Abstract
Lignocellulosic biomass consists mostly of lignin,
cellulose, and hemicellulose, and to a more or lesser
extent other plant components such as sugars, starch,
acids, fats, and oils, and last but not least water
(moisture) and ash. Quality is essentially a set of
biomass characteristics that determine the value of that
biomass type for a certain conversion system. Fundamental
biomass quality characteristics determine if biomass can
be matched to a conversion system. We distinguish
"fundamental" biomass characteristics from thermal
conversion to be chlorine and ash content and ash melting
temperature. For biological conversion, carbohydrate and
lignin are the most relevant, while for anaerobic
digestion biogas yield and digestate applicability are
the most important. Other quality characteristics can
more easily be adjusted such as particle size, moisture
content, and bulk density. It is important to understand
what determines the quality composition of biomass so
that quality can be optimized. Plant type, plant part,
soil type, time of harvest can determine that quality.
