    Hospital waste due to its specific properties (radioactivity, toxicity or infectious) needs proper waste management. The most popular method of hospital waste treatment is incineration. By-products of incineration are slag, fly ash and waste coming from the treatment of an exhaust gases. The objective of this study was to examine physico-chemical properties of hospital waste slag after incineration, which are humidity, pH, CaCO3 content, heavy metals concentration (Cd, Cr, Ni, Pb) and heavy metals leachability (EN-type leaching test and TCLP). The obtained results revealed that only pH of the leachates exceed permissible values regulated by law. Leaching of heavy metals do not exceed standards and therefore hospital waste slug can be commonly used, e.g. for the production of road aggregates.

    Termiczne przekształcanie odpadów jako ekologiczny sposób na ich zagospodarowanie

    The aim of this study was to assess the possibilities of municipal waste management system in Poland. Theoretical and legal issues were delineated, particularly concerning municipal waste, including landfilling and incineration. Statistical data was used to formulate three scenarios of increasing waste generation until the year 2040. Based on statutory methodology and the capabilities of incineration plants in Poland, theoretical energy and heat generations were estimated, along with corresponding financial gains. Data gathered from 38 landfilling sites allowed the estimation of the average price for municipal waste landfilling and enabling the calculation of the total cost of waste landfilling in the scenarios created. The cost of waste admission into incineration sites was also considered. The analysis concluded that waste incineration is a crucial element closing the waste management system. Not only is it economically viable, but it also helps to avoid significant environmental pollution.
