Every plant first collects its tons in its own storage. From there, transport carries them to the nearest suitable warehouse. If no free slot exists, the goods stay where they are.

The research Own Storage enlarges every own storage.
Full is full
If the own storage is full and no warehouse accepts the goods, the plant stops. A large red warning sign appears above it and its character tells you what is wrong. Wages at full load keep running anyway.

Building with own storage
For construction costs everything counts together: all warehouse slots and all own storage. Payment comes from the warehouses first, then from own storage.
