Increasing amount of municipal waste is one of the major environmental problems in Turkey. Among several eco-friendly and sustainable methods of waste disposal, plasma technology can be counted as one the most appropriate methods. Considering different chemicals that waste contains, gasification with plasma technology is a much more efficient and safe compared to the conventional thermal disposal methods. Plasma gasification technology is much different than thermal burning. When gasified by plasma, organic compounds of the municipal waste is transformed into syngas. In this research, safe disposal of municipal solid waste and energy production by application of plasma gasification technology to waste and coal mixtures is studied. In this regard two different methods have been used. For the first case transformation of waste with known ingredient mass fractions to syngas and produced syngas is analyzed with a mathematical model. For the second case the same process is studied using a computer simulation software (VMGsim). Results obtained from these two methods are compared and consistency of these two set of results were observed.
