Welcome to our presentation on "Life Cycle Assessment of an ultramicroelectrode array sensor for trace metal measurement in water, a cradle-to-gate approach". This presentation was given at the 22nd ACM International Conference on Computing Frontiers (CF'25) for the Sustainable Computing Workshop (SCW25). In this video, presented by Jean Schoch, a life cycle assessment of an electrochemical sensor is shown, comparing a gold-based version with a carbon-based one.


Abstract : The environmental impact of manufacturing an electrochemical measurement system is evaluated using Life Cycle Assessment (LCA). This study focuses on identifying the most impactful materials and processes with the aim of eco-design on manufacturing an ultramicroelectrode array sensor: reducing environmental impacts through process modification, material changes and reducing electricity consumption. A cradle-to-gate approach is used. The results highlight that metal (i.e., gold and titanium) and insulator deposition are the most impactful steps for the gold-based sensor. The most impactful steps for the carbon-based sensor are pyrolysis and the insulator deposition. The environmental impacts are mainly due to the high electricity consumption.
