The most significant contributions to the overall environmental impacts of the proposed process were found to stem from the manufacture of paracetamol from β-pinene. Figure and Table show that the impacts associated with paracetamol manufacture are much larger than the impacts of β-pinene feedstock production across all impact categories. This is unsurprising, as significantly more processing steps are involved in paracetamol manufacture from β-pinene than in β-pinene production from CST. To understand what aspects of paracetamol manufacture from β-pinene incur the most impacts such that future process optimisation can effectively target environmental process hotspots, an in-depth hotspot analysis of process steps I -VI was carried out.
