| Abstract | The formation of sewage sludge (SS) is directly related to the number of people served by municipal wastewater treatment plants (WWTPs), while it is also impacted by increasingly upgraded sewage treatment technologies used in such installations. The presence of SS in our environment raises a number of concerns regarding its proper and sustainable management. In practice, the choice of a specific SS disposal method is determined by a number of factors and, as this research has shown, it may vary significantly both on the national and regional scale. This study analyzed this phenomenon in relation to Pozna & nacute; County, located in the Wielkopolskie province, Poland. As part of this study, the SS chemical composition was assessed based on data obtained directly from local municipal WWTPs over the course of several years (the last 7 years). The currently used SS management methods were analyzed in terms of SS chemical composition. Moreover, in view of the importance of public involvement in decision-making processes related to sustainable management of SS, an original survey was developed to assess local residents' knowledge concerning SS management in Pozna & nacute; County. Based on the obtained data, it was found that the generated SS, constituting a form of fertilizer, was primarily used for agricultural and reclamation purposes (over 41% of total SS mass in the case of Pozna & nacute; County). It is facilitated by the chemical composition of this waste, characterized by high contents of organic matter (380-730.3 g |
