Mayr-Melnhof Group, a major cardboard producer based in Vienna, Austria, utilizes the Elastic Stack to manage and optimize their complex production process, which involves producing over 1.7 million tons of cardboard annually. The company deployed over 25,000 sensors to monitor various parameters, such as pressure, temperature, and machine speed, generating around 2 TB of data. Initially lacking the tools to process this data efficiently, they adopted Elasticsearch, Kibana, and Logstash to visualize and analyze production data in real-time, leading to a 20% reduction in the consumption of costly materials within four months. This integration of Information Technology (IT) and Operational Technology (OT) enhanced their ability to promptly address deviations and optimize production.
