Biochar: Production, Characterization and Applications
Biomass consists of four main constituents, cellulose, hemicellulose, lignin and minerals. The first two, are the key targets for various conversion processes producing biofuels and chemicals, leaving behind different forms of lignin, depending on extraction process used.

Biochar: Production, Characterization and Applications
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.
