Abstract	The high nitrogen content in wood waste containing urea formaldehyde from furniture industry hampers its utilization as a clean fuel. Herein, microwave-assisted organosolv pretreatment of wood waste using glycerol as solvent was conducted in a commercial microwave reactor with varying temperature of 120–240 °C for reducing nitrogen content. The elemental analysis shows that up to 88.1 % of nitrogen and 92.9 % of alkali and alkaline earth metals in wood waste can be removed by microwave-assisted glycerolysis. The solid nuclear magnetic resonance spectrometry analysis illustrate that the urea–formaldehyde resin, lignin and hemicellulose fractions in wood waste can also be simultaneously reduced by pretreatment. Raw and pretreated wood waste was subsequently fast pyrolyzed in a semi-batch pyroprobe reactor. The experimental results demonstrate that the relative content of levoglucosan in pyrolysis vapors was significantly enhanced by pretreatment, whereas the relative content of nitrogen-containing compounds was reduced obviously. These findings provide a simple and efficient pretreatment method for reducing the formation of nitrogenous compounds during fast pyrolysis of nitrogen-rich wood waste.
