Bio fertiliser production in the oil palm industry has so far cincentrated mainly on the wastes from palm oil mills, but has excluded the refinery waste discharged by the palm oil refineries (POR). There are now 59 POR, and the generation of SBE has increased to 240 000 t annually. For the past 30 years, SBE has been condemned as an industrial waste due to degradation of the residual oil in it, and the associated greenhouse gas emissions upon its disposal. Thus, there is some urgency to research on and to solve the problem by exploring the possibility of 100% recovery of SBE.
