Operating rooms are facing the arrival of a plethora of disposable mini-invasive surgical devices (MISDs) often made from nonbiodegradable materials that may be liable for the negative impacts on the environment. The estimation of their CO2e is central to empowering the healthcare supply chain. To propose a standardized methodology for estimating the embodied carbon footprint (CF) of disposable MISDs and their application in transurethral benign prostatic hyperplasia (BPH) surgery. METHODS: The proposed methodology relied on a partial product lifecycle assessment and was restricted to a specific part of Scope 3, which comprised the manufacturing of MISDs- and non-device-associated products (packaging/user manual) (NDAPs). The process-sum inventory method was used. The seven latest disposable MISDs used worldwide for transurethral prostatic surgery were dismantled, and each piece was categorized, sorted into the appropriate raw material group, and weighed. The CF was estimated according to the formula: activity data (weight of raw material) x emission factors of the corresponding raw material (kg CO2e/kg). RESULTS: The total weights of disposable packaging and user manuals ranged from 0.062 to 1,492 kg. Plastic was the most common and least emissive raw material (2.38 kg CO2e/kg) identified. The estimated embodied CF of MISDs ranged from 0.07 to 3.3 kg CO2e, of which 9 to 86% was attributed to NDAPs (Figure 1). Rezūm MISD had the most CO2e due to the multiplicity of its components. Despite its technical simplicity, the disposable plasma loop was found to have the third highest CF due to the manufacturing of cables designed to support a high electric amperage. The lowest use of raw materials was found for the iTind and HoLEP devices, which were also found to have the lowest estimated CO2e compared to the other devices. CONCLUSIONS: This study described a simple and independent calculation method for estimating the embodied CF of MISDs, regardless of country speciAcations. Using this method, our results showed a wide discrepancy in the estimated CO2 emissions of the most recent disposable MISDs for transurethral BPH surgery.
