Abstract
The production of bioethanol involves the use of fossil fuels which are
environmentally unfriendly when combusted to produce energy. In view of this,
numerous debatable issues concerning the environmental sustainability of
bioethanol production have emerged. Though the combustion of bioethanol itself
contributes to reduction in greenhouse gas in the atmosphere, their production
processes may offset their pros in terms of environmental safety. In this study,
the environmental impact assessment of bioethanol production from oil palm
fronds (OPFs) was evaluated using life cycle assessment (LCA) tool. Seven
environmental impact categories were estimated with the help of GaBi 4
software. It was found that climate change potential was the highest impact
(5526.57 g CO2 eq.) category for the bioethanol production system. However,
the combustion of 100% bioethanol contributed a reduction of about 85.69% in
greenhouse gas (GHG) emissions. The potential environmentally damaging unit
operations were the oil palm cultivation and OPFs pretreatment units. Reduction
in the use of toxic chemicals and fertilizers could help minimize the nitrous
oxide and carbon dioxide emission which contributed to climate change impact.
