Natürliche Ressourcen werden zunehmend knapper, unter anderem da weltweit derzeit deutlich mehr natürliche Rohstoffe abgebaut und verarbeitet werden, als die Erde in diesem Zeitraum zur Verfügung stellen kann. Als Nettoimporteur von Rohstoffen ist die deutsche Wirtschaft insbesondere bei...

Natürliche Ressourcen werden zunehmend knapper, unter anderem da weltweit derzeit deutlich mehr natürliche Rohstoffe abgebaut und verarbeitet werden, als die Erde in diesem Zeitraum zur Verfügung stellen kann. Als Nettoimporteur von Rohstoffen ist die deutsche Wirtschaft insbesondere bei...

Der vorliegende Diskussionsbeitrag beschäftigt sich mit regulatorischen und politischen Ansätzen zur Verlängerung der Nutzungsdauer von Smartphones in Deutschland, anderen EU-Mitgliedsstaaten, den USA sowie auf EU-Ebene. Im Zuge eines steigenden Umwelt- und Nachhaltigkeitsbewusstseins rückt...

Im Zusammenhang mit der wachsenden Bedeutung des Themas Nachhaltigkeit rücken Refurbishment-Geschäftsmodelle auch für Smartphones verstärkt in das öffentliche Interesse. Zunächst ist festzuhalten, dass es sich beim Markt für Refurbished-Smartphones im Vergleich zum Markt für Neugeräte...

To find the manufacturer's optimal recycling mode under the dual factors of government subsidies and consumers’ low-carbon preference, we construct three game models by taking the wholesale price, retail price, recovery rate and carbon emission reduction level as the decision variables. Then,...

Motivated by interactions with a major player in the aerospace industry, we consider the relationship between a supplier of specialty material forgings and a buyer that manufactures airplane components by extensively machining down these forgings as per component design specifications. Due to...

In spite of raising awareness of the environmental impacts associated to the production and utilization of plastics, in many situations, the use of plastics is advantageous, and options are still unavailable or under development, representing an opportunity to develop more sustainable options,...

Remanufacturing reduces final wastes to sinks, extraction of virgin materials and pollution from production processes by reinstating products taken back by end-users to satisfy part of overall demand. Product returns are delayed and possibly limited in periods of fast growth and excessive in the...

Remanufacturing is an industrial process turning used products into a condition of like new or better. Remanufacturing is also one strategy that salvages the value put into products during manufacturing and thus reduces the environmental impact of products over the life-cycle. However, not many...

Remanufacturing has been receiving a growing attention in both academia and industry due to its economic and environmental benefits. This study investigates the effects of simultaneous remanufacturing, i.e., the effects of entrance of an actor to remanufacturing business when there is already...

Circular Economy (CE) aims to maintain the value of products, components, materials, and resources in the economy for as long as possible. Current end of life (EoL) product circularity decision-making methods are focused on technical and economic factors neglecting other crucial areas such as...

We study the competition between two remanufacturers in the acquisition of used products and the sales of remanufactured products. One firm has a market advantage; we consider two separate cases where either firm could have an acquisition advantage. The problem is formulated as a simultaneous...

Introducing proprietary parts to gain a competitive edge is a well-known, yet poorly understood strategy original equipment manufacturers (OEMs) adopt. In this paper, we consider an OEM which sells new products and competes with an independent remanufacturer (IR) selling remanufactured products....

Unlike consumer durable goods, high technology products have shorter life cycles. Many companies launch new items at a fast rate of innovation. As a result, the latest products often compete in the same market with earlier-generation products. In addition to brand-new products, used products...

With the fast development and frequent changes of the engineering products, natural resources are arbitrary exploited and the environment is used without repayment, which causes many problems of great magnitude such as zoology damaged all over the globe, resource waste and depletion,...

By definition, a remanufactured product must perform to the same (or higher) level as the original product, and must therefore be issued a warranty of the same (or longer) duration. However, many components of remanufactured products will have been subjected to regular stresses in their first...

This research deals with pricing decisions in a closed-loop supply chain constituted by a manufacturer, two retailers and the end consumers. The manufacturer is assumed to be the Stackelberg leader while one of the retailers engages in collecting activities. In this paper, we consider collecting...
