Understanding and quantifying the environmental impact of sterile medical devices: a carbon footprint study of single-use electrosurgical scalpels and their reusable alternatives

Year: 2025

Type: article

Abstract: Background: In France, 25% of healthcare emissions are attributed to the supply of medical devices, underscoring the necessity for the development of more sustainable procurement policies. However, comparing the carbon footprint of different devices, especially single-use devices versus reusable ones, presents challenges. Objective: To assess the carbon footprint of single-use and reusable electrosurgical scalpels over 1 year of use in our hospital setting. Design: A cradle-to-grave analysis was conducted from May 1, 2022, to April 30, 2023. Setting: Nantes University Hospital, France. Main outcome measures: The study quantifies carbon emissions across all life cycle stages: raw material extraction, manufacturing, transportation, use, maintenance, and disposal. For reusable devices, sterilization emissions were allocated based on the total annual workload of the Central Sterile Services Department. Carbon footprint values were derived from direct measurements, manufacturer and supplier data, and literature, with conversions using a public and national database (Base Empreinte, ADEME). Results: e, with 86% stemming from handling at our sterilization unit. Conclusions: These findings are contingent on our hospital's practices and may vary based on several factors. Beyond estimating these carbon footprints, it provides a practical, decision-oriented analysis accessible for hospital leadership and healthcare professionals, supporting institutional change.
