Optimization of the Design of a Pilot Biogas Production Unit for Rural Areas

Designing a biodigester that allows treating organic waste from cattle to obtain biogas in rural areas is a challenge in biomass management and productivity indices. The design of the biodigester was carried out considering a possible increase in the size of the cattle. The amount of manure available and the amount of biogas expected to be produced were also estimated. In addition, a metal dome was selected to facilitate access to the interior of the biodigester and to be able to carry out its maintenance in a simpler way. Graphs were added that show the minimum values of manure collection that allow its profitability. The most notable conclusion of the project is that for biodigesters in rural areas, biogas represents a minimal fraction of the profit that can be obtained through the project due to its low production, so the commercialization of biol is considered the main source of income.
