Valmet is to deliver a bale tester to Papresa's paper mill in Errentería, Spain. Valmet bale tester is a reliable and real-time measuring system for recovered paper, providing an opportunity to reduce operational costs and to improve the recycled fiber line performance.

The value of the order will not be disclosed. The scheduled delivery period will be during the Q4 2024.

Papresa is currently lacking a reliable system to control the quality of recovered paper delivered to the mill. Valmet bale tester measures the moisture and other contaminants, such as plastic and ash of the recovered paper. The information is automatically stored in the mill's database, analyzed, and further utilized for optimizing the production process.

Valmet's delivery will include the installation of Valmet bale tester On-truck solution, extended with ash and lignin sensors and related software, the system's start-up and a spare parts package. The On-truck model measures the raw material samples directly from the bale onboard the truck.

At the Errenteria mill it houses two bleaching plants, three paper production lines, a steam plant and a water treatment plant.
