“…Decoupling analysis assesses the degree of decoupling between the economy and the environment by comparing their respective growth rates. A decoupling relationship occurs when the economy grows faster than the associated environmental consequences, while a negative decoupling relationship indicates the opposite (Xing et al, 2020). The decoupling index between industrial water withdrawal (IWW) and industrial output is calculated using Equation 1:…”

Africa's industries have been developing at a pace more rapid than other continents including Asia over the past two to three decades. This research investigated the industrial water use in 1987–2017 in twenty major African countries, representing some 77% of population and 81% of GDP in Africa. A decoupling analysis of industrial water use from economic growth was also made, and hierarchical cluster analysis (HCA) conducted. Key findings include: (i) HCA could divide the patterns of the countries water use into four groups. The group of Algeria, Tunisia, Angola, and Morocco exhibited the highest average industrial water use per capita in 2017. (ii) An expansive negative decoupling became more significant during the 10-year period from 2008 to 2017. (iii) Population growth, economic development, and industrial structure played a prominent role in driving IWW over the past two decades. (iv) Technological advancements in water conservation varied across countries and periods. Some countries including Kenya, South Africa, Ghana, Egypt, and Tunisia, witnessed more rapid increase in water withdrawal from 2008 to 2017, but less significant progress in water saving technologies. This research might be informative for those decision-makers to formulate sustainable water usage policies in line with Africa's sustainable agenda by the year 2063.

“…Thus, the Tapio model is used in this research. Xing et al (Xing et al, 2020) used the decoupling model to assess industrial development from wastewater in China. The decoupling results show a growing decoupling trend between industrial output and industrial water demand during the last 15 years.…”

“…The main advantages of the LMDI methodology are its theoretical foundations, ease of practice and interpretation, its ability to explain changes of an indicator at a sectorial level, its low data requirement, high adaptability, and consistent aggregation (Ang, 2005; Fujii and Kondo, 2018). Furthermore, it has the advantage of resolving the problem of residual term (part not explained by the model) in the decomposition results and has been widely applied to studies on environmental issues like resource and energy consumption, climate change, CO 2 generation, or waste (Akyürek, 2020; Chen and Lin, 2020; Wen and Li, 2020; Xing et al, 2020). The main disadvantage is that LMDI cannot show how much of the variation in the dependent variable (waste generation) is explained by the chosen explanatory variable (i.e.…”

“…This may be perceived as a concern since the universal goal worldwide is to decouple economic growth from waste generation, and thus the logical assumption of economic activity as a driver may be challenged if no accompanying analysis is performed. Decoupling analysis can describe the dynamic relationship between the economic activity and the environmental impact, while decomposition analysis can effectively identify socio-economic factors that cause environmental pressures (Hang et al, 2019; Xing et al, 2020). To support the inclusion of economic activity in our LDMI model, in our article, we examine whether there is a decoupling of economic activity and waste generation in ELV disposal.…”

In 2018, a total of 6,083,000 end-of-life vehicles (EVLs) with a total weight of 6,732,000 tonnes (including waste parts) were generated in the European Union. These vehicles are a subject of particular attention because of their bulky mass, the hazardous components they contain, and the valuable materials present. This article analyses the quantities of ELVs and parts of ELVs that have been recycled, energy recovered, disposed, and reused to assess the impact of the changes in these management options on the total quantities managed. The analysis covered the statistical data on EVLs in 31 European countries for the period 2006–2018, using a new extended version of the logarithmic mean divisia index (LMDI) analysis model, which allows analysts to compare and analyse different waste management options simultaneously. The results show that the changes in the waste intensities and household final consumption expenditure were the greatest drivers of changes in the total quantities managed, while changes in the quantities recycled, energy recovered, disposed of, and reused had the least impact. All countries met or were close to meeting the targets during the period analysed. Changes in the total quantities of waste managed depended on the economic activity, which influenced the quantities of ELVs generated and their subsequent management.

“…In recent decades, China has made tremendous social and economic growth, which has been accompanied by the increased water consumption, resulting in the generation of a massive volume of wastewater. The total wastewater discharge and municipal wastewater discharge rose from 41.5×10 9 m 3 to 73.5×10 9 m 3 , and from 22.1×10 9 m 3 to 53.5×10 9 m 3 , respectively, between 2000 and 2015 [1], causing serious water pollution, destroying hydrological systems, exacerbating existing water scarcity, creating huge economic losses, and impeding China's economic and social development [2][3][4]. Water contamination is a serious issue that is causing increasing social concern.…”

The main objective of this study was to investigate the efficacy of using the constructed wetland for purification of secondary effluent from a wastewater treatment plant (WWTP) in the eastern district of Anyang, Henan province, China. A Subsurface Flow Constructed Wetland (SSFCW) system was designed and constructed, consisting of 302 SSFCW units (L×W×H = 30×20×1.4 m for each unit) with a treatment capacity of 10 5 m 3 /d. Each unit of the system was planted with equal number of Phragmites australis, Typha orientalis Presl, and Zizania latifolia at the density of 16 plants/m 2 . The average values of the Chemical Oxygen Demand (COD Cr ), Biochemical Oxygen Demand (BOD 5 ), Ammonia Nitrogen (NH 3 -N), and Total Phosphorus (TP) of the effluent sampled from 4 outlets of the system chosen at random for 17 months consistently met the Class III of Environmental quality standard for surface water in China, even during the cold season. According to the economic analysis, the system may generate an annual profit of around ¥ 1.4 million yuan. The SSFCW system is an cost-effective and profitable technique for the further polish of the secondary effluent from the wastewater treatment plant.
