Abstract
When aiming for a more sustainable world, enterprises such as aircraft and automobile industries are highly interested in lightweight components and solutions. Among these solutions are aluminum wrought alloys that offer high potentials for dramatic weight reduction of structural parts. Nevertheless, the production of virgin aluminum is highly energy consuming. Major energy reduction may be achieved if recycled aluminum is used. The aim of the European project SuPLight is to address new industrial models for sustainable lightweight solutions - with recycling in high-end structural components based on wrought alloys. This article addresses the issue of designing the reverse logistics network assuring the needed volume of recycled aluminum for the production of L-shaped front lower control arms for personal cars. It details the developed method and demonstrator for designing a reverse logistics network based on a life cycle assessment.
Highlights
Until recently, reverse logistics (RL) was not given a great deal of attention in organizations
Reverse logistics is of high importance for aluminum-based products, since the production of virgin aluminum is highly energy consuming [6]
According to the recent literature review in [17], the only objectives considered in reverse logistics or forward/ reverse network design are cost, profit, responsiveness, source balance, Figure 1 Front lower control arm (FLCA) [14]
Summary
Reverse logistics (RL) was not given a great deal of attention in organizations. Cardoso et al [27] proposed a mixed-integer linear programming model for supply chain planning including reverse logistics activities They consider the expected net present value (ENPV) as the decision criterion. In this case study and research work, the environmental impact of the network is an important design factor; it should be considered as a main decision criterion in the design of reverse logistics network. This means considering the environmental impact of transportation activities, and the remanufacturing and recycling activities
