The unprecedented technological development and economic growth over the past two decades has resulted in streams of rapidly growing electronic waste (e-waste) around the world. As the potential source of secondary raw materials including precious and critical materials, e-waste has recently gained significant attention across the board, ranging from governments and industry, to academia and civil society organizations. This paper aims to provide a comprehensive review of the last decade of e-waste literature followed by an in-depth analysis of the application of material flow analysis (MFA) and life cycle assessment (LCA), i.e., two less commonly used strategic tools to guide the relevant stakeholders in efficient management of e-waste. Through a keyword search on two main online search databases, Scopus and Web of Science, 1835 peer-reviewed publications were selected and subjected to a bibliographic network analysis to identify and visualize major research themes across the selected literature. The selected 1835 studies were classified into ten different categories based on research area, such as environmental and human health impacts, recycling and recovery technologies, associated social aspects, etc. With this selected literature in mind, the review process revealed the two least explored research areas over the past decade: MFA and LCA with 33 and 31 studies, respectively. A further in-depth analysis was conducted for these two areas regarding their application to various systems with numerous scopes and different stages of e-waste life cycle. The study provides a detailed discussion regarding their applicability, and highlights challenges and opportunities for further research.

Inputs And Outputs

In order to study the development of regional recycling economy, the material inputs and outputs of the eco-economic system in Shandong Province during the period from 1996 to 2009 were systematically analyzed by the material flow analysis(MFA). The results show that, (1)excluding water, material inputs and outputs rose persistently, but both were lower than the rate of GDP growth. (2)Water supply had a turning point in 2003, from 25.239 billion tons down to 21.934 billion tons, followed by the total annual water supply has been maintained at 220 million tons. At the same time the amount of wastewater emissions is increasing, especially domestic wastewater emissions had faster growth and that increased pressure on the regional water environment;(3) Steady increase in material input intensity, material output intensity presented a first increased and then decreased trend, that showed since Shandong Province proposed the strategic planning to develop circular economy, the development of regional circular economy have improved the material utilization efficiency and made a material reduction in output in the case of material input growth achieved. The rapid increase of material input and output efficiency further illustrated the efficiency of resource comprehensive utilization and waste output have been significantly improved.
