Sewage sludge management is a serious and difficult to problem worldwide. Traditionally, sludge is landfilled, incinerated or landspread, however, is true that the major part is still landfilled, a practice that is far from being a sustainable management practice. The problems associated to health effects concern the untreated sludge as well as its disposal and treatment methods and sewage sludge became an issue of strong conflict within the scientific society as well as between governmental policies and citizens organizations. In the same time, sludge is rich in nutrients such as nitrogen and phosphorous and contains valuable organic matter, useful when soils are depleted or subject to erosion. The development of sustainable sludge management depends largely on the possibilities to improve the quality of the sludge itself and increase confidence in sludge quality which highlights the need for prevention of pollution of the wastewater at source. In the present Chapter the three main management options are presented, namely, agricultural land application, incineration and landfilling.
