provide a balanced food and new food to produce feed for fowl or stock. The filtrate is chemically treated for recovery of uric acid precipitate, and the remaining filtrate is used as a bacterial culture to produce bacterial protein. Used liquid from the bacterial culture is used as hydroponic culture to grow green fodder.
