This paper presents two methodologies to evaluate and select Best Available Techniques (BAT): a methodology based on equal weighting of criteria and the Analytic Hierarchy Process (AHP). The aim of this work is the identification of the most sustainable BATs for the ceramic industry. To target these, 9 BAT options used in 13 alternative configurations of the ceramic tile manufacturing process have been considered and assessed on sustainability using relevant environmental, economic, technical and social indicators. After that, two multicriteria methodologies are applied. The first one combines screening techniques, as the economic feasibility, with graphical comparisons. The second one is the AHP method, which is based on the preferences of a decision maker to prioritize criteria as well as technological alternatives. This method is widely used in multicriteria decision problems because it is a structured tool that simplifies complex decisions. Applying both methodologies, the most sustainable scenario for the ceramic tiles industry combines heat recovery from flue gas with techniques to reduce noise or diffuse dust emissions and/or the flue gas depuration with CaCO3 and/or Ca(OH)2.
