Abstract

A process is disclosed for purifying and treating polluted materials by means of micro-organisms. Sludge that contains both micro-organisms that decompose the impurities contained in the polluted materials and the nutrients required by said micro-organisms is added to the polluted materials. The mixture of polluted materials and sludge keeps its shape and its humidity content does not exceed a limit value dependent on the nature of the soil and sludge.
