Abstract

This study investigates the multifaceted landscape of green building practices, focusing on their factor structure and cluster characteristics concerning environmental responsibility and urban livability. A comprehensive analysis identifies distinct factors and clusters, each representing different dimensions of sustainable urban development. This study embarks on an exploration of the complex domain of green building practices, employing Exploratory Factor Analysis (EFA) and k-means clustering to dissect the factor structure and clustering characteristics pertinent to environmental responsibility and urban liability. The factors encompass environmental sustainability and urban convenience, highlighting the delicate balance between ecological consciousness and urban functionality. Delving into demographic variables like income, higher education, age, and marital status, our findings reveal statistically significant correlations, emphasizing the pivotal role these individual characteristics play in shaping preferences towards green building practices. Specifically, our analysis crystallizes into two primary clusters. Cluster 1 emphasizes the essence of "Environmental Sustainability," marked by a strong inclination towards energy efficiency, sustainable materials, and green spaces, reflecting a commitment to ecological stewardship. In contrast, Cluster 2, denoting "Urban Convenience and Access," underscores the importance of proximity to public transport, shopping centres, and workplaces, encapsulating a desire for accessibility and convenience in urban design.

Abstract

The term "electronic waste" or "e-waste" refers to a broad array of discarded electronic products and electrical appliances that have reached the end of their useful lives. These include computers, smartphones, televisions, and refrigerators. Over the past three years, the volume of e-waste has surged, from 24.9 million metric tons (MMT) in 2019 to 33 MMT in 2022, as reported by the United Nations in The Global E-Waste Monitor 2024. This increase is driven by the expansion of the electronics industry and the increased usage of electronic devices. Life Cycle Assessment (LCA) and Material Flow Analysis (MFA) are key methodologies used to assess the environmental impact and material flow of e-waste management, respectively. However, many MFAs fail to track the flow of secondary materials that are reused, recycled, and reduced in the new products. This study addresses these gaps by analyzing e-waste management trends in Asia using a systematic literature network analysis (SLNA). SLNA combines a systematic literature review (SLR) and bibliometric analysis (BA) to offer a comprehensive review from various perspectives. This study aims to identify underexplored topics and trends, provide insights that can shape future research directions, and inform government policies on e-waste management in Asia.
