ABSTRACT
This paper presents results of work on the reduction of toxic metal content while decreasing its oxygen activity. During the study the effects of different doses of ozone in the air used for aeration of the stabilized compost in the first post-thermophilic phase were analyzed. The results showed the possibility of reducing the concentrations of toxic metals and decrease the activity of oxygen up to 30% compared to traditional stabilized compost aeration system without using ozone.
