Unsustainable production and consumption patterns in China's metropolitan areas have resulted in an increase in the production of waste materials for which local governments have to find solutions, one of which is the construction of waste incineration power plants. These plans often meet resistance from residents who fear negative environmental impacts . This paper presents an in-depth study of how Chinese local governments responded to an environmental conflict regarding the construction of an incineration power plant in Panyu district, Guangzhou City, PRC, using a typology to identify and categorize these government responses. The empirical analysis shows that local governments engage in various new ways of dealing with these conflicts. The article aims to enhance insight into the response of Chinese local governments to these conflicts and provide building block for further research.

At the 2022 Beijing Winter Olympics, the concept of sustainable development impressed the world. This study is supported by the concept of ecological protection and conservation. The easily available plastic bottled Coca-Cola® was innovatively proposed as a low-cost solvent to greenly exfoliate bulk tungsten disulfide (WS 2 ). First, an overview of two-dimensional (2D) WS 2 was given, summarizing the related reports on its structures and synthesis. Taking into account the yield of 2D flakes, the optimal fabrication environment was figured out. The related characterizations of the cola-synthetic WS 2 were studied. This work opens up a new strategy for the inexpensive and green exfoliation of 2D crystals with a high yield.

Reclaiming the spent graphite (SG) in the anodes of end-of-life lithium-ion batteries (LIBs) is of tremendous significance for addressing resource shortage and eco-friendliness. The impurities embedded into the graphite interlayer after multiple charge–discharge cycles hinder the free migration of lithium ions, resulting in inferior lithium storage capacity. Herein, a space-confined intercalation of deep eutectic solvent (DES) strategy is proposed, to dissolve the impurities by utilizing its great ability to form hydrogen bonds (O–H…Cl - , O–H…O and O–H…F) with PVDF binder, SEI film and the residual electrolytes within the SG, simultaneously enlarging the interlayer distance to upgrade the anode graphite. After the further pyrolysis, the as-obtained mildly expanded graphite (MEG-800) exhibited well-defined graphite microcrystalline layer structure and high graphitization degree. The moderately enlarged graphite layers provided more space for the insertion and extraction of lithium ions, endowing MEG-800 with exceptional performance in LIBs, such as extremely high charge capacity of 477.4 mAh/g at a current density of 0.1 A/g and superior reversibility and desirable cycle stability. After 100 cycles at 0.1 A/g, its capacity still retained 470.9 mAh/g with a Coulombic efficiency as high as 99.76 %. The structure-dependent lithium-ion diffusion features of MEG-800 were also examined by electrochemical kinetics analysis . This study opened up a prospective avenue for the green and efficient recycling of spent anode graphite in retired LIBs, offering a solution to the problem of shortage of battery materials and promoting sustainable development.

Bamboo is a sustainable and environment-friendly polymer. In order to investigate the effect of photoaging on the service-life of bamboo, ultraviolet aging (UV-aging), light-avoidance −90 %RH (AL-90 %RH), light-avoidance (AL) and control were continuously monitored for 26 weeks under four kinds of light conditions. The surface color, micro-morphology and surface interfacial composition of comparing various bamboo samples during storage. The results showed that the total color difference for the cortex (9.758 ± 0.712) and pith (1.325 ± 0.075) under AL conditions were lower than the other three sets of storage conditions, and L* values were reduced by 56.42 % and 53.73 %, respectively. In addition, microflora and grooves were formed on the surface of bamboo stored under AL-90 %RH conditions. Meanwhile, catheters were the main channels for the propagation of mycelium in bamboo. Moreover, the Cox/unox value (an oxygenated to unoxygenated carbon ratio of 0.964) increased sharply under these conditions. UV-aging destroyed the texture and structure of bamboo tissue cells and surfaces, degraded the surface lignin content by 18.89 %, and exposed more observable hemicellulose and cellulose functional groups, thus increasing the carbon binding energy and becoming more difficult to degrade. Finally, the Long Short-Term Memory (LSTM) neural network model was used to predict the fading of the surface color and the volatile compounds after aging, and different photoaging color indication systems were established. Exploring the aging mechanism of bamboo during storage is important for promoting the development of bamboo industry and replacing plastic products, and helping in determine the practical applications of the proposed strategies, their economic benefits and limiting of bamboo photodegradation under optimal warehousing conditions. This meet the current requirements of sustainable development by preserving bamboo resources and use instead renewable resources for both environmental and economic benefit.

Since 2000, solar thermal utilization (STU) has a great process in China, not only with a large scale commercial development, but also with an increasing number of scientific publications and patent applications. In this paper, several representative technologies of STU in China are studied based on an analysis of the relationship between patents and policies. Patent information of STU is collected and analyzed in terms of the time distribution, type distribution and technical trends. The main driving factor—energy policy—was discussed through the patent analysis . STU patents took off after the millennium and 85.8% of them came from the solar water heater . For conventional technologies, 94.2% of the granted patents were from companies and individuals, and the patents proposed by various research institutions were mainly in the technological beginning and technological maturity. Advanced technologies are still at a growth stage in China, and they have 412 patents in all and 70.5% of the patents were from systematic design and test method. Energy policies have played a significant role in promoting the progress of STU in China. Based on a patent analysis, it can be expected that STU will enter the age of medium-high temperature in China.
