Life cycle Assessment of different waste electric vehicle battery reuse strategy – a case study in Taipei

Urbanization has led to significant shifts in both natural resource utilization and human activities. The equilibrium between energy and other resources has been disrupted by the concentration of urban populations and the environmental repercussions of economic growth. This issue is of paramount importance on both global and regional scales. Among the various facets of urban life, the transportation sector, an indispensable urban function, is predominantly associated with issues such as pollution, traffic congestion, and inadequate public transportation systems.This research presents a framework for achieving sustainable development objectives in urban transportation by phasing out diesel-powered vehicles in favor of electric ones. The implementation of electric vehicle policies holds the potential to mitigate urban air pollution. Nonetheless, if the government fails to consider the interplay between various policies during the evaluation process, unintended environmental consequences may emerge.   For instance, while electric vehicles that supplant traditional gasoline and diesel counterparts do not emit pollutants during their operation, they may shift the burden to power plants, necessitating a more diverse range of resources. As such, a comprehensive assessment of the overall environmental impact becomes imperative. Hence, in this study, we initially focus on motorcycle batteries as a case in point. We employ methodologies such as material flow analysis, life cycle assessment, and real-world factory inventory to examine the resource consumption across various stages of battery production. Subsequently, we gauge the implications using distinct sustainability and environmental management criteria pertinent to diverse urban settings and resource management strategies. The resulting data is then amalgamated into a comprehensive environmental assessment.   In addition, we account for variations in battery reuse rates, such as repurposing them as energy storage units. Ultimately, these scenarios are scrutinized to gain insight into the divergent environmental repercussions associated with different reuse approaches
