I need to create a LCA process for the production of a product containing Calcium Peroxide (>75%) and Calcium Hydroxide (<25%), but I cannot find any data about the production of these chemicals anywhere. My idea was then to use the data of a similar chemical (maybe hydrogen peroxide?) but I don't know if I should eventually add/modify something from that one. Dis anyone have a similar problem, or anyone know how I could fix that?

Thanks in advance.
