Biosolidis a material rich in organic matter and other nutrients of agronomic importance such as nitrogen and phosphorus. Its end is almost always in landfills. Therefore, its transformation into biochar by the pyrolysis process would be a way to associate its inherent benefits to biochar, enabling a more appropriate final destination. Given this work the objective was to produce biochar in order to evaluate the viability of use in agriculture. The biochar was produced on a laboratory scale at different temperatures and therefore the characterization of the final product was performed. As a result, the material has proven to be rich in organic matter as temperature increases, thinning the material and increasing the specific surface making the alkaline pH serving as carbon sequestration. Thus, with the constant concern of sewage sludge
