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 fully utilised joint product have no alternative production routes, then the normalised market trend for these will be equal (or close to equal), due to the fixed proportions of the outputs, and these joint products would therefore enter as a group into the third step of the three-step procedure here, and this group of products could therefore be identified as co-determining for the joint production.

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.
