Global statistics shows that the number of cars worldwide is increasing every year, leading to an increase in the number of worn-out tyres, for which efficient and safe recovering is a problem. There exists a variety of technologies that help get raw materials from recovering worn-out tyres or use them as a source of energy. Recovery of worn-out tires is an urgent necessity worldwide. In accordance with the European Union Directive 1999/31/EC, burial of refuse tyres is prohibited and as an alternative they would have to be recycled. On the one hand, the increasing pace of industrialization is causing ecological problems; while on the other, worn-out tyres are valuable raw materials. A case analysis study – assessment of environmental impact of the performance process of a tyre recovering plant in Lithuania (hereinafter – the object) – was performed. For the object assessment, qualitative and quantitative data acquired by experts during inspection were used. In the study, the authors assess and analyze the impact of potential technogenic risks of the object processes on the environment and population. The aim of the research is to perform risk identification, assess potential consequences and determine their amount. On the basis of the data acquired at the object the authors of the study find out what shortcomings exist in the process of recovering of worn-out tyres, what is the actual situation in the safety system at the object and what are the environmental consequences of emergency situations. The main hazards are caused by the risk of tyre fire, because such fire is very difficult to extinguish and harmful smoke is released as a result of combustion thus contaminating the atmosphere with substances harmful to the environment and human organism. Tyres are combustible material, additional hazards include ecotoxic effects. It was found that at 100-metre distance from the epicenter during fire of the tyre housing concentration was 1.07·10-7 %. Thus, dangerous consequences for people within 100 meters at the ground level are not associated with dangerous concentration of carbon monoxide.
