(EP728125-A1)      Process for the biological treatment of organic substances (esp. composting) is claimed. The process is carried out in a closed reactor (RX1 to RXN) in a silo (or pit) (10) and in the presence of biologically active components, esp. microorganisms. The reactor has several reactor zones comprising the silo (10) and at least one reactor gas spaces adjacent to the silo. There are means to set, maintain, control, adjust and regulate the ambient conditions, change these conditions and/or process parameters within the silo (10) through a steady-state, quasi steady-state, and/or unsteady operation of the reactor (RX1 to RXN).    Also claimed is an appts. for carrying out the process.    USE -   The process and assembly provide for composting organic matter on an industrial scale.    ADVANTAGE -   The process and assembly achieve compost of consistent quality at an economic cost.
