1. A food waste disposer comprising:
a housing;
a grinding device inside the housing to grind food waste;
an exhaust fan inside the housing to form an air flow;
an exhaust pipe connected to the exhaust fan to form an exhaust flow path along which air introduced from the grinding device flows via the air flow formed by the exhaust fan;
a filter assembly to adsorb contaminants from the air flowing along the exhaust flow path;
a branch pipe branching from the exhaust pipe between the grinding device and the exhaust fan to form a connection flow path that communicates with the exhaust flow path; and
a sterilization device connected to the branch pipe and configured to:
selectively open and close the connection flow path, and,
with the connection flow path being open, generate and supply plasma to the exhaust pipe through the connection flow path via an intake airflow formed by the exhaust fan.
