Photochemical technologies assessed: the case of rose oxide

The environmental burdens of the synthesis of rose oxide have been evaluated by means of green metrics (EATOS, LCA) applied to six thermal and photochemical processes. The contributions of supplied energy, employed chemicals (including solvents and additives) and waste disposal have been investigated. The results pointed out that the methods used for the assessment suffered from important limitations. At any rate, the photochemical alternative for this synthesis clearly has the advantage.
