“…Rivers are important carriers of freshwater resources that maintain the biosphere water cycle, regulate nutrient migration and accumulation, and promote energy balance, and they also play a major role in hydrological conditions and sustainable ecological development (Gelwick 2000 ; Xu 2017 ; Pukšec et al 2019 ). Rivers experience a gradient of environmental conditions caused by natural variables, such as climate, topography, and geology, and the intensification of anthropogenic activities caused by cascade hydropower development and industrial and agricultural construction.…”

The Heihe River is a typical inland river under increasing anthropogenic pressure. To explore the characteristics of the macrobenthic assemblages and their relationships with environmental factors in the upstream and midstream regions of this basin, abiotic conditions and macrobenthic assemblages were investigated in the summers of 2018 and 2019. A total of 50 species were collected, and Arthropoda and mollusks were the dominant groups. A significant increase in standing stock was observed from the upstream to midstream, and predators (PR) were the main functional feeding group. A one-way analysis of variance (ANOVA) revealed that the Shannon-Wiener index and Margalef’s index values significantly differed at the spatial scale (P < 0.05). A redundancy analysis (RDA) and Pearson correlation analysis showed that the spatial heterogeneity of the macrobenthos was influenced by the biochemical oxygen demand (BOD5), water temperature (WT), total nitrogen (TN), salinity, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), and potassium permanganate index (CODMn) (P < 0.05). The spatial variation of macrobenthos was mainly governed by natural conditions and human disturbances.

“…In conclusion, the authors pointed out that the installation of optimised and heat-integrated two-stage vacuum evaporation process, within the biogas production plants, could result in a circular and economically viable waste management technology. Recently, two Special Issues based on the circular economy track at the SDEWES conference [72,73], attracted the interest in seeking inspiration and concrete solutions for a sustainable future.…”

“…With the transition away from fossil fuels accelerating as the world moves through the 21st century, 'green technology' such as PV cells plays a vital role in a low carbon future dominated by a mix of renewable energy generation technologies [12,13]. However, the growth of PV technology brings about a new challenge of end-of-life (EoL) management of PV panels.…”

Life Cycle Assessment of Disposed and Recycled End-of-Life Photovoltaic Panels in Australia

et al. 2021

This study presents a life cycle analysis (LCA) of end-of-life (EoL) photovoltaic (PV) systems in Australia. Three different EoL scenarios are considered for 1 kWh of electricity generation across a 30-year PV system lifespan: (i) disposal to landfill, (ii) recycling by laminated glass recycling facility (LGRF), and (iii) recycling by full recovery of EoL photovoltaics (FRELP). It is found that recycling technologies reduce the overall impact score of the cradle-to-grave PV systems from 0.00706 to 0.00657 (for LGRF) and 0.00523 (for FRELP), as measured using the LCA ReCiPe endpoint single score. The CO2 emissions to air decrease slightly from 0.059 kg CO2 per kWh (landfill) to 0.054 kg CO2 per kWh (for LGRF) and 0.046 kg CO2 per kWh (for FRELP). Increasing the PV system lifespan from 30 years to 50 and 100 years (a hypothetical scenario) improves the ReCiPe endpoint single-score impact from 0.00706 to 0.00424 and 0.00212, respectively, with corresponding CO2 emissions reductions from 0.059 kg CO2 per kWh to 0.035 and 0.018 kg CO2 per kWh, respectively. These results show that employing recycling slightly reduces the environmental impact of the EoL PV systems. It is, however, noted that recycling scenarios do not consider the recycling plant construction step due to a lack of data on these emerging PV panel recycling plants. Accounting for the latter will increase the environmental impact of the recycling scenarios, possibly defeating the purpose of recycling. Increasing the lifespan of the PV systems increases the longevity of the use of panel materials and is therefore favorable towards reducing environmental impacts. Our findings strongly suggest that PV recycling steps and technologies be carefully considered before implementation. More significantly, it is imperative to consider the circular design step up front, where PV systems are designed via circular economy principles such as utility and longevity and are rolled out through circular business models.
