Abstract: : In the Bioeconomy chain, Biogas is already a reality for large producers. However, there are still difficulties in taking this technology to medium and small producers. Among the difficulties is the issue of sludge temperature. In Brazil, for example, the two states that have the largest swine population (Paraná and Santa Catarina, located in the south of the country) have an average air temperature below 20°C during seven months of the year, which difficult the Biogas production, keeping most of the time in psychrophy range. This research work presents the advantages of an innovative project of a hybrid geothermal/air heat pump for heating the sludge and increasing the production of Biogas. A Biodigester used for 30 cows generated 75 kW/day of gross energy using a 15kW electric power to supply the heat pump.
