By repeated blood circulation the waste products go to the kidneys very easily. Kidneys filter about 180 liters of fluid / day from this cardiac out put. Most of the fluid is reabsorbed. You get only one to three liters of urine per day normally. Lot of energy is spent in this process. Nature could have developed the mechanism like lungs to filter the blood. Total cardiac out put passes from the lungs. But then any kidney disease would have killed you very easily.
