Reverse logistics is becoming more important in overall industry area owing to the environmental and economic factors. Planning and building a reasonable reverse logistics system could bring more profit, customer satisfaction and a nice social picture for companies. The energy-intensive industry is an important part of Chinas industry. We try to construct a reverse logistics system of the energy-intensive industries with the perspective of circular economy in this paper, which aims to reduce resources consumption and environmental pollution, and to promote economical, social and ecological environment development.

The study is devoted to solving the problem of forming reverse material flows with the use of circular economy processes, which will achieve maximum efficiency of the logistics system.The existing linear model of the economy is not environmentally oriented, as it constantly requires the involvement of additional primary resources, which, passing through the man-made system, produce a large amount of waste. The concept of circular economy is based on the principles and goals of the concept of sustainable development and emphasizes the need to close logistics systems, the creation of logistics systems with feedback. The tool for the implementation of the concept are closed logistics chains, which include direct and reverse material flows.Participants and the processes used in the circular economy model proposed by the Ellen McArthur Foundation were used to create a model of a feedback logistics system that includes complete closed logistics chains. According to this model, the main participants in closed chains are: resource provider, parts manufacturer, product manufacturer, service provider, consumer/user, collection center), repair center, sort center, utilization center.Within a complete closed supply chain, the direct chain starts with the natural environment and the supplier of resources and ends with the consumer/user of the product, the reverse chain begins with the consumer/user of the product and ends with the recycling center and the natural environment.Among the processes of the circular economy to highlight the processes related to reverse logistics and involved in the organization of reverse flows to create feedback in a closed logistics chain: recover, recycle, refurbish, remanufacture, repurpose, repair, reuse. These processes, which can be called circular, create logistics loops between the participants in the logistics chain, providing feedback in closed logistics chains.The article presents a graphical model of the logistics system with feedback using circular processes; created an economic-mathematical model of the logistics system with feedback.Keywords: circular process; closed logistics chain; logistics loop; reverse material flow.

Proposed Model

Today, reverse logistics (RL) is one of the main activities of supply chain management that covers all physical activities associated with return products (such as collection, recovery, recycling and destruction). In this regard, the designing and proper implementation of RL, in addition to increasing the level of customer satisfaction, reduces inventory and transportation costs. In this paper, in order to minimize the costs associated with fixed costs, material flow costs, and the costs of building potential centres, a complex integer linear programming model for an integrated direct logistics and RL network design is presented. Due to the outbreak of the ongoing global coronavirus pandemic (COVID-19) at the beginning of 2020 and the consequent increase in medical waste, the need for an inverse logistics system to manage waste is strongly felt. Also, due to the worldwide vaccination in the near future, this waste will increase even more and careful management must be done in this regard. For this purpose, the proposed RL model in the field of COVID-19 waste management and especially vaccine waste has been designed. The network consists of three parts – factory, consumers’ and recycling centres – each of which has different sub-parts. Finally, the proposed model is solved using the cuckoo optimization algorithm, which is one of the newest and most powerful meta-heuristic algorithms, and the computational results are presented along with its sensitivity analysis.

High growth rates of natural resources consumption in recent years, pollution of the environment contribute to the development of theories regarding the future provision of natural resources on the Earth. Thepurpose of the article is to study the concept of sustainable development and the need for its introductioninto economic activity, definition of ideas influencing the modern concept of the circular economy. The concept of stable development and circular economy is analyzed, common features and differences are defined.It has been established that the circular economy is a prerequisite and driver of the fourth industrial revolution. The basis of the circular economy are closed supply chains. They combine the usual processes of adirect supply chain with reverse logistics processes, ranging from product recovery, disassembly and reuseof individual parts.

Development Goals

The importance of reverse logistics and product recovery is evident in various industries as well as in current UNESCO sustainable development goals. This includes plastics and recycling with the former “contributed” significantly towards environmental issues and the latter being one of the primary solutions. The motivations of its implementation are generally divided into legal, economic, and socio-environmental factors. One of the crucial components of plastics recycling and a reverse logistics system is product return channels. The success of other components especially the recovery operations depends on the effectiveness of the return channels. Although numerous investigations on product return channels have been carried out, research on some critical aspects remains wanting. This study presents a review that highlights this deficiency, depicts relevant research development on product return channels, decision-making issues, and direction for future research. At the end of the study, the authors propose a new closed-loop logistics network and future research framework propositions.
