The continuous supply of Oil palm (Elaeis guineensis) biomass in the form of “wastes” provides enormous opportunities to efficiently utilise the constitutive naturally occurring biopolymers such as cellulose, hemicellulose and lignin. The greatest challenge is to apply an environmental friendly technology to fractionate, isolate and purify the constitutive biopolymers involving the pretreatments of the raw plants biomass follow by subsequent refining processes. This paper describes the pretreatments procedures involving hydrothermal processes and the aqueous extraction processes to isolate green chemical in the form of biopolymers from various part of oil palm plant (Elaeis guineensis) wastes. Depending on the severity of hydrothermal pretreatment procedures, cellulose, hemicellulose, lignin and other minor constituents were fractionated and isolated in varying quantities and properties. The green chemical obtained; in the form of biopolymers, were analysed and characterised for their functional properties
