Description

Clariant’s entirely integrated sunliquid® process converts lignocellulosic agricultural residues into cellulosic ethanol or other biobased chemicals in a way that is highly efficient, economic and sustainable. The main process steps include chemical free pretreatment of the feedstock, enzymatic hydrolysis with Clariant’s own proprietary enzymes, that are feedstock-specific and produced process-integrated using the pre-treated feedstock as a substrate. Hydrolysis is then followed by efficient ethanol fermentation simultaneously, converting both C5 and C6 sugars into ethanol and subsequent energy efficient product purification.
