Abstract
Today, the amount of the sewage sludge coming from domestic and industrial waste water which appear due to population increase, industrialization and urban growth has reached a level that is threatening human health and the environment. It is of crucial importance that the sewage sludge is removed with environmental-friendly methods for the protection of the environment. In this scope, the waste water sewage sludge is used in agricultural areas, forest areas, parks-gardens, recreational grounds, recreation of areas, urban landscaping as well as in arboriculture, and in growing ornamental plants as organic fertilizers, germination media and growth media. In ornamental plant growth, which has an economical value, the use of sewage sludge helps to decrease the high production costs and thus contributes to the economy of the country creating a new alternative field in removing the sewage sludge.
