Resum: This work is focused on the combustion processes of wood waste. Two kinds of waste have been studied: furniture wood waste (treated and used wood) and solid wood from factories (untreated wood). A kinetic study has been carried out for each material in air and an N2:O2 9:1 atmosphere with dynamic and dynamic + isothermal runs at different heating rates, considering the decomposition of the three main components of the wood and also the combustion of the char obtained. Satisfactory kinetic models were obtained for each kind of wood. Significant differences in thermal behavior were found between furniture wood waste and solid wood, probably due to the presence of additives and inorganic compounds in the furniture wood waste, which modifies the kinetic parameters of the thermal process. Moreover, combustion runs at 850 °C of both kinds of woods were also carried out in a laboratory scale tubular reactor in order to analyze the volatile and semivolatile compounds. The main differences were found in the higher yield of nitrogenated compounds found during the combustion of the furniture wood waste.
