Abstract:
1. Oxidative treatment of bulk materials in a container and a processing station, which is connected with the container and which processes oxygen into a mixture of oxygen and ozone, the gas mixture, flowing into the container, being mixed with the bulk material that is to be treated and the gas mixture flowing out of the container, provided that it still contains ozone, being purified to remove solids and reduced to oxygen in equipment downstream from the container, characterized in that the bulk material, which is to be treated in the container, is moistened before and/or during the treatment with the mixture of oxygen and ozone gases, so that the moisture content of the bulk material is not greater than 40%, based on the total weight of the bulk material, which is to be treated, and that the end product, present after the oxidation and/or depolymerization, is dried in the container to the desired, final moisture content.
