What does recirculate mean?
Recirculate means to send something around again, especially by returning it to a system for continued use. The word is especially common in descriptions of engineering, environmental, and industrial processes: a heating system may recirculate warm air, a factory may recirculate cooling water, and a medical facility may recirculate filtered air. It can also mean to circulate information, money, or resources again, often implying renewed distribution or a second pass through an organization. The prefix re- indicates repetition, while circulate refers to movement within a system or to the process of spreading or being passed along. Recirculate is more technical and precise than recycle, because it does not necessarily involve converting waste into raw material. Its usefulness lies in describing systems designed to conserve resources, maintain circulation, or extend the use of an existing stream of material or information.

Where does recirculate come from?
Recirculate was formed in the 19th century by combining the prefix re-, meaning “again,” with circulate, from Latin circulare, “to cause to go around,” derived from circulus, “a little circle.” The related English words circular and circus also trace their roots to the Latin word for a circle or ring. The modern sense developed naturally from the older meaning of circulate, with the prefix emphasizing renewed or repeated circulation.
