Method for economically feasible preparation of organic contaminants, such as volatile organic chemicals and polychlorinated biphenols, even in cases where the contaminants are present in small quantities, from inert materials such as soil or waste sludge, and which method involves the inert materials contaminated with organic pollutants being exposed to a temperature which results in evaporation of the organic contaminants but is below the combustion temperature, with continuous removal and condensation of developed vapours, for a length of time which is sufficient to ensure a predetermined degree of separation of the contaminants. <IMAGE> |
