Environmental damage cost can measure the impact of pollution caused by human activity on final safeguard subjects from endpoint perspective. Application of environmental damage cost to municipal solid waste (MSW) management is still rare. To fill such a research gap, this study established a MSW environmental damage cost assessment method using Life Cycle Impact Assessment Method based on Endpoint (LIME) model. Four types of environmental damage cost, namely, primary productivity, social assets, biodiversity and human health for waste treatment were investigated in the city of Shanghai. Results show that the environmental damage cost was 113.7, 116.9, 140.0, 144.0 and 170.8 million dollars in Shanghai from 2014 to 2018, respectively. Damage cost of social assets was the dominant component, accounting for about 55%. Landfill mainly caused social assets damage cost, while incineration mainly caused human health damage cost. Scenarios analysis further revealed that after implementing MSW separation, the total environmental damage cost could be reduced by about 1/3. The best MSW treatment method is fermentation, followed by compost, incineration and landfill, with unit environmental damage cost being 0.22, 4.51, 16.04 and 23.47 USD/ton, respectively.

Fast urbanization and economic prosperity generate huge amount of municipal solid waste (MSW). It is therefore critical to identify the determinants of greenhouse gas (GHG) emissions from MSW treatment and prepare potential GHG mitigation measures. A combined System Dynamics - Logarithmic Mean Divisia Index model is developed to identify the driving forces of GHG emission generated from MSW treatment and explore the mitigation potentials. Shanghai, a typical megacity in China is selected as a case study. Results showed that economic development, population scale and emission intensity were driving forces to induce GHG emissions from MSW treatment, while generation intensity and treatment structure were the factors to mitigate GHG emissions from MSW during 2000–2017. Scenario analysis further revealed that landfill gas utilization and MSW separation improvement were the most effective measures in reducing GHG emissions from MSW treatment, leading to about 88.07% and 85.48% of reduction compared with the business-as-usual scenario in 2050. Scenarios of improving incineration rate, reducing per capita MSW generation and restricting population growth will reduce GHG emissions by 72.29%, 30.06% and 0.30%, respectively. Utilizing landfill gas, improving MSW separation and promoting green behaviors are suggested to mitigate GHG emissions from MSW treatment.

Greywater is found to bring higher water pressure than freshwater consumption, thus grey water footprint (GWF) has received great attention as a comprehensive indicator to assess wastewater pollution. Industrial park is an important source for wastewater discharge, but few GWF studies have been conducted at the industrial park level due to lack of data availability. To fill such a gap, this study develops one GWF assessment model at the industrial park level by considering wastewater sources from enterprises, wastewater treatment plant (WWTP), residents and agriculture. Such a model is then tested in the Changzhou Economic and Technology Development Zone (CETDZ). Results show that non-connected enterprises were the dominant sources for wastewater discharge, particularly in terms of total phosphorus (TP) and NH3-N pollution. The critical pollutants for GWF in CETDZ include total nitrogen and TP, which are mainly from rural towns. The top ten companies for GWF are identified, which can help the local government to prepare more appropriate wastewater control policies. Several mitigation measures, including increasing connection rate of the non-connected enterprises, controlling key enterprises, recycling wastewater from WWTP, and reducing the background concentration of natural water bodies, are investigated, in which increasing connection rate is identified as the most effective one. Finally, several policy recommendations on increasing connection rate, such as implementing river dredging projects and artificial wetland technology, are proposed.

Sustainable crop production is a significant challenge in China. To achieve this goal, it is necessary to evaluate environmental impacts related to the sustainable development of crop production by integrating scientific and practical indicators. Therefore, this study employed emergy and index decomposition analysis approaches to assess the environmental impacts of non-point source pollution and the overall performance of crop production in China’s 31 provinces. First, the emergy flow of emission impacts and two new indicators, the emergy sustainability index and the emergy-based pollutant-producing coefficient, were proposed to comprehensively measure crop production performance from 2012 to 2015. The results demonstrated that the environmental impacts of non-point source pollution (EIN) were predominantly attributed to total nitrogen and phosphorus contents and mulching film residuals, which substantially increased the total emergy used and reduced the sustainability of crop production in each province. The ratio of EIN plus purchased resources (F) to total emergy used (U) were consistently greater than 80% in all 31 provinces, while the ratio of local resources including the emergy of local renewable (R) and non-renewable resources (N) to the total emergy was relatively small, accounting for less than 20% in all provinces. Then, a logarithmic mean Divisia index decomposition method was applied to identify the key driving forces influencing the evolution of EIN. The decomposition analysis indicated that the economy factor had a major promoting effect on EIN growth in all provinces except Beijing and Shanghai. Intensity and technology factors had a limiting effect on EIN growth. These findings provide valuable insights for developing appropriate crop production policies that consider local conditions.

Municipal solid waste (MSW) management and recycling has become an emerging issue in developing countries. Shanghai, the largest megacity in China, is well-known nationwide due to leading China’s MSW separation and recycling. Therefore, this paper introduces the Shanghai mode for MSW management and its current situation to enrich existing MSW management studies. Results show that the total generation volume of MSW and amount of MSW generation per capita were 9.00 million tons and 372.16 kg in 2017, increased approximately eight-fold and four-fold compared with the data in 1978, respectively. The MSW treatment rate reached 100% since 2014, with incineration rate increased to 48.56% in 2017. The cost of MSW management after implementing MSW sorting regulation is increased to 985 CNY/ton, including 390 CNY/ton of MSW sorting cost. Then three key features and innovative MSW management modes, namely, mandatory MSW sorting legislation, Green Account program, and the Combined Network program are introduced. Meanwhile, two main challenges are urgent to be responded, including inadequate collecting vehicles and limited wet waste treatment capacity. Finally, policy recommendations on strengthening MSW recycling process, constructing complete terminal treatment industry, and making systematic policies were provided to respond existing challenges.

The grey water footprint (GWF) can be used to connect wastewater quality and quantity, making it a powerful tool for policy makers and those responsible for managing wastewater systems. As a supplementary to existing GWF research, this study explores the GWF evolution of eight economic regions in China by taking into consideration the GWF of livestock feeding. In addition, we use the logarithmic mean division index method to study the background driving forces of GWF in primary industry for eight economic regions. Results show that the overall GWF in China fluctuates from 6082 billion m3 to 6238 billion m3 between the years 2003 and 2015. Primary industry contributes most to the GWF because of livestock feeding, particularly for the northwest economic region, accounting for 84.81% in 2015. The southwest economic region has the highest total GWF, and east coast region has the lowest total GWF. An analysis of driving forces shows that economic scale and industrial structure are the driving forces that best explain the GWF for the East coast, middle of Yellow River, Northwest, and Southwest economic regions. The effects of economic scale and pollution producing intensity are driving the GWF in the Northeast Regions. For the North coast and middle Yangtze River Regions, economic scale, industrial structure, and pollution producing intensity are driving forces for GWF. While for the South coast region, population is an important contributor apart from economic scale and industrial structure. Policy implications from perspective of the agriculture GWF and endowment of different regions were finally discussed.

Shanghai is the first city to implement Municipal Solid Waste (MSW) sorting regulation in China, and it also has policies on economy, demography, MSW collection and treatment. Therefore, it is crucial to understand the impacts of these polices on MSW management for Shanghai. System dynamics model is a prevailing method to simulate impacts of various policies on MSW management from a dynamic and complex perspective. Besides, different from existing studies that consider only a certain process of MSW management, our system dynamic model simulate the entire process of MSW production, sorting, collection and final treatment. Seven scenarios are set to simulate the impacts of these policies. Results show that economic policy has great impact on future MSW management. MSW generation in 2035 will decline by 3.25 Million tonnes if Gross Domestic Production growth rate decrease by 1%. Demographic policy will reduce MSW generation per capita, but increase the total amount of MSW generation. MSW sorting policy will decrease total demand of MSW landfill, but soar the demand of food waste treatment facility. Treatment method policy will not play a big role in decreasing total demand of MSW landfill. Finally, policy implications including prudent economic and demographic policy, strengthening biochemical treatment capacity and comprehensive utilization of residues are proposed. It is anticipated that this system dynamic model and policy implications can contribute to the MSW management of other 45 Chinese cities that are planning to implement sorting regulation soon, or even other global cities.

The establishment of recycling network is critical to improve municipal solid waste (MSW) management. However, how to determine the best locations for the recycling stations and recycling centers remains to be solved. Under such a circumstance, this study aims to forecast the MSW generation and develop a cost-based location optimization model using p-median method so that the optimal scale and location of recycling centers can be identified. Shanghai, with an ambitious plan for promoting MSW recycling at the city level, was selected as a case study city. Results show that Shanghai's MSW generation rate will be about 3% from 2017 to 2020. Regional distribution analysis shows that the downtown areas have higher intensity for MSW generation due to high population density and consumption level. Fourteen regional recycling centers were identified to be the optimal places for establishing recycling centers. The achievement of this scenario can lead to the lowest total cost of 144 million Chinese Yuan. Moreover, the optimal results may change if unit transportation cost and unit scale cost are changed. For instance, the optimal numbers of recycling centers will increase with the increase of unit transportation cost or decrease of unit scale cost. Finally, model limitations and policy recommendations are raised by considering the local realities.

Incineration has been regarded as a promising method to respond to municipal solid waste (MSW) challenges. However, its high cost and health impacts are the main barriers to the development of incineration. This study aims to investigate the cost-benefit of MSW incineration in 31 Chinese provinces to identify the regional disparity of incineration policy in China. Life cycle environmental impacts and costs were analyzed using the life cycle assessment software Gabi 8.0 and method CML-2001. Results show that MSW disposal costs, Global Warming Potential (GWP) and Eutrophication Potential (EP) will decline significantly with the increase in incineration rate for all Chinese provinces, while the environmental impacts of Human Toxicity Potential (HTP), Ozone Layer Depletion Potential (OLDP) and Terrestric Ecotoxicity Potential (TETP) increase the trend. Economically developed and populated provinces such as Guangdong, Jiangsu, Zhejiang and Shandong have both a higher incineration volume and incineration potential. As for the cost-benefit analysis, developed provinces such as Guangdong, Chongqing, Shanghai and Tianjin exhibit the highest cost-benefit in toxic impacts of HTP, TETP and ODP. Northern provinces such as Jilin, Xinjiang, Heilongjiang and Hebei have the lowest cost-benefit in toxic impacts but have the highest cost-benefit in GWP and EP. Finally, policy remarks on incineration cost, priority provinces, integration of sorting and incineration are also discussed.

It is important to promote energy saving and resource conservation in cities to promote sustainable development. Urban-industrial symbiosis (UIS) strategy is one of the effective ways to reduce resource consumption and carbon emission in the city. However, rather few studies focusing on both the cost benefit of waste treatment optimization and the heat loss of the energy network optimization in the UIS system. In this study, a typical industrial city Shenyang was selected, and the proposed UIS system included an optimized waste treatment system and industrial system. The results indicate that (1) Steam transportation limited the energy saving effects of the UIS system and economic factor played a key role in the waste treatment method transition. The investment payback time of change the MSW treatment method from landfill to waste power generation and to steam generation was 7.7 years and 11.1 years, respectively. (2) Through UIS implementation, Shenyang city could recover 8.05 × 106 GJ of energy from UIS system and reduce the carbon emission by 1.3%. This study provides quantitative analysis to understand the energy savings and emissions reduction potential of UIS practices, and critical insights into the feasibility of its application in the cities of developing countries.

Efficient energy recovery from burnable solid waste is considered an important component in a low-carbon society. Herein, we discuss the optimization of energy recovery from waste and how to reduce the environmental load of waste. First, we introduce the concept of upgrading waste-to-energy (WtE) processes to improve the exergy efficiency of society as a whole and provide guidance for selecting and combining the most appropriate technology for transforming waste-to-energy. We then propose a methodology called resource life-cycle assessment (LCA) that can be used to properly evaluate the effect of upgrading WtE processes and to optimize waste utilization not only within a given factory or municipality but also within society as a whole. Finally, we present two case studies with which we examine the direct and indirect upgrading of WtE processes and use resource LCA to quantitatively analyze the CO2 reduction achieved by upgrading WtE processes compared with that achieved by conventional WtE processes. The analysis of these case studies shows that upgrading WtE processes would result in approximately 50%–100% greater reduction in fossil fuel input compared with conventional waste power generation, which means that we expect a 50% to 100% greater reduction in CO2 emissions and the concomitant savings in fuel cost. The concept of upgrading WtE processes and resource LCA is useful for selecting a cost-effective option to improve the exergy efficiency both in developed countries and in developing countries, many of which need to contribute to their Nationally Determined Contribution under the Paris Agreement.

Many water footprint studies have been conducted on those water scarce regions to respond their water crisis, while water rich regions also face water sustainability challenges due to inadequate water management or being virtual water exporter. Therefore, this paper tries to clarify the water footprint and detail virtual water flow features of a water-rich province, namely Yunnan province in China, to pursuit for more enlightenment for water conservation of not only water scarce regions but also water abundant regions. Multi-regional input-output (MRIO) method was adopted for water footprint and virtual water flow calculation. Results showed that the total water footprint of Yunnan was 11.35 billion m3, with 7.98 billion m3 (70%) of internal water footprint, demonstrating that Yunnan was a high water self-sufficient province. Moreover, Yunnan was a net virtual water exporter with a value of 1.18 billion m3, which was not good for Yunnan but was good for water scarce provinces. As for the detailed virtual water flow trade, high water intensity Guangxi, Hunan, Xinjiang were the top three net importers of Yunnan, while low water intensity Guangdong, Shanghai and Zhejiang were the top three export provinces of Yunnan. This did not affect Yunnan, but was not a good phenomenon for water sustainability of whole China. Moreover, agricultural sector was found to be the dominant sector for both virtual water import and export, accounting for about 88% and 86%, respectively. To maintain sustainable water management of both Yunnan and China, policy insights on keeping Yunnan as a net virtual water exporter, making use of its advantage in green water, adjusting trade structure by considering provincial water intensity were proposed.

Grey water footprint (GWF), as a measure of water pollution in terms of the amount of water needed to dilute pollutants, has drawn great attention due to the necessity to respond to water contamination and water scarcity challenges. Under such a circumstance, this study aims to reveal China's national and provincial GWF features from 2003 to 2015, and to identify the corresponding driving forces by using the Kaya equation and the Logarithmic Mean Division Index (LMDI) decomposition method. Results show that the national total GWF declined from 1418 billion m3 in 2003 to 1655 billion m3 in 2015, and the industrial GWF reduction was the main reason for this decrease. Domestic GWF was the dominant component, particularly for service dominated provinces such as Beijing, Shanghai, Hainan, etc., with proportion up to about 80%. Southern and eastern provinces had higher GWF but lower GWF intensity (GWF per unit GDP), and water scarce northern provinces exhibited higher GWF load although they had lower GWF. The GWF intensity experienced a decreasing trend, with economy effect and intensity effect being the main driving forces, particularly for Tibet. Technology effect and exploitation effect (ratio of water use to water resource) were the main barriers for less developed provinces. Finally, policy recommendations are proposed to alleviate future GWF challenges of China, such as improving the discharge standards of WWTP (wastewater treatment plant), promoting wastewater recycling, reducing GWF intensity and GWF load through industrial structure and trade structure adjustment.

With a growing demand for crop products in China, a great deal of local resources and industrial inputs are consumed including agricultural machineries, chemical fertilizers, pesticides, and energies, which results in many environmental issues such as resource depletion, water pollution, soil erosion and contamination, and CO2 emissions. Thus, this study evaluated the trend of sustainability of China’s crop production from 1997 to 2016 in terms of emergy and further explored the driving forces using decomposition analysis methods. The results showed that the total emergy used (U) increased by 50% from 7.82 × 1023 in 1997 to 1.17 × 1024 solar emergy Joule (sej) in 2016. Meanwhile, the values of the emergy sustainability index (ESI) were all smaller than one with a declining trend year by year, indicating that China’s crop production system is undergoing an unsustainable development pattern. From the results of the ESI decomposition, the renewable resource factor (R/GDP) and land use factor (L/A) are two key factors impeding the sustainable development of the crop production system. Therefore, the increased capacity of renewable resources and enough labor forces engaged in crop production will be the key strategies for its sustainable development.

Year 2005 is important because it is the base year for the international carbon reduction commitment and national development plans for China. However, accurate and robust CO2 emission data for 2005 remain limited, particularly for city-level emissions. To address these gaps, we established a uniform city-level CO2 emission inventory for all the 287 prefecture-level cities in China for 2005, combining the High-Resolution Emission Gridded Database (CHRED) 2.0, statistical data and onsite survey. The results showed that Shanghai, Tangshan, Beijing, Tianjin, Jining, Handan, Chongqing, Suzhou, Shijiazhuang and Wuhan were the ten cities with greatest CO2 emissions in 2005, with total CO2 emissions of 205, 184, 145, 126, 116, 103, 96, 93, 90 and 81 Mt, respectively. These cities were either megacities or those dominated by coal, iron or steel production. However, the three cities with the highest CO2 emissions per GDP and CO2 emissions per capita were Jiayuguan, Wuhai and Shizuishan, which were dominated by industry, small- or medium-sized, and exhibited a high demand for heat and cooling. Cluster analysis revealed that industrial energy consumption was the dominant emission source for most cities, except Haikou and Lhasa, for which indirect CO2 emissions were dominant. This study will greatly contribute to the city level CO2 emission inventory and research on China.

In China, rapid development of electric vehicles resulted in large consumption of lead and lead products such as lead acid batteries (LABs). Recycling LABs is one option to mitigate natural resource depletion and corresponding environmental issues. However, few studies have been conducted to measure the operation of LABs recycling industry. Consequently, it is necessary to initiate such a study so that key barriers on promoting this industry can be identified. Under such a circumstance, this study proposes an emergy-based evaluation framework to evaluate one LABs recycling firm in Yunnan so that the emissions’ impact on human health and ecosystem from this firm can be quantified. A set of emergy-based indicators are established to evaluate the sustainability of this recycling firm. The results show that the investigated system had a higher emergy efficiency compared with that primary ore exploitation system. However, the extremely low values of emergy indicators indicate that this recycling system could not achieve sustainable development goals due to its heavy dependence on nonrenewable resources. Based upon such results and local realities, policy suggestions are raised in order to improve the overall sustainability of such a recycling system.

With fast development and urbanization, Chinese cities are facing several challenges including issues of environmental pollution, climate change, resource depletion and landfills shortage. Waste recycling is one effective way to respond these challenges. Under such a situation, this paper aims to evaluate energy saving and carbon reduction potential of recycling wastes by taking Shanghai, the biggest city in China, as a case study. Results show that 8.7 Mt standard coal (tce) and 16.81 Mt CO2 could be reduced under current recycling system in Shanghai. And recycling of waste steel and nonferrous metals were the two dominant contributors, accounting for about 44% and 42% of energy saving, and 60% and 33% of CO2 reduction, respectively. If the recycling rates of main recyclable wastes were improved to 100%, additional 6.44 Mt energy and 10.02 Mt CO2 could be further saved, mainly from recycling waste glass, waste plastic and waste metals. Adoption of RPF (Refuse Plastic & paper Fuel) could further contribute to 1.24 Mt energy saving and 2.67 Mt CO2 reduction. Finally, policy implications on establishing a mature recycling system and promoting RPF technologies are discussed, in which the potential on reducing total energy consumption and CO2 emission of Shanghai can reach 6.6% and 4.9%, respectively.

Many industrial parks are implementing industrial symbiosis in order to move toward eco-industrial parks. Research methods on industrial symbiosis expand from focusing on material flows and economic benefits to addressing on social aspects since collaboration among different firms can determine the efficiency of industrial symbiosis. Under such a circumstance, this study focuses on investigating industrial symbiosis relationships among tenant firms within one mining industrial park. Social network analysis (SNA) method was selected for analyzing the characteristics, power quantification and structure of the industrial symbiosis network by taking Gujiao mining industrial park as a case study. Results show that industrial symbiosis is still in its infancy in Gujiao industrial park and should be further optimized. Those anchor firms have less influence on industrial symbiosis and should be encouraged to actively involve in industrial symbiosis. Finally, policy recommendations are proposed by considering the local realities, including the establishment of an information platform, the use of economic instruments, necessary research and development efforts and broad public participation.

As a means of converting waste to energy, improvement of energy recovery efficiency from municipal solid waste (MSW) has taken on great importance and necessity. Previous studies have focused on the waste-to-energy potential from the viewpoints of technology, such as waste power generation (WPG); however, there is large room for improvement in WPG efficiency. Moreover, with reduction in population in some developed countries, the potential for further improvement of energy recovery from waste needs to be investigated, considering both geographical characteristics and future trends. To fill this research gap, this study proposes four efficient MSW management options through integrating MSW management and an urban symbiosis network. The Tokyo Metropolis, Japan, was selected as a case study, and the costs and benefits, effects of greenhouse gas (GHG) emission reduction, and energy recovery efficiency of each option were quantitatively analyzed. The results showed that Option 4 (urban symbiosis without source separation) has the highest energy recovery efficiency (65.95%), followed by Option 3 (urban symbiosis with source separation) and Option 2 (MSW centralized treatment) in 2030. Compared with Option 1 (business as usual), Option 3 will slightly increase the total cost, while Option 4 is the most profitable option, and the benefit will rise to 1.81 × 1010 JPY in 2030. Reduction of greenhouse gas (GHG) emissions by 2030 will be greatest with Option 3, which will eliminate 9.44 × 105 tonnes of CO2e emissions. Also by 2030, Option 4 and Option 2 will reduce the CO2e emissions by 6.58 × 105 tonnes and 2.27 × 105 tonnes, respectively. To promote the transition to a low carbon city, Tokyo must improve the energy recovery efficiency of MSW and use more renewable and recycled energy resources to substitute for fossil fuels. This study provides a practical guide for establishing a more efficient MSW management system toward the goal of a low carbon society.
