The linear economic model of extraction, production, consumption and disposal brought, respectively, scarcity of natural resources and excessive waste generation. In Brazil, 32% of municipal solid waste is recyclable / dry material (ABRELPE, 2018) and among these 70% is packaging (LEITE, 2018). Using waste as inputs for the same chain is a premise of Closed Loop Supply Chains - CLSC. Guide and Van Wassenhove (2009) define CLSC as the design, control and operation of a system to maximize value creation over the entire life cycle of a product, with dynamic value recovery of different types and volumes of products. returns over time. Most of the discussion on CLSC are focused on recovering the financial value of high value-added end-of-life products such as the automobile and electronics industry. There is little research focused on low value-added products, leaving doubts as to whether CLSC concepts, expectations and good practices also apply in the context of low value-added products.
The overall objective of this research is to delve into already closed loop supply chains of low value-added products to see what factors enabled them to close. The methodology adopted was multiple case studies, exploring three CLSC of glass and plastic packaging, using as a theoretical framework the framework of Quarigasi (2010), and of the three CLSC feasibility processes of Guide and Van Wassenhove (2009).
The results suggest that CLSC have some different configurations in the context of low value added products. Highlighting the important role that waste management legislation assumes in the case studied the PNRS, being a relevant factor for both viability and expansion of closure. New and relevant players in the CLSC viability processes have been identified, such as the government in return management, integrated communication to precede operational remanufacturing problems, and the sustainability factor as a driver of the remanufactured products market.
