Imatra Mills
Stora Enso employs 30.000 people worldwide and has 85 production units that produce pulp, paper, packaging boards and wood products to customers globally.
Imatra Mills comprise of two production units: Kaukopää and Tainionkoski. Together they employ around 1.900 people. They produce board and paper. The end products include milk and juice cartons. Imatra Mills produce a million tones of board and paper annually, 90% of which is exported.

Situation
Stora Enso’s Imatra Mills are situated some 250 km east of Helsinki in the town of Imatra on the southern shore of Lake Saimaa. VR Transpoint operates the rail traffic to Stora Enso factories in Imatra. The trains mainly carry logs that are raw material for the mills. On the entrance to Stora Enso’s rail yard, each wagon passes through a laser beam gate that measures the amount of wood the wagon carries. Wagon type information is required for the measuring process. Before implementing RFID, this data was manually received from VR Transpoint and inserted into the system. This process took time as it required manual work and was prone to mistakes.

Given the fact that all VR Transpoint wagons are marked with RFID tags, Stora Enso started looking at the possibility of solving the problem with an automated RFID system.

Solution
The solution is based on Vilant Rail RFID Platform. The Vilant Railroad Reader Unit is installed at the entrance of the rail yard for wagon detection and Vilant Device Manager monitors and configures each unit. The Railroad Reader provides accurate information about the wagons passing through. This information is read from the RFID tags on the wagons.

Vilant Train Analyzer examines the data from the RFID unit and reports the needed information to Stora Enso’s backend system automatically, via a user-friendly web interface. The wagon type data from the RFID system is used to enhance the measuring process.

The system implementation in Imatra mills is integrated into Stora Enso’s back-end system and it is now in production. Stora Enso plans to implement the solution to several other of its mills in the future.
