System där liv kan upprätthållas i ett slutet rum genom återanvändning av tillgängliga produkter, i synnerhet med hjälp av ett kretslopp där koldioxid, urin och andra spillprodukter genom kemiska reaktioner eller fotosyntes omvandlas till syre, vatten och föda.
Systems that provide for the maintenance of life in an isolated living chamber through reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (NASA Thesaurus, 1988)
