More than one co‑product without alternative production routes
As a general rule for joint production, there will be a maximum of one determining co-product from each co-producing unit process. But a special situation arises when more than one co-product from the unit process have no alternative production routes.
When more than one co-product from a joint production have no alternative production routes, all of these co-products will be separately determining.
Under this heading, you will find examples where the situation of “more than one co-product have no alternative production route” is identified. The further procedures and examples on how to calculate the consequences of a change in demand for one of the determining products are provided under a separate heading.
