Hemodialysis is a resource-intensive treatment characterized by a significant environmental impact. This thesis applies a Life Cycle Assessment (LCA) to quantify the greenhouse gas emissions associated with dialysis activities, following the Greenhouse Gas Protocol, which categorizes emissions into three scopes (Scope 1, 2, and 3). The study is based on data collected from the dialysis department of IRCCS Humanitas Research Hospital, integrated with environmental databases and datasets recognized at the European level, to ensure a methodical and robust assessment. The results highlight that the incineration of plastic waste, the treatment of dialysis wastewater, and patient transportation are the primary contributors to the environmental impact. The analysis indicates that the total environmental impact of the dialysis department, in the current scenario, amounts to 247,048.08 kgCO₂eq per year, with Scope 3 accounting for the largest share of emissions. The study explores various sustainability strategies to mitigate these emissions, focusing on the recycling of medical plastic waste, the reuse of reverse osmosis wastewater, and the optimization of patient transportation. Implementing these measures could mitigate the department’s total emissions by 13.48%, reducing them to 213,745.74 kgCO₂eq per year, with Scope 3 emissions decreasing from 211,564.60 kgCO₂eq to 178,261.26 kgCO₂eq. At the individual treatment level, this would translate into a reduction of the average impact from 15.46 kgCO₂eq to 13.37 kgCO₂eq. This thesis aims to promote a sustainable management approach to dialysis, proposing solutions that can be replicated in other healthcare facilities. The strategies outlined align with circular economy principles and European waste management directives (Directive 2008/98/EC), supporting the objectives of the European Green Deal and the European Strategy for Plastics, while contributing to greenhouse gas emission reduction and the transition toward a more sustainable healthcare system.
L’emodialisi è un trattamento ad alto consumo di risorse, caratterizzato da un impatto ambientale significativo. Questa tesi applica un Life Cycle Assessment (LCA) per quantificare le emissioni di gas serra associate alle attività dialitiche, secondo il Protocollo GreenHouse Gas, che suddivide le emissioni in tre categorie (Scope 1, 2, 3). Lo studio si basa su dati raccolti dal reparto di dialisi dell’IRCCS Humanitas Research Hospital, integrati con banche dati e database ambientali riconosciuti a livello europeo, per garantire una valutazione metodica e robusta. I risultati evidenziano che la termovalorizzazione dei rifiuti plastici, il trattamento delle acque reflue da dialisi e il trasporto dei pazienti in trattamento dialitico costituiscono le principali fonti di impatto. L’analisi ha dimostrato che l’impatto ambientale complessivo del reparto dialitico, nello scenario attuale, ammonta a 247.048,08 kgCO₂eq all’anno, con la categoria Scope 3 che rappresenta la quota più rilevante delle emissioni. Lo studio analizza diverse strategie di sostenibilità per mitigare le emissioni, con un focus sul riciclo dei rifiuti plastici sanitari, il riutilizzo dell’acqua di scarto dell’osmosi inversa e l’ottimizzazione del trasporto dei pazienti. L’implementazione di queste misure potrebbe ridurre le emissioni del reparto dialitico del 13,48%, portandole a 213.745,74 kgCO₂eq all’anno, con un calo delle emissioni di Scope 3 da 211.564,60 kgCO₂eq a 178.261,26 kgCO₂eq. Per un singolo trattamento, ciò comporterebbe una riduzione dell’impatto medio da 15,46 kgCO₂eq a 13,37 kgCO₂eq. Questa tesi si pone come obiettivo una gestione sostenibile della dialisi, proponendo soluzioni replicabili in altre strutture sanitarie. Le strategie delineate sono in linea con i principi dell’economia circolare e le direttive europee sulla gestione sostenibile dei rifiuti (Direttiva 2008/98/CE), supportando gli obiettivi del Green Deal europeo e della Strategia Europea per la Plastica, e contribuendo alla riduzione delle emissioni di gas serra e alla transizione verso un sistema sanitario più sostenibile.

This thesis applies a Life Cycle Assessment (LCA) to quantify the greenhouse gas emissions associated with dialysis activities, following the Greenhouse Gas Protocol, which categorizes emissions into three scopes (Scope 1, 2, and 3). The study is based on data collected from the dialysis department of IRCCS Humanitas Research Hospital, integrated with environmental databases and datasets recognized at the European level, to ensure a methodical and robust assessment. The results highlight that the incineration of plastic waste, the treatment of dialysis wastewater, and patient transportation are the primary contributors to the environmental impact.
