What is Assessing Water Footprint for the Oil Palm Supply Chain- a Cradle to Gate Study about?

Water footprint (WFP) has gained importance due to the increase of water scarcity in the world. This paper analyses the WFP the oil palm supply chain (cradle to gate) which produces oil palm fresh fruit bunch (FFB), crude palm oil, palm kernel and crude palm kernel oil. The water accounting and vulnerability evaluation (WAVE) method was used. This method analyses the water depletion index (WDI) based on the local blue water scarcity. The main contribution towards the WFP at the plantation was the production of FFB from the crop. At the mill the burden shifts to the water added during the process which consists of the boiler and process water. There was a 33 % reduction in the WFP when there was no dilution or water addition after the screw press at the mill. When weight allocation was performed the WFP reduced by 42 % as the burden was shared with the palm kernel and palm kernel shell. At the kernel crushing plant (KCP), the main contributor towards the WFP came from the palm kernel which carried the burden from upstream followed by electricity used for the process and transportation of the palm kernel. Two sensitivity analysis was carried out, first for mills with biogas capture v
