The aim of this study is to evaluate pyrolysis as an effective method for the disposal of mixed municipal solid waste while simultaneously obtaining energy-rich products. Thermal behavior was analyzed using TGA and DTA to assess mass loss and identify endothermic and exothermic reactions. The study demonstrated that the main portion of gaseous products is released within the first 15–20 min of pyrolysis, with methane accounting for up to 53% of the total gas volume. The yields of solid residue, liquid fraction, and gases were found to depend strongly on temperature, with optimal pyrolysis occurring at 450–550 °C. Within this range, an efficient release of volatile compounds, increased hydrogen yield, and higher calorific value of the gas were observed. Increasing the temperature above 550 °C did not result in a further rise in heat value, indicating the influence of the morphological characteristics of the waste on the composition of the final products. The study examines the potential of pyrolysis to convert complex solid household waste—including paraffin materials and synthetic rubbers—into valuable products such as fuels and chemical feedstocks.
