Furthermore, future research could improve the 
simulation model and adapt the model to take into 
consideration the number and location of 
decentralised facilities and the corresponding 
transport implications (i.e. transport time, cost and 
CO
2
 impact).  
4 CONCLUSION 
This paper presents a discrete-event simulation tool 
that practitioners may use to model a future reverse 
supply chain that does not exist and has limited 
historical data. Managers and practitioners can use 
the model proposed to measure the impact of changes 
in processes, routes and volumes in terms of 
throughput, capacity (number of batteries processes, 
tonnes of material recycled, remanufactured batteries, 
repurposed batteries) and sustainability impact of 
changes (economic savings, CO
2
 impact). The 
insights of the model and the valuable metrics in 
terms of capacity planning and economic and 
environmental metrics were considered valuable by 
the industry experts who participated in this study to 
assess what-if scenarios and make informed RSC 
design decisions.
