When two firms serve the same region on different days and both leave their containers idle for half the week, a shared pool closes that gap. It needs both sides to use containers of the same size and interface, to accept the same washing standard and to run routes that lie close to each other.

The contract states ownership, counting (who counts and how often), the charge for a lost container, the washing standard and whose line does it, damage, and how containers are divided if the arrangement ends. A count is taken at every handover, and any gap is reconciled the same day with a photo or delivery record.

Labels must carry no customer name, order number or delivery point: if that data passes through a competitor's depot, the ban on agreements and concerted practices in Article 4 of Turkey's Competition Law (No. 4054) comes into play. If a pool operator owns the containers and hires them to both sides, counting, washing and loss management sit in one hand.

The start is one route, a limited number of containers and a six-month trial; if the count reconciles and the loss rate is acceptable, the pool is extended, and if not, each side goes back to its own containers.
