conducted LCA studies related to the hydrothermal
liquefaction process of algae and microalgae, for biofuels and
bio-jet fuel production, respectively. Due to the limited LCA study
on the hydrothermal liquefaction of lignocellulosic biomass for
bio-oil production reported, it is vital to conduct a LCA study to
gain preliminary insights into the environmental impacts associated
with the conceptual process of oil palm biomass liquefaction
for bio-oil production.
