INTRODUCTION:

• BIOENERGY- one of the most important components tomitigate greenhouse gas emissions and substitute of fossil

fuels.

• Need of energy is increasing continuously, because ofincrease in IN!"#RI$%I&$#ION and 'O'!%$#ION.

• (on)entional sources of energy*

- petroleum, coal, natural gas, hydro + nuclear.

• I"$$N#$GE* - $tmospheric pollution,

- GG

- NO, "O, (O, 'articulate matter

and )olatile organic compounds.
