Abstract

Agricultural use is one of the best options for sewage sludge management, whenever sludgequality is suitable with respect to established law limits and if local situations (field availability,climate, specific constraints) are favourable. This practice is recognized to be the mosteconomical one and allows recovering nutrients and organic matter with benefits to crops andland.Beside general rules issued at European level (Directive 86/278/EEC) and transposed in Italywith D.Lgs. 99/1992, regional authorities can establish other restrictions to better protectenvironment, preserve population from nuisance and defend specific areas.Through GIS elaborations, we have analysed different scenarios, computing available land inApulia region with present and new revised constraints and evaluating sludge quantities to bepotentially recovered for land application in the light of current legislative limits, nitrogenrequirements by crops and cultivation cycles.This study has showed that available land can face the total sludge production in the area evenin the most conservative hypothesis. The used methodology represents a powerful tool to movethe focus of political decisions from general law constraints towards specific ones closely relatedto the environmental and agricultural context and to plan new investments to completely satisfysludge disposal needs.
