“…During electrochemical oxidation, solid metals are in contact with the anode (possibly as a slurry "painted" on the electrode 105 ), while electrodes are immersed in the solvent. The electrochemical oxidation of metal oxides occurs possibly through formation of superoxide 106 (O 2 − ), for example in the case of zinc oxide, as illustrated in eqn (7):…”

“…An abundant literature is available on metal recycling from WEEE, where authors mainly aim to recover precious metals from printed circuit boards (PCBs). However, WEEE suffers from poor levels of recyclability 4,5 which can be linked to high statistical entropy [6][7][8] and low metal content, and ultimately unfavourable economics. The amount of TCMs in WEEE is generally low, and taking into account the low collection rates, absence of detailed material stack information about various state-of-the-art products (adhesives and encapsulants), and difficulties to recycle the products, it unfortunately oen leads to almost negligible recovery.…”

“…In addition, in calculating the development level of regional CE, the evaluation index system is constructed to provide a quantitative index, and it is applied to empirical analysis to evaluate the development level of regional CE (Tang et al 2020 ). This quantitative method includes weighted entropy, which can measure the recyclability of urban solid waste in China (Tong et al 2021 ).…”

Compared with the linear economy, the circular economy can solve the contradiction between social development and resource utilization, which has attracted wide attention. Although the relationship between transportation infrastructure and economic development has changed from traditional mode to spatial mode, the spatial effect of transportation infrastructure on regional circular economy is still unclear. By combining the policy changes for developing the circular economy in China, this study constructs a comprehensive index of circular economy development in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). Based on the time and space development of the circular economy in GBA, we analyze the spatial effect of transportation infrastructure on it. The results show that the regional circular economy in GBA has developed, but has not been decoupled from economic development. The development of the regional circular economy presents a positive spatial spillover effect, which is beneficial to the building of the regional recycling market. The improvement of transportation infrastructure has a positive impact on the circular economy of neighboring cities, but it may have the risk of inhibiting the development of the local circular economy. These findings provide policy recommendations for urban planners to coordinate the development of transportation infrastructure and circular economy.
