The industrial and technological advances of the last two centuries have created a significant hazardous waste management
problem in the developed world. Hazardous waste management involves the collection, transportation, treatment and
disposal of hazardous wastes. In this paper a new multiobjective location-routing model is proposed. Our model also
includes some constraints, which were observed in the literature but were not incorporated into the previous models.
In addition to these constraints, our model also has some additional constraints that we propose. The aim of the
proposed model is to answer the following questions: where to open treatment centers with which technologies,
where to open disposal centers, how to route different types of hazardous waste to which of the compatible treatment
technologies, and how to route waste residues to disposal centers. The model has two objectives of minimizing
total cost and minimizing transportation risk. A large scale implementation of the model in the Central Anatolian
Region of Turkey is presented.
