Caption : fig. s1 system boundaries of the traditional (red) and innovative (green) route to chlorohydrins: i) continuous line represents the gate-to-gate boundaries within the laboratory; ii) the dashed box is the entire production chain from the raw materials extraction up to the synthesis of the valuable product(s) (cradle-to-gate approach).
*glycidol production using renewables (glycerol) implies the avoided production from allyl alcohol according to the system boundaries in figure s2.
