Abstract
Hemodialysis (HD) is one of the resource hungry medical interventions. A huge volume of water (about 500 L) and significant amounts of energy (over 7 kW) are used for a hemodialysis session; over a kilogram of waste is produced during this procedure. Thus, HD contributes to global warming while saving patients' lives. In this paper, we showed these crucial points in HD treatment and possible ways (e.g. modifications in dialysate flow rate) to reduce environmental impact maintaining therapy standards.
