The objective of this research was to characterize the physical and chemical parameters of vermicomposting compost from uncooked organic waste collected at the University Restaurant of the Federal University of Tocantins, campus Palmas. The experiment was carried out using waste collected between March and July 2020 and following the methodology proposed by Lourenço and Coelho (2012). The official analytical methods for fertilizers and corrective measures proposed by the Ministry of Agriculture, Livestock and Supply (BRASIL, 2017) were adopted and the nutrient values were compared to those required by Normative Instruction No. 61 of July 8, 2020. At the end of in the process, 140 earthworms were counted, and a substrate was obtained with conditions of pH and humidity suitable for use in agriculture, but with low nitrogen content, high organic carbon content and nutritional conditions below the minimum requirements determined by the Normative Instruction, for some parameters.
