(WO9623054-A1)      Solid waste material contg. biodegradable solids is collected in a solids digestion vessel at a first location and transported in the vessel to a second location where there is a source of organic material undergoing anaerobic bacterial digestion in a fluid phase digestion stage which produces a fluid fraction contg. active bacteria. At least part of the fluid fraction from the fluid phase digestion stage is fed into the solids digestion vessel to provide at least part of a fluid phase in a solids digestion stage, at least part of the environmentally more acceptable solids fraction from the solids digestion stage being recovered.    Also claimed is the mobile solids digestion vessel used in the process for digesting solid waste material, the vessel having 1 connection for fluids.    USE -   The process and the vessel can be used for treating regularly produced solid organic waste from abattoirs, farms and food processing plants so that it may be discharged into the environment.    ADVANTAGE -   Use of the process and vessel obviates the need for a skip or similar for transporting offensive, smelly, untreated waste, the waste being loaded directly into the vessel at source so as to reduce the amt. of handling necessary and the vessel being sealed to prevent the escape of odours. The treated waste may be unloaded from the vessel at leisure and replaced with a new load.
