Electrical and electronics goods waste management and optimal warehouse location selection in Turkey

The amount of electronic waste is increasing gradually with the rapid and unconscious consumption of technological products today in Turkey. Within the scope of this study, the current situation of electrical and electronic goods in Turkey has been addressed. The registered collection rate of e-waste formed in our country is low. The main reason for the low collection rates is the unregistered and uncontrolled collection of e-waste. These wastes need to be recovered into the economy. Without a suitable collection structure, it is difficult to recover the resulting electronic waste. In this study, electronic waste (e-waste) that is not collected properly and inconsistently occurred is addressed. It is aimed to establish suitable warehouse locations in the districts close to the organized industrial zones covering certain provinces with developed electronic waste applications and industries in Turkey. There are 28 demand points in the study. To provide the most appropriate service to these demand points, the p-median problem was applied as a location-allocation model. The IBM OPL CPLEX program was used to determine the selection and number of warehouse locations to be opened. As a result of the optimization, suitable warehouse locations to be opened have been decided. It was decided that the optimal number of warehouses was 5. It is difficult for society to leave their wastes from their homes to places where warehouses are planned to be established. It is planned to create waste collection boxes in central places so that all provinces will receive service. The waste collection boxes formed can receive services from the opened warehouse locations.
