<p>The invention relates to a method and apparatus for treating waste with a predominantly solid matrix containing vaporizable substances, in which the mass of waste is heated in a restricted environment to a temperature of from 120 to 170 °C by the generation of heat by internal mechanical friction. Most of the vaporizable substances are extracted from the mass of heated waste by the metering, onto the mass of heated waste, of a fluid which can evaporate within the aforementioned temperature range so as to generate a stripping flow which is evacuated from the treatment environment, the quantity of fluid metered and the heat generated by mechanical friction at the same time being regulated in a manner such as to keep the temperature within the range of values defined above during the extraction stage.</p> |
