Rice Husk Ash - an overview ScienceDirect Topics

A rice mill turns the paddy plant into 78% rice, 20% rice husk and 2% is lost in the process (Ash, 2010). The rice husk contains about 50% cellulose, 25–30% lignin and 15–20% silica (Ismail Waliuddin, 1996). Hence, after the combustion, one-fifth to one-quarter of the rice husk will change into ash.
