“…In this context, the government promoted research and development activities involving air pollutant abatement technologies in the industrial sector and exhaust emission controls for automobiles. In addition to air pollutant problems, the Chinese government allocated a large budget for water quality improvements (Fujii and Managi, 2017). These allocations increased the incentive to develop water pollution abatement technologies for future environmental markets based on expanded governmental budgets.…”

Sustainable green technology is an important contributor to creating a sustainable society by simultaneously promoting environmental conservation and economic development. This study examines the determinants of sustainable green technology invention in China, with a focus on the differences in green technology development priorities in each five-year plan period. This study uses patent publication data in a patent decomposition analysis framework. We find that sustainable green patent publications increased due to efficiency improvements, the prioritization of sustainable green patents, an increased R&D expenditure share and economic growth, especially during periods of gradual economic development in China. Additionally, we find that the relative priority of R&D shifted from renewable energy technology to pollution abatement and other sustainable green technology in the 12 th five-year plan. The different R&D priority trends for sustainable green technologies among the five-year plans can be used to formulate effective policies that promote sustainable green technology invention.

“…Additionally, Yang and Li [36] calculated the total factor efficiency of wastewater control in different industrial sectors in China between 2003 and 2014. Fujii and Managi [37] used the weighted Russell directional distance model to evaluate the efficiency of industrial wastewater management in China between 2004 and 2014. Also using the DEA model, Li et al [38] calculated green TFP for each industrial sector in China from 2001 to 2011 by estimating the Global Malmquist-Luenberger (GML) index using a Slacks-based Measure-Directional Distance Function (SBM-DDF).…”

This paper investigated the factors driving the changes in industrial wastewater emission intensity (IWEI) across provinces in China. To do this, we proposed a Super-efficiency Slacks-based Measure-Global Malmquist Index (SSBM-GMI) to decompose the change in IWEI into the effects from efficiency change (ECE), technological change (TCE), capital–wastewater substitution (KWE) and labor–wastewater substitution (LWE). The method was applied to conduct an empirical study using Chinese provincial data from 2003–2015. The main findings include the following: firstly, TCE was the dominant driving force behind the reduction in IWEI with an average annual contribution of −6.4% at the national level, followed by KWE (−5.3%), LWE (−1.8%) and ECE (1.2%). Secondly, significant differences exist in the driving factors behind the reduction in IWEI across regions. The reduction in IWEIs in the Northeast area and the Great Northwest area was mainly driven by productivity growth, while the reduction in IWEIs in the other areas was mainly driven by factor substitution. Thirdly, the shortage of KWE and LWE has impeded IWEI reduction in the Great Northwest area, the Middle Reaches of the Yellow River, the Northeast area and the North area. Finally, some particular policy implications were also recommended for reducing industrial wastewater emission in China.

“…When the pharmaceutical compounds reach water (wastewater, rivers, and oceans), they affect the aquatic species [18] and life itself. Among the most important pollution sources, the untreated hospital and industrial effluents [19,20] and the improper disposal of used or expired pharmaceuticals [21] can be mentioned.…”

In this study Fe3O4@C matrix was obtained by combustion method and used hereafter as adsorbent for paracetamol and acetylsalicylic acid removal from aqueous solutions. The Fe3O4@C matrix was characterized by electronic microscopy, X-ray diffraction, thermal analysis, Fourier-transform infrared spectroscopy, and magnetic measurements. Two kinetic models of pseudo first-order and pseudo-second-order for both paracetamol and acetylsalicylic acid were studied. The experimental data were investigated by Langmuir, Freundlich, and Redlich–Peterson adsorption isotherm models. The adsorption followed the Redlich–Peterson and pseudo-second-order models with correlation coefficients R2 = 0.98593 and R2 = 0.99996, respectively, for the adsorption of paracetamol; for the acetylsalicylic acid, the adsorption followed the Freundlich and pseudo-second-order model, with correlation coefficients R2 = 0.99421 and R2 = 0.99977, respectively. The equilibrium was quickly reached after approximately 1h for the paracetamol adsorption and approximately 2h for acetylsalicylic acid adsorption. According to the Langmuir isotherm, the maximum adsorption capacity of the magnetic matrix was 142.01 mg·g−1 for the retention of paracetamol and 234.01 mg·g−1 for the retention of acetylsalicylic acid. The benefits of using the Fe3O4@C matrix are the low cost of synthesis and its easy and fast separation from solution by using an NdBFe magnet.
