Overview of Theory and Model of Tropical Agricultural Circular Economy in Hainan Province

This paper gives a general overview of rationale of tropical agricultural circular economy.On the basis of ecological economic theory,circular economy is a new model of economic development which aims at realizing reducing of resources use,reuse of products and recycling of wastes,conforming to the principle of 4R.It is to make economic system melt into the process of cycle of material of natural ecological system harmoniously.This paper introduces the advantages of developing tropical agriculture in Hainan Province,the main problems existing in the development and two main models of sustainable tropical agricultural development in Hainan Province at present.9 typical models of tropical agricultural circular economy in Hainan Province are listed in particular,including compound ecological project of forestry and animal husbandry,three-dimensional planting model of plantation,multilayered structure of eucalyptuses,sustainable agricultural model of sightseeing,the model of using animal manure,precision tropical agricultural model,clean production model of tropical agriculture,deep processing model of tropical agricultural products,and the model of ecological agricultural industrialization.Corresponding countermeasures and suggestions are put forward to promote development of tropical agricultural circular economy in Hainan Province as follows:take actions that suit local circumstances,exert advantage and exploit potential;give full play to advantage of integration of production,teaching and research,and promote agriculture by applying scientific and technological advances;the whole staff participate and strengthen construction of soft environment and hard environment.

A Study of the Industrial Circular Economy Using an Essence Analysis Model

The concept of a circular economy can be applied to different business fields.The development of the existing industrial cycles with an overemphasis on economic development and the twisting concept of a circular economy,has limited any substantial contribution of the circular economy to environmental resources.In some cases,resources are even being consumed to create resource recycling.This puts a greater burden on the environment.To gain an understanding of the actual value of a circular economy to the environment and resources,an“Essence Analysis Model”has been used in this study.This combines sustainable development issues in a multi-faceted and multi-leveled analysis of the industrial circular economy model to guide its development more directly towards fundamentals.An analysis of the results of the“Essence Analysis Model”was used to find and change the original strategy,and develop a means of improving the circular economy model.The results of the study make an essential contribution to the sustainable development of environmental resources and the reduction of greenhouse gas emission.

How Has the Wine Sector Incorporated the Premises of Circular Economy?

Much has been done in the wine production sector to promote sustainable development.Given its relevance in the economy and in society,it is fundamental to align its activities with the optimal use of resources and the regeneration and restoration of the natural system in agreement with the premises set by the Circular Economy(CE).The main interest of this work was,through a systematic literature review,to identify in the revised studies how the wine sector has incorporated the premises of CE in its activities.Six topics define the concerns addressed:water,solid waste,energy,chemical use,land use and ecosystems,in different parts of the chain:viticulture,winemaking and distribution.From the evaluation of 41 selected empirical studies,no clear definition regarding CE was found;however,the detailed analysis reveals aspects which incorporate CE practices such as the reduction of waste disposal by its treatment and recovery,the best use of resources at all stages of the process chain and the need to rethink and redesign current practices.The specific subjects identified were waste recovery,alternative energy sources such as biofuels production and water quality improvement.Land use,ecosystem impacts,and use of agrochemicals were not considered.

Construction of New Value Chain Management and Various BOMs for Research Project of SDGs Food Loss Reduction:Case Studies on Circular Economy Sweets Product Planning,Sales Event Holding,and Questionnaire Surveys

Regarding the social problem of food loss in Japan,about 10%-20%of agricultural products(e.g.vegetables and fruits)are seen as“non-standardized foods”or“surplus foods”by the Agricultural Cooperative Association.Those foods are then discarded.The Tamaki Laboratory of the School of Business,Aoyama Gakuin University is promoting the“SDGs Food Loss Regeneration Project”through industry and academic collaboration—as a research study—to solve this social problem.Therefore,the purpose of this research is the following three subjects:(1)Indicate the design of VCM(value chain management).VCM corresponds to the planning,manufacturing,and sales meetings of“SDGs Moist Vegetable Cake”,and the roles of stakeholders engaged in each area of VCM.(2)Design various BOMs(bill of materials)corresponding to the VCM.Describe how to use BOM and the significance of using each BOM in cooperation.(3)In order to verify the effectiveness of the“SDGs Food Loss Regeneration Project”with“SDGs Moist Vegetable Cake”,conduct and analyze questionnaire surveys and consider the results.

Waste Recovery and Sustainable Development. A Case Study of Material Development from Used Tires in Africa

This paper outlines a mechanical transformation process for rubber recycling, demonstrating the development of a new material from used tires. With the crumbs obtained using a crusher-compactor, a novel material for the manufacture of O-rings has been developed, with properties close to those found on the market. The process includes an experimental methodology of a sulfur vulcanization system choice and the quantification of ingredients, as well as the experimental determination of cure parameters. Mechanical tests on the samples completed the work by providing the mechanical characteristics of both unaged and aged (thermo-oxidative ageing) novel material. This process has a high potential for sustainable development and industrialization, making it a valuable contribution to the recycling of rubber in African developing countries.

A Talk on the Essence of Circular Cities

Research on the essence of policy implementation is the basis for finding solutions.A circular city is founded on the concept of a circular economy,extending from the recycling of single substances to regional resource recycling development.Given limited energy and resource conditions,the emphasis lies in considering right from that source that at the end of a product’s service life substances can continue to enter their cycle of reuse and re-utilization.Meanwhile,residual substances can return to the industry and organisms as basic nutrients.The development of circular cities has to be multi-faceted synergetic promotion.Otherwise,it will be deviating from the meaning of the circular essence.In this study,the sustainable development of environment,economy,society and governance aspects were adopted as the starting point for exploring the connotation of the promotion of circular cites.The semi-structured expert interview was adopted as the research method.The pyramid principle was employed to carry out logical inference.The Fishbone Diagram was used to carry out time series analysis in order to ensure relevant requirements do not deviate from the mindset of circular essence during circular city planning.Finally,the 13 circular city planning solutions proposed in the research results and contribution can be specifically provided to agencies engaged in circular city planning and governance.
