In Taiwan, the annual average of rice production was ca. 1.6
million tons in 2001e2005. The rice husk is generated about ca. 0.6
million tons annually after manufacturing of the grain. Besides, the
sugarcane, tall tropical perennials of family Gramineae, plays an
important role in agriculture of Taiwan. There is ca.1 million tons of
sugarcane residues left from refined sugar industry every year.
Therefore, this study selected these two types of prevalent agricultural
residues, rice husk and sugarcane residues, as the feedstocks
for microwave-induced torrefaction tests. The rice husk was
obtained from a rice mill factory in Changhua County in Taiwan,
