What are the advantages of dry fermentation versus wet fermentation?
The advantages of dry fermentation are that it has a much less energy intensive than wet fermentation. It eliminates the need for movement of the input material and the addition of liquid. It reduces the volume of the input material by 40% and any generated waste water can be generally be reused for the next batch. BIOFerm plants consume a very small amount of energy themselves, only about 5% of the energy they generate, which is a lot lower than the average consumption of a plant using wet fermentation.
