Economic feasibility study for setting up a biodigester

By Amanda Delfrate, Rafaela Da Silva Limons, Sarah Eloisa Biguelini

Since the economic viability of using biodigesters has been proven, several cities in Paran are already using the method. It basically consists of transforming pig feces into renewable energy through the biomass by-product, biogas. Another by-product that can be used is biofertilizer - an excellent substitute for regular fertilizer. The basis of this work is the characterization of the study region and the subsequent sizing of the Canadian-style biodigester. From the calculations, it was found that the amount of energy used monthly on the property is 449.7 kWh/month, which is less than the amount that would be produced, approximately 2,706 kWh/month. Therefore, the monthly surplus would be 2,256.3 kWh/month, which could be sold to COPEL through a public call - the value adopted for calculation purposes was R$ 0.30. Based on this, the payback time, taking into account the savings on the electricity bill and on the quantity of gas cylinders used, would be around 11 months, making it feasible to implement this form of renewable energy on this rural property in the interior of the municipality of Nova Prata do Igua - PR.
