Life cycle inven­tory (LCI) is the heart of a life cycle assess­ment (LCA) study.LCA is a tool to deter­mine the envi­ron­men­tal impacts of a prod­uct at all stages of its life right from cra­dle to grave. In order to carry out a LCA, inven­tory data have to be col­lected and the raw data have to be extrap­o­lated tp pro­duce a LCI. This study has a gate to gate sys­tem bound­ary. The inven­tory data col­lec­tion starts at the oil palm fresh fruit bunch hop­pers when the fresh fruit bunches are received at the mill up till the pro­duc­tion of the crude palm oil in the stor­age tanks at the mill. For this study, 12 palm oil mills were selected. These palm oil mills were selected based on the type of mills which either plantations-based mills or pri­vate mills and have dif­fer­ent pro­cess­ing capa­bil­i­ties of oil palm fresh fruit bunches rang­ing from 20 t hr–1 up till 90 t hr–1. The mills selected are all located at dif­fer­ent zones in east and west Malaysia basi­cally from north, mid south, south Penin­su­lar Malaysia and east Malaysia. Inven­tory data col­lec­tion con­sists of input and out­put of mate­ri­als and energy. The input data basi­cally are inputs of raw mate­ri­als such as oil palm fresh fruit bunches, elec­tric­ity, diesel, water, fuel for boiler etc. and the out­put con­sists of the bio­mass wastes, palm oil mill efflu­ents, flue gases from stack, ker­nel etc. All data were col­lected for dura­tion of three months from each mill. These inven­tory data were then cal­cu­lated for the func­tional unit of every 1 t of crude palm oil pro­duced at the palm oil mill.
