| Abstract | With increasing attention on sustainable development, the environmental and social relevance of palm oil production are now important trade issues. The life cycle assessment (LCA) study of Malaysian oil palm products from mineral soils including palm biodiesel was aimed to provide baseline information on the environmental performance of the industry for drawing up policies pertaining to the sustainable production. The share of greenhouse gas (GHG) contribution by the various subsystems in the oil palm supply chain is considered here.The life cycle inventory data for the study were collected based on subsystems, i.e., gate-to-gate. The subsystems include activities in oil palm nurseries and plantations, palm oil mills, refineries, biodiesel plants and the use of biodiesel in diesel engine vehicles. Two scenarios were considered: extraction of crude palm oil (CPO) in a mill without and with a system for trapping biogas from palm oil mill effluent (POME). Inventory data were collected through questionnaires. On-site visits were carried out for data verification. Background data for resource exploitation and production of input materials were obtained through available databases and literature. Foreground data for all subsystems were site-specific data from nurseries, plantations, palm oil mills and refineries and biodiesel plants in Malaysia.Using a yield of 20.7 t oil palm fresh fruit bunches (FFB)/ha, the results showed that the production of 1 t of FFB produced 119 kg CO$_{2}$ eq. The production of 1 t of CPO in a mill without and with biogas capture emitted 971 and 506 kg CO$_{2}$ eq, respectively. For the production of 1 t of refined palm oil in a refinery which sourced the CPO from a mill without biogas capture and with biogas capture, the GHG emitted was 1,113 kg and 626 kg CO$_{2}$ eq, respectively. For palm biodiesel, 33.19 and 21.20 g CO$_{2}$ eq were emitted per MJ of biodiesel produced from palm oil sourced from a mill without and with biogas capture, respectively.GHG contribution by the nursery subsystem was found to be minimal. In the plantation subsystem, the major sources of GHG were from nitrogen fertilizers, transport and traction energy. For the mill, biogas from POME was the major contributor if biogas was not trapped. Excluding contribution from upstream activities, boiler fuel and transport were the major sources of GHG in the refinery subsystem. In the biodiesel subsystem, activities for production of refined palm oil and methanol use were the most significant contributors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
