Pulp & Paper industry

VA Teknik has finalized the installation of a new Rotating sludge scraper to Stora Enso papermill.

Sales & Business Development Manager Marko Kunerus

“It´s a huge challenge in these projects with the papermills, they have a short period when they stop the 24/7 operations for a week long maintenance break. During that week there is a huge amount of work that needs to be done. As example at this mill they have around 700 employees and during the break there are a thousand contractors coming in to do all the repair, maintenance and exchange of equipment to ensure safe operation when the startup is due. The planning and the project management need to be top of the line to ensure the safety during this intense period.”
