The cost of unplanned downtime in pulp and paper mills
Unplanned downtime in pulp and paper mills is among the most expensive losses in the plant because a single failure, such as sheet breaks and machine stops that are slow to recover, can stop the flow, not just one asset. The true cost pairs lost contribution margin with emergency labour and expedited parts, and is usually several multiples of the repair itself.
