The growing awareness of the negative impact of the manufacturing industry on the balance of the natural environment is contributing to increased interest in ecological issues among scientific and business circles. A key issue is the search for tools that promote sustainable development, which assumes that social, economic, and environmental goals should be equally important, and that limiting oneself to one of these areas, or focusing on only one of them in the long term, is harmful to enterprises and the environment in which they operate.
Although the subject of business activity is not solving global environmental problems, managers are beginning to perceive issues related to ecology as an integral part of business strategy, which will enable them to develop a positive image and gain a competitive advantage. A way to link industrial development and environmental protection (while maintaining a balance between cost minimization and the efficient achievement of organizational goals) is to create a closed-loop supply chain system in enterprises. The growing importance of material flows from the customer to the producer poses a major challenge for management. Managers must consider not only the flow of materials towards the customer but also the flow in the opposite direction, keeping in mind the possibility of recovering value and/or disposing of the product in accordance with regulations and standards (Figure 1).
Taking into account the stream supplying production, derived from recovered raw materials, allows for closing the material cycle and obtaining a closed-loop supply chain. Activities involving the flow of goods from the customer to the enterprise, referred to as reverse logistics, differ significantly from activities related to the flow of goods to the customer (these differences are summarized in Table 1). Regardless of the nature of the industry, there are certain fundamental aspects that distinguish a closed-loop supply chain that must be kept in mind when designing the system, including:
-
the environment is the determinant for setting costs and services
-
a large number of material flows and connections between them makes it a highly complex system
-
there is great uncertainty of supply, both in terms of quantity, quality, structure, and time
-
supply (stock of used products) is not linked to demand (the producer’s needs/requirements)
-
there is a “funnel” structure – many suppliers, few recipients (in a reverse supply chain, the raw material is used products coming from the market, therefore there are many more sources of raw materials than in the case of traditional chains)
-
the market is difficult to identify
-
the basis for creating new markets can be legal requirements or social responsibility for the protection of the natural environment.
However, it is impossible to provide a single, universal algorithm for creating a properly functioning, profitable, and beneficial closed-loop supply chain. Closing the loop in many enterprises is carried out by trial and error.
