[a] All calculations performed for 5 mmol limonene, for details see the Supporting Information. [b] Carbonate isolation was not included in PMI calculations. [c] Calculations do not include waste generated during start‐up, before the flow reactor achieves steady state. [d] No data is available on commercial preparation of limonene oxide, mCPBA oxidation was chosen as an example: 5 mmol limonene, 5.5 mmol mCPBA, 5 mL DCM, assumed 90 % yield. [e] See Figure 8. [f] See Table 3, entry 2.
