- ItemEnergy balances and greenhouse gas emissions of palm oil biodiesel in Indonesia(Milton Park : Taylor & Francis, 2011) Harsono, Soni Sisbudi; Prochnow, Annette; Grundmann, Philipp; Hansen, Anja; Hallmann, ClaudiaThis study presents a cradle-to-gate assessment of the energy balances and greenhouse gas (GHG) emissions of Indonesian palm oil biodiesel production, including the stages of land-use change (LUC), agricultural phase, transportation, milling, biodiesel processing, and comparing the results from different farming systems, including company plantations and smallholder plantations (either out growers or independent growers) in different locations in Kalimantan and Sumatra of Indonesia. The findings demonstrate that there are considerable differences between the farming systems and the locations in net energy yields (43.6–49.2 GJ t 1 biodiesel yr 1) as well as GHG emissions (1969.6–5626.4 kg CO2eq t 1 biodiesel yr 1). The output to input ratios are positive in all cases. The largest GHG emissions result from LUC effects, followed by the transesterification, fertilizer production, agricultural production processes, milling, and transportation. Ecosystem carbon payback times range from 11 to 42 years.
- ItemRole of biogas and biochar palm oil residues for reduction of greenhouse gas emissions in the biodiesel production(Amsterdam : Elsevier, 2015) Harsono, Soni Sisbudi; Grundmann, Philipp; Siahaanc, DonaldGreenhouse gas (GHG) emissions which related to palm oil production are tend to increase due to the increasing of palm oil demand and the expansion process of oil palm production worldwide. The specific objective of the study was to assess the contribution of innovative biomass processes as effort to improve the energy balance and reduce the greenhouse gas emissions (GHG) associated with biodiesel made from palm oil. The GHG was calculated that GHG emission savings up to 63.14% in total. GHG emissions from biochar using empty fruit bunches (EFB) resulted to 2.95% from total GHG emissions, and biogas from palm oil mill effluent (POME) produced 74.22% of the total GHG emissions from palm oil based biodiesel production. Innovative technologies and processes for the treatment of by-products can contribute significantly for meeting the emission targets. Build upon the research, resulted to the recommendation to use biochar and capturing methane from POME. The research result was also concerned that emission savings are annulled in the case of land use change (LUC) and oil palm production on peatland. Based on this research resulted to recommended that the utilization of waste from oil palm cultivation on peatland which was disuse and the capturing of methane from POME
