“…There were more than 40 million disabled and semi-disabled elderly people in China at the end of 2016 and 7% are cared for long term by their family. Those who need direct care also desperately require the involvement of medical services [ 3 , 4 ]. Compared with developed countries in Europe and the United States, China shows a unique ageing characteristic of getting old before getting rich, at a larger scale, at a faster speed and showing a heavier dependency burden etc.…”

Background This study aims to analyse the current demand by senior citizens in Lanzhou, China for a combination of medical and elderly care services and to identify the factors influencing their needs. Methods 7500 participants aged 60 or above living in Lanzhou, China, were recruited, a unified questionnaire concerning elderly people’s demand for a service combining medical and elderly care has been adopted to survey these subjects. The status quo of the demand of the service combining medical and elderly care and its influencing factors were analysed with the single-factor Chi-square test and multi-factor binomial logistic regression method. Results 3772 of 7320 older people have the demand for the service combining medical and elderly care, accounting for 53.15% of survey respondents. Many factors are in play, including gender, marital status, degree of education, occupation before retirement, number of children, monthly income, health self-assessment status, endowment insurance type, medical insurance type, current nursing arrangements, old-age demands, self-care ability and the knowledge of combining medical and elderly care and the willingness to pay for the combination of medical and elderly care have statistical significance (P < 0.05) with the elderly’s needs, different ages, living styles and the prevalence of chronic diseases, have no statistical significance (P > 0.05) with the elderly’s care needs in Lanzhou. The number of children, type of medical insurance and willingness to pay for the combination of medical treatment and nursing care are major influencing factors among the complex factors influencing the elderly’s demand for the proposed service. Conclusions The low knowledge rate and demand rate, the number of children, the type of medical insurance, and the willingness to pay for the medical-nursing combination service for the elderly in Lanzhou have a great impact on the elderly’s demand rate for combining medical and elderly care. Meanwhile, relevant government departments should focus more on the promotion of the endowment model of combining medical and elderly care and provide integrated medical care services by integrating multiple resources, and improving social security.

“…The Emergy analysis quantifies three footprints, namely, renewable natural resources (R), nonrenewable natural resources (N), and imported resources (F). These footprints lead to the quantification of Emergy yield ratio (EYR), environmental loading ratio (ELR), and the Emergy Sustainability Index (ESI), which are the indicators for assessing the sustainable development of a system. ,− The total Emergy depicts the wealth of the system. The EYR, estimated by dividing the total Emergy by the imported resources, describes the economic dependence of the process on imports.…”

The increasing trend of solvent usage by chemical industries has caused an upsurge in hazardous waste solvents and, consequently, increased their toxicity potential within the environment. The increase in overall carbon and ecological footprints due to conventional waste handling techniques such as incineration and onsite and offsite disposal can hardly be overstated. Even though solvent recovery methods present a better alternative to these techniques, analysis is generally centered on economics. This paper presents a framework that evaluates the economic and sustainability metrics of solvent recovery processes. In the first approach, standalone software (SimaPro) was used to evaluate the impact of the recovery process. The framework was extended by incorporating the economics, Sustainable Process Index (SPI), and Emergy metrics. Thus, solvent recovery challenges have been transformed into a multiobjective optimization problem that is solved through superstructure and mixed-integer nonlinear programming techniques. The applicability of the framework is illustrated by two comprehensive case studies with varying complexities, and the results are compared with conventional methods. The results indicate that about 76−85% of the ecological and energy burden can be prevented if solvent recovery is the preferred option to incineration.

“…Run-ping Wang and Xiang-min Rong used emergy analysis to study the input/output, work efficiency, and environmental load of the agro-ecosystem in Shanxi Province in 2005 [28]. Guo and Dong et al applied emergy synthesis and information entropy to estimate the urban ecosystem health of Taiyuan (the capital city in Shanxi) during the 2001-2017 period, providing insight into the policy implications [29]. Xiuli Liu and Pibin Guo et al took Shanxi Province as a case study and applied emergy analysis to build a multi-index sustainability evaluation system of a coal mining area in China during 2006-2015 [30].…”

Assessment of the Sustainability of the Resource-Based Province Shanxi, China Using Emergy Analysis

2022

According to the BP Statistical Yearbook of World Energy, China’s coal production and consumption have ranked first in the world in recent years. Shanxi, a central China province, plays an important role in China’s energy supply because of its large coal reserves, long mining history, and high output. The aim of this study was to evaluate the sustainability of the eco-economic system in Shanxi Province, a typical resource-based region. Through emergy analysis, this study quantified the sustainable development of the eco-economic system in Shanxi Province from 2013 to 2020 from five dimensions: basic emergy quantity, social subsystem, economic subsystem, environmental subsystem, and capacity for sustainable development. The results show that Shanxi Province has made great progress in recent years in terms of the emergy value of renewable resources, per capita emergy consumption, and electricity emergy ratio, but the proportion of nonrenewable emergy is still large, the intensity of emergy is high, and the exchange rate of emergy is low. Lastly, the sustainable development indicators ESI and EISD reflect that Shanxi Province is gradually improving the utilization efficiency of resources, and Shanxi Province has achieved certain results after experiencing transition pains. This study, combined with the actual situation of Shanxi Province and the problems found, puts forward corresponding countermeasures. The analysis method used in this study provides a theoretical basis for the scientific evaluation of the sustainable development of a resource-based region, and the research results have profound practical significance for improving the quality of Shanxi’s economic development and helping Shanxi’s economic transformation.
