In the modern world, a special place is occupied by rational usage of the waste sludge from municipal wastewater treatment. There is always an open question for finding local solutions for the problems related to sewage sludge disposal. The aim of this paper is to sublimate the results of the research performed within the national project "Investigation of the possibility of chemical and technological treatment of sludge from the treatment of municipal wastewater treatment plants and producing complex fertilizers", which took place in two phases. The first phase of the research was laboratory and semi-industrial investigation of waste sludge from the Vranište Waste Water Treatment Plant plant near Struga. In the second phase, the field trials were set out to define the effects of the use of the produced organic mineral fertilizer. It was found that organo-mineral fertilizers derived from sewage sludge seem to be suitable for application to the soil. Therefore this work initiates multiple solutions that cover environmental effects and economic benefits from such treated product. In the absence of national legislation applicable to this problem, the European Union suppositions have been used.
