The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes place. The temperature of the material during the reaction is one of the most influencing parameter and has to be as much homogeneous as possible, but it is directly connected with the bulk density of the material. From an energy saving point of view, it is advantageous to reach a high bulk density with the lowest water content, but this is in contrast with the propagation of the heat transfer front through the fibrous material.
