The compressed body is crushed after drying and hardening.
This may be carried out in any suitable manner, in particular by using a hammer mill with a removable grid for passage of the crushed material. This allows for example a proportion of fibrous materials derived from textiles, plastics and cellulosic materials contained in the initial waste to be mixed with mineral materials such as glass, limestone or organic materials contained in this waste. A ground material is obtained having a proportion of fine particles resulting from the crushing of.
