Possible ways of utilization of waste chloroorganic compounds have been presented. The methods like isomerization, hydrodechlorination, ammonolysis and chlorolysis have been described. Practical application of these methods allows the management of chloroorganic wastes coming from waste water and waste streams formed e.g. in the production of vinyl chloride by dichloroethane method [2] and in the production of propylene oxide by chlorohydrin method [1]. Four valuable methods of chlorocompounds utilization have been discussed. The first one is isomerization of 1,1,2-trichloroethane [3, 4] to 1,1,1-trichloroethane as the valuable product with a less toxicity than the substrate. The second method is ammonolysis of waste 1,2-dichloropropane and 1,2,3-trichloropropane. Third described method is hydrodechlorination [5, 6] of chloroorganic compounds, especially used for reduction of chlorophenols, vinyl chloride and 1,2-dichloroethan. The last discussed method is the chlorolysis [1, 7]. This method can be used for utilization of all types of waste chloroorganics. Separation of waste chloroorganic compounds by adsorption methods [8–11] has also been described in the article.

Efficient methods of utilization of waste chloroorganic compounds coming from waste water and the waste streams formed e.g. in the production of vinyl chloride by dichloroethane method and in the production of propylene oxide by chlorohydrin method have been presented. First the separation of chloroorganic wastes by the adsorption methods has been described in the article. Three valuable methods of hlorocompounds utilization have been then discussed. The first one is isomerization of 1,1,2-trichloroethane to 1,1,1- trichloroethane as the valuable product with less toxicity than a substrate. The second method is ammonolysis of waste 1,2-dichloropropane and 1,2,3-trichloropropane. The third described method is chlorolysis. This method can be used for the utilization of all types of waste chloroorganics.
