Location of specific risk material incinerator plants in Andalucia using a multicriteria approach

We analyse the problem of choosing the location of incineration plants for the disposal of solid animal waste from preestablished sites in Andalucia. The waste collected by lorries from slaughterhouses should arrive at such plants once a week. Given the nature of the problem, we used multicriteria techniques for its solution. On the one hand, we have to take into account economic criteria such as start-up, maintenance, and transport costs; and on the other, social issues such as social rejection by towns on the lorry route, maximum risk as an equity criterion, and the negative implications for towns close to the plant.
