2. INTRODUCTION
Rapid industrialization and urbanization have led to increase in solid waste and depletion of natural energy resources.
Global generation of Solid Waste will double by 2025.
Solid waste generated by 300 million people living in urban India is 30 million tonnes per year.
1,00,000 MT SW generation every day in India.
Plasma gasification is the unique opportunity to mitigate the above challenges.

3. PLASMA + GASIFICTION
Plasma gasification is a process which converts organic matter into synthetic gas, electricity, and slag using plasma. A plasma torch powered by an electric arc, is used to ionize gas and catalyze organic matter into synthetic gas and solid waste (slag).
Plasma is a fourth state of matter.
Man made plasma produced by plasma torches using electricity as a heating source and air as ionized gas.

4. Gasification
Process that converts carbon-containing materials (MSW, biomass, coal, etc.) into a synthesis gas
Syngas = carbon monoxide and hydrogen
Syngas is a “cleaner” fuel than the original solid feedstock, resulting in cleaner emissions (reduced NOx, SO2)

5. Plasma Gasifier
Gasifier is the central component of the plasma gasification process.
The plasma arc converts organic waste into synthetic gas and inorganic material into vitrified slag.
The chemical reactions take place are
C + H2O = CO + H2
C + CO2 = 2CO

6. Advantages Clean destruction of hazardous waste
Production of  value-added products (metals) from slag
Production of vitrified slag which could be used as construction material
Processing of organic waste into combustible syngas for electric power and thermal energy

7. Conclusions
Plasma gasification holds a potential to add to the supply of renewable energy resource in these times of uncertain energy supplies.
Any material can be processed in plasma arc system. To achieve a favorable energy balance the volume of inorganic should be minimized.
There is no emission of harmful greenhouse gases. Concentrations of dioxins are very low as compared to incineration due to high temperature.
Plasma gasification technology has a high operating cost and capital cost due to high electrical power requirement
