摘要
1. A method of rendering reusable plots of land which in particular have previously been industrially used, the soil of which is contaminated with hydrocarbon compounds by deposits, industrial accidents or other harmful incidents, wherein the contaminated soil masses are excavated and are exploited in a manner which does not harm the environment, characterized in that the highly contaminated soil masses together with still present deposits are excavated, are heated on the side at temperatures of 600-800 degrees C and then cooled, reintroduced and recultivated, and that the residual contaminations and hydrocarbons dissolved in the ground water are contracted, while remaining on the site, with growth factors which encourage multiplication of micro-organisms which decompose hydrocarbons, the cooling water used for cooling down the fired masses of soil being used, after enrichment with growth factors, for removing the residual contaminations.
