Additionally, it should be elaborated if an increase in the amount of sewage sludge has to be expected and which reasons are indicated. Because of the introduction of the Urban Wastewater Treatment Directive 2006 as amended By-Law in Turkey, experts estimate an enormous growth of sewage sludge to more than 1 million tons DS per year in 2020 (ENVEST planners, 2005).en1758-208320111-2116128Disposal routesMunicipal sewage sludgeSewage sludge production in Europe and TurkeySludge disposalSludge increaseJournal Article10.1504/IJGW.2011.038374Journal Article
