Medical waste management - how industry can help us to protect environment and money?

Background: The global climate change and its consequences force us to remodel our processes and rethink the current model of providing the HD treatments. Waste management have a massive impact on the environment and the economy. Every HD session produces above 1 kg of medical waste, which should be properly stored and destroyed. In particular in the pandemia time we should improve the dialysis unit budget as well as decrease CO₂ emission produced during the waste elimination.Materials and Methods: The checked the weight of different dialyzers used regularly in dialysis centers in Poland. The Kern CM 320-IN scale was used for the measurement. The measurement accuracy was 0.1 g. Also the filling volume of each dialyzer has been taken into consideration.Results: The dialyzers were divided into four groups depending on the surface. 1,4m2 in group one, 1.5-1.6 m² in group two, 1.7-1.8 m² in group three and finally 2.0-2.2 m² in group four. FX class dialyzers were lightest in every group. The heaviest ones were Polyflux dialyzers. The difference between the lightest and heaviest dialyzers was about 95 g. The filling volume was lowest in FX dialyzers and the highest in Elisio dialyzers. The difference was 20 mL.Conclusions: The weight of different dialyzers available on the market differs. The decision-makers should take into account this fact as the additional quality feature. In extreme cases the weight difference reaches 95 g. In yearly perspective, the usage of the lighter dialysis set can cause the 17 million kg decrease of medical waste and significant savings.
