The process of producing cellulosic

The process of producing cellulosic pulp from oil palm biomass and other non-wood fibers requires delignification with sodium hydroxide under pressure. This liberates the cellulosic fiber and produces a large quantity of toxic black liquor which is discharged into water bodies without proper treatment [3] and [4]. Oil palm biomass consists of about 20% lignin. This lignin, obtained from the black liquor produced during pulping, is considered as pollutant and it is known to contain about 50% of lignin [5]. Such “go waste toxic products” can be processed into a viable raw material for several industrial applications.
