In this work we apply MCDM tools for the restoration of the phosphorous ponds of Huelva estuary, where the two mainly phosphoric acid production plants in Spain are located, which apply the wet production route through digestion of the phosphate rock by sulphuric acid.
For this, we take into account economic, social, environmental and radiological aspects. We consider a multi-attribute utility model that accounts for imprecision concerning the remediation alternative impacts and uncertainty about the DMs preferences by means of a linguistic term scale, ordinal information about the relative importance of criteria and fuzzy and interval values.
Different remediation alternatives are analysed, such as the remediation in situ, using the conditioning of the pounds and vegetation cover and other alternatives, the removal of this waste to landfills of conventional waste or its reuse in other applications as material to amend soils, construction, roads…
