Resumen
The high degree of consumerism that is present worldwide and that is mainly represented in the generation of waste and energy consumption, leads to an increase in the contamination of natural resources and the environment that possesses them. Since organic waste is responsible for 61% of greenhouse gases, biodigesters have been proposed as an efficient alternative for the adequate management of waste, taking into account that the digestion of a mixture of organic waste and water in an anaerobic form by methanogenic bacteria produces methane, which is used as biogas for combustion and electricity generation. A Batch type biodigester was designed and built at laboratory scale, for which factors such as the type of biodigester, the materials for its construction, the electronic components for the census, temperature, pH and a system of blades for the agitation of the biomass were studied; It comprises a system of 3 hermetic biodigesters with constant agitation of 5 to 6 rpm and a temperature of 38°C to 40°C regulated by a thermostat, which from trial and error tests carried out in the water laboratory of the Universidad Santo Tomás, shows its adequate operation to produce between 20 mL to 105 mL of gas with bovine and poultry manure.
