Process Trend

Enzymes…

are proteins that act as catalysts

are highly specific

are renewable and biodegradable

operate under mild process conditions

can replace chemicals in many areas of industrial production

Polishing Methods

Standard

• One-pot method (caustic wash without phase

separation)

In Development

• One-pot hybrid (modified wash with reduced caustic)

• Resin process

• Enzyme esterification

Other options

• Blending

• Modified glycerol polish
