AB The valorization of urban solid waste compost (MSW) intwo different composting conditions (different aeration and humidity) hasbeen studied (we work with the hypothesis that the composting process canhave a significant influence on a subsequent pyrolysis process). Theinfluence of composting on subsequent pyrolysis of the material wasassessed by examining the kinetics of the process, maximizing hydrogenproduction and minimizing the activation energy. The thermogravimetricanalysis carried out on the samples have shown that they have a greater lossof weight of 9−14% at 270−275 °C and 22−27% at 444−446 °C. Using theKissinger−Akahira−Sunose method, the activation energy values are foundto be in the range of 57.78−581.69 kJ mol−1, and the assumption that pyrolysis of compost could be modeled by a first-orderreaction may be a suitable approximation. The analysis of the gases produced from the pyrolysis process revealed that hydrogenincreases in concentration as composting time advances until intermediate time. In this form, the composting process could be asuitable previous treatment for improving the pyrolysis process. In fact, decreasing aeration and moisture in the MSW compostingprocess led to the production of an increased amount of hydrogen (8.3%) by pyrolysis of the resulting compost and also to adecreased activation energy (102.8 kJ mol−1). These effects were also observed before the end of the composting process in the formof maximum hydrogen production and minimum activation energy after 20 days.
