บทคัดย่อ

Palm oil production has been growing over the past decade to fulfill the increased demands for vegetable oil and biodiesel. Along with crude palm oil production, a substantial amount of palm biomass is produced, inappropriate management of which would affect environmental performance, and consequently business competitiveness. Life cycle assessment (LCA) has been conducted to assess the environmental impacts of five different palm biorefinery scenarios for empty fruit bunch (EFB) management comparing them with the baseline scenario (i.e. mulching in oil palm plantations). The scenarios include (1) EFB and Palm Oil Mill Effluent (POME) co-compost and cogeneration, (2) EFB based ethanol production and cogeneration, (3) EFB briquette production and cogeneration, (4) EFB compost and cogeneration and (5) EFB cogeneration. The ReCiPe impact assessment methodology was used considering seven impacts categories, viz., global warming, acidification, freshwater eutrophication, marine eutrophication, photochemical oxidant formation, particular matter formation, and fossil depletion. The results revealed that the EFB and POME co-compost and cogeneration (Scenario 1), EFB compost and cogeneration (Scenario 4), and EFB cogeneration (Scenario 5) could help improve the environmental performance of the existing Thai palm oil industry. In terms of economic aspect, the cost-benefit analysis and net present value (NPV) were used to evaluate each scenario’s investment. The EFB and POME co-compost production (Scenario 1), EFB briquette production (Scenario 3), EFB compost (Scenario 4) and EFB cogeneration (Scenario 5) were financially feasible. However, the Scenario 1 was recommended due to the least investment and operation costs and the highest NPV. The EFB based ethanol production (Scenario 2) was not financially feasible.
