Maximizing methane output is key to biogas plant efficiency, and fish offal, with its high fat and protein content, offers a significant energy boost, potentially yielding up to 2.5 times more methane from fats and 1.5 times more from proteins than carbohydrates. To harness this energy fully, adding carbohydrates is essential for microbial activity.
The strategy of blending fish offal with carbohydrate-rich substrates, like cattle manure, not only enhances methane production but also ensures the biogas process’s stability. This approach effectively leverages waste materials, optimizing methane yield and making the biogas plant more productive and sustainable.
