Category: Resource Management · Effect: Strong effect · Year: 2020
Strategic placement of collection and processing facilities for end-of-life lithium-ion batteries significantly impacts the economic viability and efficiency of their recycling.
Design Takeaway
When designing systems for product end-of-life management, conduct thorough network analysis to determine optimal facility locations and capacities to minimize costs and maximize resource recovery.
Why It Matters
As the volume of discarded lithium-ion batteries grows, establishing efficient reverse logistics is crucial for resource recovery and waste reduction. Designing a network that considers factors like transportation costs, facility capacity, and geographical distribution can lead to substantial savings and improved environmental outcomes.
Key Finding
