Valmet to Deliver Bale Tester for Recovered Paper to Papresa's Mill in Spain

The Valmet Bale Tester measures the moisture and other contaminants, such as plastic and ash, of baled recovered paper.

May 15, 2024 - Valmet will deliver a Bale Tester to Papresa's paper mill in Errentería, Spain. The 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.

Papresa's Errenteria mill houses two bleaching plants, three paper production lines, a steam plant and a water treatment plant. Papresa produces 375,000 tonnes of 100% recycled newsprint paper, light fluting, testliner and other specialties paper grades.

According to Valmet, Papresa is currently lacking a reliable system to control the quality of recovered paper delivered to the mill. The 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 Bale Tester has been on the market for over 20 years and has a large, global installed base. Based on the vast number of references, it is expected that Papresa will see raw material quality increase, meaning a fast payback for the investment," said Alvaro Echevarria, Senior Mill Sales Manager at Valmet.

Iñaki Sánchez, Mill Manager at Papresa, explained, "We are really looking forward to getting the Valmet Bale Tester installed. We believe that the real-time measurement system will improve the quality of recovered paper delivered to us, leading to decrease in operational costs and enhanced end-product quality."

The scheduled delivery period will be during the fourth quarter of 2024.
