Environmental Performance of the Milling Process Of Malaysian Palm Oil Using The Life Cycle Assessment Approach

Abstract

Malaysia is currently the world leader in the production and export of palm oil. 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 bunch is received at the mill up till the production of the crude palm oil in the storage tanks at the mill. The plantation phase and land use for the production of oil palm fresh fruit bunch is not included in this system boundary. This gate to gate case study of 12 mills identifies the potential impacts associated with the production of palm oil using the life cycle assessment approach and evaluates opportunities to overcome the potential impacts. Most of the impact categories show savings rather than impact. Within the system boundary there are only two main parameters that are causing the potential impacts to the environment; they are the Palm Oil Mill Effluent (POME) followed by the boiler ash. The impact categories that the POME contributes to are under the Respiratory Organics and Climate Change. Both these impact categories are related to air emissions. The main air emission from the POME ponds during the anaerobic digestion is the biogas which consists of methane, carbon dioxide and traces of hydrogen sulfide. An alternate scenario was conducted to see how the impact will be if the biogas was harvested and used as energy and the results shows that when the biogas is harvested, the impact from the POME is removed. The other significant impact is the boiler ash. This is the ash that is produced when the biomass is burnt in the boiler. This potential impact contributes to the ecotoxicity impact category. This is mainly because of the disposal of this ash which in most cases was used for land application in the roads leading to the mil or in the plantations. If the parameters causing these two potential impacts are curbed, then this will be a further plus point for the Malaysian oil palm industry which is already avoiding fossil fuel based energy and chemical use for processing.

Review on Various Types of Geopolymer Materials with the Environmental Impact Assessment

“…Boiler ash can be obtained from the burning of oil palm fiber and palm kernel shells in the boiler where it consists of clinker and ash [10]. POFA is by-product from power plant that generate electricity which used palm fiber, shell and empty fruit bunches as fuel and burnt at 800 -1000 o C [11].…”

Temporal Distribution and Chemical Characterization of Atmospheric Particulate Matter in the Eastern Coast of Peninsular Malaysia

“…Consequently, contribution of biomass burning to air particulate matter concentration from biomass burning could be substantial source. In addition, K and K + in this study could also be attributed to the use of palm fiber and shell waste (as boiler fuel) from regional palm oil mills (Subramaniam et al, 2008). Currently, there are more than 250 palm oil mill plants operating in Peninsular Malaysia with 14 in the state of Terengganu (MPOB, 2007).…”

An Evaluation of Holistic Sustainability Assessment Framework for Palm Oil Production in Malaysia

“…A thorough review of literature published to date suggests that this aforementioned definition could substantially strengthen the framework for assessing sustainability of Malaysian palm oil industries [10][11][12][13][14][15][16][17][18][19][20]. Existing sustainability assessment that involves a number of assessment methods including Life Cycle Assessment, measurement of palm oil sustainability standards and certification schemes have not adequately addressed the sustainability of Malaysian palm oil production due to the following reasons [16,21,22]: the absence of Triple Bottom Line (TBL) assessment, use of ambiguous or unmeasurable indicators (e.g., Criterion 6.11 of Roundtable on Sustainable Palm Oil (RSPO) principles would require growers and millers to contribute to local sustainable development as "wherever appropriate", while the indicator is "demonstrable contribution to local development that are based on the results of consultation with local community".…”
