Characterization of Scots pine stump-root biomass as feed-stock for gasification

► A basis of knowledge in gasification of stump-root systems before and during industry processing. ► Stump-root and stem are great and similar feed-stocks in non slagging gasification. ► Extreme content of extractives induces disturbances during industry processing. ► NIR spectroscopy may be used for on-line quantification of extractives and moisture. ► Functions, regular stand data and drill core analyses can predict usability and amount of fuels.
