The application of the analytic network process to the assessment of best available techniques

The European Integrated Pollution Prevention and Control Bureau produces reference documents on Best Available Techniques, called BREFs. These documents give technical and descriptive information about the installations that represent a significant pollution potential in Europe. However, they do not provide an assessment of the Best Available Techniques, which is a decision to be made by the competent environmental authority. The present work proposes a decision-making process for assessing Best Available Techniques based on the Analytic Network Process. Seven evaluation criteria, grouped into three clusters, have been proposed. The process is applied to a case study and the results are described and analyzed. As a main conclusion, this paper describes a robust and scientific method for a better implementation of the Integrated Pollution Prevention and Control approach.

► BREFs documents do not provide an assessment of the Best Available Techniques.
► The evaluation of BAT is a Multi-Criteria Decision-Making problem.
► We model this problem with the Analytic Network Process (ANP).
► This paper describes a scientific method for a better implementation of the IPPC approach.
