Recycling economy development model and macroeconomic policy

To develop circular economy is an important way to implement sustainable development strategies. This paper discusses the theoretical origin of the circular economy, and clarifies the mechanism development of circular economy. Combined with the status quo of China＇s economic development, it analyzed the facing problems in the development of circular economy. Our country has carried on the positive exploration and practice in the use of the concept of circular economy to promote sustainable development, and China＇s circular economy is transferred from the start-up phase to promote the establishment of policy mechanisms. Circular economy strategy will also begin to implement in some of China＇s mega-cities. Faced with the arrival of the circular economy, we should look to a higher level up to explore how people should take effective measures to turn challenges into opportunities.

Promoting sustainable consumption and circular economy:the intention of Vietnamese youth consumers to purchase products made from recycled plastics

Recycling is viewed as a key component in a circular economy and serves as an ideal solution for promoting sustainability.During the global plastic crisis,plastic recycling practices have been adopted worldwide,leading to the production of various products made from recycled plastics(PRP).Nevertheless,a gap persists between consumption and demand for such products,which is primarily attributed to a lack of comprehension from the consumer perspective.Given the pivotal role consumers play in the adoption of these products,this study explores consumers’intentions to purchase PRP.This is particularly significant in Vietnam,which is an emerging economy aspiring to achieve the objectives of a circular economy and sustainable development.Utilizing an integrated cognitive-emotional framework comprising the Valence Theory and the Norm Activation Model,data from 564 Vietnamese students were gathered and analyzed using structural equation modeling.The results show that awareness of consequences is a major driver of consumer purchase intentions,followed by perceived ease of application and monetary incentives.The results also indicate that health concerns have the strongest effect on purchase intention and in the negative side,meaning that the health-related risk is the primary concern for consumers during the decision-making process.This research holds substantial value for academics and managers,as it aids in the theoretical exploration and the formulation of strategies to improve consumer acceptance of PRP.

Economy Analysis of a Recycle Model of End-of-Life Vehicle

In order to evaluate recycle economy of end-of-life vehicles quantitatively,an economy model based on a recycle model of end-of-life vehicles and recycle cost analysis. With a practical example of recycling engines of end-of-life vehicles ,the validity of the recycle economy model and good recycle economy of the end-of-life vehicle engine were justified. It is concluded that ① remanufacture-ability of the part or component of the vehicles; ② the organization and management level of a recycle corporation; ③ policies and regulations of the government are crucial factors to raise the recycle economy of the end-of-life vehicle.

Development of Agricultural Recycle Economy in Arid Areas of Hexi Corridor——A Case Study of Zhangye City, China

Taking Zhangye City as an example, the thesis analyzes the restricted factors of resources and environment confronted by the agriculture in arid area of Hexi Corridor: the first is the agricultural natural resources. The area of cultivated land decreases year by year, and there are sharp decrease of biological diversity as well as the shortage and waste of water resources; the second is the ecological environment. There are critical soil erosion, frequent natural disaster and outstanding agricultural area source pollution; the third is the rural economy. The agricultural structure still can not meet the need of agricultural development in recent years, and the proportion of agricultural product processing is low. It points out that implementation of agricultural recycle economy is the necessary choice of the agricultural development in Zhangye City. Developing recycle economy is conducive to improving ecological environment and realizing agricultural sustainable development; developing recycle economy can solve the agricultural area source pollution to much extent and protect rural environment; developing recycle economy is conducive to adjusting rural industrial structure, increasing job opportunities and increasing farmers' income; developing recycle economy is conducive to elevating the international competitiveness of agricultural products. The thesis also has put forward the countermeasures of developing agricultural recycle economy in Zhangye City as follows: firstly, fostering the ambience of the development of agricultural recycle economy; secondly, forming the incentive mechanism of development of agricultural recycle economy; thirdly, broadening the investment channel of development of agricultural recycle economy; fourthly, perfecting socialized service system of agricultural recycle economy.

Recycling of solid-state batteries—challenge and opportunity for a circular economy?

The tremendous efforts made in the research field of solid-state Li-ion batteries have led to considerable advancement of this technology and the first market-ready systems can be expected in the near future.The research community is currently investigating different solid-state electrolyte classes(e.g.oxides,sulfides,halides and polymers)with a focus on further optimizing the synthesis and electrochemical performance.However,so far,the development of sustainable recycling strategies allowing for an efficient backflow of critical elements contained in these batteries into the economic cycle and thus a transition from a linear to a circular economy lags behind.In this contribution,resource aspects with respect to the chemical value of crucial materials,which are used for the synthesis of solid-state electrolytes are being discussed.Furthermore,an overview of possible approaches in relation to their challenges and opportunities for the recycling of solid-state batteries with respect to different solid-state electrolyte classes by means of pyrometallurgy,hydrometallurgy and direct recycling/dissolution-based separation processes is given.Based on these considerations and with reference to previous research,it will be shown that different solid-state electrolytes will require individually adapted recycling processes to be suitably designed for a circular economy and that further improvements and investigations will be required.

Enhancing the Decomposition of Paper Cups Using Galleria Mellonella and Eisenia Fetida

The composition of paper cups creates a challenge for the recycling industry,as the paperboard–plastic film composite is hard to separate.Therefore,paper cups are sent to landfills or waste incinerators.This study explores the combined use of red worms(Eisenia fetida)and Greater wax moth(Galleria mellonella)in the biodegradation of paper cups.The study investigates the conditions and combinations that promote using Eisenia fetida and Galleria mellonella for degrading paper cups.The study considered the influence of environmental temperature,the presence of food waste,varying the number of Eisenia fetida worms,and the presence of a Galleria mellonella growth-slowing agent on the degradation process.To achieve the study objectives,the study followed a quantitative approach.The study monitored the degradation of paper cup cuts that were placed in jars containing different combinations of Eisenia fetida worms,Galleria mellonella larvae,food waste,bedding material,and Galleria mellonella growth-slowing agents.The study found that the best operating temperature is 30oC.The study found that using food waste improves the performance of Eisenia fetida worms and Galleria mellonella larvae significantly.The study found that adding a Galleria mellonella growth-slowing agent slightly enhances the degradation of the paper cup.Finally,a numerical model was obtained to simulate the paper cup degradation efficiency.
