About 8.1 % of waste incinerated in the EU was categorized as hazardous in 2008. The paper aims to assess whether the plants for combustion of industrial and hazardous waste can serve as facilities for energy production. The assessment was performed using a simulation model created in an in-house developed software W2E (Waste-to-Energy). Internal energy consumption under different operational regimes, various lower heating values, temperatures in combustion chambers, air excess and specific flue-gas treatment systems was taken into account; their influence on the available energy production (in the form of heat and/or electricity) and its export was discussed. It is highlighted, that two-stage combustion of industrial and hazardous waste may be associated with significant supplementary fuel consumption. The energy introduced into the combustion chamber by this fuel, usually natural gas, reduces overall positive impact. Attainable specific production of heat and electricity and specific primary energy savings criteria were evaluated for several technological concepts of combustor design. Obtained results indicate that combustion of industrial and hazardous waste can reach "energy recovery" status under only specific operational regimes. These conditions are discussed in more details.
