Use of the boniga of the Santa Teresita Dairy for the production of electrical energy

A technical design and an economic analysis of the boniga utilization system of the Santa Teresita dairy was presented for the production of electrical energy. The total energy demand of the farm has consisted of 3,294 kWh per month, and the required power has been 18.7 kW. Field visits to the dairy were carried out to determine its conditions and count the amount of boniga available. Topics of biogas generation and electricity generation from biogas were investigated. The interviews with professionals were developed on the topic of use of renewable energy, use of organic waste, electricity generation. The design of biodigesters currently in operation was investigated in the country. An economic analysis was carried out to determine the cost of inputs for the construction of this energy use system and the profitability of the project. The farm has shown that it can become energetically self-sufficient. The economic indicators have shown an IRR of 31% and a NPV of 15% of ₡11,290,452, so the project is economically attractive. The implementation of the project has shown that the release of greenhouse gases would be avoided by 77 cubic meters of methane per day
