TECHINICAL FEASIBILITY OF BIOGAS PRODUCTION BY IMPLEMENTING A BIODIGESTER AT SUPPLY CENTERS OF GOIÁS

This approach is an appealing alternative for energy production in Brazil, which is the largest fruit and vegetable producer worldwide. Parameters such as pH, stirring, temperature, and FOS/TAC ratio were continuously evaluated for process optimization. Results demonstrated that this process could reach a biogas production (60% CH₄) of 1.200 m³/day, equivalent to 788.4 MWh/year, taking into account an energy conversion factor for biogas with 60% methane adjusted to 1.8 kWh/Nm³. It encourages the continuity of optimizations for increasing biogas production and, consequently, to continue towards a sustainable energy generation economy.
