American Value Added Pulping® (AVAP)
Sulfur dioxide, ethanol and water cook of biomass
Key process differentiators
• High sugar yields and highly digestible cellulose fiber provide low operating and capital
cost process
• High purity cellulose fiber can provide glucose stream suitable for non-volatile
chemicals, hydrophobic chemicals and catalytic chemical processes
• Works equally well on softwoods, hardwoods and agricultural residues
