“…Sichuan's coal consumption had been steadily declining for several years, but rebounded in 2019, leading to a significant increase in regional material consumption (DMC). This phenomenon shows that energy prices have a direct impact on material consumption, which is consistent with previous studies 40 …”

“…This phenomenon shows that energy prices have a direct impact on material consumption, which is consistent with previous studies. 40 It can be seen from Fig. 4(c) the overall efficiency of solid waste is relatively stable from the perspective of the entire southwestern region and reached its highest point in 2015.…”

Circular economy is beneficial to solve the conflict between the environment and development. The study combines the material flow in human society with the evaluation of the regional circular economy. Through the evaluation method combining DEA and rank‐sum ratio, the development level of circular economy in this area is evaluated from both vertical and horizontal perspectives (time level and space level). The result shows: (1) from the point of view of material input, direct material input, total material demand and total material consumption all show an upward trend. The overall resource input is relatively large. (2) In terms of material output, the emission is increasing. But the growth rate is relatively slow. The emission reduction effect is outstanding. The resource output rate showed a continuous growth trend. Economic development is less dependent on the massive consumption of natural resources. (3) In terms of material circulation, the import volume of natural resources outside the province in the southwest region increased. Solid waste recycling is not high. (4) Judging from the evaluation results, the development level of Sichuan's circular economy is relatively stable. Followed by Chongqing and Guizhou. However, the level of development in Yunnan fluctuates greatly. The material consumption rate in Southwest China is higher than the economic growth rate. Resource input and resource consumption are still relatively large. Although some environmental indicators have improved, there are still serious resource and environmental problems in the future economic development of the western region that need to be paid attention. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

This study investigates the synchronization of pumping operations with dynamic energy prices in hinterland drainage systems. Employing mathematical models and optimization techniques, the research systematically evaluates the inherent flexibility within regular pumping operations. While traditional approaches often focus solely on tidal dynamics to enhance energy efficiency, this study introduces a more comprehensive perspective. Beyond the conventional scope, it incorporates a nuanced analysis of electricity price patterns, aiming to promote grid-friendly behavior and foster an adaptive and efficient response to fluctuating energy availabilities. By delving into these complex interplays, the research not only deepens the understanding of hinterland drainage system dynamics but also proposes an approach for robust and sustainable operational practices. Moreover, the holistic approach aligns with the broader objective of reducing CO2 emissions, reflecting a commitment to environmentally responsible infrastructure management. Through this balanced exploration of operational optimization potentials, the research contributes to the scientific discourse on energy-efficient and environmentally conscious practices in hinterland drainage systems.
