“…Another organic waste from agriculture industries is cheese whey, which is highly polluting, it is produced in milk plants [10], also, its structure contains sugars, proteins and dissolved fats that can be transformed into methane [11].…”

In this research, the whey potential for optimization of biogas production by anaerobic codigestion with cow dung was studied. It used a two-component multifactorialdesign, where it was studied four batch typebiodigesters of 4 liters on a laboratory scale with different whey concentrations (0%, 10%, 30%, 50%) and dilute cow dung in relation 1:1.5, each one in three replications. The experimentation was performed under temperature control of 35°C±2°C; and pH control between 6.4 to 6.9 by the addition of NaOH 3N; with an average of 7% of total solids and a holding time of 35 days. Below these conditions, the 2 nd biodigester with 10% of whey, it was the one which generate the largest amount of biogas with 37.9 liters in total; the 3 rd biodigester, with 30% of whey generates 24.2 liters of biogas;and the 4 th biodigester, with 50% of whey generates 14.5 liters. The reduction of total solids in biodigesters were 38.5%, 43.4%, 40.2% and 27.6% respectively. We used the Gompertz model, which allowed us to find high correlation grades oscillating between 86.295% y 94.268%. Therefore, it can be established, that the use of whey duplicates the biogas production until 52% and sets a limit of 30% (v/v) to obtain a good biogas production in batch-type biodigesters.

Introducción: la producción de biogás es una alternativa sostenible para el aprovechamiento energético de los residuos orgánicos. Esta investigación presenta el estudio y modelación de la producción de biogás, generada por la codigestión de excreta de vaca y suero de leche. Método: se realizaron experimentos de Digestión Anaerobia (DA), utilizando reactores herméticos, a temperatura ambiente monitoreados por 75 días consecutivos con base en el método de potencial bioquímico de metano (BMP). Se utilizaron los modelos logísticos: exponencial de crecimiento máximo Gompertz y Richards modificados para representar la cinética del fenómeno de producción de metano. Resultados y discusiones: se determinó la tasa máxima de producción de metano, la duración de la fase lag, y el potencial de producción de metano acumulado. Se comparó la suma de cuadrados residual y el coeficiente de correlación para identificar el modelo matemático que mejor describe el fenómeno. Se encontró que existe un potencial para la generación de biogás y el aprovechamiento de los residuos experimentados en codigestión. Conclusiones: la experimentación y modelación matemática permitió describir el fenómeno de la producción de biogás, con residuos de la industria láctea y de los sistemas pecuarios. Los resultados de la investigación presentan el potencial de incentivar la producción de energía, en el sector agropecuario regional, a partir de la tecnología DA aprovechando los residuos de la industria láctea bajo el concepto de economía circular.
