Ethanol production and concomitantly sugar from sugar cane is quite satisfactory from the energy point of view, but the large amount of biomass residues generated by sugarcane industries raises concerns from an environmental point of view. Thus, the race for new technologies that aim to minimize the environmental impacts of waste and/or add value and applicability to this waste in the actual production cycle of industries and, above all, investing limited resources is increasing. The hydrothermal carbonization is able to thermally convert wet biomass technique into a rich solid material called carbon hidrochar (or hydrothermal carbon). The main advantage of this technique is the possibility of direct use of biomass in the process without any treatment. Thus, the main waste of the sugar industry, vinasse and sugar cane bagasse, can be used in the hydrothermal carbonization process and provide the final product as a material rich in carbon and other nutrients, which can be used as a slow-release fertilizer. Thus, the aim of this research project is to evaluate the release of the macro and micronutrients and also organic matter, using experiments in columns with different soils and employing amounts of hidrochar produced with waste stillage and bagasse by the hydrothermal carbonization process.
