3. Economics and Environmental Issue of Plasma Gasification
Plasma gasification process also proves its worth in economic grounds though the initial investment is
very high approx. 150 million dollar, never the less the process pay rich dividend. The Fig.3 shows the
statistics of the process which clearly gives it an upper hand to all other processes.Fig.4 shows a comparison of pollution performance of plasma gasification technology and permissible limit by
Municipal Corporation for combustion of solid waste
4. Conclusion
Traditional methods of solid waste management like composting, landfill and incineration are not very
helpful to completely eradicate the problem of solid waste management. In this gloomy situation plasma
arc gasification has emerged as a breakthrough technology which not only breaks downs the waste into
elemental forms but also produces electricity and essential by-products. The process works on a closed
loop system which safeguards the environment from toxic waste. Economics of the process tells that it
can very viable for growing economies and hence can be happily implemented in the nations like India,
China, Malaysia which produces enormous waste and ensures sustainability of the waste management
process.
