One of the municipal waste streams is street cleaning waste, classified under code 20 03 03. They are not considered hazardous waste. Due to the lack of other management technology, they are sent to landfills. This waste, among other things, by its high chloride content especially after winter, can contribute to changes in the salinity of surface and groundwater and soil salinization, which consequently contributes to changes in the local environment and entire ecosystems. As it is deposited entirely in landfills, it also contributes to the salinity of leachate generated here. The Regulation of the Minister of Economy of July 16, 2015, on allowing waste to be deposited in landfills, the total organic carbon in waste deposited in non-hazardous and inert waste landfills must not exceed 5% of dry weight. The purpose of this article is to present a study of the quality of the waste on parameters like water content, organic and mineral fraction in the dry weight of the waste, and fractional separation. The water content of the waste ranged from 12–27%, while the mineral fraction in the dry weight was 91–94%. The smallest fraction below 0.05 mm accounted for 0d 1.8 to 4.5%.
