Influence on the Combustion Process of the Type of Fertilizer Used on an Energy Crop (Populus Nigra, L.)


The overall objective of this work was to investigate whether the response to a combustion process was influenced by the material used for fertilizing an energy crop. Hence, black poplar was used as a lignocellulosic biomass crop and three different treatments were applied to fertilize it: digestate from the anaerobic digestion of manure, sewage sludge from the food industry and a control treatment. A thermogravimetric technique was utilized to attain the objective of the study. Thermogravimetric analysis (TGA) is a method widely used for investigating the thermal properties of materials. Non‑isothermal, or dynamic, TGA is more commonly used than isothermal TGA, as fewer data are needed to determine the reaction kinetics. The results showed that the response to a combustion process differed in accordance with the type of fertilizer used on the crop. Similar responses were noted for mineral fertilizers and for digestate derived from an anaerobic digestion process, but when sewage sludge was used the amount of volatile substances released was smaller, regardless of the final torrefaction temperature.
