Proposal for the Establishment of Appropriate Anaerobic Biodigestion Technology at the Robeba Farm
Main Article Content
Abstract
The present research was developed on the “Robeba” farm; its objective was to establish the appropriate anaerobic biodigestion technology to be introduced into the farm, transforming waste into biogas and biofertilizer. To do this, the animal species existing in the scenario (cows and pigs) are determined, since these species will contribute the organic waste to the biodigester; Considering the herd movement, the number of animals is determined, which would make it possible to determine the biomass generated daily with the purpose of establishing the sizing of the appropriate biodigester technology and knowing the behavior of the economic and energy parameters. Among the most notable results, it was observed that the implementation of a tubular polyethylene biodigester is more viable compared to the installation of a fixed dome biodigester, representing an economic saving of 19,796 pesos due to technology selection; The necessary volume of this technology must be 20 m3, making it possible to produce 201.3 kg/day of biofertilizers, which represent a daily economic contribution of 2,516 pesos/day (100.65 USD/day), constituting added value, in addition to the energy and economic benefits to be obtained. On the other hand, with the installation of the selected anaerobic biodigestion technology, electrical energy can be produced for the home and the lights, which requires obtaining a 1 kW biogas generator.
