Dangerous industrial waste presents cca 10 % of the total amount of wastes. From the viewpoint of liquidation we divide these wastes into 3 types: wastes containing dangerous materials and compounds not changing their base by thermic treatment (inorganic materials), organic dangerous wastes neutralizable by thermic way, emulsions and suspensions, waterless (or with little water content) organic dangerous wastes neutralizable by thermic way. The oldest method of liquidation of the majority of toxic wastes is scraping, but it has to fulfil rigorous requirements for protection of the environment. The most radical, sanitary, the most effective and almost universal mood is their incineration. Incineration plants must be equipped by very effective cleaning plant. Liquidation of dangerous wastes ought to be realized in centres ensuring also their collection and transport. From the balance of dangerous wastes in the SR follows the need to build up 4 incineration plants with the capacity of 3 500 t r–1 and unavoidably also dumps of incombustible dangerous wastes, because today exists only one incineration plant with ecologically suitable parametres.
