This study conducts a life cycle assessment (LCA) to compare two fossil fuel-based carbon monoxide production processes: steam methane reforming (SMR) and partial oxidation (POX). For the SMR process, gate-to-gate data was generated through process simulation, while for the POX process, data retrieved from a commercial lifecycle inventory database was modified and utilized. As a result of the cradle-to-gate LCA conducted for South Korea, the SMR process has a lower impact on global warming (1.24 kg-CO2 eq/kg-CO) compared to the POX process (2.4...

The demand for electric vehicles (EVs) is increasing worldwide, and with mandatory recycling of End-of-life batteries, interest in remanufacturing used batteries is also growing. The product structure and physical properties of batteries, determined during the design process, are critical factors in the feasibility, profitability, and environmental impact of battery remanufacturing. This study presents a model to evaluate the remanufacturability of EV batteries from economic and environmental perspectives by integrating considerations of batter...

https://doi.org/10.62765/kjlca.2024.25.2.65

This study analyzes the environmental impact of the epoxy manufacturing system, 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 database. Among the impact categories, climate change was identified as having the greatest influence, primarily due to the effects of Bisphenol A and epichlorohydrin, which are key raw materials in ...

The COVID-19 pandemic significantly increased the consumption of single-use masks globally, resulting in a surge in plastic waste and its associated environmental issues. This study conducts a comparative life cycle assessment(LCA) of single-use masks made of petroleum-based polypropylene(PP) and wood-based cellulose materials to evaluate their environmental impacts by life cycle. The results showed that cellulose-based masks found to be approximately 15.6% lower CO2 eq emission and 38.1% reduced resource depletion than PP-based masks, highligh...

https://doi.org/10.62765/kjlca.2024.25.2.85

This study evaluates the environmental impact of PET and PC water bottles from a life cycle perspective, including the production, use, and end-of-life (EoL) phases. The environmental impacts were analyzed across 11 impact categories at the midpoint level based on the CML-Baseline methodology. For the EoL phases, incineration, landfilling, and recycling (PET only) were considered. Under the considered scenarios, PET bottles had lower environmental impacts than PC bottles in categories such as fossil fuel depletion, acidification, global warming...
