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.

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.
