Abstract

The search for alternative energy sources to replace fossil fuels have caused wastes were generated in the environment. Ethanol production and concomitantly sugar from sugar cane appears to be quite satisfactory from the point of view of energy, but the large amount of biomass residues generated by sugarcane industries generate concerns from an environmental standpoint. Thus, the race for new technologies that aim to minimize the environmental impacts of waste and/or add value and applicability of these residues in the productive cycle of the industry itself and, above all, investing scarce resources is increasing. The hydrothermal carbonization is a technique to thermally convert wet biomass in a solid carbon -rich material called hidrochar (or hydrothermal carbon). Main advantage of this technique is the possibility of direct use of biomass in the process without any prior treatment. Thus, the key residues of the sugarcane industry, vinasse and bagasse can be used in the hydrothermal carbonization process and deliver the final product as a material rich in carbon and other nutrients such as phosphorus, which can be used as release fertilizer slow. Thus, the objective of this research project is to evaluate the release of orthophosphate and pyrophosphate species using different extractants from hidrochar produced using waste stillage and sugar cane bagasse by hydrothermal carbonization process.
