 Amirobic digestion, AD, is a widely used technology for converting organic waste into biogas and biofatalizer. It involves the use of mixed cultures of bacteria and archaea in a bioreactor to break down organic material into biogas and biofatalizer. This process produces a wide range of intermediary compounds, including volatile fatty acids, VFAs. These VFAs can be recovered and used as precursor chemicals for various industrial applications. In addition, the process also produces hydrogen gas, which can be used as a clean energy source. By optimizing the conditions of the bioreactor, it is possible to maximize both VFAs and hydrogen production.
