2. WHY GASIFICATION GREEN TECHNOLOGY COMPLIANT EMISSION & ZERO DISCHARGE LOWER CO2 LOWER SO X & NO X CDM COMPLIANT HIGH EFFICIENCY; REDUCED HEAT RATE COMPLETELY AUTOMATED NO SEGREGATION REQUIRED LOW CAPITAL SIMPLE OPERATION (User Friendly) GREEN TECHNOLOGY COMPLIANT EMISSION & ZERO DISCHARGE LOWER CO2 LOWER SO X & NO X CDM COMPLIANT HIGH EFFICIENCY; REDUCED HEAT RATE COMPLETELY AUTOMATED NO SEGREGATION REQUIRED LOW CAPITAL SIMPLE OPERATION (User Friendly)
