August 7, 2023 (press release) –

Valmet will deliver a recovery boiler upgrade to Lecta Group’s Torraspapel combined pulp and paper mill in Zaragoza, Spain. The upgrade will increase the capacity of the pulp mill’s recovery boiler and reduce the mill’s emissions. The order was included in Valmet's orders received of the first quarter 2023. The value of the order will not be disclosed.

The primary target of the upgrade is to increase the recovery boiler’s black liquor capacity. The upgrade will also reduce the mill’s emission levels and improve the water side of the boiler, hence enabling the capacity increase. The upgrade will take place during the mill’s annual shutdown in October 2023. 

"The project will help Lecta to optimize the energy balance of Zaragoza mill as well as make progress in our medium-term decarbonization plan. It also contributes to eliminate a bottleneck for possible future growth in production and/or use of other eucalyptus species. Valmet has always been a reliable and trustworthy supplier for Lecta, with a high degree of technical capabilities in the pulp and paper areas.” says Primitivo Prados, Mill Manager at Torraspapel mill.

“Thanks to our expertise in the recovery area we were able to provide the customer with a strong technical concept and a solution that fits their needs. I believe our good relationship with Lecta Torraspapel will be further strengthened with this project. We will do our best to support the customer in reaching their targets,” says Marcos Gonzalez Moreno, Service Sales Manager, EMEA, Valmet.
