Improving water reuse efficiency from a recycling perspective is claimed to be a better way to alleviate global water scarcity and water pollution. This study opens the internal "black box" of China's water reuse system driven and decomposes water reuse system into water use, wastewater treatment and reclaimed water reuse stages, and selects input-output indicators based on SDG6. Then, it proposes a dynamic three-stage DEA model to assess the water reuse efficiency. A spatial Durbin model is constructed to explore the impact of extreme temperatures on water reuse efficiency. The findings reveal a slight increase trend of water reuse efficiency from 2011 to 2021, with the efficiency of the reclaimed water reuse stage outperforming that of the water use and wastewater treatment stage. Provinces located in the water-scarce and water-medium regions have better water use efficiency. The efficiency of wastewater treatment and reclaimed water reuse stage generally continue to improve, and the degree of polarization decreases. Additionally, extreme high and average temperatures have significant influence on the water reuse efficiency, while, extreme low temperature has no effect on water reuse efficiency in the short term. Extreme high temperature has an significant spatial spillover effect. Overall, this study provides valuable insights into the complex interlinkages within the water reuse system and highlights the importance of considering these relationships when improving the system efficiency.

Photothermal disinfection (PTD) offers promising potential for water purification due to its sustainable and broad-spectrum bactericidal properties, although it is hindered by slow charge separation in photosensitizers. Herein, we present a plasma-mediated PTD technique utilizing an efficient localized heating effect induced by incident light at specific wavelengths for rapid bacterial inactivation. A metallic CuS photosensitizer, derived from electronic waste through a biomimetic transmembrane confined-assembled strategy, facilitates collective and coherent oscillation of free electrons around Cu atoms in the near-infrared range.

National and international guidelines call for greater environmental sustainability in agriculture through the introduction of the circular economy. Recent studies investigate the introduction of new technologies and methodologies in the field, however, few focus on initial stages at the plant nursery or the management of the involved materials, and none scientifically calculate their environmental impact. To fill this gap, this paper focuses on an Italian case study that quantifies the environmental impact of the traditional seed trays used worldwide for growing, transporting and transplanting tomato seedlings, proposing and evaluating two alternatives from a circular economy perspective.

Water reuse is a viable option to address temporal or structural water shortages. However, the ubiquitous presence of chemicals of emerging concern (CECs) in natural systems, especially the aquatic environment, represents a significant obstacle to water reuse and the receiving environment. Therefore, an extensive literature review was performed to identify current water reuse practices at field scale, reported types and levels of CECs and their associated risks for human and environmental health.
