Summary

Descripción general del contenido del recurso.

The search for new energy sources has intensified today worldwide. In Argentina, bioenergy continues to be the energy with minor participation in the energy matrix. Therefore, research should focus on searching for new substrates that increase their production without compromising agricultural systems. This work analyzed the cumulative methane production by anaerobic digestion of cheese whey, a food industry waste, using three substrate/inoculum ratios in volatile solids units. An artificial neural network (ANN) was developed to model the process based on the characterization data (input data) and methane production obtained in the laboratory (output data). The training algorithm used for the ANN was backpropagation. This model's validity was analyzed using statistical parameters such as the regression coefficient (R2) and the mean square error (MSE). The results obtained by the ANN were compared with those obtained by conventional kinetic models, such as the First-order and Gompertz models. The experimental biomethane production was in the range 2325 to 38222 NmLCH4/g VS. The proposed network could predict the experimental data with an R2 of 0.9992 and a training MSE of 2.7598. The statistics used to compare the goodness of fit between the models (R2 and RMSE) were higher for the network, demonstrating its ability to model a complex system such as anaerobic digestion.
