Agribusiness ranks second as the sector with highest greenhouse gas emissions linked to methane, constituting a crucial challenge for global sustainability. Although its impact on climate change is considerable, small rural farmers do not have effective technologies manage organic waste derived from their daily activities. In this context, anaerobic digestion an innovative solution that converts into biogas and biofertilizers, promoting sustainable circular approach. However, implementation faces significant barriers due inadequate designs poor operational practices, which makes adoption difficult in areas. This applied theoretical research seeks overcome these by improving design operation of small-scale plants. The system studied operates at 70% capacity, hydraulic retention time 20 days feed 4 kg matter. substrates considered were 30% bovine manure, achieving average production 63.75 L CH4/kg matter, exceeded usual yields biodigesters. A mathematical model was created case study R2 correlation 98% pseudo-R2 89.5%, evidencing remarkable predictive capacity. plant efficient sustainable, it presented viable farmers.
