A Study on Life Cycle Environmental Impacts of Multi-Wall Carbon Nanotube

This study conducted a life cycle assessment of the carbon nanotube (CNT) production process, which is widely used across various industries, and explores measures to improve its environmental performance. Additionally, the study conducted an environmental assessment in accordance with the EU PEF methodology to contribute to the establishment of the national LCI (Life Cycle Inventory) database. Among the impact categories, the primary factor contributing to climate change was identified as electricity consumption, the main energy source. To mitigate this, technological development is necessary to reduce carbon dioxide emissions through measures such as utilizing renewable energy, introducing low-carbon processes, and optimizing process efficiency.
