offal

n. useless by-products; parts of an animal that are cut off and discarded in the butchering process; refuse, waste matter

Offal is the entrails and internal organs of a butchered animal. The word does not refer to a particular list of organs, but includes most internal organs other than muscles or bones. Depending on the cultural context, offal may be considered as waste material that is thrown away, or as delicacies that command a high price. Offal not used directly for human or animal food is often processed in a rendering plant, producing material that is used for animal feed, fertilizer or fuel.
