Abstract
Lignin-rich stillage from 2nd generation bioethanol production is a unique feedstock for slow pyrolysis and biochar production, as it contains high amounts of lignin (62 wt. % d.b) and ash (9.97 wt. % d.b) next to some residual cellulose and hemicellulose. As lignin is known to result in higher char and char-C yields compared to regular lignocellulosic feedstock, the suitability of a lignin-containing residue, obtained from a 2nd generation bio-ethanol pilot run using short rotation poplar, was subjected to anaerobic digestion for biogas production followed by slow pyrolysis of the digestate for the production of biochar.
