Abstract

Coturniculture, as an activity which demands low investment and quick return, is shown to be a possibility for the rural family producer. Concomitant to this, we highlight the fact that the use of liquid quail farming waste, aimed at generating energy by anaerobic digestion, can mean a viable and promising technology for obtaining biogas from confined animal production systems. The growing demand for energy establishes that new energy sources are better used, and a great opportunity for their growth may be the use of biomass in anaerobic digestion systems, in which the organic substrate is degraded and transformed into energy and biofertilizer. The method applied was Biochemical Potential of Methane, through benchtop bioreactors with a volume of 250 mL, and in mesophilic conditions. Waste was used as inoculum from the manure tank of the quail egg production farm. The substrates used to compose the treatments were liquid quail farming waste from the water depth treatment system, with 15, 30 and 45 days of deposition. In the results obtained, it was verified that the best mono digestion used was inoculum+substrate of 30 days of deposition, with water retention time of 45 days, showing a higher production accumulated in biogas (0.00078476 Nm3) and CH4 (0.000575 Nm3) as well as the highest biogas potential of 0.0043 Nm3 (kg substrate)-1. When converted into electrical energy, by means of a motor generator, using as fuel the biogas produced by the liquid quail farming waste, the value of 104.64 kwh (45 days)-1 was obtained.
