Closed‐loop supply chains in process industries: An empirical study of producer re‐use issues

Abstract

Closed-loop supply chain research has primarily focused on discrete industries, leaving important issues involving waste disposal and re-use in process industries unaddressed. This exploratory study investigates re-use issues and practices related to process industry firms-from the producer's perspective-with the objective of identifying important issues that need further research in the field. Site visits were conducted to identify and clarify re-use issues unique to process industry firms for the purpose of developing a mail survey instrument. The mail survey provided detailed information about the sources of returned product and materials and the subsequent re-use decisions made by 141 different manufacturing facilities in a wide variety of process industries including chemicals, food, rubber, and plastics. Results indicate that process industry firms are quite diverse, that some common beliefs about re-use in process industry firms do not apply to all process types in these industries, and that research efforts are needed in the areas of network design and product acquisition; inventory; production planning and control; and scheduling. The paper concludes by identifying specific research questions important to re-use in process industry environments. #

Green Supply Chain Collaboration for Fashionable Consumer Electronics Products under Third-Party Power Intervention—A Resource Dependence Perspective

“…As claimed in research of power theory, power is defined as the ability to influence and control goals, decisions, and behavior of people and organizations either coercively or non-coercively [22,[42][43][44][45]. In this work, two primary power sources underlying TPPI are considered: (1) political power which is characterized by government intervention via either regulatory or economic measures [46,47]; and (2) social power which is characterized by challenges posed by non-profit organizations (e.g., Greenpeace International and local green organizations) [48][49][50].…”

“…Despite remarkable advances made by pioneering green supply chain management research [17,[19][20][21][22][23][24], issues related to the interplays and relational governance as green supply chain members move toward a long-term collaborative green supply chain under TPPI remain challenging [18,25,26]. As argued in Sarkis et al [18], the interdependency of green supply chain members and their effectiveness determine the success of green supply chain management from a resource dependence perspective; however, they have not yet been satisfactorily addressed in literature.…”

Reverse Logistics Management and Enviromental Sustainability Drive in Nigeria (Study of the Food and Drink Industries)

“…Reverse (logistics management) distribution is the movement of broken, unwanted or excess products returned by the consumer or resellers- Kotler and Armstrong [2006: 379], French, and LaForge [2006] and Fleischmann, Galbreth and Tagaras (2010). It is also a process of reclaiming, recyclable and reusable materials, returns and reworks from the point of consumption or use for repair, remanufacturing or disposal -Berkowitz, Kerin, Hartley and Rudelius (2000: 460).…”

Does Centralization Lead to higher Efficiency? – An Industry-specific Analysis of Purchasing Functions

“…Despite the diversity between process industry segments (French & LaForge, 2006), they have several characteristics in common that distinguish them from discrete manufacturing industries (Dennis & Meredith, 2000a). During their analysis of 19 different process industry sites, Dennis and Meredith (2000b) show that, on average, only a few inputs are processed per unit of product output.…”

“…This supports the general assumption of manageable bills of material in process industries. Since material costs often amount up to 80 percent of the overall product costs (Rice & Norback, 1987;French & LaForge, 2006), process indus-tries lay more emphasis on factors such as cost and raw material quality control than on product redesign or manufacturing innovation. The low R&D intensities, especially in Food & Beverage industries (Lager, 2002), indicate that sudden changes or modifications of the purchasing situation are exceptions.…”
