A halohydrocarbon is destroyed chemical-thermally by reacting at 600.degree. to 800.degree. C. with calcium oxide and/or calcium hydroxide. The process can be carried out problem-free by having the calcium oxide of hydroxide present in at least twice the stoichiometric excess based on the halogen to be bound and by having the composition contain 2-30 wt. % iron oxide.
