Abstract
A process for treating industrial and/or urban waste includes the steps of drying the waste; effecting thermolysis of the dried waste by direct contact with warm gases, and washing solids resulting from the thermolysis with water to effect dechlorination thereof. Thermolysis is effected by direct contact of the waste with warm gases having a low oxygen content and water for washing the solids is obtained from condensation of vapors generated during drying of the waste A plant for treating industrial and/or urban waste includes a drier for drying the waste, a reactor for thermolyzing the waste, washing the solids from the reactor with water, such as from a condenser, to dechlorinate the solids, and a gas generator to generate warm gases, of which a part of the warm gases are used to heat the drier.
