The work was carried out through pre-composting and vermicomposting. In the pre-composting and vermicomposting the treatments were tested: T1 (4:1:1 - Sheets + goat manure + DOW), T2 (4:1:0.5 - Sheets + goat manure + DOW), in the proportion of DOW in terms of volume, where the unit of measurement was a 15 L bucket. The pre-composting process was conducted over 30 days and the temperature was monitored daily. At the end of the pre-composting and vermicomposting process, the monitoring was carried out by means of humidity, pH, electrical conductivity, total carbon, total nitrogen, C/N ratio, phosphorus and potassium analyses. In addition to the chemical characterization of the compounds, worm counts were performed at the beginning and end of vermicomposting. In the second stage of the process, the maximum temperature reached was 39º and 36ºC after the 30th day, in treatments T1 and T2, respectively. In the third stage, the final pH was in the range of 6.4 to 6.6. The T1 treatment provided better adaptation of the worms. The values for C/N ratios reduced in all treatments, indicating the maturation of the compounds. Although the treatments do not present all the conditions required for commercialization, the work shows the feasibility and potential of using biodegradable organic waste to produce vermicompost as a practical and sustainable alternative for fertilization.
