Zusammenfassung:	A method for processing lignocellulosic precursors that includes the following steps: 5 A. provide a suitably sized lignocellulosic precursor with less than 25% moisture content ; B. pack a hydrothermal processing vessel with lignocellulosic precursor, such that the density of lignocellulosic precursor in the hydrothermal processing vessel is between 1 and 3 times the free flow density; 10 C. subject the lignocellulosic precursor in the hydrothermal processing vessel to steam below 100 bar for up to 10 minutes; D. slowly reduce the pressure to between 10 and 20 bar E. explosively decompress to ambient pressure; 15 and then dry the resultant lignocellulosic product to below about 15% moisture content.
