The sugarcane straw availability depends on the sugarcane variety and age of har­vesting. The sugarcane straw can be harvested from 10 to 18 tons per hectare on the dry basis ration of straw and stalk (11-17 %). The acceptable ratio of straw to stalk range is 14-18 %, and straw availability depends on sugarcane yield (Leal et al. 2013). The sugarcane straw consists of cellulose (33.3-36.1 %), hemicellulose (18.4-28.9 %), lignin (25.8-40.7 %), extractives (5.3-1.5 %), and ashes (2.1-11.7 %). Leal et al.

(2013) reported that sugarcane straw would be harvested as 62 % dry leaves, 31 % green leaves, and 7 % tops. Top of sugarcane containing higher chlorine may cause corrosion in the fire boilers. The proximate and ultimate analysis of dry matter and mineral of sugarcane straw has been shown in Tables 16.1,16.2, and 16.3.
