A garbage disposal unit (also known as a waste disposal unit, garbage disposer, etc.) is a device, usually electrically powered, installed under a kitchen sink between the sink’s drain and the trap. The disposal unit shreds food waste into pieces small enough—generally less than 2 mm (0.079 in)—to pass through plumbing.
Garbage disposal units are used extensively in American households, but are far less common elsewhere in the world.
