Biodigestor Digestión Anaerobia Residuos Sólidos Biodegradables Biogás. The Project began with the establishment of four experimental biodigestors at the Agricultural Research and Practice Centre (Campo de Prácticas Docentes e Investigación Agropecuaria) from the Agribusiness School at Tecnológico de Costa Rica.Biodegradable solid waste from the institutional restaurant was supplied to evaluate biogas production. One of the biodigestors received only wastes, 8,1kg in total. The other one contained 8,1 kg of waste and 5 mL of Índigo® (an organic waste degradation booster), the third one contained 1,5 kg of rice husk and 4,05 kg of waste. The last one had a mixture of 0,4 kg “trasvala” grass (Digitaria decumbens) and 4,05 kg of waste. The temperature was measured at last four days per week with an infrared Fluke thermometer, model 62 Max +, and bubble production was monitored for a 37 day retention period, since this is a biogas production indicator.The institutional restaurant reported an average of 229.16kg of solid biodegradable wastes. By the end of the evaluation period, it was determined that the temperature in the four biodigestors was maintained in a mesofilic range from 20°C to 40°C. The C/N ratio of the analized residues was considered low, reported at 11,26. The organic material was higher thant 50% and pH was reported to have a value of six. The biodigestor that had the better results was the one that included Índigo®. En el Campo de Prácticas Docentes e Investigación Agropecuaria de la Escuela de Agronegocios en el Tecnológico de Costa Rica, se instalaron cuatro biodigestores a escala. Se alimentaron con residuos sólidos biodegradables generados en el restaurante institucional, y otras mezclas, para evaluar la producción de biogás. El primer biodigestor contuvo solamente 8,1 kg de residuos; otro 8,1 kg de residuos con 5 mL Índigo® (un acelerador de la degradación de la materia orgánica); el tercer biodigestor 1,5 kg de granza de arroz más 4,05 kg de residuos y por último, se hizo una mezcla con 0,4 kg de pasto transvala (Digitaria decumbens) con 4,05 kilogramos de residuos. Luego, se realizaron mediciones de temperatura al menos cuatro días a la semana con un termómetro infrarrojo modelo 62 Max +, marca Fluke y se monitoreó la producción de burbujas durante 37 días de retención; ya que estas son un indicador de la generación de gas.El promedio de residuos sólidos biodegradables generado en el restaurante institucional fue de 229,16 kg por día. Al final del periodo de evaluación, se determinó que la temperatura de los cuatro biodigestores se mantuvo en el rango mesofílico de 20 °C a 40 °C. Además, la relación C/N de los residuos analizados fue de 11,26, que se considerada baja. También, el porcentaje de materia orgánica fue superior al 50 % y el pH fue cercano al ideal con un valor de seis. El biodigestor que generó mejores resultados fue la mezcla con Índigo®. 2018-06-29 2020-09-25T23:12:02Z 2020-09-25T23:12:02Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/3633 10.18845/tm.v31i2.3633 https://hdl.handle.net/2238/11805 spa https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/3633/pdf application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; Vol. 31 No. 2: Abril-Junio 2018; 159-170 Revista Tecnología en Marcha; Vol. 31 Núm. 2: Abril-Junio 2018; 159-170 2215-3241 0379-3982
