In conclusion, we here demonstrate the first direct conversion of raw lignocellulose, starch, and chitin biomass to GVL. Using 1.8 wt% of the homogeneous catalyst Ru-MACHO-BH in 10.9 M H3PO4(aq) with 30 bar of H2 at 140 °C for 24-120 hours provides GVL in excellent yields (10-26 wt%) from twelve different biogenic or industrially processed biowaste sources, either as individual substrates or a combined pool. This corresponds to 26-48 mol% yields, or an average of approximately 80-90 mol% yield in each reaction step. Furthermore, a number of control experiments reveal that GVL is produced from both cellulose and hemicellulose, allowing to include lignocellulosic material while maintaining excellent yields. Finally, some studies on the catalyst suggest that it remains still intact throughout the reaction.
