SEKAB, CelluApp

The technology platform developed by SEKAB uses lignocellulosic materials from forestry and agricultural residues to produce second generation ethanol. An acidic and thermal pre-treatment of the raw material is necessary in the so-called CelluApp Process, before the cellulose is hydrolysed using special enzymes. Resulting C₅ and C₆ sugars from the cellulose and the hemicellulose are fermented by yeasts. Via distillation of the complete slurry, the ethanol is accessed and cleaned. In SEKAB’s chemical plant, ethanol is refined and converted into biofuels and other chemical products.
