Additionally, while fractional distillation was practical to model during early-stage process development, it is not necessarily the most efficient methodology for CST separation due to the monoterpene's proximity in boiling points. Here, collecting data to investigate other technologies for CST separation, such as reactive distillation, has large potential to bring significant impact reductions for the β-pinene production process. This stands in stark contrast to the LCIA results obtained for benzene production, which are derived from the wellestablished process for benzene manufacture via catalytic reforming of crude oil, and are thus unlikely to represent an overestimate. Therefore, it is anticipated that bio-renewable β-pinene feedstock obtained from a fully developed CST separation process will incur equal or lower environmental impacts than benzene production, irrespective of the allocation strategy chosen.
