To date there is no regulation in EU waste legislation to nanomaterials. The European Sewage Sludge Directive (86/278) aims to control the use of sewage sludge in agriculture so that harmful effects on soil, vegetation, animals and man are prevented, while a proper use of sewage sludge wil be promoted. These regulations and strict requirements on the basis of water law and chemicals law have meant that the pollutant content in municipal sewage sludge is decreased in recent years in some cases by more than 90 percent.
