Trends of biowaste generation in hemodialysis units under the hub-and-spoke model: act and save

Abstract

Background To assess the trends of biowaste generation under an unique model of hemodialysis services -Hub and Spoke model. Materials and Methods Biowaste generation including the liquid, solid, recyclable and nonrecyclable wastes are calculated per session of dialysis and tehn calculated per number of sessions in each centre. Biowaste was weighed accordingly using wighing machines normalised to the weight of the material weighed. Results Total waste generated per session was 1007 gm in a maintenance dialysis session and 528 gm in an acute dialysis session. Of this, plastic waste was 847gm and 382 gm in respective units, nonplastic waste was 146 and 160 gm respectively. Based on the number of session in acute unit and maintenance unit, total waste generated in acute unit per day was 18.48 kg and 12.22 kg (plastic, nonplastic) and in maintenance unit, it was 65.45 and 54.05 kgs. Conclusions There is high generation of biowaste in dialysis units with 280–295 tonnes/year. Its the need of hour to plan for green dialysis by bringing in eco-friendly recyclable biowaste.
